  2. Service History: Ask for any service records. A well-documented maintenance history can indicate that the previous owner took care of it, which is key for a diesel engine.

  3. Engine Performance: Start the truck and listen for any unusual noises. The 6.9L engines are generally robust, but look out for excessive smoke or rough idling.

  4. Transmission Health: Since it’s a 4-speed manual, check for smooth shifting and unusual noises. Test it under load to ensure it operates well.

  5. Interior and Amenities: Inspect the interior for wear and tear. A clean interior can indicate lower usage and better overall care.

Red Flags to Watch Out For

  1. Rust and Body Damage: As mentioned, rust can be a huge issue. Don’t just look at the surface—check underneath and in places that are hard to see.

  2. Engine Issues: Look for signs of oil leaks or coolant leaks. A diesel engine should run smoothly without excessive smoke or knocking sounds.

  3. Transmission Problems: If the shifting feels rough or if there are any grinding noises, that could signal trouble ahead.

  4. Electrical Issues: Check that all the lights, gauges, and electrical components work as they should. Older trucks sometimes have wiring issues, especially if they’ve been modified.

  5. Suspension Wear: Given the age, inspect the suspension components for wear and tear. A rough ride could indicate worn-out shocks or bushings.

Final Thoughts

If everything checks out, and the price is right, you might have a great deal on your hands! Just make sure to take it for a test drive and perhaps have a trusted mechanic inspect it if you’re hesitant.

What are the advantages of converting a 1984 F250 from 2WD to 4WD using a Dana 44 straight axle?


Bullnose Bill explaining the 1984 F250 2WD to 4WD conversion process.

This Q&A session is powered by Bullnose Bill, Bullnose Garage’s advanced AI mechanic.
Have your own question? Ask Bill!

Bill says:

Converting a 1984 F250 from 2WD to 4WD is a big project, but definitely doable. Going with a Dana 44 straight axle is a solid choice — especially if you want a more straightforward and durable setup compared to the Twin-Traction Beam (TTB) alternative. Let’s break it down.

Why Choose a Dana 44 Solid Axle?

  1. Simplicity: The solid axle with radius arms and coil springs is less complex than a TTB setup. That means fewer moving parts to maintain and replace.

  2. Durability: Solid axles are generally more robust, which is a plus if you plan on doing any heavy-duty work or off-roading.

  3. Aftermarket Support: A solid axle swap has a lot of community support and available parts, including lift kits and custom fabrication parts.

Steps for the Conversion

  1. Front Axle Swap:

    • Remove the existing 2WD suspension and components.
    • Install the Dana 44 axle. You’ll need to ensure you have the proper brackets for mounting the radius arms and coil springs to your frame.
    • Make sure the axle is correctly aligned and centered.
  2. Transfer Case Installation:

    • Swap out the 2WD transmission or modify it to accept a transfer case. A transmission with a removable tailshaft is ideal.
    • Install a transfer case compatible with your transmission. The NP205 or NP208 are common choices.
  3. Driveline Modifications:

    • Fabricate or source new drive shafts for both the front and rear. Length and yoke compatibility will be crucial.
    • Ensure the U-joints are properly aligned to avoid vibrations.
  4. Steering Adjustments:

    • Modify or replace the steering linkage to accommodate the new axle.
    • Consider a crossover steering setup if you’re looking to improve handling and reduce bump steer.
  5. Brake System:

    • Adapt the brake lines for the new axle setup.
    • You may need a proportioning valve to balance the brake force between the front and rear.

Pros and Cons

  • Pros: Improved off-road capability, increased durability, and a straightforward setup compared to TTB.
  • Cons: Requires cutting and welding, driveline modifications, and potential challenges with legalities or inspections.

Potential Pitfalls

  • Alignment: Proper alignment of the axle and radius arms is crucial. Improper setup can lead to handling issues.
  • Parts Compatibility: Ensure all parts like the transfer case, drive shafts, and steering components are compatible with your setup.
  • Budget: This swap isn’t cheap. Consider all costs, including unforeseen ones, before diving in.

What are the differences between the ZF5 S42 and S47 transmissions in a 1987 Ford F350?


Bullnose Bill explaining ZF5 transmission differences for 1987 Ford F350.

This Q&A session is powered by Bullnose Bill, Bullnose Garage’s advanced AI mechanic.
Have your own question? Ask Bill!

Bill says:

Ah, the 1987 F350 with the mighty 460! That’s a great truck you’ve got there. As for your ZF5 transmission, it can be a bit tricky to identify between the S42 and S47 when there’s no tag present, but I can help you narrow it down.

Generally, the S42 has a slightly shorter gear ratio compared to the S47, and it’s often found in lighter-duty applications. The S47, on the other hand, is designed for heavier loads and has a more robust structure.

Here are a couple of ways to help you identify which one you have:

  1. Gear Ratios: The easiest way to differentiate between the two is by checking the gear ratios. If you can get access to the transmission and operate it, the S42 typically has a first gear ratio of about 5.61:1, while the S47 has a ratio of around 6.34:1.

  2. Input Shaft: If you have a way to measure the input shaft length, the S42 usually has a shorter input shaft compared to the S47.

  3. Physical Dimensions: Sometimes, looking at the physical size and the shape of the transmission can provide clues. The S47 is a bit bulkier, especially around the bell housing area.

If you’d like to dive deeper into this topic, I recommend checking out the Bullnose Garage YouTube channel or forums like the F150 Forum and the Bullnose Ford subreddit. There are plenty of folks there with hands-on experience who can lend a hand!

Is it possible to replace a ZF5 S42 with a ZF5 S47?

Bill avatar

Bill:

Absolutely! You can use a ZF5 S47 in place of a ZF5 S42, but there are a few considerations to keep in mind to ensure a smooth swap.

  1. Mounting Points: The transmission mounting points are generally the same, so you should be able to use the same crossmember. Double-check alignment to avoid any issues.

  2. Driveshaft Length: The S47 might have slightly different dimensions than the S42, especially if there are variations in gear ratios. You may need to adjust your driveshaft length or reconfigure its angles to prevent any vibrations or wear.

  3. Shift Linkage: Ensure the shift linkage is compatible. While they should generally be interchangeable, you may need to adjust or modify the linkage to fit perfectly.

  4. Gear Ratio: Since the S47 is usually geared for heavier loads, you might notice a difference in performance. It could mean a more robust feel when towing or hauling, but it might also change how your truck feels under normal driving conditions.

What does the casting number 130730108 4.4 signify?

Bill avatar

Bill:

Great job finding that casting number! Based on the casting number you’ve provided, 130730108 4.4, this generally corresponds to the ZF5 transmission, specifically indicating that it’s likely an S47.

The "4.4" part often refers to the output shaft diameter, but the most definitive way to confirm it’s the S47 is through the overall build and characteristics of the transmission as mentioned earlier. The S47 is designed for heavier-duty applications, which aligns with your 1987 F350 and its capabilities.

Where is the casting number located on the transmission of a cab and chassis 4×4 truck?

Bill avatar

Bill:

Thanks for the clarifying details! If the casting number is on the passenger side and your truck is a cab and chassis 4×4, that can impact the type of ZF5 transmission you have.

In cab and chassis configurations, Ford often used the ZF5 S47 due to its robust construction and ability to handle the additional weight and towing demands that come with those setups. The S47 is typically found in heavier applications, which fits well with the cab and chassis design.

Keep in mind that the layout and gearing of 4×4 systems can also influence the transmission’s characteristics. If you’re planning on any modifications or repairs, having the S47 means you might have a bit more durability for heavy towing or off-road use.

If you’re considering swapping or replacing parts, ensure you’re sourcing components that match the S47 specifications. Also, feel free to reach out to the Bullnose Garage community or the forums for any specific advice related to cab and chassis models!

How does the 450hp with a 4.10 ratio and 31-inch tires affect 0-60 times?

Bill avatar

Bill:

Estimating 0-60 mph times can be a bit tricky since it depends on several factors, including weight, traction, and tuning. However, with a well-tuned 1986 Ford F150 equipped with a 351 Windsor producing around 450 horsepower, a 4.10 gear ratio, and 31-inch tires, you’re likely looking at a 0-60 time in the ballpark of 6 to 7 seconds, assuming good traction and a proper launch.

Keep in mind that a lot of variables can affect this time:

  1. Weight of the Truck: If you’ve got a lot of extra equipment or a heavy load, that will slow you down.

  2. Tires: The type of tires you have can significantly affect grip and acceleration. Performance tires will give you a better launch than all-terrain ones.

  3. Transmission Type: If you’re using a manual transmission, your shifting skill will play a big role in your acceleration. An automatic with a good torque converter can help you get off the line quicker.

  4. Tuning and Fuel: Proper tuning and using high-octane fuel can help you maximize that horsepower, leading to better acceleration.

  5. Launch Technique: How you launch the vehicle can impact your times. Too much wheel spin or launching without enough power can slow you down.

What is the largest tire size suitable for a stock-height 1983 F100 302 AOD?


Bullnose Bill discussing tire size options for a 1983 F100.

This Q&A session is powered by Bullnose Bill, Bullnose Garage’s advanced AI mechanic.
Have your own question? Ask Bill!

Bill says:

Fitting larger tires on your 1983 F100 with a stock height setup can give it a beefier look and possibly improve traction. However, there’s a limit before you’ll start rubbing issues, especially when turning or going over bumps.

Stock Setup and Maximum Tire Size

  • Stock Tire Size: Typically, the stock size for these trucks was about 235/75R15.
  • Maximum Tire Size: On a stock suspension, you can usually go up to a 31×10.5R15 without major issues. This size should clear the fenders during normal driving conditions.

Considerations

  1. Rubbing: If you go bigger, especially in width, rubbing might occur on the inner wheel well or suspension components.

  2. Speedometer Accuracy: Larger tires can throw off your speedometer reading. You might need to recalibrate it or live with the speed difference.

  3. Performance: Bigger tires can affect acceleration, fuel economy, and braking performance due to increased mass and rolling resistance.

  4. Gearing Impact: Your axle ratios matter. Larger tires effectively raise your gear ratio, which can reduce torque at the wheels. Not a big deal, but it’s worth noting with a 302 and AOD combo.

If you’re looking for more detailed advice or have a specific setup in mind, there may be a related video on the Bullnose Garage channel to check out. And if you’re curious about what others are running, the Bullnose Ford subreddit (reddit.com/r/bullnoseford) is a great place to see what other enthusiasts are doing with similar setups.

Can I fit 33-inch tires on my 1983 F100?

Bill avatar

Bill:

Fitting 33-inch tires on your 1983 F100 with a stock suspension is pushing the limits a bit more. While it’s not impossible, you’ll probably face some challenges.

Potential Issues with 33s

  1. Rubbing: It’s very likely you’ll experience rubbing at full lock or when hitting bumps. This can happen on the fender wells and possibly on suspension components.

  2. Trimming and Modifications: To avoid rubbing, you’ll probably need to trim the fender edges or modify the wheel wells. It might also require adjusting the suspension with a small lift for better clearance.

  3. Performance Impact: The extra weight and size can noticeably affect handling, acceleration, and braking. It’s even more pronounced with a stock engine and the AOD transmission.

  4. Gear Ratio: With 33s, your effective gear ratio changes significantly, which can reduce low-end torque and impact drivability, especially if your truck isn’t geared for it. You might consider a regear if performance drops off too much.

  5. Speedometer Calibration: With larger tires, your speedometer will be off, and you’ll need to recalibrate it for accurate readings.

Recommendations

If you’re set on running 33s, consider a small lift kit to facilitate proper clearance. Alternatively, rolling or trimming the fender lips might suffice depending on how aggressively you drive.

For more ideas and setups others have tried, you might find useful discussions on the Bullnose Ford subreddit (reddit.com/r/bullnoseford) or potentially related videos on the Bullnose Garage channel. Always good to see what solutions other folks have come up with!

Going with 32-inch tires on your 1983 F100 at stock height is a bit more feasible than 33s, but still requires some consideration.

Fitting 32s

  • Rubbing: You might still run into some minor rubbing issues, especially at full lock or when hitting a bump. This is less severe than with 33s, but something to watch out for.

  • Minor Modifications: Depending on your specific truck and its suspension setup, you might get away with just minor adjustments, like possibly trimming the fender lips or adjusting the inner fender wells.

  • Performance Impact: As with any tire size increase, expect some impact on performance — reduced acceleration, slight drops in fuel economy, and possibly more strain on your brakes.

  • Gear Ratio Changes: The impact on your effective gear ratio is less dramatic than with 33s but still present, so keep an eye on how your truck feels, especially in terms of torque.

  • Speedometer Adjustment: As with any tire size change, you’ll want to check your speedometer for accuracy and recalibrate if necessary.

Practical Steps

  1. Check Wheel Backspacing: Ensure your wheels have the proper backspacing to help minimize rubbing. This adjustment can sometimes help fit larger tires without major mods.

  2. Test Fit: If possible, try to test fit the tires before purchasing. This gives you a sense of clearance and any issues upfront.

What are my options for retrofitting A/C in my 1983 F100?

Bill avatar

Bill:

Retrofitting or upgrading the A/C system in your 1983 F100 can make a big difference in comfort, especially if you’re dealing with an older system or one that’s not functioning well. Let’s look at your options and what you need to consider.

Common Retrofit Options

  1. R12 to R134a Conversion:

    • Overview: The original A/C systems in these trucks typically used R12 refrigerant, which is now obsolete and expensive. Converting to R134a is a common upgrade.
    • Components to Replace:
      • Compressor: Ensure it’s compatible with R134a or upgrade to a newer model.
      • Condenser: Consider a parallel flow condenser for better efficiency.
      • Drier/Accumulator: Always replace this component when opening the system.
      • Orifice Tube/Expansion Valve: Replace for optimal performance.
    • Seals and O-rings: Make sure all rubber components are compatible with R134a.
  2. Vintage Air Systems:

    • Overview: Vintage Air offers complete aftermarket systems designed for classic vehicles. They provide modern A/C performance while integrating well with the original design.
    • Pros: More efficient cooling, modern reliability, and often cleaner installation.
    • Cons: Higher upfront cost and may require custom work for perfect fitment.
  3. OEM Replacements:

    • Overview: If you’re keen on keeping things closer to original, you can replace the key components with OEM or equivalent parts designed for R12 but adapted for R134a.
    • Considerations: Availability can be an issue, as not all OEM parts are still in production.

Tips for a Successful Retrofit

  • Flush the System: Before switching refrigerants, thoroughly flush the system to remove all traces of the old oil and refrigerant.

  • Check for Leaks: Use a vacuum test to ensure there are no leaks before charging the system with the new refrigerant.

  • Professional Help: If you’re not comfortable with A/C systems, consider having a professional do the retrofit. Proper handling of refrigerants is crucial for safety and legality.

  • Resources: If you’re interested in a DIY approach, there may be a related video on the Bullnose Garage YouTube channel that walks through an A/C retrofit.

Bill says:

Hey there! Swapping from an automatic to a manual transmission in your 1986 F150 with the 351W is a fun project that can really transform your truck!

For your setup, one of the easiest manual transmissions to swap in would be the T18 or T19, which are both robust options. They were commonly used in the Ford trucks of that era and are known for their durability. The T18 is a four-speed and offers a good balance for both on-road and off-road use.

Another solid choice is the NP435, a four-speed transmission that’s also compatible with your 351W and offers a good low gear for off-roading.

Here are some steps and considerations for the swap:

  1. Transmission and Tailhousing: You’ll need the transmission, bellhousing, and tailhousing from a compatible manual setup. Make sure to match the input shaft length to your 351W.

  2. Clutch Setup: You’ll also need a clutch pedal assembly, master and slave cylinder, and all associated hydraulic or mechanical linkage.

  3. Driveshaft: Check if your driveshaft needs to be modified or replaced. The length might change depending on the transmission you use.

  4. Crossmember: You may need to modify or replace the crossmember to fit the new transmission.

  5. Wiring: Don’t forget to disconnect any wiring related to the automatic transmission — you won’t need it anymore!

  6. Shift Linkage: Pay close attention to the shift linkage. Depending on your chosen manual transmission, you might need to fabricate or adjust the linkage for proper fit.

This swap can be a bit of work, so take your time and enjoy the process! If you want to dive deeper into specifics, you might find some helpful guides or videos on the Bullnose Garage YouTube channel. They often cover swaps and modifications that can really help out!

Feel free to reach out if you have more questions or need specifics on a certain part of the swap. Happy wrenching!
