Do you have the part number/application for the clutch disc? The information you provided is great for a transmission swap.

 

I bought it at Autozone as they are one of the few who will sell just the disc. It cost me almost what the transmission did.

Part Number: D4220
Alternate Part Number: NCP3348

This is listed as a clutch disc for a 1995 C1500 with a 5.0L V8, just make sure the clutch says/or measures 11" and 1-1/8 unless of course your truck has the smaller 10" clutch.

There may also be a Ford version with that spline count but I did not look very hard for it.

 

Thank you Jules The Great for sharing your project. What a neat job you did. I have read it with interest as I am also working on installing a NV4500 in my 1950 F5 truck to replace the T9 crash box. I will be taking a little different approach, however. But, I also need a diagram with the dimensions of the input shaft and front bearing retainer as you have drawn in step 4 though for a 49-52 as I believe the input is shorter. If anyone has a T98 or a T9 out of a 49-52 laying around I would love to have the dimensions as shown in step 4 of this thread and would be glad to compensate someone. It would save me from pulling and reinstalling the transmission only to have to remove it again down the road.

I would be careful about trusting anyone's measurements including mine.

You have a thread on your install? I think it is a prefect transmission for the bigger trucks.

 

I don't have a thread on the install. I have not done any work thus far as am still getting my parts together. But, I am ready to start fabricating the adapter plate.

Jules, this is an interesting swap.

Nelson, I have a T9 and a T98 out that I can measure. They are different so, I can send you the info on the T9 since that is what you have. I will try to get them to you later this week.

I actually did the same thing, I measured the input shaft on Buddy's transmission(lives nearby) That way I would not have to pull mine out just to measure it. I also borrowed a bellhousing from him to do all the mockup work easier. That way I could machine up all the needed bits and just bolt it in when ready.

Can't wait to see your thread on how you do yours Nelson.

Thank you Mark

 

Thank you for the replies. Mark, thanks for the willingness to measure that up. That will save me alot of work. Jules The Great, my truck has the Marmon Herrington 4x4 conversion. I purchased a early Chevrolet 4x4 version of the NV4500 which I will adapt to the back of it a Ford NP203 transfer case which is a full time four wheel drive unit. I have learned that that adaptation is not a big deal. I need to change the NP203 input shaft to a Chevrolet 32 spline input and drill up the NP203 range box to the desired clocking and pattern of the transmission. My understanding with this model of the NV4500 is that the input shaft is about an inch longer than the T9 I have. That will give me room to adapt to the flathead 6. My plan is to simply mount a T9/T98 front bearing retainer to one side of a approximately 1 inch thick piece of aluminum plate and then machine the other side to receive the NV4500 while maintaining a center. I will probably have to cut off the throwout bearing portion of the NV4500 bearing retainer. But, that won't be used anyway. Using the old bearing retainer will alow the use of the factory parts between the engine and transmission with the exception of the clutch disc and pilot bearing. I have already purchased a clutch disc for the new configuration and there is a conversion pilot bearing for Ford flathead to Chevrolet transmission available from Speedway. I have over-simplified the project, but that is it in a nutshell.

By the way, if anyone has a 49 to 52 T9 or T98 front bearing retainer they would like to part with, PM me I am interested.

What clutch disk did you get? Is it flush on the flywheel side or does the spring pack protrude? Is the flywheel recessed to allow the friction material to contact?

I am not sure I fully understand your plan. You could start a thread with a rough drawing/sketch?

 

Jules The Great,

I was planning on altering as little as possible within the bell housing. I just needed to find a clutch disc that was identical to the factory disc with the exception that it takes a transmission input shaft size of 1.125 inches instead of 1.375. So, I purchased the following clutch disc which is fairly flat on the flywheel side i.e., it looks very similar to the disc the 49-52 Ford manual illustrates. When I received it I checked it on the NV4500 and it slides very nicely onto the splines. The only other part that I will have to alter within the bell housing is the pilot bearing. As I mentioned before, Speedway offers a pilot bearing for flathead Fords that will receive a Chevrolet transmission input shaft. That is all I should need to do within the bell housing.

I don't feel as though I am ready to start a thread as all I have done is some thinking and buying parts. I need to know dimensions of the T9 input shaft before I can buy the aluminum plate. As soon as I buy it, I can start actually doing some work.

Mark,

The measurement for the input shaft from the transmission to the tip should be around 5.75 inches. I bring this up as a sanity check for having the applicable transmission to measure.

Thanks for the interest,

Nelson

 

I hope that clutch works out for you. I know the Y-block flywheel is flat all the way too about a 5" circle in the center

 

 

Nelson, I think the above post are the dimensions you are looking for. I hope you can read them ok, I had some trouble scanning and downloading them. Let me know if you need anything else.
Mark

 

Mark,

Those drawings are beautiful man! Thank you.

I do have another question. Is there a wear mark on the input shaft as to how far it protrudes into the pilot bearing? If so, will you measure that for me? That will help me understand how much room I have to play with concerning how thick the adapter plate can/should be.

Thank you again,

Nelson
