Info On Parts
 

I was wondering if any of you folks have used any parts for your NV4500 or any other job From USA Standard Gear? I see summit Racing, Rock Auto, sells their parts, I am going to replace my input shaft in my NV4500 its a little messed up from the pilot bearing leaving this earth. I was going to just put a sleeve on the input shaft but I have never used a speedy sleeve for a input shaft before, I have used them for harmonic balancers with great success.
I am not sure but this shaft is most likely made in china, The more I ask this question The more I think about sleeving it and using the factory shaft. I sure don't want to do this job again in my driveway on my Back and with 375000 miles on her AND I'm repairing a rotted frame now with 1/4 inch U channel steel, Not sure how long she has.
Or any advice on where to get a GOOD input shaft? I see some made in India some in China, I'm Leaning more towards sleeving it..

Thanks, any info will help.

Fragile
WELL, DONT Buy one from Rock Auto, I DID , and the gear was hanging out of the hole in the box and banging on anything it could hit on That FedEx truck, I found the package with gear face down on my concrete steps, Needless to say I Never open it and it went Back. OK, Now the next place.

I'd go for the speedy sleeve if possible. It fixes what went wrong and you still have the bearing preload as is.
Naturally I'd inspect the shaft, but usually you just use the sleeve and everything is fine again.

Sleeve
 

The only speedy sleeve I see is not for the end of the shaft, I Think it is for where the seal rides on the input shaft, My factory shaft has wear on the end where the pilot bearing let go. So that's why I am going to have to buy one.
Thanks.

It depends- if you have access to a lathe you can turn the "pin" the bearing rides on to a smaller diameter and get a bearing with smaller ID and same OD, or turn a sleeve that you can shrink on there and get to the original OD of the pin. That's what goes for speedy sleeve for a bearing over here.

Will be new
 

No wont be doin that, Just need to find a reputable place to buy one, Will call the cummins dealer today to see what they offer.
Maybe I will call the local parts stores also.

Thanks for your input:Cummins:

Cummins dealer does not deal trans parts usually.

If you install a new shaft you will need to check the clearances and preloads, meaning you will need to re-shim the trans.
Do you have the manual for the trans, the tools and the shims?

Yes
 

Yes I have everything Needed, Except a input shaft.

Well it took almost 3 months BUT in there was about 40 days of rain, And rain is not good in my open air garage (driveway), BUT the NV4500 is FINALLY done, The only factory part's I couldn't find was a input shaft and Main Shaft, I bought the input shaft from a trans shop in cali Made in India. And the main shaft from a trucking company in Idaho, The rest were factory parts.
I bought several other parts and when they were shipped to my house the packing job they did sucked, so when you see a gear or whatever hanging out of a hole in the side of the box,, YOU send it back. Look at this photo of the side by side reverse clutch gear I bought from ***state gear, (don't know if I can say the name of company on this site) Really, They want me to use that, Look at the teeth on the inside that slide onto the main shaft almost non existent compared to the factory one, sent that back, Delayed again. Also the same with their snap ring kit which I did not use.
I DID end up with an extra reverse synchro hub, made in Taiwan, I have to say that it does look pretty good, at least they wrapped in the old style brown wax paper to prevent rust, I do have to say that.


Ended up putting in a main shaft, Input shaft, all main bearings- same Timken bearings Part # that came out of trans-, new reverse clutch gear, Reverse synchro hub, reverse snap ring ,synchro kit ,pocket bearing , thrust bearing , 1st , 2nd ,3rd and 5th gear Torrington needle bearings, Teflon spacers, new National Seals, shift boot , New Clutch Set , Machined flywheel , New Rear main seal , all new U Joints , Center Bearing, the only 5th gear nut fix that really works, probably a couple other things also I forgot about.
Then to find out the Specific tranny fluid part #04874459 has been discontinued, But I did find 10 quarts at a dealership 25 miles from my house. YES I know the trans hold almost 4 quarts.
I know,,, you guy's are going to tell me what fluids to use,, You guys use what you want, I will use the factory fluid that I got 376000.00 miles with changing it once in there before the rebuild.

It is so nice to be able to upshift AND actually downshift NORMAL again with NO grinding NO double clutching like when the truck only had 90 thousand miles on it. She has 850 miles on Transmission now and workin great.



I have already repaired my frame Rot , And have replaced both rear shackles, Today I put the first coil spring bucket in, Next week I will do the second one.


The fun NEVER ends, Like the song says, RUST Never sleeps... I think I will have that painted on the tailgate..

This looks good!

I know that you will use the correct fluid and you will have fun rowing gears for the next few hundred thousand miles. (Anything less than 5 is few)
