1958 350 Utility PTO Addition????

Anonymous-0 · Apr 24, 2009

My tractor (58 Gas w/TA) was not optioned with a PTO when purchased. I have found one at a salvage yard on the same model and year of machine but I am not sure what is required to add it to mine. I have looked at the CNH parts site but they show a trans drive and independent types. Which one is right for my machine? Would love to add one to make this tractor more functional but I want to do it right. Is $400 for the used PTO a fair price? Any help would be greatly appreciated.

To the best of my knowledge, the Independent will work. Not the trans driven.
The TA system determins if it can be used, or not. NO TA (Factory delete) means trans driven only.
TA on tractor will be equipped for IPTO.
You may need all the parts and shafts. See caseih.com for detailed parts required. JimN

Just checked the CNH parts site for more info and am more confused! There are listings for IPTO and TPTO with the TA. Under the TA breakdown there are parts listed to be used with an IPTO. Can I assume that these parts are already in mine? Not sure how the internals were done when a PTO was not optioned from the factory. I have removed the PTO cover plate from the rearend to look around. There is a splined shaft extending from the transmission into the rear end housing. It appears to be were the coupling would hook up for the IPTO. Also what fluid was used in the rearend, is it shared with the trans/TA. I drained apx 6-7 gals out of it. Smells like gear oil but I have heard HyTran should be used in these areas. Thanks in advance. Chris

Chris, is the PTO you've found still mounted on a tractor? If so, the chassis serial numbers might be handy. Yours should have a suffix of either R (for TA with provision for transmission PTO) or S (for TA with provision for independent PTO. At the least, that should define what yours is equipped for and, if the other is still on the parts tractor, and the number plate is still there, will tell you which type PTO you're looking at.

If it's not on the tractor, does your research in the catalogs show any difference in part numbers that you might be able to find (like the housing or a gear) that would tell you which it is?

TA equipped tractors use Hytran. Hopefully it still has the serial tag, thus the R or S mentioned by Scotty. I have not looked into the rear end, if you know what you are looking for you might be able to tell. One sure way is to split the tractor which is a lot of work if you find the thing won't fit. IPTO equipped tractors have a hollow shaft that the drive shaft fits into. The hollow large pto shaft is splined to the main clutch pressure plate, the drive shaft is splined to the clutch disk. Transmission driven will have only one small shaft splined to the pressure plate AND disk. After all this, a simpler way is to determine if the IPTO is a large external square box, as opposed to the smaller round PTO housing on the TPTO. I have not seen a TPTO on a 300 -- you might study the diagrams on the parts book more closely.

You indicate your tractor has a T/A, if it has a S letter after serial # all you should need is the live pto unit, shifting parts and the shaft just ahead of pto. After pto is removed you can reach in hole and pull shaft out with 2 splined couplings, or they may come out with the pto unit.
If your tractor has the letter R after serial #, you will need to remove center housing and change 2 pto drive gears in housing, add the drive shaft from clutch plate to T/A used with t/a and Ipto, and maybe the clutch pressure plate if yours is not equiped with splines.
$ 400 sounds high to me. Have bought whole rear ends with PTO cheaper.
You can also remove the pto cover on your tractor with front a good bit lower than rear to save on oil draining. Look around 16 inches ahead of opening for splines at lower transmission shaft. With clutch disengaged brakes locked and transmission in gear, have someone bump starter. If the splines turn your good to go. If they don't turn or no splines a tear down and other parts would be needed.

Forgot to say you need the pto unit with a vent on top and a upside down bath tub shaped metal cover with one screw in the middle, cover is on right side top. If you could get the in and out shift parts a planetary pto from several tractors will work. One from like a 400 would need the adapter plate between it and trans. housing. shaft ahead of pto is the same for both size transmissions.

Just cleaned 50+ years of crud off of the S/N plate and found 9576 S. I haven't had the help yet to bump the starter, maybe in a couple of days. But it sounds like I may be in good shape according to your previous advice. I would like to express how much I appreciate all the advice from everyone. Having a resource like this is invaluable for working on something almost twice as old as I am! Hope to post some pics soon to share my pain, er, JOY! Thanks again Chris
