350 TA Questions

Bought a cheap 350 RC and it has TA problems. The TA did not change the speed when the lever was moved. I adjusted by the manual and decided to drain and refill with new oil while in the shop. The oil had a lot of water in it so I pulled to top plate off to see what it looked like and try to clean it out. After I got the plate off, I noticed the TA clutch seemed to be gone. I can see parts of the disc in the bottom of the housing. If this is the case , is it pulling on the low side now? PO said it freewheeled. Is there a way to delete the TA or is this a big expense? Am I correct that the tractor has to be split in two places to do anything to it?
 
If it is operating it is in TA low. The TA clutch disk is the direct drive. Splitting at the front is required to replace the clutch, but replacing bothe the clutch, and the one way ramp and roller clutch by splitting twice is not much more effort, and puts it into operation. The TA is good because it is being used full time. The cost of deleating it is way more than the cost of the parts to make it great. Kevin Meier (Frequents here) sells parts and is reasonable. HiCapacity is also a good brand name. Jim
 
here is essentially what your gonna have to do in order to service your TA. this is a 450, but its exactly the same for a 350

having a shop cat is purely optional.......
 
Thanks for the reply. I will decide if I want to just replace the clutch or do more. If it is now working in the low or TA then it is possible that just the clutch would make it work as it should?
 
I've seen this picture before but I focused more on the cat!

This time I noticed the regulator. Is this a 450lp from the factory or a conversion? I'm curious about the manifold. I have one that has the cold manifold and I have an M that was converted using a 400/450 tank and has the same manifold you have here. I'm wondering if that is a later gas manifold or just a variation in the LP parts.

If the tractor works fine now on just the low side you can get by with just a single split and replace the TA clutch.

Most likely it still had the riveted lining rather then the bonded one. The riveted one do tend to fly apart if they are allowed to free wheel at too high a speed.
 
You lucked out! This is the EASY fix.

What Owen said. All you need to do is split at the clutch housing and replace the TA clutch.
 
Thanks for all the help. I am sure I will have more questions as I get into this project. I think when time permits I am going to split and go from there. Hopefully just the TA clutch will be the fix. The tractor probably won"t ever see heavy work as I just saved it from the scrapper and really don"t need it. I am not really concerned about having a TA but don"t want it just working in the low side and freewheeling.
 
Thats a gas manifold used on 450 and as a gas manifold replacement for M to 450 for a number of years. During SM LP production a manifold with exhaust and intake runners separated from each other started being used and continued on through 450. No ribs joining them like the one in the picture. Early SM LP used the same manifold as a gas SM.

she's a factory 450LP. i have another 450LP and it has the exact same manifold
 
They came with a manifold like this. Lot of them cracked and I suspect IH made the gas replacement manifolds longer than the LP ones because of less demand for LP ones. At the time manifolds were replaced the gas may have been the only one available. Aftermarket is making the LP ones now.

guess of the 4 LP's i know of they've all broke cuz they all four have the same manifold as whats in my pic.
 
You can check it out in a parts book or maybe online. Probably can see the # on at least one of those manifolds. One you have pictured is # 362437R2. LP calls for # 358308R1 in the picture I posted. Just pointing out the difference and hope it doesn't upset you.

im not upset at all. i just have only seem to have seen the manifold like i have. ive got two, cousin has one, and a friend has the fourth and they all must have been replacements for the one that was original.

was the original a two piece?
 
Don't have a LP manifold now, from what I remember there a one piece only joined at the head mounting flange. They are pretty much the same manifold you have now without the joining ribs. Most of the LP manifolds I removed in the past have some kind of crack on the head side of the outlet opening.
 
Ok, that makes sense. I haven't looked close at a gas 450. My SM Lp's both have the correct manifold but I have seen a Stage 1 SM with the gas manifold and the tractor seemed pretty original. In fact that tractor is for sale now that I think about it.

Thanks for the help.
