Requesting info on upcoming split
 

I've put off repairs on my 147 long enough. I bought it in April '12 and it's time to go through it and get it to work better. More specifically, from the drive shaft back.

Currently it has a drive shaft with a plastic fan. Yes it works, but it's missing a blade, and I bought a better one in summer '13. It creeps, and it's got the typical hydro issues (slow uphill, speeds up downhill, and will go into reverse when the brake pedal is depressed.) it leaks hydro fluid, and who knows what's in the rear end. The PO had been using universal hydraulic fluid from TSC.

What I'd like to do to it:

Replace drive shaft with one that has correct metal fan. Install fan shroud (since I currently do not have one.)
Install relief valve flap. Mine is gone.


Address the trunnion. I'm sure the issues described above is because of the trunnion being worn.

Replace cork gasket. (hopefully this is the source of the leak)

Do a neutral adjust.

New fluid.
New filter.

New rag joints?

Obviously I need to do a split to make this work. I've got the service manual and have been reading up on how to do it, but I was hoping to get as much info on things to look out for, (like what typically is worn and needs addressed) and tips on a successful repair, before I go tearing into it later this spring. IE how to (have someone) weld up the trunnion without ruining the pump with too much welding heat, etc. All and anything that you'd be willing to point out that would help it go well. I feel confident enough mechanically to do the repair, but I want to make sure I know fully what I'm getting into before I actually do it.

Thanks!

Here's some info:

I always put a wet rag over the shaft to keep the seal from getting hot and to keep the sparks out, but truthfully a quick buzz in each corner with a mig is all it takes. I don't think there is enough heat there to get anywhere near the shaft. I have seen pictures of the square holes that were pretty bad and did need a little more welding, but if it's that bad don't weld it all at once.

This is my stock answer for trunnion problems.

If you have or suspect that you have trunnion problems with your Cub Cadet hydro, start by going here.

There is a lot of good debate here.

After you have fixed your trunnion your forward-reverse lever and foot pedal may be out of wack, so go here.

Personally, I see no need to add extra metal pieces to the square hole, unless the ends are worn crooked. I have never had this problem with any that I have fixed. So I simply weld the slots in the corners and then file them back square again.

I think someone said one of my links is dead, I don't know for sure, haven't checked them in awhile.

Yeah Daniel, it's not a big deal fixing the trunnion, hell if I could do it on nearly every tractor I own, it'll be a breeze:biggrin2: for you.
As mentioned, the amount of heat your going to use to close up the corners isn't a big deal, but for the "just in case" wrap a wet rag around the shaft and over the pump. You'll be golden:beerchug:
Oh yeah, take it from the expert, (me) do not clean out the differential with paper towel on a hydro either, it's to easy to not get every piece out, and the pickup tube frowns on that:biggrin2: Jon will get a laugh out of that:bigthink:

youll be fine, its not like tearing an automatic trans drown or anything...i used key stock on my trunnion,i like that its harder and with the extra thickness, should take 100 yrs at least to wear again....

What's up with the universal hydraulic fluid? Is there something to be worried about, I'm changing trans fluid soon and was thinking about buying it...

in my opinion theres nothing wrong with a good universal fluid, ive used it in every hydro tractor ive ever had with no problems. just make sure the fluid is none foaming and it should be fine.

OK, those were my thoughts too. $70 for 5 gal of Hy-Tran is nuts!

I don't feel like there is anything against using uni-tran myself. Why I'm replacing it is because I've never had the rear end open and I don't know whats in there. (ice, water, gunk, etc) Plus, when I refill it I can get hytran cheap(er) so that's going back in. (and it smells better.)

These are all great links and great tips. Thanks guys!

Yep, they're pretty proud of Hytran aren't they. :biggrin2:

I use Hytran, others have used universal without issues, so use what you're comfortable with. I agree with Olds on the non-foaming oil.
