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!
