John Deere 350C clutch rebuild

Hi I have recently acquired a reasonably honest 350CB (loader) and it came cheap as the clutches need doing. There are so many kits and videos out there on doing the dry clutches in the earlier models and nothing that I've found on the wet clutch of the C series.
The question I desperately need answered are which parts would be usually replaced, aside from the obvious discs, plates and brake bands. I'm thinking that it would it be usual to do the pilot bearing. Beyond that there are several clips and rings as well as the piston, are these generally re-used?
As my user name suggests I am in Australia and I'm going to have to source most of the parts myself from the US as they are not locally available. For that reason it's more economical for me to get the parts and replace them rather than to open it up and have a look before ordering and then have the mechanic cursing me while the machine sits waiting for parts to arrive.
Hopefully someone has done this and can share their experience. Thanks in advance.
 

I am guessing you find less info on the wet steering systems than the dry ones when you search is because they give way less trouble. Since they run in oil, the rusting swelling and sticking often encountered with dry clutches is pretty much non-existent. You do want to be sure to use a UTFH that meets JDM J20C specs if you choose not to run JD Hy Gard. The wrong oil can cause problems. Do you know what the previous owner was running in it?

If you don't have the technical manual, TM1115 and the parts catalog, PC1480, I suggest you get copies and study up on the steering. The wet clutches are applied by oil pressure during normal operation. When a lever is pulled to turn, the oil pressure is dumped from the clutch piston disengaging that clutch. Many have found a slipping clutch was caused by a hose leaking, inside the steering compartment, preventing full pressure from reaching the piston to apply the clutch. If you want all possible parts needed on hand prior to starting; include internal hoses, seals, rings for the clutches and brakes; and the sealing parts for the steering valves. Plan on doing all the system pressure checks and adjustments as diagnostics before teardown, then again after assembly. Inspection after disassembly to determine replacement need is more common in my opinion for the major parts like the pistons. In your case it appears you have ruled that out, so your exposure will be anything that moves, or has a component(s) that move inside it, inside the steering clutch housing. Just my thoughts, YMMV.
