Good Morning,

My question how to tell if i should replace the steel separator discs? I might not be understanding the Service manual but im reading it as long as they are not pitted or thrashed they should be okay? However if its better to just replace since im in there rather then take a part in the future then i will. I can add pictures if that would be helpful. 

Thanks as always.

I know on the newer machines we would measure them as there is a spec size and re use if a few marks and no deep scratches or heated areas, if some dis colour we would put back in anything outside of these we would go new, generally aftermarket or OEM (if no stock), with older machine I have no idea, im sure someone will chime in to get it correct for you, Cheers

It is a balancing act, between your wallet, and your ambition, amount of expected use.

There is spec for minimum and maximum height of the stack of clutch plates. Cat only talks of adding one extra of each plate. In lean times I have added more old plates. At that point the inner and outer drive teeth become a big part of if the plates are usable. You are not taking a chance of causing more damage if the plates fail. Your just sitting and not turning or moving with any amount power. There are also spec for the springs as well. The only failure of springs I have encountered, they were way less than spec. So kind of surprising it went as far as it did. So if you have more ambition than money you can take some chances on steering clutch plates, that would be foolhardy with bearing or gears.

The other way that the steels can degrade is in the condition of the engaging splines. If yours seem fairly good and snug on the hub, and aren't worn/pitted, then they're reusable. Mine sat in water and were clearly beyond usable so a simple choice to replace them all. That said, with all brand-new components, the steering is like a dream now

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
