420C Steering Clutches

[blackb23]

Hi all,

I just bought a 420 crawler loader... The machine will drive forward and backward just fine. However, it does not turn. So I am getting ready to take it apart to get to the steering clutches.

My question is... when I take the machine apart what would be the assumed minimum parts wise I need to have on hand to replace. I have read too many posts about people just cleaning everything up and putting it back together and the clutches slipping, then having to take it apart again anyway.

So I am assuming I will just buy new fiber and steel clutch discs. Is that enough or should I go ahead and get new brake bands too. I just got the manual from JD.

So I am going to take it all apart soon. But, I don't have a garage so I want to make sure I can get it back together quickly.

I posted pictures of it in show and tell.

As an absolute minimum you should put in fiber discs. If the crawler does not turn, I would assume that the clutches are rusted up. In this case, you should likely put in fibers, steels, throwout bearings and pressure plates. No way to really know on brake bands until you get it apart.
Look real close at the 5 little springs that are in the clutch housing, they are often times broken.

I'm in the camp of - I don't want to do it again.

I'd replace all of the items Lavoy mentions plus the bearings for the axle and pinion shaft and the axle seals.
