Thanks fellas for the info thus far. I just started rebuilding a four roler 40c and it has two diferent rolers on it. Which is the correct one? Do you notice how the one on the left is thicker and heavier duty ?thanks

The one on the left is a good roller with little wear. The one on the right is very worn. It's basically the same roller at two different stages of life. You want rollers that look like the left one. There were minor variations in the roller shells over the years but the same basic profile was used from the earliest crawlers right down through the 350. The dimensions of a new roller are on the jdparts.com site for a 350 roller.
Lavoy, correct me if I'm wrong but I've got a bunch of worn rollers here and you can see the wear progression across the samples that I have.

greasing rollers
My new to me 2010 has some rollers with grease fittings and some without. What is the significance? Also there are tie bolts down there that all seem to be loose, how important are they?

I think the rollers without a grease fitting are aftermarket sealed rollers that do not require additional lubrication.robvds wrote:My new to me 2010 has some rollers with grease fittings and some without.

I am not sure what you mean by tie bolts- are you referring to the roller to trackframe bolts?

The two pieces that go on either end of the roller are called brackets in the parts book. The shaft has a dimple drilled on the side of both ends that the setscrew engages. The dimples are aligned with one another so if you use two setscrews, they would only line up with one of the two dimples as they are at opposite angles with the brackets facing each other.
Most of my rollers had setscrews in both ends but the exploded diagram of the roller group shows only one setscrew and locknut used on the same side as the grease fitting. The inside setscrew can't really grip as it is being screwed against the side of a hardened steel shaft.
