JD 350 front idler wear

Post by kwtownsend » Thu Jul 23, 2009 5:22 pm

Hi-

First time poster...

How thick should the "flange" be on the front idler on a John Deere 350 crawler? I know there is a measuring gauge for this... On mine the edges that the track runs along are less than 1/4" and there are chunks broken out. I think they may need to be replaced. How thick should those edges be?

It is a 1967 JD350
Thanks

-Keith

5/16"-3/8" of the top of my head, but don't bet the farm on it. Once they have started to chip, they seem to just keep going.

Lavoy, are the front idlers the same for a 350 as for a 2010? If so, I can measure the NOS front idlers you just shipped me. Just a thought.

Yes, although if they are chipping, they might be getting awful thin.
