350 Track/front idler adjustment

Post by jbloam » Tue Mar 12, 2019 4:27 pm

Can anybody tell me a part number for the track/front idler adjustment shims installed between the idler bracket and hydraulic track adjuster tube on a straight 350. I think it might be T10022 listed as a "strap", but i want to be sure. Thanks.

As I read the parts catalog the hydraulic adjuster didn't use the shims (straps). None are shown with the hydraulic adjuster or idler brackets, but things get missed sometimes. The part number you have is for the manual adjusters. Again, from the parts catalog, it appears they used the same idler brackets with both adjusters so, it is likely those will fit.

Thanks Jim, I replaced the seals on my hydraulic adjusters and there was only 1 shim on each side of the tube. Extremely rusted, almost right through. Reading previous posts I assume there are supposed to be numerous shims stacked on each side. The center flange on my front idlers are worn on the outside flange much more than the inside flange. The chain is rubbing on the outside flange and it's about 1/4" to 5/16" away from the inside flange. I assume I need to re shim everything

Check trackframes for square and parallel as well.

Thanks Lavoy, I was reading a post from 2009 where you were giving instructions on how to do this on a 440. I made the assumption I will do it in the same manner. Great site by the way!

Glad you like it.
Not to say you still don't need idler adjustment, but I find trackframe alignment is usually the culprit.
