Shuttle shift F/R lever grinding

[Thetylerguy101]

I own a 3510 shuttle. Recently, after the tractor warms up or is at anything higher than idle RPM the forward reverse lever grinds something awful when I shift. Any ideas what this might be? I have used this tractor for years and never heard anything like it.

Your forward reverse synchronizer is failing.

Is this an expensive repair something that I can do easily?

Try adjusting your clutch first. The manual should tell you how.

I forgot to mention that I did try the clutch adjustment from .5 all the way out to about 2.5 and had the same grinding problem no matter the play. Wondering if I unbolt the housing that the lever leads to could there be a fork or something that's out of sync or alignment maybe?

As the first reply indicated. The synchros for the reverser shuttle are worn out.

When the fluid is cold and thick it acts as an additional friction element to the bronze synchronizer rings.

It's NOT an easy task to replace them. Break the tractor, pull the shuttle section down to pieces, replace the synchros (there is no "repairing" them. Then reassemble. It's not rocket surgery, but the parts can be heavy.

Yes, then no. It will not be cheap. You may be able to repair it yourself but I have never seen a synchro replacement procedure that I would call easy.

Thanks. Do you by chance have an idea of cost from a dealer to replace the synchronizers?

 

[RickB]

Dealer labor costs are location dependent and parts costs vary from manufacturer to manufacturer then also from dealer to dealer. Since you don’t list your location and I do not work at a Mahindra dealership what I think your repair might cost is irrelevant. Have a discussion with shops in your area.

Does it grind if you use the clutch? I’m wondering if it’s a pilot bushing and or throw out bearing- this would only apply if it was grinding when the clutch was depressed.
