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.

 

[Thetylerguy101]

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.

If the 3510 clutch assy is the same as my 4110, you could have snapped a pressure plate finger bolt - I have a couple of times over the years. When one snaps it won't release the clutch all the way with the other 2 fingers alone. It will release it just enough to grind it in & out of gear. I've had them snap out in the field and just started it in a low gear and knock it out of gear when you get to where you're going. I tried a clutch rebuilder in Nashville but they couldn't help me with a bolt, had to buy a reman. pressure plate. I've got it down to doing the clutch in one day if all goes smoothly, about a 6 to 8 hour job.

I just had this same problem on my 3510. Sent it to the dealer, and he is telling me it will be over $5000 for this repair. He is offering me a good tradeup to a new tractor. Giving it some thought.

Look for an independent tractor repair shop, and get a price for the labor only in writing.
Parts will cost the same no matter who does the actual work.
Dealers charge outrageous labor prices, and clutch replacement does not require a PHD.

Syncro replacement (which this is suspected to be) is slightly more involved.
I would want to see a breakdown on both quotes of parts vs labor.

If the independent shop lays out $$ at the dealer for parts then marks them up the parts cost to the end user is not the same. The difference may or may not be offset by a more favorable labor rate.
Synchronizer replacement will require a partial transmission teardown, a fair bit more involved than a clutch job.
