CT235 Differential bolts question

[jrpat]

I have a 2009 CT235 that I have a reoccurring problem with. The bolts that connect the transmission and differential keep loosening up. About 4 times a year (depending on my use) I have to pull the seat and retighten the bolts (and 2 nuts on the pilot studs). I have loctited the bolts 2 times. The 2nd time I sprayed Brakleen into the hole then blew the hole out with my air compressor before applying the Loctite. I have purchased a primer made by Loctite that I'm using next time. Has anyone had the same problem? Does anyone know the torque specs on theses bolts? They are only a 3/8 inch bolt (9/16 head on the bolt). Thanks in advance J R Patton

Bobcat had issues with that problem. Its not the bolts loosening up but the bolts stretching under torque.Contact your dealer. There is a service bulletin for that problem. They will be able to get you the replacement hardware which is the solution to your problem. I'm surprised your tractor is not leaking.:thumbsup:

This is not very comforting to hear.

The issue was with early production models. If your tractor is not leaking yet it was updated or a later model.:thumbsup:

Went out and looked at mine after your post. I don't see any looseness in the seam. However, I have been told mine is a 2008 year model.

Your unit may have already been updated. Look for the thicker heaver washers on the bolts. These tractors will leak if you have loose hardware. Do you have a FEL on it?

Looks like a normal washer but not sure. I checked every bolt and nothing loose and nothing leaking. Yes, I do have a loader. I'll have to think it has been put through the testing process with 1511 hours so if not leaking and not loose now things ought to be ok. Thanks for your concern and suggestions.

I've talked to my dealer 2 or 3 times. Looks like tomorrow will be the 4th time! I'll try and get bolts and lock washers too. It doesn't leak when the bolts are tight. I do have a front end loader. Thanks for the info. JP

Ask your dealer to print out"Knowledge article" #000002611 for you. It explains the problem and gives you the PT#s.

Thanks so much. I'm just waiting for them to open up to call them. Thanks again. JP
