Loosening Bolts

[bluechip]

Tim,
The bolts you are talking about actually carry part of the weight of the tractor. the wheel bearings are in there, the outter one is in the "cover" part and it carries most the weight, the inner bearing is in the main part of that housing, under the cover piece. the 2 parts of the housing are held together by the bolts you mention. As for a mechanical stress causing the bolts to work loose, you might lift the front end of the ground and rotate the wheel, it should turn freely without any binding as it goes around. Be sure you have a little bit of toe in on the front end alignment.

Tim,
If cleaning the holes doesn't fix the problem, take out one bolt out at a time and drill it's head for safety wire. If it is done right, the bolts will never come lose again.

This is a fairly common problem with Jinma 354's too. Rather
than messing around with the factory bolts here I replace them
at initial setup with M12X45 Rockwell 10.9 hex cap screws.
I use LOCKTITE red and torque them to about 60 ft/lbs.
Haven't have a problem since I started doing this.

Cheers
Graham

Thanks everybody for the suggestions!

I won't be able to test any of them until I get some time, probably in 2 weeks. I'll let you guys know what fixed it.
