Reminds me of 45 years ago when I was a safety-wire plier machine. We used those on virtually all bolts working on reciprocating and turbine aircraft. They do their job well. I know that in aircraft they can be life or death issues vs riding a JD 2305 tractor are different. That said, I'd spend the few extra bucks and apply those to help mitigate potential bills of $1,500 plus.There was no lock-tite on those bolts, and the bolt heads are not drilled for safety wire. No wonder they came loose.
I just checked the 1025R Technical Manual to see if JD indicates whether the ring gear attaching bolts are supposed to have thread locker applied to the attaching bolts. They do indicate to apply thread locker.
Hopefully they did when they initially installed them. :dunno:
I personally believe cap-screws that are used in these types of applications should be safety-wire bolts, but I guess they are just too expensive and take too much time to install!!!
OP: You've done a fantastic job of helping others here on GTT :yahoo:
