Case450B track pad bolts spinning

[Case450]

How the heck do i keep the track pad nuts from spinning when trying to tighten a few loose track pad bolts? I can't get a 3/4 inch wrench inside the track chain onto the nuts, i tried a large crescent wrench.....actually maybe a shim might work....maybe i'll jam a shim in between the track pad nut and the track chain link that should keep it from spinning. Sorry.

drive a wedge in between nut and link and try an impact . good luck you will probably need to cut the nuts off and put new bolts in them.

Second what Red said, get new bolts and nuts,, normally have to cut the old ones as they are designed to stay tight, they are special bolts very tough,, if the holes in the pads are slopped out they need fixed before the new bolts are installed, as well as making sure the contact points on chain and pads are clean from rust/paint ect never had any luck on getting old ones loose in the smaller crawlers,, I just fixed a pad that was loose on my 450 , the bolts are not cheap but are what you need in them
