I have a very good Cat40 bolt to bench for installing tools but it is a nasty
job to bolt the cat40 back into the spindle.
If I could get access I’d pull the whole mess and replace (ideally). The stack
is 105 washers so not too expensive. I’ll climb up on top and take another good
look down
The mining industry uses these washer stacks to secure replaceable wear
plates in Jaw crushers. Twist the nut down until the compressed washers
all fit into a “cup” and viola bolt is torqued and the bolt has additional
springiness beyond just the steel of the bolt
I would agree with Todd
