My 18 year old finally pushed me to get back on a snow machine. I drove Cats in the early '70's in High School. We now picked up a 1997 440 Panther . We have had it out a few times, mainly for ice fishing. It has started easily and runs well but I am facing my first repair job. the overloads both snapped but I am also suspicious of the rear shock. Is there a easily followed replacement procedure for the non-gear head type?
