Im working on a recent 500 chief i bought, and while cleaning out the belly of the attex i noticed that the rear chains slightly rub on the bottom of the body. They are tight, but seem to just sit on the body. Is this normal or is something wrong. After taking the floor out it looks like it has never been cleaned and must have sat under a tree. I degreesed and pressure washed it out. Looks good and clean now. Going to lube chains and grease joints and such tomorrow. Going to Dune fest in july and would like it ready to go. Any help would be great. thanks all.
