Marion,I hope yours is in better shape than Ricks,his has to be one of the most worn ones I've ever seen.I wished we could of fixed it for him but it was wornout beyond repair & we've work on a lot of them.The worst thing is it looks pretty nice on the outside,alot of times the worn ones have all the decals missing & are real dirty.I think who ever ran that machine must of thought it didn't need oil because I doubt if they never oiled it causing the wear. So don't forget to oil every 8-10 hrs use
