Well another exciting Saturday night so I decided to have my 13 year old learn how to maintain the chain case on the 1983 Polars Indy 440 his uncle gave him. He got the pipe off, removed the bolts and popped the cover. Almost no oil came out and he had some questions. What was the orange gunc on the gasket and globbed on the walls of the chain case. I have never seen anyone seal a case with liquid gasket over a perfectly good seal. He sprayed things down with brake cleaner and mopped up the case. Then he backed off the chain tension and took off the chain, looks like new, not 1983. Looking at the gears they are nice too, but near the lower gear the chain case cover has some nasty scratching and gouging and there was some scratching on the case side. I am guesing that maybe an old chain got loose and did this? , well ask Unc as he bought this sled new. Any way has anyone heard of using liquid gasket on these old sleds? Think we should worry about the scratching, sled sure runs good.
