My old chainsaw had a button you pushed periodically which would squirt oil on the chain bar. Seems like it would be pretty easy to just run hoses to each fitting and have a push button on the dash to push now and then that would squirt a shot of grease into each fitting. If someone could try that and send photos, then I will sign you up for a free 1-Year subscription to Bus Conversion Magazine.
One example of overgreasing would be the brake cams,,very touchy about too much grease, and many others.>>>Dan
Dan there should be a seal to prevent the grease from entering the drum on the S/cam bushing, it has all-ways been you pump grease till you purge the old grease out on the slack adjuster side now if the seal is gone or wore out that is a different story it would be a mess
... they are not supposed to shoot grease 60 feet across the shop.
