Mornin' Guys, Got one for ya and wanna see what you fellas think. On this old NH 849 baler that I bought, the old gal is just in pretty darned good shape and bales hay like a monster 'except' it has quite a bit of chain noise coming from where the round machine bolt heads on the big chain cross bars make contact with those two big rubber rollers. Over the years and with normal wear, the action of those bolt heads have worn the rubber material away from the drums on both sides and have left a "track" on each side of the drums, so that the bolt heads now ride down on the rollers' metal core. This, in turn, sets up a "clickity, clackity" noise every time a chain bar comes around the drum. Naturally, I don't want to buy those two big rubber rollers and was wondering if there was some kind of a "spray on" rubber coating that I could "fill" those tracks back in with? Kind of a 'spray on rubber' material? I know, it sounds crazy, but I'm old, plus I'm kinda picky and can remember the balers sure didn't make that noise when they were new. The prior owner has already made all the expensive repairs of replacing the chain, the bars and the bolts and if I could just shut that chain noise up, the baler would really be a sweet old unit. Thanks, Allan
