Bought a new 25" ES Rollomatic bar and a loop of RSK chain for my MS440 this morning thinking it would help solve the problem, no such luck. I can be cooking wide open through a log and the nose sprocket will just lock up solid with chips, particularly when doing felling cuts (sideways). Doesn't happen in soft wood, just oak and hickory and with a 28" bar its more frequent. I even had one link taken out of a 28" chain so that I could barely get in on, thinking the almost maxxed out adjustment was allowing chips under the chain, didn't help. Loose chain makes it worse but even when fiddle string tight it still happens. I don't think I've ever jammed the sprocket on my 029 with a 20" standard E bar so I'm pretty sure its the machine and not the operator.
I bought the 440 used with the PNW clutch cover and the rubber chip deflector is a little chewed up for some reason. Could this be the problem? All my chains are RSK, are they prone to this? Any other ideas please?
