Is your big Stihl 066 or MS660 chainsaw (or its Holzfforma G660 clone) not oiling the chain properly? The automatic oil pump might be worn out. This is a brand new replacement pump from The Duke's Saw Salvage, part number I-62 MS660OILPUMP. It's designed for the 2-stroke gasoline engines on these powerful saws and should also fit models that use the 1122 series crankcase. Replacing a faulty pump restores the vital flow of bar and chain oil, preventing excessive wear, overheating, and dangerous kickbacks. It's a critical maintenance part for anyone who uses their saw for logging, milling, or heavy firewood cutting. Installation requires some mechanical know-how. Keep your saw running cool and cutting smoothly. Don't let a cheap pump ruin an expensive bar and chain—or your day. Get your saw's lubrication system back in action.
