Description
Overview:
This genuine Stihl oil pump is an OEM replacement for selected professional petrol chainsaws, including the MS 651 and MS 661. Built with a robust metal-alloy body and precision internal components, it supplies bar and chain oil to the guide bar and chain during cutting. Consistent lubrication reduces friction, heat, and premature wear, helping the saw cut smoothly and protecting key parts under heavy load. The pump is engineered to meet Stihl specifications for fit and performance, making it a dependable fix for poor oiling, intermittent flow, or visible chain dryness. Supplied as the complete pump assembly, it is suitable for workshop repairs and routine maintenance when restoring the saw's original oil delivery. Manufacturer Part Number (MPN): 1144 640 3200.
