Oil drive pump with bolts fits Oleo-Mac GSH400 and many other chainsaws. The oil pump is driven off the clutch drum’s worm gear and meters bar and chain oil with every revolution, feeding it out through the oil outlet pipe to lubricate the guide bar and chain; the bolts secure the pump housing to the crankcase. When the pump’s internal plunger or diaphragm wears, or the bolts work loose and let the pump sit misaligned with its drive, oil output drops off or stops altogether, leaving the chain and guide bar running dry and prone to overheating and accelerated wear. Fitting a replacement oil drive pump restores correct oil delivery to the bar and chain.
