Professional Chainsaw Oil Pump & Worm Gear Replacement Kit

Keep your chainsaw running at peak performance with this all-inclusive Chainsaw Oil Pump & Worm Gear Kit. Engineered for arborists, loggers, technicians, and homeowners alike, this replacement kit ensures consistent, reliable lubrication so your chainsaw never skips a beat — whether you're felling trees on a remote job site or tackling weekend yard work.

Why Your Chainsaw Needs a Healthy Oil Pump

A properly functioning oil pump is the lifeblood of your chainsaw. Without consistent chain lubrication, friction and heat build up rapidly, accelerating wear on the bar, chain, and drive sprocket. Replacing a failing oil pump and worm gear together — as a matched set — restores factory-level lubrication performance and extends the life of your entire cutting system.
