Hi everybody! I'm a Land Surveyor, Sawmiller, and general trouble maker, in SW Arkansas. I found this forum, looking for information on a Husky 335XPT oil pump. Whodathunk-of-removing-the-piston-to-change-the-oil-pump? Well, Somebody at STIHL must have skuttled the engineerying at Huskyville, to make that design! Anyway, I have kids that ride unicycles, and often take on hard tasks. Maybe that's why I just finished fixing that husky 335!!!
