Replacing a Chainsaw Oil Pump

By Mike attempts | May 24, 2023
Replacing an aftermarket oil pump with a Husqvarna OEM oil pump in a 440 chainsaw. In a previous video, I replaced the cylinder, piston, and a stuck oil pump in this Husqvarna 440. The generic replacement oil pump worked a little too well. Too much bar and chain oil is better than not enough but, when sitting, the saw leaks a lot more than my other Husqvarna saws. See the links below for the parts and tools I used:
