The parts from eReplacements were very useful

The parts were used to repair the oil leak on a Husqvarna 440e chainsaw. These saws are notorious for their oil leaks. Your parts arrived quickly and were very useful. I highly recommend your services.

Thanks

The oiler wouldn’t oil the bar anymore because I used to use canola oil and I think it hardened inside the piston.

I removed the bar and chain. Then popped the cover off the top of the saw removed the spark plug and put in this special piston stopper I got when I converted my saw to a chain saw carving saw. Then I put some vise grips clamped to the clutch used another wrench to turn the clutch till it came off. Removed the clutch and all the other inner. Then removed the metal shield plate and got access to the piston and pump and oil tube thingy. Swapped all that out cleaned the old oil bar oil off and put it all back together the way I took it apart.
