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.

Swapped all that out cleaned the old oil bar oil off and put it all back together the way I took it apart.
