Review on OEM 503660102 Oil Pump Plunger Piston For Husqvarna 50, 51, 55 & 55 Rancher Chainsaws (505317216 EPA) by Mike Betzing

I recently purchased the OEM 503660102 Oil Pump Plunger Piston for my Husqvarna 55 Rancher and have some mixed feelings about it. On the one hand, it does an adequate job of pumping oil to the chain, which is obviously important for the health and longevity of the saw. On the other hand, it doesn't really give me that "oomph" I was hoping for. It's like the plunger piston is just phoning it in, doing the bare minimum to get by. Overall, I would give this product three stars. It gets the job done, but there's nothing particularly impressive about it. If you're in a pinch and need a new plunger piston, go ahead and give it a shot. But if you're looking for something that will truly knock your socks off (or, you know, lubricate your chain with gusto), you might want to keep searching.
