Husqvarna 455 oil pump

I have a 455 Rancher that needs an oil pump for the second time. Have used saw for four years. The first replacement was done by dealer under warranty. I use premium bar oil because dealer said this would prevent lobe from wearing down. Once again it needs to be replaced. Does anyone have a link where I can download a repair manual? Haven't taken it apart yet but suspect it has same problem. Is this a common thing with the 455 or just a fluke?

Not getting any response on this post. Are all the Husqvarna guys on vacation?

Not sure about your answer regarding if this is a common occurance. I was looking for a DIY today, but couldn't find it, but this is what I figured out. You need to buy a metal piston stop, or do what I did and used a longer auto sparkplug with a piece of rag on top of of the piston. With this in place you can use a 1" wrench and another wrench on the first wrench to turn the flywheel clockwise to remove it. Once you do this, remove the one screw that is holding the metal cover in place and the stripped out plastic piece will slide off the shaft and then can be replaced.

Good Luck.
