Husqvarna 570 clutch

[Jasonrkba]

I'm having some problems putting this saw back together. The oil pump worm gear has a bushing or spacer that it spins on. The clutch when installed sandwiches the worm gear and spacer. Almost like the crank is not sticking out fat enough. I've had the case apart a couple times and everything is together good.

Any suggestions are appreciated.
Thanks. Jason.

Adding a picture of the clutch. I have tried both sides of it.

Anyone? Lot's of folks smarter than me in here.

@huskihl maybe

I looked at IPL and nothing missing. Hope he has idea. I have owned 570 and worked on 575 576 and never issue like that.


Do know I told this guy toss this clutch drum style on his 576.

It could be from the vents. Or just lack of maintenance. I’ve never seen a difference in how a 365 looked underneath the vented drum than what a 372 looks like.

Drum is not an issue. The clutch when tightened sandwiches the worm gear against the oil pump.

Is the crank properly centered?

That was my initial thought. I popped it with a dead blow like usual after the case halves where assembled. This is the third time the case has been split and put back together. Everything spins freely. I've tried lightly but sternly if that makes sense with a dead blow hitting the crank also using deep socket on the case around the bearing. I also stacked washers around the crank on top of the bearing, socket and dead blow. It feels like one more revolution and the clutch will bottom out so its close. I gapped the distance between the cam lobes and case and they are the same. Im at at a loss.

Thanks. Jason.
