Husqvarna 357 XPG clutch drum

[300whisper]

Hello all. Long time lurker and my first post here.

Just got my Husky 357 XPG project finished (complete rebuild). Saw runs nice but when assembling PTO side I noticed way too big side to side play on clutch drum, at least in my opinion. Travel is almost 2 millimeters (~.078” Norte Americano). It may run nice now but after some use worn pinion may stop pumping oil.
I checked my 346 XPG and play there is less than 1 mm. Both saws use same clutch drum, needle bearing and oil pump and pinion (same spare part #).
After some measuring I realized clutch drum bearing surface area on 357 crank is 2 mm wider than in 346. Is there some secret washer to be used on 357 that I’m not aware of? At least I didn’t find any on parts list or parts diagrams.
Your help would be greatly appreciated.
Thank you.

I'll try and remember to have a look this evening.

I went overseas for sport. No room for 357s in my soccer bag.

OP could just swap clutches on his two compatible saws and see what comes of I guess.

Slacker. Yeah, I'd just send it and see what happens. As my old man told me when I was beeching about not being able to find an issue, "Run it till something breaks and then you'll know what was the problem. Or, you may not have any problems show up at all."

This puzzle is solved. 357 XP oil gear (503 91 27- 03) has shoulder and 346 oil gear (503 89 21-03) doesn't.
346 oil gear fits on 357 crank but there is nothing to prevent side to side play.
Confusing enough?

I'll add pics as soon as I have parts in hand.

Edit: pictures as promised. On top is OEM 357 XP oil gear and lower is aftermarket 346 XP.

Glad this got resolved. As noted, the 357/359 have a small or large spline rim and drum, but the oil pump gear has to correspond.
