Husky 357 oil drive issues

[DB2K]

So, my boss and I have been trying to rebuild a husky 357 that was had been stripped of its clutch, sprocket and the little plastic oil drive thing. Initially we got a 3/8 clutch drum, and all the rest. Eventually realising we'd made a cock up asthe saw didn't have the right mounts for the larger bar. We then got a .325 drum, sprocket and oil drive and the oil drive sprocket didn't fit on the driveshaft. So we ordered a different oil drive sprocket. And that didn't fit on the driveshaft. Finally we tried another. 325 sprocket and it all fitted together great. Then literally the first time the saw was revved up after assembly the part of the oil drive sprocket that interlocks with the clutch drum basically disintegrated. So still not working. 

Can anyone suggest an oil drive sprocket that might fit and do the job it was intended for?

You can run 3/8 or .325 . You need 3/8 small spline and you need the plastic oil pump ,drive for 3/8 small spline . If you run .325 you need the oil drive that fits that .

Thanks. 

All 3 of the .325 pump pinions we've ordered have been sold as 357 pump pinions but only 1 has actually fitted onto the main driveshaft. On all 3 the interface between the pinion and clutch drum is the correct shape it's the diameter of the hole in the pinion that had been causing the issue. Then we got one that fitted and promptly disintegrated. 

Seems the best bet is using the part number in the and getting an official factory part.

All the 3/8 clutch bits went on perfectly. The bar was the issue

 It's a new 3/8 18'' Husky XForce bar but it didn't fit the bar mount on the saw.

Aftermarket bits are sometimes a crapshoot, OEM oil pump drives are recommended

The 357xp only came as standard with small bar pad and .325 sprocket, rim and pump drive gear, the crank journal never never changed diameter.
