262 clutch 3/8 vs .325

[Gwiz]

Finally finishing a rebuild 261 conversion to 262. Ready to start it and the chain would not roll. Previous owner had been running a .325 bar and chain with a 3/8 rim gear.
I picked up a .325 rim today not realizing I also needed a clutch drum.
Can I now just buy the .325 drum and use my old bearing, or is something else not going to fit?
Thanks
James

What was wrong with your drum? I think on that saw I would run 3/8".

Nothing wrong with drum. I just had a .325 bar and chain.
The .325 rim gear won't fit on the 3/8 drum.

You need the right size rim for the drum, small spline or large spline. Believe that saw takes large. You can use either .325 or 3/8. I'd run 3/8 on it.

I did some searching here and see 3/8 recommended repeatedly. Guess I will get a different bar and chain. Thanks.

You can only run 9 pin 325 on that saw as It takes a large spline rim. If your rim has less teeth, it's the wrong one. A new drum won't fix it. You need the right rim. Oregon sd7 3/8 7 tooth is part# 68210. 9 tooth 325 is part #13624 for you drum. The larger 9 tooth gear often necessitates an extra drive link in the chain.

I understand that over here those saws came with a small 7-spline drum and .325 - but would not be surpriced if the US ones came with 3/8x7.
Different 3/8"x7 rims are made for both small and standard (large) 7-spline drums, but the Husky 60cc saws that come with 3/8 had/has the standard 7-spline drum, that won't take a .325x7 or x8 rim.

This also was the case on the 262xp.

If you can find one, you can find a small spline drum. I just did this so I can use shorter bars from my 55. You may have to also change the worm gear out for the oil pump. Oregon doesn't make them any more but I was able to get old stock a couple weeks ago. If you use the large spline with a 9 pin you will have to add links. I post the oregon number when get home later if that helps.

You need a new rim as well, as the use of .325 on a 3/8" rim will have damaged it.

The small spline Oregon Part #
40071x type p old # 100758 and you can use 7 & 8 pin .325, or a 7 pin 3/8 an not have to add any links to the chain in my experience.
