Hi,
There is a rod bearing who is NLA to my Husky 133SG project
Dimension is 10×13×10.

I would like to know if this needle bearing is possible to get from a quality AM brand. China bearings is not one options.

I don't think you want to use a clutch drum bearing in a connecting rod application. They're usually constructed differently. Clutch drum needle bearings usually have a plastic or phenolic cage which will quickly break down if used in an engine.

thanks, never thought about that, so then the Stihl drum bearing is out.
I've checked ebay, only china bearing there :(

You can probably use the needle cage for the connecting rod out of a MS-260. It is 10x13x12.5 (12.5mm wide, which isn't ideal but will not affect the running of your 133).

It is part number 9512 003 2252. You can see if your dealer has one in stock and then take a look at it. Maybe even take your 133 bottom end with you and do a comparison right on the connecting rod. It may be possible to widen the wrist pin bosses in your 133 piston enough.

I have a box of engine needle bearings at home- I'll measure some tonight and see if I have one that meets your dimensions.
