    Sprag/one way bearing?

    Hey guys, I have to change the one way bearing in my new SX. Does anyone have a pic of a bad one vs. a good one? Is a bad one easy enough to spot? I have 3 BR engines and one SX engine on the shelf, and I sure don't want to put another bad one in... and I don't want to buy new. Any help?

    It should grab in one direction and freewheel in the other. If there is any play in it driving/grabbing, it's junk. Sometimes the journal it rides on is worn out; Must be a spec for that in the manual.

    Yep,,,You will not per say " See" wear on the rollers.. You will need to replace the journal for things to be right. I assume we're in the flywheel? Same for either side.

    Ohh,,ok,,So,we're in the clutch.. I will be willing to bet a lot the starter clutch is also shot. This all means he didn't change oil.. Flush that engine out really good with your choice of flush. Mine being gas Diesel won't cut anywhere near as good,but makes some feel more comfortable..
