Bolt Size on 79cc Predator Crankshaft

[JohnnyReb]

I bought 8mm x 1.0 and it does not fit. I bought 5/16" x 24 and it fits but my mechanic says it is the wrong . What size is it? Maybe a 8mm x 1.25????? Help!!!!

Try an 8mm/1.25. It looks just like a 5/16x24, but the threads are different.

 

[JohnnyReb]

I will try but the 5/16"x24 fits perfectly.

If it fits perfectly, then use it. That is same size and thread count as used on the 212 & 224.

Understood.

The mechanic was just speaking from what he's experienced.

Glad you were paying close attention to your particular scenario.

It confuses A lot of people, being that the engine is manufactured in China, and the majority of fasteners and measurements are metric. Then when you go to bolt on a clutch or even a torque converter, the holes are tapped in standard American sizes. Go figure. Lots of stripped side covers out there from people forcing in the metric bolts that come with the torque converters.
