hi guys whats the size of the nut on the 2 stroke engines rotary 2 on the fly wheel under neath the motor oon a 160 2 stroke graham gsau22@yahoo.com.au

1/2" BSF 16 is the old size, but I only know mowers up until the mid 60's. Id like confirmation as to if and when they changed.

Either the ODK online store might have a listing, or your mower shop should know.

Its not a size youd find at The hardware or even specialty fastener shops in single form or on the shelf.

On the full crankshaft 160cc engines, as Blue says, that's the thread size. The nut hex size is 1" AF/SAE, on those 160's.

The half-crank Powertorque engine uses ISO Metric threads, and the corresponding nut hex sizes. For that nut, the thread is 14mm, but dunno what pitch or exact hex size - it will be one of the common metric hexes though.

But I haven't worked on a Powertorque, and have no particular desire to do so!

Thankyou Gadge.

I was Sure all 125 and 160 full cranks used this size,but wanted confirmation:)

Not sure on the pitch on the powertorque but the hex size is 24mm
