K&B parts

[Gary Lauer]

I recently bought a bunch of vintage rc boat stuff. there is a box of used K&B 21 parts. Also some new parts. I need to know how to idenitfy the crankshafts. Some have numbers, a letter L and plain. I dont know which goes with whitch engine. Any help would be appreceated. Thanks

The L is a 12mm diameter shaft, the 13 is a 13mm shaft. one without an L or 13 is an inboard shaft. The bearing in the front plate will be the determining factor. The front plate and bearing will tell all.
