Will fit ANY motor with a 3/4" shaft and 3/16" keyway
This steel shaft adapter is used to convert a crankshaft from 3/4" to 1" shaft
The adapter is approximately 2.3 inches long and includes the step key needed to go from the 1/4 in key way to the 3/16 key way. This allows you to use your old clutch or pulley on a new engine
You may need to use a small hammer to gently tap it in to place. It is intended to be a tight fit! If it is not tight it will not last. The wider portion of the key sits in the adapter

Adapter shaft size was fine. The key itself failed at some point. Had to get a pry bar and yank the crap out of the adapter sleeve, ruining the gasket on the output shaft of the motor to be able to get a jaw puller set on there (the sleeve is too close to the crankcase to get most jaw pullers on it). The motor had jumped time so luckily it was already ruined. However if that was not the case, it would have junked the motor in replacing.

Adapted a 3/4 inch crankshaft to a 1 inch fan bore hub on a big leaf blower. The sleeve was a very good, zero apparent wobble fit. The key was tight but that's good. The key did not survive the first 2 hours before shearing off, but that protected the engine from a huge potential failure. Taking it all apart again was a huge PITA, and I damaged the sleeve, so am getting another of the same. I hope it lasts longer this time around.

Its working. Will update review if any issues. The key seems it could be a bit thicker
