Small Engines (Lawn Mowers, etc.)/crankshaft pulley


I have a new 205 cc Briggs engine with 6:1 gear reduction. I am replacing the older engine on my two wheel tractor. My question is about the crank shaft pulley. The crank shaft pulley that came off he old engine fits the new shaft fine, however it strikes the gear reduction housing lightly. Would it be ok to put a washer behind the pulley as a spacer, to keep the pulley from striking?

A washer should not be a problem but will the washer cause a mis-alignement with driven parts such as a belt or chain?   I am betting the slight mis-alignement will not be a problem.

You could also cut or grind the pulley shaft just a little to keep the pulley from rubbing the gear reduction.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
