meadowfield 2,545 #1 Posted February 23, 2015 I've a Magnum M16S on my latest project which came from a Toro Reelmaster mower. I bought a standard 4" pulley from another Wheel Horse on that auction site. When I came to attach it - the crankshaft is 1" diameter and the pulley is 1-1/8" Do I have a rogue engine or Pulley?

pfrederi 17,169 #2 Posted February 23, 2015 Kohler used different crankshafts based on the customers requirements. Look for a pulley from an 8hp Wheel Horse they had 1" bores. you will also need the sleeve from it if you are planning on having a manual PTO. Share this post Link to post Share on other sites
shallowwatersailor 3,213 #3 Posted February 23, 2015 Just find a sleeve adapter to increase the shaft size from 1" to 1-1/8". They are on eBay all the time. Share this post Link to post Share on other sites

I think the horizontal shaft B&S engines also used 1" cranks. Garry Share this post Link to post Share on other sites
