Bench Testing engines

Recommended Posts

wasmeneh
I'm getting ready to put new rings on my Kohler engine out of my AC 714 H. I've got Sam's old engine in the tractor now. I'd like to bench test the K321 to see if the rings solve my problem, any hints how to do it safely. I plan to bolt the engine to my bench and I have a small gas tank I can use, but how does the electrical hook up go? Thanks Mike

Hook ground to the engine block. Hook positive to the positive side of the coil to energize the ignition. Then jump positive to the large connection on the starter to turn the engine. I usually clamp a piece of smaller wire in the end of the jumper cables to hook up the ignition, and then touch the positive cable clamp directly to the starter connection to spin the starter. Hope this was understandable. I ran a K321 that I have with it just sitting in the floor of my garage. It was not even bolted down. Doesn't move much.
