Hard parts for golf carts are one of the things that will always keep us in business. The accessories are great, but the OEM parts that actually hold the golf cart together and allow it to run will always be in demand. Some of which are harder to find than others. Due to their popularity or age, some of these items can be near impossible to come across. The Yamaha Piston Pin Clip is one of those pats that, without it, your golf cart can't even move.The piston attaches to the connecting rod with a pin that rides in a groove on the end of the rod. That pin is held in place by the Yamaha piston pin clip. Without this part, the piston would come loose from the rod, and you would lose all of your compression. Once that happens, you are dead in the water. So get on the phone and call Buggies Unlimited for a few replacements before you are stuck.
