Why did I break a belt and how can I stop it from happening again?

Continued.........

We mentioned in our last Blog that back in 2006 or so, a broken belt turned into another performance part the buggy world needed. Here's how that happened.............................

There was only one choice for a new clutch for our CN250 back then as this sport was in its infancy, and that was from DRPulley. They had just came out with a new clutch (The HIT clutch) and were offering a discount on the first 5 folks who were willing to test it in a buggy for them. Unfortunately, we did not make the "Fab 5" but didn't let that stop us from buying one a few weeks later.

Before installing the new clutch, we were trying to figure out why, a nearly new belt broke, which led to also needing to figure out how the CVT system worked. Once we knew that, we realized that we were breaking belts because we were doing a lot of hill climbing and we didn't get off the gas when the rear wheels stopped moving so the front pulley is going 10,000rpm's but the rear pulley was going zero! Not rocket science now!

Rather than "getting off the gas", we decided to see if we could actually make the CVT work better. Maybe lighten up the transmission somehow so there's less stress on the motor and more power gets to the wheels, so we weren't petering out at the top of some of the hills around here in PA.

Our first thought (Because we just happened to be having a problem with a brand new, $300 clutch from DRPulley), was to play with the clutch. We had one that was useless to us and since it cost so much and neither the dealer nor the MFG would stand behind a clutch missing an arm pad!, we took our dremmel to it and tried to find a way to attach the pad back on. We didn't figure how to do that but upon further inspection of the clutch while it was all apart, led to some ideas. A few days later, we had our first prototype Shorty clutch and our first test, we did a 360 burnout, coming out of the garage! We figured it out it seems until....

Stay tuned next week for...
