Thanks much Greg…
wow! That was a bit scary of an incident…glad it wasn’t worse.
When this first started giving trouble, the original belt (I’m second owner) smoked some on a hilly driveway, and stalled. I was able to limp it up to the garage and then dig into it…
Ordered a new “Kevlar” belt and installed after cleaning out the case (it was a real mess!) A couple of test trips up and down the driveway, and bam! that belt ripped to shreds. I put the original back on it just for testing, along with the new front variator pulley. And another cleaning of the case. Immediately it started the jerking/grabbing at low speeds. (I’m sure the original belt idea wasn’t smart but it was a learning thing) And again, this last time tearing into it found the case again in dirty position, with the buildup on both pulleys…
thanks again for your insight.
