I think I,m the guy that pressed the gear on,,, I did, It came apart in about five minutes of the engines first start up,,when got the new gear set,(cloyes), it was in a different style box, in the box was a red paper instructing you not under any circumstance to press the gear on,,, I called to see if I could get a refund because the older(previous) box had no such literature,no refund, but they did say the hardening of the cam, shears material off the gear while pressing, causing the failures,,I froze and baked,, the gear went on with my hands, no pressing needed, for a street/mild engine this was supposed to be ok,, It has been so far,, about 3 years,,,, c-ya
