Dealer got ahold of me today, cat warrantied the clutches so I'll check my crank run out and If it's still straight I'll be happy. Going to go with an aftermarket shaft though.

You should probably adjust your number using operating machines, people viewing thread is quite irrelevant......

Has the poll author considered the response "No - I have not broke my jackshaft"

I have not broke mine or replaced mine.

Add the third option.......

Running on borrowed time. That's like people that trust the stock silent chain because they haven't broke one.


I am the only one in our group to have broken a chain but I definitely don't trust them! I wonder if everyone who is breaking them is running a stock secondary and the binding or lack of travel in the clutch is trying to flex them and eventually breaking them. We all have aftermarket secondaries except for one 14. And I have done some seriously hard landings with my sled wot on boost, the belt drive and shaft have held up fine.

Mine broke on my 12 at the around the 600 mile mark. I was running a team for around 400 of those miles. Cat did not cover the cost of the team. Installed aftermarket shaft and never had the problem again.
