The pig was just freshened with new bearings & pinion seal last fall. I re-installed the yolk and torqued it to 190 lbs. I was told by the person who re-built my pig that he torqued it to 225 ft. lbs. The yolk definately felt different(tighter)after I torqued to 190 I was gonna step it to 225lbs after I reached 190 but stopped because it felt tighter. The next day after driving it to the track,it broke on the starting line after 1 easy pass to break in the new slicks. Do you think I probably crushed the sleeve further,and changed the pre-load? John
if it felt tighter then yes you over torqued it and that is why it broke ...
But I have to ask why ANYONE still uses a crush sleeve ??? It's an accident waiting to happen, solid spacers have been available for the 489 for close to 20 years ...
