I run a TZ and maxload and dont have straight cuts , I cant see why a better bearing would make any differance . Quote Link to comment Share on other sites More sharing options...

Wildcardracing Posted April 25, 2012 Report Share Posted April 25, 2012 The problem found is when you run the tz on the pto side without straight cuts. TZ beaings are a roller type bearing and therefore have no resistance to side loading. Your stock helical cut gears side load the crank when you're on the throtte. This can/will exert more force on the rod pin area as the crank is loaded. My recommendation is to run the 10 ball Maxloads with stock gears or a TZ on the stator side not the PTO side. -Brandon Quote Link to comment Share on other sites More sharing options...
zach45 Posted April 25, 2012 Author Report Share Posted April 25, 2012 I should be fine with 2 max load barring anyhow... Thanks Quote Link to comment Share on other sites More sharing options...
