TC Differential CWP setup

Post by steve c » Tue May 07, 2013 11:25 am

Hi All,
I’m in the final stage of setting up my newly rebuilt TC differential and my questions relate to CWP backlash set-up procedure.
Q1: When adjusting the differential carrier bearing adjuster nuts to just pinch the bearing inner tracks and take up all the slack in the bearings (prior to setting the pre-load) and the locking screw position ends up between two slots, is the correct action to tighten slightly further until the next slot lines up correctly with the locking screw?
Q2: The brown book states it should be the offside nut that is tightened one further serration to set the final pre-load. Other messages I’ve read do not specify a particular side. Should one side take preference in the final tightening for pre-loading?

Any thoughts / answers will be gratefully received.

Regards,

Steve C

Regarding your first question, my understanding is that you are better off backing off the nut to avoid too much preload.

Hi Steve,
Thanks for the reply.
I can see where you are coming from regarding excess pre-load which was my concern.
I've also given this further thought and reckon if one side lines up spot on and the other does not, then backing the good one off one serration and moving the other on a bit further to line up would give a similar result to your reply.
The amount of extra movement required to reach the next serration would dictate which option to chose in order to achieve a near zero initial pre-load before adjusting backlash prior to setting the final pre-load with the final turn of one nut to the next serration..
I'll wait and see if any further info appears here before finishing the job in a few days.
Thanks again.

Regards,

Steve C.
