I just bought a T2r Differential, what is the procedure to break-in. Also can anyone explain the science behind the t2r and some specs. thanks.

Hi,

Granted, you asked re Break In for the diff, but here is the Moser procedure for new gears.

Gears (whether they are Ring & Pinon or in the diff) should be similar as to the treatment they like.

Should be a good way to go. I did it to my 12 bolt and have had no problems w/many track miles since. It is relatively quiet too!

M/E Ring & Pinion Gears Break-In Procedure

A new ring and pinon installed with new bearings will initially generate higher than normal operating temperatures. It is advisable to use whichever of the following break-in procedures that matches your application.

Street

1) With car still on jack stands and rear end filled with proper amount of Non-Synthetic lube, run in forward and reverse for approximately 2 to 3 minutes. **
2) Drive vehicle approximately 10 miles at normal operating speed. Accelerate and decelerate several times conservatively, then let cool for one hour.

Drag Racing

1) With car still on jack stands and rear end filled with proper amount of Non-Synthetic lube, run in forward and reverse for approximately 2 to 3 minutes. **
2) Pull to line.

Oval Track

1) With car still on jack stands and rear end filled with proper amount of Non-Synthetic lube, run in forward and reverse for approximately 2 to 3 minutes. **
2) Run several laps at slow to medium speeds; let cool.
3) Run several hot laps; let cool.

**WARNING: OPERATOR MUST REMAIN IN DRIVER'S SEAT AND ALWAYS MAKE SURE FRONT WHEELS ARE BLOCKED AND JACK STANDS ARE SECURED BEFORE ATTEMPTING THIS PROCEDURE - NEVER EXCEED 2000 RPM WITH WHEELS OFF GROUND. FAILURE TO FOLLOW THIS WARNING COULD RESULT IN SERIOUS DAMAGE, PHYSICAL INJURY, OR DEATH.
