SEGMENT DESCRIPTION WHEN TO USE
The standard 90° segment provides a very good balance of performance
between on- and off-power. On-power the diff becomes hard after a
brief delay. Off-power the diff becomes free after a brief delay.
Suggested to use for high grip
and/or bumpy track.
The optional 120° segment gives more immediate response both on-
and off-power. On-power the diff becomes very hard immediately (no
delay). Off-power the diff becomes free immediately (no delay).
Suggested to use for slippery
and/or flat track.

In the event that the diff has too tight or too loose gear mesh between the diff spur gear and the pinion drive gear, this is easily resolved by inserting 1 or 2 thin shims behind a
diff outdrive ball-bearing, depending on how much play there is.
GEAR MESH ADJUSTMENT
THE LOCATION OF THE SHIM(S) DEPENDS ON WHETHER YOU ARE TRYING TO CLOSE OR OPEN THE GAP.
To close a wide gap:
add 1 or 2 shims against diff spur gear

TO OPEN A NARROW GAP

After assembly the differential should have
a length of 32.15~32.30mm measured
from the ends of the installed ball-bearings.
If differentials are longer, retighten the 4
screws holding the crown gear.
Tight the screws equally Finish tightening in this order
