FRONT & REAR DIFFERENTIAL

1

1. 

Hold the diff shaft with the installed pulley facing up. Place the other

#309020 (BB 5x8) ball-bearing on the center stub on top of the other bearing.

2

2..

Put a very thin coat of grease on the side of a diff washer, and place it on

the long diff shaft. The washer should seat centered on the diff shaft, and the
layer of grease will hold it in place.

3..

Insert the diff screw into the long diff shaft and place a small Allen wrench

through both pieces where the hole lines up. The end of the diff screw should
extend about 8mm from the center of the diff shaft.

4..

Lower the long diff shaft with the screw pointing down onto the short shaft

with the pulley. Carefully thread the diff screw into the center of the short diff
shaft. Keep tightening until the diff washer just touches the diff balls.

Place another wrench in the slot of the short diff shaft.

Cover each of the diff halves with the Labyrinth Dust Covers. The
covers fit precisely and should "snap" into place. Once snapped on,
the covers will seat perfectly.

Tighten the diff until you feel some resistance. To check the diff,
hold both wrenches in one hand and try to move the pulley with
the other. It should take some force to get the pulley to slip
between the two outdrives. Then remove both wrenches and rotate
one of the diff halves while holding the pulley stationery. The
action should feel smooth. If it doesn't, loosen the diff screw 1/16
to 1/8 of a turn. Final adjustment will be made with the diff in the
car and on the track.

meerr:: When you build the differential, do not tighten it fully,

the differential needs to break-in. That means that you should
build the diff and tighten very gently. Afterwards you put it in the
car, run the car for few minutes and tighten little bit the diff, make
the same steps several times after you will have the diff completely
tightened.

When you need to open the differential, use the shaft of a wrench to
spread the dust covers apart to pop them off.

Please note the way that the

cone washers need to face

each other.

DO NOT TIGHTEN THE DIFF COMPLETELY !
THE DIFF MUST BE BREAK-IN !
