2) SPLINE NO-SPIN ASM (#20) UNTO GEAR (#2).
3) INSTALL RETAINER (#16).
4) INSTALL CAPSCREWS WITH LOCTITE #262 & TORQUE TO 27 LBS. FT. PER S.I.M. 765.
5) REMOVE WASHERS & BOLT HOLDING NO-SPIN ASM. (#20) TOGETHER, LETTING SPRINGS PUSH RETAINERS OUT
AGAINST BEARING CUPS (#19).
6) INSTALL TROUGH (#10) INTO MAIN HOUSING WITH CAPSCREWS (#11) & WASHERS (#12) APPLY LOCTITE #262 UNDER
HEAD OF CAPSCREWS.
7) PLACE NO-SPIN GEAR ASM. INTO TROUGH LOCATED IN MAIN HOUSING.
8) INSTALL BEARINGS (#3-2 & #3-3) INTO SHAFT (#3-1). INSTALL SPRING RETAINER (#15) & BEARING CONES (#18 & #21)
ON SHAFT (#3-1). INSTALL THIS SHAFT ASSEMBLY THROUGH ENGINE SIDE OUTPUT BORE INTO NO-SPIN ASM.
9) INSTALL BEARING CUP (#22). OIL SEAL (#7) & O-RING (#8) INTO BEARING RETAINER (#6) & INSTALL THIS ASM. INTO
ENGINE SIDE OUTPUT BORE. THEN INSTALL RETAINER CAPSCREWS (#9).
10) INSTALL SPRING RETAINER (#15) & BEARING CONES (#18 & #4) ONTO SHAFT (#1) & INSTALL THIS ASM. THROUGH OPPOSITE ENGINE

NOT INSTALL O-RING AT THIS TIME.
12) INSTALL OPPOSITE ENGINE SIDE BEARING RETAINER ONTO TRANSMISSION WITH TWO CAPSCREWS (OMIT ‘O-RING”).
13) PUSH RETAINER INWARD & TIGHTEN CAPSCREWS FINGER TIGHT.
14) TO SEAT ALL COMPONENTS TIGHTEN EACH CAPSCREW TO 175 IN. LB. IN (3) EVEN STEPS. (50, 125, & 175 IN. LB.) ROTATE SHAFT AT
EACH STEP, THEN LOOSEN BOTH CAPSCREWS BACK DOWN TO FINGER TIGHT.
15) LOCK-UP OUTPUT GEAR WITH FIXTURE TO PREVENT ROTATION.
16) TIGHTEN EACH CAPSCREW TO 50 IN. LB. & ROTATE EACH OUPUT SHAFT.
17) TIGHTEN EACH CAPSCREW TO 100 IN. LB. & ROTATE EACH OUTPUT SHAFT.
18) MEASURE THE SHIM GAP WITH TAPER GAGE AT EACH CAPSCREW LOCATION. (PLACE EDGE OF TAPER GAGE ON CAPSCREW FOR A
GUIDE).
19) MAKE AN AVERAGE OF THE TWO READINGS. EXAMPLE: .040” + .047” = (0.87/2)=.0435”.
20) ADD .018” TO THE SHIM GAP FOUND IN STEP #18.
21) INSTALL “O” RING ON RETAINER. APPLY CORRECT SHIM PACK (FROM STEP #19) & TORQUE CAPSCREWS.
22) CHECK BEARING SETTING WITH DIAL INDICATOR. SHOULD BE IN RANGE OF .0025” PRE-LOAD TO .0025” EBD-PLAY.
23) INSTALL EXPANSION & CUP PLUGS (#13 & 14) USING LOCTITE #262 IB O.D. OF PLUGS.

ROTATE BOTH OUTPUT SHAFTS. WITH THE OUTPUT GEAR HELD STATIONARY IT SHOULD REQUIRE FROM 15 TO 80 LBS FT OF TORQUE TO
BREAK EACH SHAFT LOOSE.
IF IT TAKES MORE OR LESS TORQUE THAN LISTED, THERE IS SOMETHING ASSEMBLED INCORRECTLY OR OUT OF SPEC PARTS.
