engine mount to the frame and
adjust tension bolt to give the belt
slack.
Do not tension the belt
until the crankshaft bolt is
torqued to the proper torque!
(Fig.8)
9.
Install the brake disc with two of the
socket head screws installed. Do
not use Blue Loctite yet because
this part of assembly is temporary.
Insert two ½” bolts into the through
holes in the disc and into the slots
machined into the outer
transmission housing. Using a large
screwdriver as shown in
(Fig. 9)
torque the center bolt to 78-
foot lbs.
10.
Remove the brake disc and adjust
the drive belt until it becomes tight.
Refer to
Page 14 and 15 “Checking
the belt tension” and “adjusting the
belt tension” and follow the steps to
properly tension the belt.
11.
Remove a fill/drain plug from the
transmission and rotate the hole to
12 o’clock.
(Fig. 10)
Fill the
transmission with 1-1/2 oz of Mobil
1 4T 10W-40 Racing Oil using a
syringe with a hose.
(Fig. 11)
(syringe is provided with each
engine when shipped) Reinstall the
fill/drain plug. Install the brake disc
using the four 5/16” socket head
screws using a 3/16” hex socket with Blue Loctite and the two ½’ bolts and large
screwdriver to hold disc. Torque the socket head bolts to 200-inch lbs. or 16.6-foot
lbs.
(Fig. 12)

Reinstall the brake assembly.
(Fig. 13)
Check the clearance of the brake shoes to
the brake plate. The required clearance is .063”. We use two strips of .063”
material long enough to check the clearance on all four brakes at once. To adjust
the
clearance, you must loosen the 4 cap screws using a ½” socket. Then you
screw in the socket set screws until the brake shoes push the .063” strips against
the brake plate.
(Fig.14-15)
Now torque the four cap screws to 200 In. Lbs. to
secure the adjustment. If you do not have these strips you can loosen the four cap
screws with a ½” socket and screw the socket set screws in until the brake pads
touch the brake plate. Now unscrew the set screws one full turn on each screw and
torque the cap screws to 200 In. Lbs.
The set screw is 3/8” x 16 threads per inch.
One full turn = .063”
