cap screw (from step 47) to specifications.

„NOTE: On the 1000 cc with alignment pins in
place, install the magneto case on the crankcase
accounting for the different-sized cap screws and
the alignment pins. Tighten cap screws to specifi-
cations.

CM182A

2. Install the front lower engine mounting bracket to

the engine with cap screws (coated with blue Loc-

tite #243). Tighten to specifications.

CM200A

3. Place the engine in position in the chassis; then

install the cap screw and lock nut (A) and (B)

securing the MAG-side engine mounting bracket

and the front lower engine mounting bracket to the

chassis. DO NOT TIGHTEN AT THIS TIME.

742-203B

4. Attach the water pump coolant hose to the front

heat exchanger. Secure with the hose clamp.

CM135A

5. Raise the PTO-side of the engine and support the

engine in this position. Connect the coolant tank

hose to the bottom left outlet on the engine and

secure with the hose clamp.

CM136A

6. With the torque bumper positioned against the

gear case, install PTO-side engine mounting

bracket to the engine with cap screws (coated with

blue Loctite #243) and to the chassis with lock

nuts. DO NOT TIGHTEN AT THIS TIME.

7. From step 6, tighten the PTO-side mounting

bracket-to-engine cap screws (D) to specifications;

then tighten the lock nuts (C) securing the mount-

ing bracket to the chassis (from step 6) to specifi-

cations.

2-116

 8. Tighten the MAG-side engine mounting bracket-

to-chassis cap screw and lock nut (A) (from step 3)

and the front lower mounting bracket cap screw

and lock nut (B) (from step 3) to specifications.

9. Connect all electrical wiring harness plug-ins

making sure all wiring and coolant hoses are

routed properly as noted in removing; then install

the wiring harness wrap.

„NOTE: Use cable ties to secure the wiring har-
nesses as necessary.

10. Place the recoil starter into position and secure the

starter with five cap screws (coated with blue Loc-

tite #243). Tighten (in a crisscross pattern) to spec-

ifications.

CM137

11. Tighten the spark plugs to specifications; then con-

nect the plug wires and on the 800 cc, the knock

sensor plug-in.

CM130A

the oil-injection pump and secure.

CM028A

13. Route the oil-supply hose through the hole in the

chassis with the rubber grommet and to the oil

pump. Secure with the clamp.

CM131B

„NOTE: After securing the oil-supply hose to the
oil pump, remove the bleed screw to allow any air
in the hose/pump to be released.

CM184A

„NOTE: Confirm that the two coolant hoses which
run to the throttle bodies are accessible to connect
and that the fuel line and oil pump linkage are
accessible.

14. Place the throttle bodies into position and secure

with the flange clamps. Verify oil-injection pump

synchronization (see Section 4); then connect the

fuel line to the throttle body assembly and tighten

the clamp securely.

FC051

15. Install the oil pump linkage arm to the throttle

body pulley.

CM129B

16. Connect the two coolant hoses to the throttle body

assembly; then secure with the clamps.

CM131A

17. With the air silencer boot properly positioned on

the throttle body assembly, install the silencer and

secure with the hold-down and the torx-head cap

screw.

„NOTE: It is advisable to install the two front lower
cap screws first to attain proper alignment for the
remaining cap screws.

When installing the throttle bodies, make sure the
gasline hose is properly routed to avoid premature
wear and/or contact with exhaust components.
