3. Insert the rope through the hole in the roller and tie

a knot in the end; then wrap the rope counterclock-

wise around the roller leaving approximately 50

cm (20 in.) of rope free of the roller.

4. Apply low-temperature grease to the main spring

and hub.

5. Align the hook in the end of the main spring with

the notch in the roller.

6. Carefully slide the roller over the hub and engage

the spring with the roller.

7. Install the return spring making sure the end is

properly installed in the hole in the roller; then

install the pawl making sure the return spring is

properly preloaded.

8. Slide the end of the rope through the rope guide of

the case; then tie a slip-knot in the rope.

9. Place the friction spring into position on the fric-

tion plate making sure the head of the spring is

opposite the flat of the inner hole. Apply a low-

temperature grease to the plate.

B524

10. Place the plate into position making sure the flat of

the inner hole is correctly positioned in the hub.

Apply blue Loctite #243 to the threads; then

secure the plate with a washer and nut. Tighten the

nut to 1.4 kg-m (10 ft-lb).

B526

11. With 50 cm (20 in.) of rope exposed, hook the

rope in the notch of the roller.

12. Rotate the roller four or five turns counter-clock-

wise; then release the rope from the notch and

allow the rope to retract.

13. Pull the rope out two or three times to check for

correct tension.

„NOTE: Increasing the rotations in step 12 will
increase spring tension.

INSTALLING

1. Place the starter assembly into position against the

magneto case.

2. Secure the starter with cap screws. Tighten to 1

kg-m (7 ft-lb) on the L/C models or to 1.1 kg-m (8

ft-lb) on the F/C models.

„NOTE: Before tightening the cap screws, slowly
pull the recoil rope until the pawl engages; then
tighten the cap screws. This will center the recoil
against the magneto case.

3. Thread the rope through the bushing in the con-

sole; then install the handle and secure with a knot.

Seat the cap.

4. Release the slip-knot in the rope.

Recoil Starter

(570/800/1000 cc)

REMOVING

1. Tie a slip-knot in the starter rope below the con-

sole and allow the rope to slowly retract against

the starter case.

2. Remove the knot at the handle, remove the handle,

and account for the handle cap; then thread the

rope through the bushing in the console.

3. Remove the bolts/cap screws securing the starter

assembly to the magneto case; then remove the

starter assembly.

DISASSEMBLING

1. Secure the recoil starter in a vise.

2. Rotate the roller counterclockwise until the

notch of the roller is near the rope guide in the

case. Guide the rope into the notch and slowly

allow the roller to retract until all recoil spring

tension is released.

FS238A

3. While exerting downward pressure on the friction

plate, remove the bolt/bolt w/washer.

FS239

4. Slowly release the friction plate and lift the plate

with pawl activator free of the recoil roller.

FS240

5. Remove the pawl activator from the friction plate.

FS241

6. Remove the pawl and the return spring; then

remove the friction plate spring.

7. Carefully lift the roller free of the case making

sure the main spring does not accidentally disen-

gage from the case. Account for the bushing.

8. Remove the main spring from the case by lifting

the spring end up and out. Hold the remainder of

the spring with thumbs and alternately release

each thumb to allow the spring to gradually release

from the case.

„NOTE: Do not remove the main spring unless
replacement is necessary. It should be visually
inspected in place to save time.

9. Unwind the rope from the roller, untie the slip-

knot, and remove the rope.

CLEANING AND INSPECTING

„NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is
necessary.

1. Clean all recoil starter components.

2. Inspect springs and pawl for wear or damage.

! WARNING

Always wear safety glasses when servicing the
recoil starter.

! WARNING

During the disassembly procedure, continuous
downward pressure must be exerted on the reel so it
does not accidentally disengage and cause injury.

! WARNING

Care must be taken when allowing the recoil roller to
unwind. Make sure all spring tension is released
before continuing.

! WARNING

Care must be taken when lifting the roller free of the
case.

3. Inspect the roller and case for cracks or damage.

4. Inspect the center hub for wear, cracks, or damage.

5. Inspect the rope for breaks or fraying.

6. Inspect the main spring for cracks, crystallization,

or abnormal bends.

7. Inspect the handle for damage, cracks, or deterio-

ration.

1. Hook the end of the main spring around the

mounting lug in the case.

2. Insert the main spring into the case; then wind it in

a counterclockwise direction until the complete

spring is installed.

„NOTE: The main spring must seat evenly in the
recoil case.

FS242

3. Insert the rope through the hole in the roller and tie

a knot in the end; then wrap the rope counterclock-

wise around the roller leaving approximately 50

cm (20 in.) of rope free of the roller.

4. Apply low-temperature grease to the main spring

and hub.

5. Align the hook in the end of the main spring with

the notch in the roller.

6. Carefully slide the roller over the hub and engage

the spring with the roller; then install the bushing.

FS243

7. Install the return spring making sure the short leg

of the spring is properly installed in the hole in the

roller; then install the pawl making sure the return

spring is properly positioned in the notch of the

pawl.

FS244

8. Slide the end of the rope through the rope guide of

the case; then tie a slip-knot in the rope.

9. Apply a low-temperature grease to the friction

plate. Place the pawl activator into position on the

friction plate making sure the arms of the activator

are properly positioned to the pawl.

FS240

10. Place the friction plate into position allowing it to

rest on the friction plate spring; then install the

bolt/bolt w/washer (coated with blue Loctite #243)

and thread the bolt in until it contacts the friction

plate.

FS245

11. Press down on the friction plate and tighten the

bolt to 1.5 kg-m (11 ft-lb).

FS246

12. With 50 cm (20 in.) of rope exposed, hook the

rope in the notch of the roller.

13. Rotate the roller four or five turns counter-clock-

wise; then release the rope from the notch and

allow the rope to retract.

14. Pull the rope out two or three times to check for

correct tension.

„NOTE: Increasing the rotations in step 13 will
increase spring tension.

INSTALLING

1. Place the starter assembly into position against the

magneto case.

2. Secure the starter with cap screws. Tighten to 1.1

kg-m (8 ft-lb).

„NOTE: Before tightening the cap screws, slowly
pull the recoil rope until the pawl engages; then
tighten the cap screws. This will center the recoil
against the magneto case.

3. Thread the rope through the bushing in the con-

sole; then install the handle and secure with a knot.

Seat the cap.

4. Release the slip-knot in the rope.

Arctic Power Valve

(APV) System

„NOTE: The servo will activate once at APV cycle
RPM. If the servo cycles three times, cable length
adjustment or valve inspection is required.

„NOTE: The 800 cc and 1000 cc have a three-stage
exhaust valve system. The stages are closed, mid-
open, and full-open. Each model has a designated
RPM at which the system is synchronized and
checked by the ECU for proper operation. This
occurs once each time the engine is started. The
800 cc system is checked at 4800 RPM and the
1000 cc system is checked at 6100 RPM (Crossfire/
F-Series) or at 6270 RPM (M-Series).
