Servicing I.F.P.

Style Shocks

NOTE: The following illustration should be used as a reference for proper placement of the valves and the

piston whenever a rebuildable shock is disassembled for the purpose of revalving or rebuilding.

0735-329

9-152

! WARNING

Before servicing a gas shock absorber, first
discharge all pressure from the shock. Remove
the screw from the bottom of the shock and
insert the Shock Inflation Needle (p/n 0644-158).
Open valve until all pressure is released. Failure
to do this may cause personal injury.

DISASSEMBLING

1. Remove the shock from the snowmobile.

2. Wash the shock body in parts cleaner; then dry with

compressed air to remove sand and dirt.

! WARNING

When using compressed air to dry components,
always wear safety glasses.

3. Place the shock into the Gas Shock Retaining

Blocks (p/n 0644-142); then remove shock eyelet
mounting axle and bushings from end cap.

It is important that the Gas Shock Retaining
Blocks (p/n 0644-142) are used during both
disassembly and assembly. Any other method of
s e c u r i n g t he s h o ck b ody d u r i n g t h e s e
procedures may deform the shock body
cylinder.

NOTE: A paper shop towel between the shock

body and retaining blocks will help prevent scuffing
of the shock body.

4. Remove the screw from the bladder housing on the

bottom of the shock. Discharge all the pressure
from the shock using the Shock Inflation Needle
(p/n 0644-158). Open the valve in filler handle until
all pressure is released.

Fig. 9-449

AG335

5. Using a 9/16-in. wrench, remove the brass bladder

housing from the lower end cap. Account for an
O-ring.

Fig. 9-450

AP014

6. Using a large adjustable wrench (12-in. or 14-in.),

remove the end cap.

NOTE: 1994 and older shocks have Loctite on the

lower end cap. Heating the lower end cap may be
necessary. Use care not to overheat.

AP016DA

! CAUTION

9-153

7. Using a 1-in. open end wrench, loosen the shock

shaft bearing cap a couple of turns.

NOTE: Do not remove the bearing cap at this time.

Fig. 9-452

AP026

8. Turn the shock so that the open end is up. Then

remove the Allen-head screw located in the center
of the floating piston. Account for a small O-ring.

Fig. 9-453

AP022

9. Using a pair of pliers, pull the floating piston

assembly out of the shock body. Account for a
piston ring and an O-ring.

10. Pour the oil out of the shock body.

11. Unscrew the shaft bearing cap and lift the shaft

assemble from the shock body.

Fig. 9-454

AP027

12. Clean the inside of the shock body using clean

parts-cleaning solvent. Blow dry using compressed
air.

NOTE: Do not lay shock parts on a rag as it may

transfer lint to the parts causing internal shock
problems.

! WARNING

When using compressed air to dry components,
always wear safety glasses.

13. Remove the piston ring from the piston. Loosen

(but do not remove) the lock nut from the bottom of
the shock shaft; then clean the piston area with
clean parts-cleaning solvent to remove dirt or
foreign material from between the valves. Dry the
piston and valves completely using compressed air.

! WARNING

When using compressed air to dry components,
always wear safety glasses.

NOTE: If for some reason the piston must be

removed from the shock shaft, it must be installed
with its large seven slots located next to the lock nut
side of the shock shaft.
