Refitting the front fork (1100 ABS)
Before removing the front forks, it is first necessary to remove the following parts:
 
Important
Not all the components described in this chapter are available as individual replacement parts: however they are indicated for clearer explanation of the procedure.
 
Loosen the clamp screws (25) holding the fork legs to the steering head (23).
Loosen the clamp screws (24) securing the fork legs to the bottom yoke (22).
Withdraw the fork legs (2) and (1) downwards in order to carry out to all the necessary overhaul operations.
Overhauling the front fork (1100 ABS)
Note
It is advisable to loosen the top cap (17) when the fork leg is still fitted to the motorcycle.
The specific tools for the revision of the fork, are described in Sect. C 4, Specific tools for the frame.
Loosen the spring preload adjuster (A) before unscrewing the plug (17).
Disassembly of the front fork legs.
Unscrew the top cap (17).
Slide plug (17) off the stanchion tube (18), still mounted on the cartridge, and the rubber washer (14).
Install the special tool no. 88713.0957, by inserting pins (A) in the holes of the preload tube and tightening screw (B).
Push the tool downwards to compress the spring and then fit the tool spacer (C) under the cartridge lock nut (8).
Apply a wrench to the flats (D) and counterhold the lock nut to loosen the top cap (17).
Remove the plug (17) and the rubber washer (14).
Install tool no. 88713.0958 screwing it onto cartridge rod.
Push downwards to overcome the force of the spring and remove the spacer (C).
Remove tool no. 88713.0957 and slide out the preload tube (12) together with spring retainer (13) and joint (11).
Remove the spring (9) and pump the outer tube (18) and the damper (8) to expel the oil from the fork leg.
Warning
This movement generates pressure so that the oil will be rapidly expelled from the fork leg.
Aim the jet of oil into a previously prepared container and avoid contact with fork oil.
Clamp the inner tube (6) in a vice with soft-faced jaws.
Unscrew the screw (3).
Remove the special screw (3), keep the special washer (4).
Remove the complete damper assembly (8) and locating ring (10).
Slip the dust seal (29) off the outer tube (18), prising it off with a screwdriver.
Remove the circlip (28).
 
Important
Take care not to damage the outer tube (18) or inner tube (6).
To separate the outer tube (18) from the inner tube (6), pull the inner tube sharply outwards repeatedly to gradually displace the bottom bush (7).
Insert the tip of a screwdriver in the slit in the bush (15) and open it up sufficiently to slide the bush off the inner tube.
Remove the following parts from the inner tube (6):

Inspection of the front fork (1100 ABS).
Place the spring on a flat surface and measure the free length (L).
Service limit:
298.5 mm.
Renew the spring if the length is not within the specified limit.
Inspect the outer surfaces of both fork inner tubes and the internal surfaces of both outer tubes. They must be free from scoring, steps, or dents.
Check that the outer tubes are straight:
maximum allowed error 0.10 mm.
Whenever the inner tube is removed from the outer tube it is good practice to renew the bushes (15) and (7) as well as the seals (27) and dust seal (29).
Loosen and remove the plug (21) located on fork bottom end.
Remove the taper needle (E).
Reassembly of the front fork (1100 ABS)
Clamp the inner tube in a vice.
Protect the end of the stanchion tube with tape.
Fit the duly greased O-ring (20) onto plug (21).
Upon reassembly, screw the taper needle (E) so that it seats against the fork bottom end, then tighten plug (21) until reference marks (G) are perfectly aligned.
Important
Before installation, smear the sliding edges of oil sealing ring (27) with fork oil or oil seal grease.
 
Fit the following components to the inner tube:
-
-
-
-
Important
Install the sealing ring with the marked surface facing the dust seal.
 
Fit the following components:
-
-
Remove the adhesive tape from slider end.
Note
Before assembling the two parts, lubricate the sliding surfaces of the bushes with fork oil.
 
Install the outer sleeve (18) and push the guide bush (7) and the cap (26) into the outer sleeve using the sealing ring tool (H, part no. 88713.1096).
Drive the oil sealing ring (27) into the outer tube using the same tool.
Fit the circlip (28) and the dust seal (29).
Important
The outer sleeve must slide freely along the slider. Only support the sliders and the outer sleeve with your hands so not to dam­age the sealing rings and the pilot bushes.
Insert the locating bush (10).
Fit the complete damper cartridge (8) on the slider (6).
Fit the seal (4) and tighten the adjuster screw (3).
Hold the left fork leg assembly (1) in a vertical position and fill with fork oil, using 524±2.5 cc of the specific oil.
Install tool part no. 88713.0958 to cartridge.
Pump to force the oil to fill internal volume completely.
Check the quantity of oil measuring the distance of the level from the end of the outer tube (18).
This distance should be 90 mm.
Clean off any oil from the spring (9) joints (11), (13) and the tube (12) before refitting.
Note
Install the spring (9), ensuring that the end with tighter coils is towards the bottom of the fork.
 
Fit the following components:
-

Install tool no. 88713.0957, i.e. the one used for removing the preload tube (12). Press tool down and set spacer (C) under the cartridge (8) lock nut. Remove service tool no. 88713.0958. Fit the rubber washer (14) and tighten top plug (17) on the damper cartridge (8). Hold cartridge lock nut with a hexagon wrench then tighten the top plug to 20±2.5 Nm. Remove spacer (C) by push­ing tool (part no. 88713.0957) downward.
Warning
Plug (17) adjuster (A) shall be fully home against damper cartridge (8) thread.
Lift the outer sleeve (18) and tighten the top plug (17) to a torque of 34±5 Nm. Set the adjusters according to riding requirements.
Refit the front fork (1100 ABS)
Refit the fork legs, positioning them at the height shown in the figure relative to the upper surface of the bottom yoke.
Warning
The difference in height between the two legs must not exceed 0.1 mm.
 
Position the fork legs, then tighten the screws (24) and (25) to the specified torque (Sect. C 3, Frame torque settings) following a 1-2-1 sequence for the screws (24).
Important
If the clamp screws (24) and (25) were removed on disassembly, smear the threads with the specified grease before tightening.
 
Warning
Do not use the motorcycle without the front mudguard fitted to avoid the risk of the brake pipes fouling the wheel on braking.
