For routine maintenance, the chart below provides suggested service intervals
for common procedures:
Fork Air Bleeding
Tools required
3mm hex key (Allen wrench)
During normal operation, both fork legs will build up air pressure. This pressure
acts as an additional spring so it must be bled on a regular basis to maintain
consistent suspension operation. Before each ride, loosen the socket head cap
screw located at the front of each fork cap far enough so that any excess
pressure in the leg is relieved. After excess air is bled off, retighten the screw to 5
in-lb. Be careful not to lose or damage the sealing ring that is located under the
head of each bleed screw.
Fork Oil Replacement
Tools required
37mm Fork Cap Tool (MCMUTL37)
22mm closed-end wrench or socket
14mm open-end wrench
Drift punch (12mm OD x 300mm long (1/2” x 12”))
5 & 6 mm hex key (Allen wrench)
Mallet
2.5 wt. Bel-Ray fork oil
Disassembly procedure
1. Remove the front wheel.
a. Loosen the brake-side axle pinch bolts (5mm hex key)
b. Carefully remove the brake side axle cap using a closed-end wrench to
protect the cap from damage. (22mm wrench)
c. Loosen the non-brake side axle pinch bolts (5mm hex key)
d. Using the drift punch (a long 3/8 socket extension will also work),
remove the axle from the fork lugs by placing the punch inside the
hollow axle and tapping lightly on the exposed end with the mallet.
