Changing Oil con’t
FLOAT & Vanilla Forx - Right Side
The right leg of FOX FORX contains the damper. The damper is a precision component that controls the compression and
rebound of your FOX FORX. If your cartridge ever loses oil, be sure to complete these 9 steps to ensure that you have the
proper volume of oil in the damper. Use only FOX Suspension Fluid in your FOX FORX.
NOTE: Too much oil will cause hydraulic lock-out of the fork. This is a serious condition and could lead to loss
of control and serious or fatal injury.
The following tools and supplies will be needed: 26mm 6-sided socket, 10mm wrench, 2mm hex wrench, 1.5mm hex
wrench, torque wrench, plastic faced hammer, small screw driver, drain pan, FOX Suspension Fluid plus a FOX High
Pressure Air Pump and FOX FLOAT Fluid.
Step 1 - Step 1a -On R models, simply remove the right (damper) side top cap with a 26mm 6-sided socket.
Step 1b -RL and RLC models require that the adjuster knobs be removed as shown on page 14. Remove
the red rebound knob by firmly holding the red knob from turning and loosen screw with a 2mm hex
wrench.
Step 1c -Remove the lock-out lever with a 1.5mm hex wrench by loosening the three set screws and
carefully lifting the lever. Do not remove the set screws. There are 3 balls in the lockout lever. The 3
balls are held in place by grease. Do not lose the three balls in the lock-out lever.
Step 1d -Remove the low-speed compression knob on RLC models. Below the low-speed compression
knob is a detent ball and spring which sit in a counterbore in the topcap. Check that the ball is
positioned in the hole by pressing on it with a small screwdriver and feeling for the force of the
spring.
Step 1e -Loosen and unscrew the damper topcap with a 26mm 6-sided socket.
Step 2 - On RLC models, remove the blue blow-off threshold knob with a 2mm hex key wrench.
Step 3 - Loosen the right side bottom nut with a 10mm wrench or socket 3-4 full turns. Place a clean drain pan under the
right leg and tap lightly with a plastic hammer on the nut to loosen the damper from the lower leg. Unscrew and
remove bottom nut and washer. Push up on the shaft and let the oil drain.
