Unthread rear clamp bolt (4) using your 5mm hex key.  Remove clamp nut (1) & upper clamp (2).  You can then remove your saddle & the lower clamp (3). clean assembly and put aside until you have check the air pressure at the end of this service.

TIP: Leave front clamp bolt (4) & dont adjust it.  When you reinstall the seat, torque the rear clamp bolt to 8Nm (70 in-lbs) and your seat angle will remain correct.

 

  

STEP 2: REMOVE CARTRIDGE LOCKNUT 

Using your 6mm Hex key,  unthread and remove the cartridge locknut (5).

 

 

STEP 4: REMOVE ACTUATOR FROM LOWER TUBE

Holding the post upside down,  unscrew the green actuator (16) from the lower tube (12) using your 14mm wrench.

Once free of the lower tube (12),  you can slide the lower tube up the upper tube (7) to expose the cartridge (14) & actuator lock bolts (17).

 

STEP 5: REMOVE ACTUATOR FROM CARTRIDGE

Remove the 2 actuator lock bolts (17) using your 2mm hex key.  You can then slide the actuator (16) & foam washer off the bottom of the cartridge (14).

 

 

 

STEP 6: REMOVE CARTRIDGE 

Now that both the cartridge locknut (5) & actuator (16) have been removed,  the cartridge can be pulled out the bottom of the dropper. 

NOTE: 

The cartridge push rod is held into the cartridge (14) by the actuator (16).  When the actuator is off,  the push rod can fall out of the cartridge.  Be careful not to drop the push rod from the new cartridge before or during assembly.

 

STEP 7: INSTALL ACTUATOR

Slide rubber washer and actuator (16) back onto the bottom of the cartridge (14). Thread the actuator lock bolts (17) into the cartridge with your 2mm hex key & snug down.  Do not over tighten as you risk stripping the small 2mm tool interface.
