  FILL CARTRIDGE TUBE
  
1)

 Hang the fork upside down.  Zip tie or tape the outer tube as needed to prevent it from sliding down as you work.

Partially insert ctg rod. Hold up enough to pour oil under mv piston.  Add about 400cc fluid.
    2)

Let ctg rod drop and stroke a couple times.  Stroke slowly or fluid will shoot out top of bullet. 

Slowly add oil, half covering side holes until the outer space is filled.  Tipping the tube at an angle speeds the filling process.  

Then fill to top of threads and install base bolt. 

Thighten base bolt.  Use ctg holding tool as needed to hold ctg rod if base bolt does not catch.

    3)

We mount fork in floor vise to hold down during the bleeding process.  
    4)

Install fork cap so you have something to grab. 

Fill tube half way with fluid and pull up on ctg rod a few times to bleed/burp air bubbles. 
-- Stroke the ctg rode full length 2-3 times and re-burb. 
-- Then stroke ctg rode 2-3 inches a few times and re-burp. 

This method removed all air bubbles.


NOTE: If you use the 2014 hydrostop or MX-Tech Huck valve, you will need to burp 20-30 times to remove all the air.
