The hydraulics for the secondary cylinder require a 90 degree elbow on one side, and a needle valve on the other. You can use whatever fittings you so desire to achieve this, heres what we used.

Tools Required

  • Various wrenches
  • Crescent wrench

Materials Required

Note: NPT means national pipe thread, and refers to the interior diameter of the hoses. NPTM means a male end, and NPTF means a female end.

  • Thread tape
  • 3/8" NPT Hex nipple (2) Buy
  • 1/2" NPT to 3/8" NPT bushing (2) Buy
  • 1/2" NPTF to 1/2" NPTF 90 Elbow (1) Buy
  • 1/2" NPT Needle Valve Buy
  • 1/2"x36" NPTM Hydraulic hoses (2)

Fabrication Steps

  • Its reccomended you wait to put the hoses on the cylinder until its in place, so you can get good leverage.
  • Thread tape is necessary between each connection unless otherwise stated.
  • Always wrap thread tape clockwise when facing the threaded portion.
  • Always keep the end caps on hoses and fittings until you need to take them off. They need to stay protected inside.

The needle valve hose

The needle valve hose.
  1. Clamp the bushing in a vise and tighten the 3/8" hex nipple to it. Remove these from vise.
  2. Clamp one 36" hydraulic hose into a vise.
  3. Tighten the needle valve down onto it.
  4. Clamp the needle valve in the vise.
  5. Tighten the bushing and nipple to it.

The elbow

  • The hose will be attached when the secondary cylinder is being attached. The instructions are just for the elbow.
  1. Clamp the bushing in a vise and tighten the 3/8" hex nipple to it. Remove these from vise.
  2. Clamp the elbow in the vise.
  3. Tighten the bushing and nipple to it.
