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.
