System Installation (cont.)
Supply lines; 3500 psi (241 bar, 24 MPa) rating or better
Install to vent valve outlet on pump module. Secure to framework to prevent abuse and abrasion.
Use branch lines to connect to injector banks and groups.
NOTE: Per JIC standards, copper tubing should not be used in lubricant systems.
Supply line recommendations:
Up to 40 ft in any one direction from the pump to the furthest injector bank.
3500 psi minimum working pressure.
1/2 in. ID hose or steel tubing (.049 wall thickness) or 3/8 in. Schedule 40 pipe.
Up to 70 ft in any one direction from the pump to the furthest injector bank.
3500 psi minimum working pressure.
5/8 in. ID hose or steel tubing (.049 wall thickness) or 1/2 in. Schedule 40 pipe.
Branch lines; 3500 psi (241 bar, 24 MPa) rating or better
Limit line length as short as possible. Connect to injector inlet (3/8” npt).

Injector, GL-1, replacement
Group injectors (typical haul truck has 3 groups, right side for right side steering points, left side for left side
steering points and rear for shocks and box joints).
Use branch lines to feed injector groups, no more than 15 injectors per branch line.
Install zerk and cap fitting into either injector outlet (1/8” npt).
Feed lines; 3000 psi (207 bar, 21 MPa) rating or better
Connect to either injector outlet (1/8” npt). No more than one feed line per injector.
Allow hose slack for moving points. Secure to framework to prevent abuse and abrasion.
Feed line recommendations:
Up to 17 ft maximum hose length
3000 psi minimum working pressure.
1/4 in. ID hose.
Up to 26 ft maximum hose length
3000 psi minimum working pressure.
3/8 in. ID hose.
