1 A125162-01 CENTER BALANCE CARTRIDGE

2 A125162-02 SEQUENCE CARTRIDGE

SETTING THE APRON AND PUSHOFF VALVE

The manifold block containing the pushoff sequence valve cartridge and apron sequence valve car-

tridge is used to control two hydraulic circuits with one hydraulic remote. when the tractor hydraulic remote

is activated, oil ows rst to the apron cylinders until they are fully extended. Once the cylinders are fully

extended, the apron circuits’ hydraulic pressure begins to increase. Once the pressure threshold is sur-

passed (which is adjustable. See adjustment section), the sequence valve diverts the oil ow to the pushoff’s

hydraulic circuit. Once the push off is completely extended the operator then reverses the tractors hydraulic

remote. The counterbalance valve will hold the apron open until the push off is fully retracted. The Apron

sequence valve then opens and allows the apron to close.

Setting the valves:

STEP 1 PUSHOFF SEQUENCE VALVE

Loosen the lock nut (9/16”) on the sequence valve cartridge. Turn the setscrew (4mm) clockwise

until the front apron rises before the push-off begins to advance. (Earthmover should be empty) Turn the

adjustment screw an additional 1/4 turn clockwise and tighten jam nut.

STEP 2 Counter Balance VALVE

Loosen the lock nut (9/16”) on the counterbalance valve cartridge. Turn the setscrew (4mm) coun-

ter-clockwise until the apron holds in a raised position while rear gate is being retracted. Turn adjustment

screw an additional 1/4 turn, tighten jam nut. DO NOT tighten adjusting screw more than necessary.
