AP-1055B (8BM),
BG-2455C (6TN) Asphalt Pavers
NOTE: THIS PROCEDURE SHOULD BE USED IN CONJUNCTION WITH THE REMOTE BLEED INSTALLATION PROCEDURE.
1. Connect the auxiliary hydraulic oil supply hose to the tension manifold.
2. Open needle valve on top of the manifold 1 to 2 turns.
3. Connect discharge hose to the high pressure disconnect (from update kit), leave the pressure relief nut, on the female side of the quick disconnect, in the "off" or "closed" position. Place other end of hose into a bucket to capture the oil/air mixture while bleeding.
4. Stand clear of track and start engine. The ram will rapidly move the front idler forward and put tension on the track. The horn should stop sounding within a couple of minutes.
NOTE: If the horn does not shut off, the auxiliary pump pressure should be raised to reopen the track tensioner switch.
a) Connect a 3500 psi pressure gauge to the test port on the hopper valve manifold.
b) Start engine, adjust the auxiliary pump compensator to raise the pressure to 2300 psi.
5. Open the pressure relief nut at the disconnect and allow the oil/air mixture to escape the ram and manifold. The mixture will appear white and frothy and discharging air can be felt passing through the hose.
6. When all the air has passed from the ram, shut off the high-pressure relief nut at the quick disconnect and unplug the discharge hose. Replace the rubber boot on the male end.
7. Shut off the needle valve for the oil supply at the manifold.
NOTE: Applying 10 ft/lbs. over torque can result in breakage of the needle valve.
8. Shut off the engine, allow the auxiliary system pressure to drop to zero and disconnect the supply hose at the manifold and replace the dust caps on the quick disconnect coupler.
9. Restart the engine and reset the auxiliary pump pressure back to 2000 psi, the normal operating pressure of the auxiliary system.
