ADJUSTMENTS AND ALIGNMENTS

6-3 INTRODUCTION.

This section provides the procedures necessary to perform adjustments and alignments to the anchor windlass. Some adjustment and alignment procedures may require that the component be partially disassembled.

6-4 HYDRAULIC VALVE CAR

TRIDGE ADJUSTMENTS.

The hydraulic power system includes a counterbalance valve cartridge and a relief valve cartridge, which are located in the hydraulic valve block.

6-4.1 COUNTERBALANCE VALVE CAR

TRIDGE ADJUSTMENT. The pressure ad justment of the counterbalance valve serves as a manual load release, so an actuator can be lowered under load, even if pilot pressure or pump flow is not available.

Make adjustments as follows:

NOTE

The counterbalance valve cartridge operates over a 0 to 60 gpm range. It is also used in a hydraulic system where adjustment is seldom changed after installation.

a. Adjustment of the counterbalance valve cartridge is done with the hydraulic system in operation. Refer to paragraph 2-4.2.2.

b. Loosen the locknut on the adjusting screw (figure 6-1).

6-2

CAUTION

To prevent damage to equip ment, never adjust the valve cartridge pressure higher than the pump system pressure.

I

I I ,, NOTE

The counterbalance valve cartridge adjustment range is 1000 to 4000 psi, the standard setting is 3000 psi, and the check poppet opening pressure is 4 psi.

c. Using the proper size hex wrench, adjust the counterbalance valve cartridge.

Screw the adjusting screw out to increase the hydraulic oil pressure setting; screw in to release the load.

d. Observe hydraulic system pressure on the pressure gauge.

e. While holding the adjusting screw stationary, tighten the adjusting screw locknut.

f. Test adjustment while operating the anchor windlass.

6-4.2 RELIEF VALVE CARTRIDGE

ADJUSTMENT. The relief valve cartridge regulates the maximum system hydraulic pressure. Make adjustments as follows:

89581-BP-MMA-010 I

NOTE

The relief valve cartridge oper ates with a maximum allowable leakage of two cu hie inches a minute at 1000 psi. The range of operation is 0 to 100 gpm.

a. Adjustment of the relief valve cartridge is done with the hydraulic power system in operation. Refer to paragraph 2-4.2.2.

b. Loosen and remove the cap over the valve cartridge adjusting screw.

c. Loosen the locknut on the adjusting screw (figure ~ 2).

NOTE

The relief valve cartridge con trols concealed adjustment is + .50, with adjustment ranges of 100 to 3000 psi. Its standard setting is 1000 psi.

d. Using the proper size hex wrench, adjust the relief valve cartridge. Screw in to increase the pressure setting; out to decrease. (The setting is stamped on the cartridge hex.)

~5 FLEXIBLE COUPLING ALIGN

MENT.

The electric motor and hydraulic pump shafts are connected by a flexible coupling.

With the electric motor and hydraulic pump mounted in place on the reservoir, align the flexible coupling as follows:

1 CAUTION

To prevent excessive insert wear, avoid poor flexible coup ling alignment.

NOTE

The electric motor and hydraulic pump shaft keys and coupling halves are installed on their respective shaft. The tightening screw is located over the shaft key with the coupling insert in place.

a. For visual inspection, place a straight-edge at the top and side of the coupling. See figure ~3.

b. Place a .005-inch feeler gauge under the straight-edge for final inspection. This will indicate parallel and angular alignment.

c. Before tightening the coupling setscrews, run the motor to see if the coupling separates or tends to creep.

Recheck for angular alignment, then tighten the two setscrews (figure ~4).
