MAIN (Cont.)
E.
Test and Adjustment of Prestolite Hydraulic Pump (Refer to Figure 4) (cont.)
(2) Test and Adjustment (cont.):
(k) Connect the green lead from the pump motor to the positive terminal of the power supply.
With low pressure indication within the 500 to 800 psi range, the ammeter should read
between 15 to 35 amperes.
– NOTE –
Replace pump assembly if any of the various tests do not
perform satisfactorily.
(l) Disconnect the green lead from the power supply and permit the pressure to drop before
disconnecting the hydraulic lines.
F. Installation of Prestolite Hydraulic Pump (Refer to Figure 3)
(1) Insert grommet in pump base mounting hole.
(2) Insert bushing in grommet.
(3) Place washer over bolt and insert bolt through grommet, bushing and pump base.
(4) Place washer and bushing over bolt. Secure to mounting shelf.
(5) Connect hydraulic lines to pump.
(6) Connect pump electrical leads. Blue wire to gear up solenoid, green wire to gear down solenoid,
and black wire to ground.
(7) Check fluid level in pump. Refer to Chapter 12 for filling instructions.
(8) With airplane on jacks, operate pump to purge hydraulic system of air, and check for leaks. After
operation, recheck fluid level.
G. Removal of Oildyne Hydraulic Pump
The Oildyne hydraulic pump, with reservoir incorporated, is located in the nose section of the
fuselage. Access to the pump is through the access panel in the nose baggage compartment. To remove
pump:
(1) Disconnect the pump electrical leads from the pump solenoid relays and the ground wire from the
battery shelf.
(2) Disconnect the hydraulic lines from the pump. Cap the line ends to prevent contamination.
(3) Remove pump by removing pump attaching bolts.
(4) Cap or plug all ports.
(5) Clean exterior of pump using a dry cleaning solvent to remove accumulated dirt and dust
H. Servicing Oildyne Hydraulic Pump (Refer to Figure 5)
Field service of Oildyne hydraulic pumps is limited to removal, cleaning, and inspecting the hydraulic
fluid reservoir. Should pump malfunction, either replace pump, or return pump to Piper Aircraft, via
the local Piper distributor, for servicing or repairs.
The Oildyne pump incorporates a dipstick to check the quantity of hydraulic fluid in the reservoir.
Replenish only with MIL-H-5606 petroleum base hydrfaulic fluid.
