Maintenance

Remove the ‘

head wrench/nut driver. Retain the screw/o-ring for reassembly.

 

‘A’ reservoir screw

Remove the ‘

’ reservoir screw using a 4 mm (5/32 in) hex key. 

Retain the screw for reassembly. It is recommended that the 

bonded washer/rubber seal is replaced. It is Parker Oildyne part 

number 415067.

Keep the two plastic spacers positioned between the power 

unit adapter and reservoir ‘ears’. They will be needed for 

reassembly. Retain the screws and the reservoir seal for 

reassembly also.

The ‘

’ reservoirs use an adapter plate between the 

power unit adapter and the larger reservoir flange. Remove 

the oil from the tank using a siphon through the reservoir filler 

port. Remove the four screws holding the reservoir flange to the 

adapter plate using an 8 mm (5/16 in) socket head wrench/nut 

driver. Keep the screws for reassembly.

Inspect the suction screen – one for single direction power 

units, two for reversible circuits. If any screen is damaged or 

in any way plugged up, it should be replaced.  In vertically 

mounted configurations, the strainer is pressed onto the pump 

suction leg.  With a pair of pliers clamped on the strainer’s 

aluminum ring, gently pull the strainer off of the pipe.  If 

necessary, twisting the pliers will help remove the strainer. In 

horizontally mounted configurations, the suction strainer is 

usually installed over an o-ring of the suction elbow.  Again, 

using a pair of pliers clamped on the strainer’s aluminum ring 

gently pull the strainer from the elbow.

Suction Screen Installation 

Vertical mount reservoirs:

Insert the suction screen into a 16 mm (5/8 in) socket. Using 

a hammer, tap the socket and strainer onto the pump suction 

leg so that it is secure on the pump leg, but before the bottom 

of the suction leg touches the strainer screen itself. 

NOTE: If 

the suction leg end is touching the screen itself, the useful 

screening area of the strainer is greatly reduced.  

Horizontal mount reservoirs:

Using fingers only, grasp the aluminum ring of the strainer and 

push the strainer onto, and over the o-ring on the elbow. When 

the strainer is properly installed the o-ring on the elbow will 

retain it.

Reservoir reinstallation

‘A’ reservoir

Invert the power unit so the motor end is down. Ensure the 

rubber seal is in place in the power unit adapter pilot, against 

which the reservoir will mount. Insert the reservoir screw/o-ring 

through the hole in the reservoir end. The pump’s mounting 

leg will be very close to the reservoir end. Align the screw with 

pump’s mounting leg threaded hole. 

This is a self tapping 

screw so following these instructions is critical to ensure 

a proper installation. 

Failure to ensure the screw thread and 

pump mounting thread are aligned can cause a new thread to 

be formed or cross-threading. Either outcome will not provide 

an adequate tightness. Turn the screw counter-clockwise in the 

pump’s mounting leg hole thread, until an audible ‘click’ is heard 

and felt by the fingers. Only at this point will you turn the screw 

clockwise to begin tightening the screw into the pump mounting 

leg.  Tighten to a torque of 2.8 +/- .5 Nm (25 +/- 5 in-lbs). Follow 

the complete mounting, filling, bleeding and startup instructions 

on page 15.

‘B’ reservoir

Invert the power unit so the motor end is down.  Ensure the 

rubber seal is in place in the power unit adapter pilot, against 

which the reservoir will mount. Insert the reservoir screw and 

new bonded washer/rubber seal (with the seal end facing the
