Section 2: Actuator Disassembly

Actuator Disassembly

2.6

M18 Pump Disassembly

NOTE:

Refer to dwg. VA-ED-005-1120 for details.

!

WARNING

Disconnect operating pressure. If not already removed, disconnect all operating pressure
from actuator power cylinder.

2.6.1

Place the M18 pump control knob (25 - 200) in the auto position. Use dwg.
VA-ED-005-1120 for this Section.

NOTE:

Control knob (25 - 200) is in front and at the bottom of the M18 pump manifold

(20 - 10 - 10). Using a means of capturing the hydraulic fluid that will be lost during the

following steps. Use a bucket, tub, or large container, etc.

2.6.2

Remove all the piping from the M18 override manifold (20 - 10 - 10) to the
actuator and reservoir (10).

2.6.3

Remove mounting bracket (30 - 90) from the actuator.

2.6.4

Remove all counter-sunk cap screws (30 - 100) from the mounting
bracket (30 - 90).

2.6.5

Remove acorn nut (25 - 450), lock washer (25 - 460), control knob (25 - 200) and
control pointer (25 - 150) from the M18 override.

2.6.6

Remove socket cap screws (25 - 240) from the cover (25 - 140).

NOTE:

Note the bottom two access holes to reach socket cap screws are blocked by instruction
tag (25 - 220) and will need to be removed and replaced (new instruction tag is provided in
service kit).

2.6.7

Pull out quick release pin (20 - 10 - 110) from the pump handle lever (20 - 10 - 90).

2.6.8

Remove socket head cap screws (20 - 10 - 100) from the back brace (20 - 10 - 130).

2.6.9

Remove pipe plug (20 - 10 - 210), spring (20 - 10 - 360) and ball (20 - 10 - 350).
If the back plate (20 - 10 - 320) is not coming out, use soft mallet to gently tap the
open end of stem, control valve (20 - 10 - 280) in order to remove the back plate
assembly and stem assembly.
