Control Valve Assembly
Refer to Dwg. MHP2036 on page 24.
Reverse Valve Assembly
1. Insert reverse valve (943) into bushing (944) with ball slot
oriented UP, approximately 2-1/2 in. (64 mm).
2. Insert bushing (944) and reverse valve (943) into valve
housing (917) from exhaust flange side, ensuring that groove
in bushing is aligned with pin (945).
3. Insert ball (916) onto reverse valve platform. With finger,
push ball (916) in housing until ball hits end of reverse
valve.
4. Holding ball (916) in position on reverse valve platform,
rotate reverse valve from neutral position to approximately
45 degrees in either direction. Ball will ‘walk’ up side of
reverse valve platform and move in ball hole in bushing.
• Do not rotate reverse valve past a 90 degree position, it may
result in the ball (916) falling in motor.
5. Slowly push reverse valve, while still in the 45 degree
position, the rest of the way in housing until flush with
surface. From other side of valve rotate reverse valve back to
neutral position, ball should be seated in ball slot at that time.
6. Lubricate ‘O’ ring (942) and place it in groove in exhaust
flange (955).
7. Secure exhaust flange (955) to valve housing with capscrews
(901) and washers (902).
8. Insert ‘O’ ring (941) into seal bracket (939). Lubricate ‘O’
ring (942) and place into groove in seal bracket.
9. Place seal bracket over end of reverse valve. Using finger
pressure, press until seal is seated on reverse valve and seal
bracket is seated on valve housing. Secure with washers
(924) and capscrews (925) and (938).
Pilot Valve Assembly
• For easier installation it is recommended to use IR pilot valve
tool (920). This must be purchased separately.
1. Install pilot valve assembly (910).
2. Apply thread sealant Loctite 567
®
to pilot valve assembly
(910), place pilot valve assembly into valve housing. Use a
large flat tipped screw driver to engage slots in pilot seat and
tighten until pilot assembly is 1/8 in. (3.175 mm) from
housing bore.
3. Insert plug (912) and tighten.
Piston Assembly
1. Lubricate and install ‘O’ rings (921) and (923) on piston
(922).
2. Insert assembled piston into valve housing (917) from
handle side.
3. Secure with gasket (918), piston cover (919), washers (902)
and capscrews (901).
4. Place poppet seal (907) into poppet cap (906). Place this
assembly into valve housing and seat on piston (922).
5. Place spring (905) over this assembly.
6. Secure with gasket (904), poppet cover (903), washers (902)
and capscrews (901).
Handle Assembly
1. Place spring (937) over reverse valve handle end in seal
bracket.
• Spring (937) will have to be ‘Cocked’ over stud in seal
bracket. This will ensure handle returns to neutral.
2. Place handle assembly over reverse valve end. Slide handle
will have to be lifted slightly to allow pin to fit into slot in
seal bracket.
3. Secure handle assembly (930) to reverse valve with tab lock
washer (909) and capscrew (901), torque to 15 ft lbs. (21
Nm). Washer (909) has small tab on side, engage with small
hole in handle.
4. Bend tabs of washer (909) over flats of capscrew.
5. Press plug (935) into handle assembly to cover capscrew.
Check control handle movement. Correct any discrepancies.
Testing
Operational Test
Prior to initial use, all new or repaired motors shall be tested to
ensure proper operation.
To initially ‘break in’ new or overhauled motors, operate motor
without load, in both directions, for 15 minutes at 100-200 RPM.
Motor should operate smoothly without sticking, binding or
knocking. Correct any problem before mounting motor to any
component.
