Reassembly of Hydraulic Motor
1. Separate spool/sleeve set (5). Place o-rings (6) onto sleeve.
Lubricate o-rings with hydraulic oil. Gently push the sleeve
into cylinder head (11) with the flatter side of the sleeve facing
out. Use a nylon rod to tap sleeve down until it reaches its full
depth. Do not use any other type of tool that might damage or
leave particles or residue on the sleeve. Install the spool
through the top of the cylinder head, down into the sleeve.
Do not use Piston Lube pump packing lubricant. It is a
solvent and will severely damage seals and O-Rings of the
hydraulic motor.
2. Install o-rings (2) on trip retainers (1). Install trip retainer balls
(4) followed by springs (3) which, when installed, will hold
spool/sleeve set (5) in proper place for assembly.
3. Install sleeve retainer (13) followed by snap ring (14) into
cylinder head (11), which will hold valve sleeve in place.
Install o-ring (12) in the o-ring groove of the cylinder head.
4. Replace lower seal (24) in motor pump block (25). Be sure
the open portion of the seal is facing upward (V). This seal
requires no special tool.
5. Place hydraulic piston rod (21) in vise. Inspect valve rod
assembly (20) for any damage. Make sure the lock nut at
the bottom of the valve rod assembly (20) is secure. DO
NOT remove. Then, place into hydraulic piston rod (21) as
illustrated. Install o-ring (19), lubricating it well and replacing
piston (17) onto hydraulic piston rod (21). Put one drop of
blue Loctite on the piston retainer screw (16). Tighten piston
retainer screw until piston is locked into place. Check valve
rod assembly (20) for normal spring action at this time.
6. Install piston seal (18) with lips facing downward. Carefully
install piston seal (18). Expand the ring and stretch it
sufficiently for installation.
7. With motor pump block (25) still in vise, install lower seal
(24) by pushing it towards its groove with a properly sized
blunt rod. Then complete installation with the fingers. No tool
is necessary. Do not twist the seal.
