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 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 piston rod (21) as illustrated.
Install o-ring (19), lubricating it well and replacing piston
(17) onto 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.
