Inspect piston rod () and cylinder () for wear, scratches, and dents. Replace if damaged.. Inspect spool valve () for wear. Replace if necessary. spool valve should move smoothly and freely with no force by holding in a vertical position. If it does not, it can cause the motor to stall. Reassembling the Hydraulic Motor. Separate spool/sleeve set (). Place o-rings () onto sleeve. Lubricate o-rings with hydraulic oil. Gently push the sleeve into cylinder head () 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. CAUTION Connecting Pin Retaining Ring Do not use Piston Lube pump packing lubricant. It is a solvent and will severely damage seals and O-Rings of the hydraulic motor.. Install o-rings () on trip retainers (). Install trip retainer balls () followed by springs () which, when installed, will hold spool/sleeve set () in proper place for assembly.. Install sleeve retainer () followed by snap ring () into cylinder head (), which will hold valve sleeve in place. Install o-ring () in the o-ring groove of the cylinder head.. Replace lower seal () in motor/pump block (). Be sure the open portion of the seal is facing upward (V). This seal requires no special tool.. Place piston rod () in vise. Inspect valve rod assembly (0) for any damage. Make sure the lock nut at the bottom of the valve rod assembly (0) is secure. DO NOT remove. Then, place into piston rod () as illustrated. Install o-ring (), lubricating it well and replacing piston () onto piston rod (). Put one drop of blue Loctite on the piston retainer screw (). Tighten piston retainer screw until piston is locked into place. Check valve rod assembly (0) for normal spring action at this time.. Install piston seal () with lips facing downward. Carefully install o-ring (). Expand the ring and stretch it sufficiently for installation.. With motor/pump block () still in vise, install lower seal () 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.. Pre-lubricate the piston and valve rod assembly with Coolflo hydraulic fluid (P/N 0-). Install piston rod () into motor/pump block () with a gently pushing and rotating motion to work the piston rod in through the seal (). NOTE: Inspect the bottom of piston rod () for nicks or sharp areas that could damage the piston seal during installation through the motor/pump block ().. Replace the connecting pin and retaining ring. 0. Install o-ring () on cylinder wall. Lubricate ring and inner wall. With the piston rod held firmly, the cylinder should be gently driven over the piston seal with a rubber mallet. Tightly thread the cylinder into motor/pump block ().. Raise piston rod () to top position and thread lock ring () all the way up on upper threads of cylinder ().. Pull valve rod assembly (0) up as far as it will travel and grasp it with vise grip pliers. Then install cylinder head (), already assembled, over valve rod until the top threads of the valve rod pass through the top of the spool/sleeve set (). The valve rod threads must be clean and free of oil. Place one drop of blue Loctite on threads of flex lock nut () and thread nut onto valve rod to full tight position (do not over-tighten) while holding valve rod below with vise grip pliers.. Thread cylinder head () down onto the cylinder () and then back off just enough to reassemble hydraulic fittings and motor tube (). Tighten lock ring with spanner wrench to hold cylinder head in position.. The tee assembly () and the elbow () use an o-ring () to seal on the outer diameter (O.D.) of the motor tube (). The O.D. of the motor tube should be free of scratches or sharp edges. The lock nuts on these fittings first should be hand tightened, then wrench tightened another half turn.. Install o-ring () onto cylinder head plug (). Tighten. P/N -, REV B 00 Titan Tool Inc. All rights reserved.
