Hydraulic Motor Replacement Part, Char Lynn 2000 Series disc valve geroler motor repair Reassembly manual


Reassembly


Check all mating surfaces. Replace any parts that have scratches or burrs that could cause leakage. Clean all metal
parts in clean solvent. Blow dry with air. Do not wipe dry with cloth or paper towel because lint or other matter can
get in the hydraulic system and cause damage. Do not use a coarse grit or try to file or grind these parts. Check around the keyway and chamfered area of the shaft for burrs, nicks or sharp edges that can damage the seals when reassembling the bearing housing.
NNote: Lubricate all seals (prior to installation) with petroleum jelly such as Vaseline. Use new seals when
reassembling this motor. Refer to parts list (6-129) for proper seal kit number.


21. Use a press to install exclusion seal in outer bore of bearing housing. Lip of seal must face outward. See Figure 11. If a press is not available use a plastic or rubber hammer, being careful not to damage or cock seal in the bore.

22. Place back-up washer into seal bore. Place shaft seal onto installation tool (600496) and press seal into seal bore of the housing.
23.Clamp housing in vise, see Figure 1.
24. Place protective bullet (see note below) over shaft. Apply petroleum jelly to inside diameter of dust and shaft seal. You may need a press to install shaft and bearing assembly. Do not distort shaft seal. Damage to this seal will cause leakage.
Note: Note: Bullet (600465), for 1inch dia. shafts, available — by special order. Use tape over other shafts to prevent cutting the seals.
25. Apply petroleum jelly to the 76,0 [3.00] diameter seal. Install seal into the bearing housing.
26. Alignment studs can be very helpful in reassembly of the motor. See special tool listing page 2. If you use studs, install 2 studs diagonally opposed in the bearing housing.

27. Install the shaft face seal in the wear plate as shown in Figure 11. Do not distort seal.
28. Install the wear plate, see Figure 11.
29. Apply a light film of petroleum jelly to the 76,0 [3.00] diameter seal and install seal in the wear plate.
30. Install the drive into the output shaft.
31. Align the notch on the outside of the Geroler with the notch on the wear plate. Install the Geroler against
the wear plate. Be sure to retain the rollers in the outer ring if they are loose.
32. Install the valve drive in the Geroler.
Note: Installation at this time involves 3 steps in the timing of the motor. Timing determines the direction of rotation of the output shaft.

Timing parts include:
1. Geroler
2. Valve Drive
3. Valve Plate
4. Valve

Timing Step # 1 — Locate the largest open pocket in the
Geroler and mark it on the outside edge of the Geroler.
33. Apply a light film of petroleum jelly to the 76,0 [3.00]
diameter seal. Install seal in groove of valve plate.



34. Align the notch on the outside of the valve plate with
the notch on the Geroler as shown in Figure 12.
Timing Step # 2 — Locate the slot opening in the valve
plate which is in line with the largest open pocket of
the Geroler.
Timing Step # 3 — Locate any one of the side openings of
the valve and align this opening with the open slot of the
valve plate that is in line with the largest open pocket of the
Geroler. Install the valve by rotating it clockwise until the
spine teeth engage (1/2 spine tooth max.). This will provide
the proper rotation when pressurized as shown in Figure 13.

35. Install 2 springs and 2 pins in the holes located in the
bore of the valve housing, as shown in Figure 14.
36. Apply a light film of petroleum jelly to the 76,0 [3.00]
diameter seal. Install seal in the valve housing.
37. Apply petroleum jelly to inner and outer face seals.
Install seals on balance ring as shown in Figure 15.
