Disassembly
Cleanliness is extremely important when repairing a hydraulic motor.
Work in a clean area. Before disconnecting the lines, clean port area of
motor thoroughly. Use a wire brush to remove foreign material and
debris from exterior joints of motor. Check shaft and keyway, use 600
grit paper/cloth to remove all nicks, burrs, and sharp edges that might
damage the shaft seals when installing retainer on shaft and bearing
assembly. Before starting disassembly procedures, drain oil from
inside of motor.
1 Place motor in a vise with output shaft down. Clamp across edge
of bearing housing not on housing (see Figure 1). Excessive clamping
pressure on housing will cause distortion. When clamping, use some
protective device on vise, such as special soft jaws, pieces of hard
rubber or board.
Although not all drawings show the motor in a vise, we recommend
that you keep the motor in the vise during disassembly. Follow the
clamping procedures explained throughout the manual.
2 Remove 4 bolts (or nuts for earlier models) from motor. Remove
studs (earlier models) as shown in step 16.
3 Lift valve housing straight up. If done carefully, the springs and
balance ring subassembly will remain on valve for easy removal.
4 Carefully remove the following from the valve housing:
1 seal, 92,3 mm [3.63 inch] I.D.
1 seal, 7,6 mm [.30 inch] I.D.
2 check valve plug assemblies (plug, seal, spring, ball) 1 plug (case
drain) with seal.
5 Remove 3 balance ring springs.
6 Remove balance ring subassembly.
7 Remove inner and outer face seals from the balance ring.
8 Lift off valve.
9 Remove valve plate.
10 Remove 95,0 mm [3.74 inch] I.D. seal from valve plate
(see Figure 5).
11 Remove valve drive (see Figure 5).
