THROUGH 0300185827)
Use the following procedure to install the seal kit.
1.
If not already removed, remove the axle oscillation valve
from the cylinder barrel. The spool of the valve pro-
trudes into the barrel and will damage the spool and
seals if left in place.
2.
Remove snap ring (7) from end.
3.
Remove thrust ring (3) from the same end.
4.
Remove center body (1) from housing (3).
5.
Cut off old seals (2, 4, 5).
6.
Remove proximity switch.
7.
Assemble lip seals (2) in direction shown in Figure 3-56.,
Rotary Coupling Seal Installation (Prior to SN
0300138447).
8.
Reassemble o-ring (4).
9.
Heat cap seals (5) in hydraulic oil for 5 minutes at 300° F
(149° C).
10.
Assemble cap seals over o-rings.
11.
Reinsert center body into housing (lube with hydraulic
oil).
12.
Replace thrust ring and snap ring.
13.
Install proximity switch as shown in Figure 3-63.
