REMOVE BRAKE APPLY INDICATORS AND LEFT BRAKE APPLY SHAFT

NOTE

Make sure that the right cover assembly is turned so that the internal side points up.

Outer retaining rings may or may not be on the left brake apply shaft and the right brake apply

cam shaft. These retaining rings are supplied to keep external brake linkage.

You must hold the left brake apply shaft in position with a wooden block or by hand to keep it

from falling out of the end cover after removal of retaining rings and indicator.

1. Put a wooden block under the right cover assembly (Figure 1, Item 5) and another under the left brake apply

shaft (Figure 1, Item 1).

2. Remove four retaining rings (Figure 1, Item 3), two from left brake apply shaft (Figure 1, Item 1) and two

from right brake apply cam shaft (Figure 1, Item 4).

3. Remove two indicators (Figure 1, Item 2), one from left brake apply shaft (Figure 1, Item 1) and one from

right brake apply shaft (Figure 1, Item 4).

CAUTION

Put protective material, such as masking tape, on the splines unless the seal is to be replaced.

If the shaft goes through the seal without protection, the splines on the shaft will cause damage

to the seal.

4. Clean the left brake apply shaft (Figure 1, Item 1) and the right brake apply shaft (Figure 1, Item 4).

5. Put masking tape on splines and on the end of the left brake apply shaft (Figure 1, Item 1) and the right brake

apply shaft (Figure 1, Item 4).

6. Put petrolatum on tape on the left brake apply shaft (Figure 1, Item 1) and also on the right brake apply

shaft (Figure 1, Item 4).
