4.4.2 Replacing the Buffer Brush
As the buffer brush wears, gets dirty, bristles tangle and break off, it will no longer apply the
oil properly. The buffer brush should be replaced every 1,080,000 feet of travel or when
adjusting the brush pressure doesn’t significantly improve its performance.
NOTE
The buffer brush can be adjusted to help maintain its performance. As the buffer
brush wears, its bristles become thin and tapered and its performance degrades.
Even though a pressure between B and C on the buffer pressure adjusting tool
is achievable, it will not hold as much oil or function as well and should be
replaced.
Tools Needed:
None
Perform the steps below with the machine in the storage position to replace the buffer
brush.
1. Facing the base plate, hold the machine in place by the frame on the right side and
grasp the left end of the buffer brush.
2. Gently slide the buffer brush to the right while slightly pulling the left end out of the
machine. Pull out the left end until it is just clear of the slot in the base plate as
shown in Figure 4- 355 and Figure 4- 366.
3. Pull the buffer brush towards the left to release its right side from the machine.
4. Pull the entire buffer brush out from the machine.
