Inspection
2 – 4 brake drive plates
Measure the 2-4 brake drive plate facing thickness at 3
points and calculate the average value.
If the average value is less than the specified limit, the 2-4
brake drive plate must be replaced.

Standard = 2.0 mm (0.079 in)
Limit = 1.8 mm (0.071 in)
Low and reverse brake drive plates
Measure the low and reverse brake drive plate facing
thickness at 3 points and calculate the average value.
If the average value is less than the specified limit, the lo
