19) Measure the clearance of O/D brake (B0) in the following
manner.
Blow compressed air into hole (4) shown in figure to activate
1st & 2nd brake (B1) piston, then measure the distance
between the top of O/D brake (B0) plate and the transmis-
sion case – rear cover mating surface.
Call this value (A).
((A) = The value on vernier caliper – width of straight edge )
Measure the distance from top of O/D brake (B0) piston (on
rear cover) to rear cover – transmission case mating surface.
Call this value (B).
Clearance = (A) – (B) + 0.4
