“a”: 19.15 mm (0.754 in.)
Pack Clearance Check
1) Install retaining plate and 1st and reverse brake disc set (1) (4 friction discs, 3 friction plates and separator plate (2)) in the transmission case, then install the snap ring.
2) Blow air into oil passage (3) as shown in figure below and measure pack clearance “a”. When measured value is out of specified value range, it is possible that there is air leakage, seizure or worn 1st & reverse brake disc set (1).
Pack clearance
“a”: 0.62 – 1.37 mm (0.024 – 0.054 in.)
