36) Measure O/D and 2nd coast brake piston stroke.
• Measure dimension "a" from mating surface of transaxle
case to O/D and 2nd coast brake rear plate (1) using
straightedge and micrometer caliper.
• Measure dimension "b" from O/D and 2nd coast brake piston
(2) to rear cover assembly mating surface using straightedge
and micrometer caliper.
• Calculate piston stroke from measured value of dimensions
"a" and "b".
• Piston stroke = "a" – "b"
O/D and 2nd coast brake piston stroke
Standard: 0.65 – 1.05 mm (0.026 – 0.041 in.)
If piston stroke exceeds specification above, inspect and replace
plates and discs.
37) Remove forward and reverse clutch assembly (1).
38) Remove intermediate shaft thrust bearing front race (1),
thrust bearing (2) and rear race (3) from forward and reverse
