25. CHECK PISTON STROKE OF OVERDRIVE BRAKE





a) Place SST and dial indicator onto the overdrive brake piston.
SST 09350-30020 (09350-06120)





b) Measure the stroke while applying and releasing compressed air (392 - 785 kPa, 4 - 8 kg-cm2 or 57 - 114 psi).

Piston stroke: 1.75 - 2.05 mm (0.0689 - 0.0807 inch)

If the values are non-standard, inspect the discs.

26. REMOVE FLANGES, PLATES AND DISCS OF OVERDRIVE BRAKE





a) Remove the snap ring.





b) Remove the flange, 5 plates and 5 discs.

27. REMOVE OVERDRIVE SUPPORT ASSEMBLY





a) Remove the 2 bolts holding the overdrive support assembly to the case.





b) Using SST, remove the snap ring.
SST 09350-30020 (09350-07060)





c) Using SST, remove the overdrive support assembly.
SST 09350-30020 (09350-07020)





d) Remove the assembled bearing and races from the overdrive support.

28. CHECK PISTON ROD STROKE OF SECOND COAST BRAKE





a) Using a waterproof pen, place a mark on the second coast brake piston rod.





b) Using SST, measure the stroke while applying and releasing compressed air (392 - 784 kPa, 4 - 8 kg-cm2 or 57 - 114 psi).
SST 09240-00020

Piston rod stroke: 1.0 - 2.0 mm (0.039 - 0.079 inch)

If the values are non-standard, inspect the brake band.

29. REMOVE SECOND COAST BRAKE COVER, PISTON ASSEMBLY AND SPRING





a) Using SST, remove the snap ring.
SST 09350-30020 (09350-07060)





b) Applying compressed air to the oil hole, remove the second cost brake cover, piston assembly and spring.





c) Remove the 2 0-rings from the cover.

b) Remove the thrust washer.





36. CHECK PACK CLEARANCE OF SECOND BRAKE
Using a feeler gauge, measure the clearance between the snap ring and flange.

Clearance: 0.49 - 1.11 mm (0.0193 - 0.0437 inch)

If the values are non-standard, inspect the discs.

37. REMOVE FLANGE, PLATES AND DISCS OF SECOND BRAKE





a) Remove the snap ring.





b) Remove the flange, 5 plates and 5 discs as a set.





38. CHECK PACK CLEARANCE OF FIRST AND REVERSE BRAKE
Using a feeler gauge, measure the clearance between the plate and second brake drum.

Clearance: 0.7 - 1.0 mm (0.028 - 0.039 inch)
