Part 2

31. CHECK PISTON ROD STROKE OF SECOND COAST BRAKE





a) Place a mark on the second coast brake piston rod.





b) Using SST, measure the stroke while applying and releasing compressed air (392 - 785 kPa, 4 - 8 kg-cm2, 57 - 114 psi).
SST 09240-00020

Piston stroke: 1.5 - 3.0 mm (0.059 - 0.118 inch)

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

32. 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 coast brake cover, piston assembly and spring.





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

33. REMOVE DIRECT CLUTCH WITH FORWARD CLUTCH





a) Remove the direct clutch with the forward clutch from the case.





b) Remove the direct clutch from the forward clutch.





c) Remove the assembled bearing and race, thrust washer and race from the forward clutch.

34. REMOVE SECOND COAST BRAKE BAND
a) Remove the E-ring from the pin.





b) Remove the pin from the brake band.





c) Remove the second coast brake from the case.

35. REMOVE FRONT PLANETARY GEAR UNIT





a) Remove the front planetary ring gear from the case.





b) Remove the bearing and race from the front planetary ring gear.





c) Remove the race from the front planetary gear.





d) With wooden blocks under the output shaft, stand the transmission on the output shaft.

36. REMOVE FRONT PLANETARY GEAR





a) Using SST, remove the snap ring.
SST 09350-30029 (09350-07070)

HINT: Pushing the output shaft towards the front makes it easier to remove.

37. REMOVE PLANETARY SUN GEAR WITH NO.1 ONE -WAY CLUTCH
a) Remove the planetary sun gear with No.1 one-way clutch from the case.





b) Remove the thrust washer.





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

Clearance: 0.62 - 1.98 mm (0.0244 - 0.0780 inch)

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

39. REMOVE FLANGE, PLATES AND DISCS OF SECOND BRAKE





a) Remove the snap ring.





b) Remove the flange, plates and discs.





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

Clearance: 0.60 - 1.12 mm (0.0236 - 0.0441 inch)

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





41. REMOVE SECOND BRAKE PISTON SLEEVE
42. REMOVE REAR PLANETARY GEAR WITH SECOND BRAKE DRUM, FIRST AND REVERSE BRAKE PACK AND OUTPUT SHAFT





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





b) Remove the rear planetary gear, second brake drum, first and reverse brake pack and output shaft as an assembly.





c) Remove the assembled thrust bearing and race from the case.





43. REMOVE LEAF SPRING





44. REMOVE BRAKE DRUM GASKET
