49.5.

Take the average of the 3 readings and adjust the shims so that the average measurement corresponds to the following readings:

•	The transaxle condition of the old clutch housing, if greater than 49 900 kilometers (31,000 miles) with old differential bearings, has a nominal value of 0.2 mm (0.008 in).

•	The transaxle condition of the old clutch housing, if greater than 49 900 kilometers (31,000 miles) with NEW differential bearings, has a nominal value of 0.3 mm (0.012 in).

•	The transaxle condition of the new clutch housing with new differential bearings has a nominal value of 0.35 mm (0.014 in).

50. Adjust the shims using the following information:

•	More shims equals increased preload.

•	Less shims equals decreased preload.

•	Shims are available in 0.10 mm, 0.15 mm, 0.30 mm, and 0.5 mm thicknesses.

Notice: Do not forget to remove the milled bearing race. Leaving it in will damage the transaxle.

51. Remove the 10 kg weight, differential bearing retainer, and 87 92 137 .




Important: The differential bearing retainer will not be torqued to specification until the final output shaft preload is set. If the differential bearing retainer is torqued down at this point, it will interfere with the final output shaft measurements.

Important: Make sure that the transaxle is in NEUTRAL.

54. Measure the input shaft bearing pre-load.

54.1.

Remove tool 87 91 428 from the hose.

54.2.

Install a 3/8 in. drive - 16 mm (0.6 in) deep well socket into one end of the hose.

54.3.

Insert the other end over the input shaft as shown.

54.4.

Install the J 7754-C , or equivalent, to the socket and rotate clockwise several rotations at an even speed.

54.5.

Read the average value on the torque wrench during rotations. The torque should be between 0.1-0.3 N·m (1-3 lb in).

If the torque is higher or varies greatly while rotating the input shaft, there may be contamination in the bearings. The transaxle should be disassembled to determine the cause of excessive torque.





Important: Ensure that the drill is spinning in a clockwise direction. The 87 92 053 will unravel if the drill is spinning in the wrong direction.

Important: Ensure that the 87 92 053 does not damage the dial indicator when spinning the output shaft.

Important: The measurement taken in this step must be in millimeters. If the measurement is in inches, multiply it by 25.4 to convert to millimeters.

55. Measure the output shaft end play.

55.1.

Turn the transaxle back to the vertical position.

55.2.

Place the dial indicator tip on the 5th driven gear as shown.

55.9.

Remove all tools.




56. Engage the 1st gear on the transaxle and engage the 5th gear by pressing down the 5th gear synchronizer sleeve.



57. Install the 5th gear synchronizer sleeve.



58. Install the 87 92 061 on the output shaft nut.
59. Calculate the number of line that the 87 92 061 must be turned to tighten the output shaft nut by doing the following:

59.1.

Add the output shaft end play value that was determined in a previous step with the nominal value from the list below. Ensure that the output shaft end play is in millimeters or has been converted to millimeters.

59.2.

Multiply the sum found in the previous step by 100.

59.3.

With a marker, place a mark on the gear tooth corresponding to the line on the socket that matches the number calculated. This is the number of lines that the 87 92 061 must be turned.

Example: The output shaft end play reading found previously is 0.38 mm + nominal value 0.08 mm = 0.46 mm. Multiply 0.46 by 100 = 46. This is the number of lines that the 87 92 061 must be turned.

•	The transaxle condition of the old clutch housing, if greater than 49 900 kilometers (31,000 miles) with the old differential bearing greater than 49 900 kilometers (31,000 miles), has a nominal value of 0 mm (0 in).

•	The transaxle condition of the old clutch housing, if less than 49 900 kilometers (31,000 miles) with the old output shaft bearing less than 49 900 kilometers (31,000 miles), has a nominal value of 0.03 mm (0.0012 in).

•	The transaxle condition of the old clutch housing, if less than 49 900 kilometers (31,000 miles) with a new output shaft bearing, has a nominal value of 0.8 mm (0.003 in).

•	The transaxle condition of the new clutch housing with a new output shaft has a nominal value of 0.15 mm (0.006 in).




60. Tighten the output shaft nut in 2-3 stages until the zero (0) on the socket is at the marked gear tooth.
61. Before taking a more precise measurement of the output shaft bearing preload, make sure the following condition are true:

•	The input shaft bearing end play is 0.09-0.15 mm (0.003-0.006 in).

•	The differential bearing retainer is installed but not tight. The end play is 0.15 mm (0.006 in).

62. Turn the transaxle to the horizontal, in car, position. Disengage the 1st gear and remove the 5th gear synchronizer sleeve.



63. Check the input shaft and output shaft bearing preload.

63.1.

Ensure that the transaxle is in Neutral.

63.2.

Install the J 7754-C , or equivalent, on the output shaft nut.

63.3.

Rotate the wrench clockwise at an even speed.

63.4.

Read the average value during rotation.

63.5.

Subtract the average value from the input shaft, taken in step 43, from the average value of the output shaft. The calculated preload is the measurement of the output shafts turning torque, normally 0.75-0.25 N·m. (6.75-2.25 lb in).

Example:

Output Shaft Reading: 1.10 N·m (10 lb in)

Input Shaft Reading: 0.30 N·m (2.7 lb in)

Preload: 1.10-0.30 = 0.80 N·m (7.2 lb in)

If the average torque is less than 0.5 N·m (4.5 lb in)

Cause: Bearings are not sufficiently tight.

Correction: Tighten the output shaft nut by 2 lines on the 87 92 061 . Take another measurement. Repeat the process until the correct torque is reached.

If the average torque varies greatly:

Cause: Contamination in the bearings or faulty synchronizer blocking rings.

Correction: Disassemble the transaxle, inspect the components, and repair as necessary.

If the average torque is higher than 1.0 N·m (9 lb in)

Cause: Bearings are too tight or contamination in the bearings.

Correction: Install a new crush sleeve in the transaxle and reset the bearing preloads.




64. Lock the output shaft nut using a chisel and a hammer.
65. Turn the transaxle to the vertical position. Put the transaxle in 3rd gear.

34. Verify that the shifter arms can engage all gears. Refer to Shift Control Lever and Selector Control Lever Position/Rotation Specifications .




Notice: Do not compress the crush sleeve when installing the output shaft bearing . Any compression of the sleeve done other than by tightening the output shaft nut will require disassembly of the transaxle and replacement of the crush sleeve.

35. Lubricate and install the output shaft bearing using the 87 91 261 . Tighten the 87 91 261 until a solid stop is felt. Do not compress the sleeve.




Important: Ensure that the 3 machine cutouts on the 5th driven gear are facing away from the bearing.

36. Install the 5th driven gear onto the output shaft. Tap down with the 78 41 067 far enough to allow installation of the 87 91 261 .
37. Install the 87 91 261 and tighten the tool until the 5th driven gear is against the output shaft bearing. Install a new output shaft nut, but do not tighten.




Important: Carefully tap the input shaft with a plastic hammer from the engine side so the input shaft bearing race is against the input shaft bearing retainer.

Important: If a dial indicator with a magnetic base is used, it will not work with an aluminum case. Locking C-clamp pliers can be used to hold the indicator base to the transaxle case.

38. Install the 87 91 428 to the input shaft and install the J 8001 , or equivalent, on the input shaft bearing inner race. Attach a drill to the 87 91 428 and spin the transaxle to seat the bearings. Turn the transaxle input shaft about 20 revolutions while pushing and pulling on the drill. While turning, measure the axial play on the dial indicator. Axial play should be between 0.09-0.15 mm (0.004-0.006 in).
39. Adjust axial play as needed by adding or removing shims under the input shaft bearing retainer.




Important: Make sure that the center wing-headed bolt is backed out completely before installing the support tool.

40. Install the J 44362 on the transaxle as shown. Turn the center wingheaded bolt until contact is made with the input shaft, then turn an additional quarter to a half turn.



41. Lubricate and install the 5th drive gear bearing, 5th drive gear, 5th gear blocking ring, 5th gear leaf springs and blocking ring spring.




Important: The tangs on the blocking rings must fit in the hub gaps. Ensure that the blocking ring spring is engaged on the blocking ring and does not get pinched between the hub and the blocking ring.

42. Carefully tap down the 5th synchronizer hub onto the input shaft splines using the 87 91 311 and a hammer.




Important: The 5th gear synchronizer sleeve can only be placed on the hub when the tall teeth on the sleeve are aligned with the deep tooth grooves on the hub.

43. Install the 5th gear synchronizer sleeve. Reference the sleeve alignment mark made during disassembly.



44. Loosely install the output shaft nut.

Important: Do not pry under the gear teeth. Make sure the screwdriver is as far past the gear teeth as possible.

45. Install the J 8001 , or equivalent, on top of the 5th driven gear. Engage the 1st gear on the transaxle and engage the 5th gear by pressing down the 5th gear synchronizer sleeve. Install a bolt in the case as shown so that you are not prying against the rear cover sealing surface. Measure the output shaft end play by prying up on the 5th driven gear and watching the dial indicator.

Tighten
Tighten the output shaft nut until end play is between 0.06-0.05 mm (0.002-0.002 in).




46. Disengage the 1st gear and remove the 5th gear synchronizer sleeve.



47. Check and adjust the preload of the differential bearings as follows:

47.1.

Install the 87 92 137 in place of the left differential bearing race.

47.2.

Install about 2 mm of shims on top of the ground bearing race.

47.3.

Remove the O-ring from the differential bearing retainer and install without any fasteners.





Important: Make sure the drill is spinning in a clockwise direction. The 87 92 053 will unravel if the drill is spinning in the wrong direction.

48. Measure the differential bearing pre-load.

48.1.

Place the 87 92 095 on top of the differential bearing retainer.

48.2.

Install the 87 92 053 on the output shaft.

48.3.

Use a drill to rotate the differential at least 20 revolutions.

48.4.

Use a feeler gage and measure between the transaxle case and differential bearing retainer in 3 different places.

48.5.

Take the average of the 3 readings and adjust the shims so that the average measurement corresponds to the following readings:

•	The transaxle condition of the old clutch housing, if greater than 49 900 kilometers (31,000 miles) with old differential bearings, has a nominal value of 0.2 mm (0.008 in).

•	The transaxle condition of the old clutch housing, if greater than 49 900 kilometers (31,000 miles) with NEW differential bearings, has a nominal value of 0.3 mm (0.012 in).

•	The transaxle condition of the new clutch housing with new differential bearings has a nominal value of 0.35 mm (0.014 in).

49. Adjust the shims using the following information:

•	More shims equals increased preload.

•	Less shims equals decreased preload.

•	Shims are available in 0.10 mm, 0.15 mm, 0.30 mm, and 0.5 mm thicknesses.

Notice: Do not forget to remove the milled bearing race. Leaving it in will damage the transaxle.

50. Remove the 10 kg weight, differential bearing retainer, and 87 92 137 .




Important: The differential bearing retainer will not be torqued to specification until the final output shaft preload is set. If the differential bearing retainer is torqued down at this point, it will interfere with the final output shaft measurements.

51. Install the differential bearing retainer.

51.1.

Install the differential bearing race and tap down using the 83 90 114 .

51.2.

Install the shim pack determined in the last step.

51.3.

Lubricate the O-ring and install on the differential bearing retainer.

51.4.

51.5.

Tighten the retainer bolts until the retainer is 0.15 mm (0.006 in) from the transaxle case.




52. Turn the transaxle to the horizontal, in car, position.

Important: Ensure that the transaxle is in NEUTRAL.

53. Measure the input shaft bearing preload.

53.1.

Remove tool 87 91 428 from the hose.

53.2.

Install a 3/8 in. drive - 16 mm (0.6 in) deep well socket into one end of the hose.

53.3.

Insert the other end over the input shaft as shown.

53.4.

Install the J 7754-C , or equivalent, to the socket and rotate clockwise several rotations at an even speed.

53.5.

Read the average value on the torque wrench during rotations. The torque should be between 0.1-0.3 N·m (1-3 lb in).

If the torque is higher or varies greatly while rotating the input shaft, there may be contamination in the bearings. The transaxle should be disassembled to determine the cause of excessive torque.





Important: Ensure that the drill is spinning in a clockwise direction. The 87 92 053 will unravel if the drill is spinning in the wrong direction.

Important: Ensure that the 87 92 053 does not damage the dial indicator when spinning the output shaft.

Important: The measurement taken in this step must be in millimeters. If the measurement is in inches, multiply it by 25.4 to convert to millimeters.

54. Measure the output shaft end play.

54.1.

Turn the transaxle back to the vertical position.

54.2.

Place the dial indicator tip on the 5th driven gear as shown.

54.3.

Install the 87 92 053 on the output shaft.

54.4.

Turn the output shaft several revolutions to seat the bearings.

54.5.

Press down on the drill and turn the output shaft for 20 revolutions.

54.6.

Zero the dial indicator.

54.7.

Pull up on the drill and turn for another 20 revolutions.

54.8.

Take a measurement when the reading stabilizes. This output shaft end play measurement will be used in tightening the input shaft nut in a later step. Convert the measurement to millimeters if necessary.

54.9.

Remove all tools.




55. Engage the 1st gear on the transaxle and engage the 5th gear by pressing down the 5th gear synchronizer sleeve.



56. Install the 5th gear synchronizer sleeve.



57. Install the 87 92 061 on the output shaft nut.
58. Calculate the number of line that the 87 92 061 must be turned to tighten the output shaft nut by doing the following:

58.1.

Add the output shaft end play value that was determined in a previous step with the nominal value from the list below. Ensure that the output shaft end play is in millimeters or has been converted to millimeters.

58.2.

Multiply the sum found in the previous step by 100.

58.3.

With a marker, place a mark on the gear tooth corresponding to the line on the socket that matches the number calculated. This is the number of lines that the 87 92 061 must be turned.

Example: The output shaft end play reading found previously is 0.38 mm + nominal value 0.08 mm = 0.46 mm. Multiply 0.46 by 100 = 46. This is the number of lines that the 87 92 061 must be turned.

•	The transaxle condition of the old clutch housing, if greater than 49 900 kilometers (31,000 miles) with the old differential bearing greater than 49 900 kilometers (31,000 miles), has a nominal value of 0 mm (0 in).

•	The transaxle condition of the old clutch housing, if less than 49 900 kilometers (31,000 miles) with the old output shaft bearing less than 49 900 kilometers (31,000 miles), has a nominal value of 0.03 mm (0.0012 in).

•	The transaxle condition of the old clutch housing, if less than 49 900 kilometers (31,000 miles) with a new output shaft bearing, has a nominal value of 0.8 mm (0.003 in).

•	The transaxle condition of the new clutch housing with a new output shaft has a nominal value of 0.15 mm (0.006 in).




59. Tighten the output shaft nut in 2-3 stages until the zero (0) on the socket is at the marked gear tooth.
60. Before taking a more precise measurement of the output shaft bearing preload, make sure the following conditions are true:

•	The input shaft bearing end play is 0.09-0.15 mm (0.003-0.006 in).

•	The differential bearing retainer is installed but not tight. The end play is 0.15 mm (0.006 in).

61. Turn the transaxle to the horizontal, in car, position. Disengage the 1st gear and remove the 5th gear synchronizer sleeve.



62. Check the input shaft and output shaft bearing preload.

62.1.

Ensure that the transaxle is in NEUTRAL.

62.2.

Install the J 7754-C , or equivalent, on the output shaft nut.

62.3.

Rotate the wrench clockwise at an even speed.

62.4.

Read the average value during rotation.

62.5.

Subtract the average value from the input shaft, taken in step 43, from the average value of the output shaft. The calculated preload is the measurement of the output shafts turning torque, normally 0.75-0.25 N·m. (6.64-2.21 lb in).

Example:

Output Shaft Reading: 1.10 N·m (10 lb in)

Input Shaft Reading: 0.30 N·m (2.7 lb in)

Preload: 1.10-0.30 = 0.80 N·m (7.2 lb in)

If the average torque is less than 0.5 N·m (4.5 lb in)

Cause: Bearings are not sufficiently tight.

Correction: Tighten the output shaft nut by 2 lines on the 87 92 061 . Take another measurement. Repeat the process until the correct torque is reached.

If the average torque varies greatly:

Cause: Contamination in the bearings or faulty synchronizer blocking rings.

Correction: Disassemble the transaxle, inspect the components, and repair as necessary.

If the average torque is higher than 1.0 N·m (9 lb in)

Cause: Bearings are too tight or contamination in the bearings.

Correction: Install a new crush sleeve in the transaxle and reset the bearing preloads.




63. Lock the output shaft nut using a chisel and a hammer.
64. Turn the transaxle to the vertical position. Put the transaxle in 3rd gear.

Important: The 5th gear fork and synchronizer sleeve together can only be placed on the hub when the tall teeth on the sleeve are aligned with the deep tooth grooves on the hub.

65. Install the 5th gear fork and synchronizer sleeve together. Reference the sleeve alignment mark made during disassembly.
