C50 MANUAL TRANSAXLE: OUTPUT SHAFT: REASSEMBLY

REASSEMBLY

1. INSTALL REVERSE GEAR
(a) Coat the reverse gear with gear oil and install it onto the No. 1 transmission clutch hub.
NOTE: Orient the reverse gear and No. 1 transmission clutch hub correctly.

(b) Install the 3 synchromesh shifting key springs and 3 synchromesh keys onto the No. 1 transmission clutch hub.

2. INSTALL 1ST GEAR THRUST WASHER PIN OR BALL
(a) Coat the 1st gear thrust washer pin or ball with MP grease, and install it onto the output shaft.

3. INSTALL 1ST GEAR THRUST WASHER
(a) Coat the 1st gear thrust washer with gear oil and install it onto the output shaft.

4. INSTALL 1ST GEAR NEEDLE ROLLER BEARING
(a) Coat the 1st gear needle roller bearing with gear oil and install it onto the output shaft.

5. INSTALL 1ST GEAR
(a) Coat the 1st gear with gear oil and install it onto the output shaft.

6. INSTALL NO. 1 SYNCHRONIZER RING (FOR 1ST GEAR)
(a) Coat the No. 1 synchronizer ring with gear oil and install it onto the 1st gear.
7. INSTALL NO. 1 TRANSMISSION CLUTCH HUB

(a) Using SST and a press, install the No. 1 transmission clutch hub onto the output shaft.
SST: 09316-60011
09316-00031
HINT:
- The 1st gear can be turned.
- While checking that the 1st gear thrust washer pin or ball is inserted into the groove of the 1st gear thrust washer, press and fit the No. 1 clutch hub.

(b) Select a snap ring that will allow minimum axial play.
Standard clearance:
0.1 mm (0.039 in.) or less
Snap ring thickness:

(c) Using a brass bar and a hammer, install the snap ring onto the output shaft.
NOTE: Do not damage the journal surface of the output shaft.

8. INSTALL 2ND GEAR NEEDLE ROLLER BEARING
(a) Coat the 2nd gear needle roller bearing and 2nd gear bearing spacer with gear oil, and install them onto the output shaft.

9. INSTALL NO. 1 SYNCHRONIZER RING (FOR 2ND GEAR)
(a) Coat the No. 1 synchronizer ring with gear oil and install it onto the 2nd gear.

10. INSTALL 2ND GEAR
(a) Coat the 2nd gear with gear oil and install it onto the output shaft.

11. INSTALL 3RD DRIVEN GEAR
(a) Using SST and a press, install the 3rd driven gear onto the output shaft.
SST: 09316-60011
09316-00031

12. INSTALL OUTPUT GEAR SPACER
(a) Install the output gear spacer onto the output shaft.

13. INSTALL 4TH DRIVEN GEAR
(a) Using SST and a press, install the 4th driven gear onto the output shaft.
SST: 09612-22011

14. INSTALL OUTPUT SHAFT REAR BEARING
(a) Using SST and a press, install the output shaft rear bearing onto the output shaft.
SST: 09612-22011

15. INSPECT 2ND GEAR RADIAL CLEARANCE
(a) Using a dial gauge, measure the 2nd gear radial clearance between the gear and shaft.
Standard clearance:
KOYO made
0.015 to 0.058 mm (0.0006 to 0.0023 in.)
NSK made
0.015 to 0.056 mm (0.0006 to 0.0022 in.)
Maximum clearance:
KOYO made
0.058 mm (0.0023 in.)
NSK made
0.056 mm (0.0022 in.)
If the clearance exceeds the maximum, replace the 2nd gear or 2nd gear needle roller bearing.

16. INSPECT 1ST GEAR RADIAL CLEARANCE
(a) Using a dial gauge, measure the 1st gear radial clearance between the gear and shaft.
Standard clearance:
KOYO made
0.015 to 0.058 mm (0.0006 to 0.0023 in.)
NSK made
0.015 to 0.056 mm (0.0006 to 0.0022 in.)
Maximum clearance:
KOYO made
0.058 mm (0.0023 in.)
NSK made
0.056 mm (0.0022 in.)
If the clearance exceeds the maximum, replace the 1st gear or 1st gear needle roller bearing.

17. INSPECT 2ND GEAR THRUST CLEARANCE
(a) Using a dial gauge, measure the 2nd gear thrust clearance.
Standard clearance:
0.10 to 0.55 mm (0.0039 to 0.0217 in.)
Maximum clearance:
0.55 mm (0.0217 in.)
If the clearance exceeds the maximum, replace the No. 1 transmission clutch hub, 2nd gear or 3rd driven gear.

18. INSPECT 1ST GEAR THRUST CLEARANCE
(a) Using a feeler gauge, measure the 1st gear thrust clearance.
Standard clearance:
0.10 to 0.40 mm (0.0039 to 0.0157 in.)
Maximum clearance:
0.40 mm (0.0157 in.)
If the clearance exceeds the maximum, replace the 1st gear thrust washer, 1st gear or No. 1 transmission clutch hub.
