REMOVAL
NOTE
Leave the transmission case in the frame unless the case itself requires replacement. For ease of illustration, photographs show the case removed.
WARNING
To prevent accidental vehicle start-up, which could cause death or serious injury, disconnect negative (-) battery cable before proceeding. (00048a)
NOTE
While the two threaded holes at the top of the flange are used for mounting of the drill plate, the fork shaft hole (center thru hole) is used as the pilot for the drill bits.
Detailed instructions on removing the main drive gear and bearing can be found in the 2005 Touring Model Service Manual (Part Number 99483-05), Section 7.7 MAIN DRIVE GEAR/ BEARING
The front dowel pin may be stuck in the side door after removal. If this occurs, remove the dowel pin from the side door and install it back into the transmission case.

    9. Remove the drum support blocks and shift drum. Remove the drum support block dowels from deck of transmission case.
    10. Remove the fork shaft and shifter fork assemblies.
    11. Remove the bearing inner race from the transmission mainshaft.
    12. Remove the transmission side door and the mainshaft/ countershaft assembly.
    13. Remove the shifter shaft assembly and shifter seal.
    14. Remove the main drive gear and bearing.
    15. Remove the countershaft needle bearing.
    2. NOTE
    While the two threaded holes at the top of the flange are used for mounting of the drill plate, the fork shaft hole (center thru hole) is used as the pilot for the drill bits.
  2. Using masking tape, cover all the side door flange holes in the transmission case with the exception of the top three.
  3. From inside the transmission case, tape over all bores as follows:
  • Vehicle speed sensor and mounting screw bores
  • Transmission top cover and shift drum support block screw bores
  • Transmission drain hole bore
  • Main drive gear bearing bore
  • Countershaft needle bearing bore
  • Fork shaft bore
  • Shifter shaft bore
NOTE
Be sure drill plate is properly oriented. Improper orientation will result in damage that requires replacement of the transmission case.
1. See Figure 1. Obtain the drill plate (Part Number 35155-03) provided in kit and fasten to top of side door flange using old and new vehicle speed sensor mounting screws.
2. Spread one or two clean shop cloths inside the transmission case to catch the metal shavings and debris.
CAUTION
Always wear proper eye protection when drilling or grinding. Flying debris could cause serious eye injury. (00402e)
3. Starting with a 3/8 inch drill bit, alternately use progressively larger bits to enlarge the fork shaft hole. Finish the drilling operation with a 3/4 inch drill bit.
4. Remove all remaining material up to the edge of the drill plate with a die grinder or similar tool.
5. Using emery cloth, steel wool, or a fine tooth file, remove any burrs or ridges that may exist from the drilling or cutting operation.
NOTE
Abrasive particles can damage machined surfaces and result in premature failure.
6. Carefully pull out shop cloths from inside the transmission case. Exercise care to keep any debris captured by the cloths from falling into the transmission case.
7. Place drain pan beneath transmission case and remove tape from drain hole. Thoroughly flush the transmission case with a non-volatile cleaning solution or solvent to remove any metal shavings, dust or debris that might remain. For best results, use a squirt bottle to direct a stream of solvent through the transmission top cover opening. Repeat procedure as necessary draining excess solvent through the drain hole.
8. Using low pressure compressed air, thoroughly blow out all solvent.
9. Using a clean lightly oiled cloth, thoroughly wipe the inside of the transmission case. Repeat this step with a new cloth until the cloth comes out clean.
10. Carefully inspect the transmission case for any metal shavings or debris. Repeat Steps 10 through 12 if any debris is found.
11. Remove the masking tape to uncover remaining holes and bores.
12. Thoroughly inspect each bore for any metal shavings, dust or debris. Alternately direct compressed air into each bore to be certain that it is clean and dry.
INSTALLATION
NOTE
Detailed instructions on installing the main drive gear and bearing can be found in the 2005 Touring Model Service Manual (Part Number 99483-05), Section 7.7 MAIN DRIVE GEAR/ BEARING
Prelube all bearings and shafts with clean transmission lubricant prior to installation.
  1. Using the appropriate service manual, proceed as follows:
    1. Install the countershaft needle bearing.
    2. Install the main drive gear and bearing.
    3. Install the new shifter seal. Install shifter shaft assembly from inside the transmission case. Install new shifter seal washer and new retaining ring.
    2. NOTE
    Leave the shrink wrap on the mainshaft until side door installation is complete. Installation of the side door with the shrink wrap removed may result in damage to the main drive gear seal.
    Be sure to remove the plastic cap and cable strap from the mainshaft before side door installation. Blow away any styrofoam bits or other packaging material that might be clinging to gears or splines.
  2. Install the transmission side door and mainshaft/countershaft assembly as follows:
    1. Hang new side door gasket on dowels in side door flange of transmission case.
    2. Start side door and mainshaft/countershaft assembly into transmission case, but stop so that all gears remain on the outboard side.
    3. Note that there are three shifter forks, each of which are stamped for easy identification. Set aside the 5- 6 shifter fork, the 3-4 shifter fork and the 1-2 shifter fork in that order.
    4. Install the 5-6 shifter fork into the shift ring outboard of the 6th gear on the mainshaft (shift ring closest to the main drive gear).
    5. Install the 3-4 shifter fork into the shift ring between the 4th and 3rd gears on the mainshaft (shift ring closest to the side door). Be sure the dogs on the shift ring are engaged with mainshaft 3rd gear and then rotate shifter fork toward the countershaft until the slot in the fork engages the edge of the shift ring between 1st and 2nd gears on the countershaft. This engagement is necessary to obtain the proper clearance for side door installation.
    6. Slide side door assembly further into transmission case stopping about one inch before mating flanges make contact.
    7. Start fork shaft through hole in side door.
    8. Through the transmission top cover opening, install the 1-2 shifter fork into the shift ring between 1st and 2nd gears on the countershaft. For proper clearance, be sure the dogs on the 3-4 shift ring (closest to side door on the mainshaft) are fully engaged with mainshaft 4th gear.
    9. Slide fork shaft through holes in shifter forks and then fully install side door. Be sure that end of fork shaft engages blind hole on left side of transmission case.
    10. Install fork shaft set screw in transmission side door. Tighten screw until the shaft has minimum endplay, but still rotates freely.
    11. Install new side door plug into side door.
    12. Remove shrink wrap from the mainshaft.
NOTE
The 2005 Touring Models Service manual (Part Number 99483-05) includes detailed instructions on installing the mainshaft oil seal, quad seal, spacer sleeve, sprocket and sprocket nut in Section 7.7, MAIN DRIVE GEAR/BEARING .
13. Using the appropriate service manual, proceed as follows:
a. Install four new drum support block dowels in deck of transmission case. Orient the dowels so that the split line is aligned left to right. Install new drum support blocks with new shift drum.
b. Rotating output shaft by hand, shift through all six gears to verify proper operation. Input shaft may need to be rocked back and forth to get all gears to shift.
c. Install the mainshaft oil seal, quad seal, spacer sleeve/sprocket spacer, sprocket, and sprocket nut.
d. Install the new bearing inner race onto the transmission mainshaft.
e. Install the transmission top cover with new gasket.
f. Install the starter.
g. Install the primary chaincase and starter jackshaft assembly. Install the clutch assembly, primary chain, and compensating sprocket components. Install the primary chaincase cover.
h. Install drain plug and fill the primary chaincase with the recommended lubricants.
