Thrust Washer and Inner Bearing Race Removal
| 1. | Obtain FLYWHEEL SUPPORT FIXTURE (HD-44358), see Figure 2. Install brass jaws or shop towels around the teeth of a vise to prevent tool damage. Clamp the tool in the vise with the round hole topside. | |||||||||||||||
| 2. | Insert the right-side crankshaft end through the hole, resting the flywheel assembly on the fixture. Slide the knurled locating pin down the slot in the tool to engage the crank pin hole. Hand tighten the locating pin. | 
Figure 2. Flywheel Fixture (Part Number HD-44358) | ||||||||||||||
| 3. | Slide the hold-down clamp down the slot to engage the inboard side of the right flywheel half, then hand tighten the knurled nut at the bottom to secure. Repeat this step to secure the hold-down clamp on the opposite side of the flywheel. NOTE For proper clamping force, hold-down clamp must not be tilted. Rotate hex on outboard stud until clamp is level. | |||||||||||||||
| 4. | See Figure 2. Position the WEDGE ATTACHMENT (HD-95637-46A) on the inboard side of the thrust washer, and turn the hex nuts an equal number of turns to draw the halves of the wedge together. | |||||||||||||||
NOTICE Install wedge attachment only so far as necessary to ensure positive contact with bearing inner race. Installing tool with more contact than necessary will result in damage to the flywheel (00500b) | ||||||||||||||||
| 5. | Obtain two 3/8-16 x 6-1/2 inch long bolts and flat washers. Install the flat washers on the bolts. Obtain the bridge, forcing screw and hardened plug from the MAINSHAFT BEARING INNER RACE PULLER/ INSTALLER (HD-34902B). | |||||||||||||||
| 6. | Slide one bolt into the channel on each side of the bridge so that the flat washer is between the bridge and bolt head. Thread the bolts into the wedge attachment an equal number of turns. | |||||||||||||||
| 7. | Sparingly apply graphite lubricant to the threads of the forcing screw to prolong service life and verify smooth operation. Start the forcing screw into the center hole of the bridge. NOTE Failure to use hardened plug may result in damage to forcing screw and/or sprocket shaft. | |||||||||||||||
| 8. | Place the cupped side of the hardened plug against the end of the sprocket shaft. Thread the forcing screw into the bridge until the steel ball at the end of the screw makes firm contact with the hardened plug. |

WARNINGBe sure to follow manufacturer's instructions when using the Robinair Heat Gun or any other radiant heating device. Failure to follow manufacturer's instructions can cause a fire, which could result in death or serious injury. (00379a)
- Always keep hands away from tool tip area and heat shrink attachment.
- Be sure to turn the "ON/OFF" switch to the "OFF" position after use.
| 9. | Using the Robinair Heat Gun (HD-25070), uniformly heat the bearing inner race for about 30 seconds. NOTE To facilitate removal without heat, apply a light penetrating oil to shaft and leading edge of bearing inner race. NOTE Never use both heat and penetrating oil. Use only one or the other. Heat can cause the penetrating oil to ignite resulting in flames or fire. | |||||||||||||||
| 10. | Turn the forcing screw until the thrust washer (and bearing inner race) moves approximately 1/8 inch (3.2 mm). | |||||||||||||||
| 11. | Turn the hex nuts an equal number of turns to separate the halves of the WEDGE ATTACHMENT. |

| 12. | After bottoming the thrust washer on the shaft, reposition the WEDGE ATTACHMENT (HD-95637-46A) on the inboard side of the bearing inner race. Turn the hex nuts an equal number of turns to draw the halves of the wedge together. | |||||||||||||||
NOTICE Install wedge attachment only so far as necessary to ensure positive contact with bearing inner race. Installing tool with more contact than necessary will result in damage to the flywheel (00500b) | ||||||||||||||||
| 13. | Verify that the tool assembly is square, so that the bearing inner race is not cocked during removal. | |||||||||||||||
| 14. | See Figure 3. Using the Robinair Heat Gun (HD-25070), uniformly heat the bearing inner race for about 30 seconds using a circular motion. NOTE To facilitate removal without heat, apply a light penetrating oil to shaft and leading edge of bearing inner race. | |||||||||||||||
| 15. | Turn the forcing screw until the bearing inner race is pulled free of the sprocket shaft. | |||||||||||||||
| 16. | Remove the thrust washer from the sprocket shaft. | |||||||||||||||
| 17. | Discard the bearing inner race and thrust washer. |
