BME051517301303

## Gears Inspection

1. Inspect the synchronizer cones for wear.

  • If there is any malfunction, replace parts if necessary.

2. Inspect the gear teeth for damage, wear, and cracks.

  • If there is any malfunction, replace parts if necessary.

3. Inspect the synchronizer ring matching teeth for damage and wear.

  • If there is any malfunction, replace the synchronizer ring.

## Synchronizer Ring Inspection

1. Inspect the synchronizer ring teeth for damage, wear, and cracks.

  • If there is any malfunction, replace parts if necessary.

2. Inspect the tapered surface for wear and cracks.

  • If there is any malfunction, replace parts if necessary.

3. Measure the clearance between the synchronizer ring and the side of gear circumferentially using a feeler gauge.

  • If it is less than the minimum specification, replace the synchronizer ring.

  Clearance
  Standard: 1.50 mm {0.059 in}
  Maximum: 0.80 mm {0.031 in}

## Clutch Hub Component Inspection

1. Inspect the clutch hub sleeve and hub operation.

  • If there is any malfunction, replace parts if necessary.

2. Inspect the gear teeth for damage, wear, and cracks.

  • If there is any malfunction, replace parts if necessary.

3. Inspect the synchronizer keys for damage, wear, and cracks.

  • If there is any malfunction, replace parts if necessary.

4. Measure the clearance between the hub sleeve and shift fork.

  • If it exceeds the maximum specification, replace the hub sleeve and shift fork as a set.

  Clearance
  Standard: 0.10-0.45 mm {0.004-0.017 in}
  Maximum: 0.95 mm {0.037 in}

## Secondary Shaft Gear Inspection

1. Inspect the gear contact surface for damage and wear.

  • If there is any malfunction, replace the secondary shaft.

2. Inspect the splines for damage and wear.

  • If there is any malfunction, replace the secondary shaft.

3. Inspect the gear teeth for damage, wear, and cracks.

  • If there is any malfunction, replace the secondary shaft.

4. Inspect the oil passage for clogging.

  • If there is any malfunction, replace the secondary shaft.

5. Measure the shaft gear runout.

  • If it exceeds the maximum specification, replace the secondary shaft.

  Maximum runout
  0.015 mm {0.0006 in}

6. Measure the clearance between the shaft gears and the gears.

  • If not within the specification, replace parts if necessary.
