Flywheel Inspection
Inspection
NOTE:
Do not clean the dual mass flywheel with compressed air.
NOTE:
Do not clean the dual mass flywheel with any kind of fluid, use a dry cloth only or damage to the dual mass flywheel may occur.
NOTE:
Do not clean the gap between the primary and secondary mass. Only clean the bolt connection surface and the clutch surface or damage to the dual mass flywheel may occur.
NOTE:
The dual mass flywheel cannot be machined.
- 1.NOTE: The dual mass flywheel should be replaced if it has been scored by the clutch or if it has large cracks. Minor heat cracks and heat discoloration do not effect the function of the dual mass flywheel. The dual mass flywheel can be re-used if it has minor heat cracks or heat discoloration.
Inspect the clutch contact surface for damage.
- 1.
If large cracks or scoring are found on the clutch contact surface, install a new dual mass flywheel. Refer to: ENGINE - 1.6L ECOBOOST (132kW/180PS) - SIGMA
- 2.
Minor heat cracks on the clutch contact surface is acceptable wear. Do NOT install a new dual mass flywheel.
- 3.
Minor heat scoring on the clutch contact surface is acceptable wear. Do NOT install a new dual mass flywheel.
- 1.
- 2.NOTE: This check should be done at room temperature.NOTE: Move the secondary mass by hand right and left several times before proceeding with the freeplay check.
Place a reference mark on the secondary mass of the dual mass flywheel.
- 3.
Using light hand pressure, rotate the secondary mass clockwise to the end of the freeplay. Place a reference mark on the primary mass of the dual mass flywheel, in line with the reference mark on the secondary mass.
- 4.
Using light hand pressure, rotate the secondary mass counterclockwise to the end of the freeplay. Place a second reference mark on the secondary mass of the dual mass flywheel, in line with the reference mark on the primary mass.
- 5.
Measure the rotational freeplay between the 2 reference marks on the secondary mass of the dual mass flywheel. If the rotational freeplay exceeds 10 mm (0.394 in), install a new dual mass flywheel.
- 6.
Inspect the dual mass flywheel ring gear. If the ring gear is damaged, install a new dual mass flywheel. Refer to: ENGINE - 1.6L ECOBOOST (132kW/180PS) - SIGMA
- 7.
Inspect the dual mass flywheel guide pins. If the guide pins are missing or different lengths, install a new dual mass flywheel. Refer to: ENGINE - 1.6L ECOBOOST (132kW/180PS) - SIGMA
- 8.
Inspect the transmission bell housing for traces of grease. If there is an excessive amount of grease 46.4 mm (1.83 in) from the front edge of the bell housing, install a new dual mass flywheel. Refer to: ENGINE - 1.6L ECOBOOST (132kW/180PS) - SIGMA
