Engine Flywheel Cleaning and Inspection

Engine Flywheel Cleaning and Inspection





Note:
In order to maintain the proper component balance, contact surface taper, and heat transfer, manual transmission flywheels are NOT to be machined.

Inspect the dual-mass manual transmission flywheel for the following conditions:

* Pitted surface (1)

* Grooved or scored surface (2)

* Rusted surface (3)

* Damaged ring gear teeth (4)

* Loose or improperly positioned ring gear

The ring gear has an interference fit onto the flywheel and should be positioned completely against the flange of the flywheel.

* Missing, bent or damaged pressure plate locating pins

* The flywheel friction disc contact surface is tapered for improved disc contact. If using a straight edge to determine surface wear, the technician may note less material or a taper to the inner or ID area. This condition is considered normal and not a determining factor when replacing the flywheel.
