Balancing mandrel (Flywheel for automatic and manual transmission)

617 589 00 63 00

Rotating device for static balancing

e.g. made by Trebel, D-4030 Ratingen type EO

The engine is fully balanced, that is, the complete engine has been balanced on a balancing machine.

Since in the event of repairs this type of balancing cannot be performed, while on the other hand the balanced condition of the engine should be main­tained as much as possible, a new flywheel must be brought to the same balancing condition as the removed flywheel.

1 Place old and new flywheel one above the other in such a manner that all the bores are in alignment and both coupling surfaces are facing in one direction.

3 Permit balancing mandrel with both flywheels to swing on rotating device to stop.

4 If an unbalance if found, drill as many holes on heavy side of new flywheel as required until the fly­wheels will come to a rest in any position without swinging.

The hole circle dia., the drill dia. and the max. drilling depth must be maintained.
