RJ-1222-0

For the starter systems in big shuttle buses, hardness of the flywheel ring gear is not sufficient and length of the wire in the activation circuit for the starter magnetic switch is not adequate. For these reasons, the starter pinion and the flywheel ring gear can collide and interfere with each other when starting the engine, and the edges of the gear teeth may be damaged or broken from the wrong meshing. If this occurs, it becomes difficult or impossible to start the engine, and repeating engine starting operations could cause a fire in the worst case.

Case Number: 
RJ-1222-0

Make/model:

Issued: 
Wed, 2004-09-15
Component: 
engine (flywheel ring gear)
Affected: 
2 052
Correction: 
The starter assembly should be replaced with the factory approved replacement unit (including the starter relay). If the vehicle does not have the delayed relays installed, the delayed relay should be additionally installed. If the vehicle does not have the factory approved replacement flywheel ring gear installed yet, the flywheel ring gear should be replaced with the factory approved replacement unit. If the vehicle already has the factory approved replacement flywheel ring gear installed, the gear should be inspected for surface damage, and the damaged gear should be replaced with a new one.
