Problem
The retainers for the flyweight dowels in the automatic timing advance unit of the governor may fail on certain 3406B Truck Engines. The failures are the result of a peening action by the dowel.
Affected Product
Model Identification Number 3406B 4MG3600 - 14583
Parts Needed
2 - 9Y7450 Retainer 1 - 2W459 Gasket 4 - 1S5440 Dowel
Action Required
Parts Stock Remove all 7W1528 Retainers from parts stock. The 7W1528 Retainers can be identified by their silver color. The new 9Y7450 Retainers are bluish black. Affected Product Check the upper rear corner of the right side of the cylinder block for the marks "5TS". If the marks "5TS" are there the product has already been reworked. If the marks are not there, proceed. Replace the existing retainers and dowels in the automatic timing advance unit of the governor with the new parts. Tighten the 4B2049 Nut, which is inside the adjusting screw, to 2.5 N.m (20 +/- 2 lb in). Put 9S3263 Thread Lock on the 8C9034 Bolts and tighten them to 3.4 N.m (30 lb in). Install a new gasket. Verify that the dynamic timing is correct and stamp "5TS" on the upper rear corner of the right side of the cylinder block. ****** IMAGE: SEBE3808.00001.001 CAPTION: Location Of 7W1528 Retainers And 1S5440 Dowels In Timing Unit
