Article 3254 - Camshaft Spacer Incorporated with Camshaft Sprocket

TSB #157 - January 22, 1971
(Car Vehicles Equipped with 390 and 428 V-8 Engines; Truck Vehicles Equipped with 330, 360, 361, 390 and 391 V-8 Engines)


Beginning with Job No. 1, 1969, the loose camshaft spacer was eliminated on subject models. The spacer is now incorporated with the camshaft sprocket. The new sprocket is released for service for prior models. Be sure that when using the new sprocket no spacer is installed. Applicable shop manuals should be revised to reflect the above information. See Figure 8 for the types of camshaft sprockets.
