The Fuel Injection Pump Sprocket Locking tool (303-1317) is used with special sprocket pulley remover (303-249) and adapter for 303-249 (303-249-01) to press off the high pressure fuel pump from the high pressure fuel pump drive gear sprocket.

The injection pump sprocket locking tool (grey piece) is required to retain the pump timing position and is fitted in a clockwise direction with the bayonet slots located on the aperture lugs.
Having this grey piece in place allows you to remove the H/P pump without disturbing the engine timing and the chain from dropping.

NOTE: For earlier model engines and 2.4L engines you may require the earlier version DM21-1556-0129 (OEM: 303-1151)

PLEASE NOTE: You may need DM11-A1776 for removal of the high pressure pump sprocket (OEM: 303-249).
