Section 0 - Engine Disassembly and Assembly - Group 00 Engine Assembly (0-02) M11 Page 0-99 Install the injector push rod (9) between the injector cam- shaft follower and the plunger rod. NOTE: The push rod must be aligned properly to attain a correct reading. Caution: Always use the accessory drive shaft to rotate (bar) the crankshaft for checking the static injection tim- ing. Using any other method will cause an error in the static injection timing or can damage the engine. NOTE: The accessory drive pulley capscrew will need to be installed to rotate the crankshaft.
Determine the piston top dead center (TDC) on the com- pression stroke by rotating the accessory drive shaft in the direction of engine rotation clockwise . The piston is on the compression stroke when both plung- ers move in an upward direction at the same time. TDC is indicated by the maximum clockwise indicator position of the piston travel indicator pointer. Caution: Both indicators must have a travel range of at least 6.35 mm [0.250 inch] or the indicators will be dam- aged. Position the gauge contact tip in the center of the plunger rod and lower the gauge to within 0.63 mm [0.025 inch] of the fully compressed position.
Set the dial indicator over the piston plunger rod to (zero) when the piston plunger rod has reached maximum upward movement TDC.
