Setting top center compression position
(1) Temporary pointer
(2) Dial indicator
Fasten a temporary pointer (1) to the cover of the timing case. Put the tip of the pointer close to the outer edge of the crankshaft pulley or the damper.
Remove the rocker cover.
Rotate the crankshaft in a clockwise direction when you face the front of the engine. Rotate the crankshaft until the pushrod for the inlet valve of the rear cylinder begins to lift the rocker lever.
Remove the spring clip and the spacer from the front of the rocker shaft. Release the fasteners of the two front pedestals of the rocker shaft. Remove the front rocker lever. Tighten the fasteners of the pedestals on the rocker shaft.
Remove the valve springs from the front valve.Note: Place a suitable collar near the top of the valve to hold the valve if the crankshaft is rotated too far. Use care in rotating the crankshaft. The number 1 inlet valve will be held in position on top of the piston. If the crankshaft is not properly positioned, the valve may fall from the cylinder head.
Allow the valve to be held by the top of the piston.
Fasten a dial indicator (2) to the cylinder head. The contact of the dial indicator must be in contact with the top of the valve stem. The dial indicator must indicate a reading which is greater than zero. Slowly rotate the crankshaft in a clockwise direction until the clockwise movement of the dial indicator pointer stops.
Make a suitable temporary mark on the crankshaft pulley or the damper to align the mark with the temporary pointer. Continue to rotate the crankshaft in a clockwise direction until the dial indicator pointer barely begins to move in a counterclockwise direction. Make another temporary mark on the pulley or the damper to align the mark with the temporary pointer. Mark the center point between the two marks on the pulley or the damper. Remove the other two marks.
Rotate the crankshaft by approximately 45 degrees in a counterclockwise direction when you face the engine from the front. Then rotate the crankshaft in a clockwise direction until the mark on the pulley or the damper is aligned with the pointer. Number 1 piston is now at the top center on the compression stroke.Set The Top Center Position By Reverse Pin Timing On Type 2 Engines and 7BJ Engines

150-3993 Timing Pin(1) 1
(1) 150-3993 Timing Pin is for (Delphi) and (Stanadyne) fuel injection pumps.The timing position that was set at the factory is used to set the engine at the top center on the number 1 cylinder of the compression stroke before the fuel injection pump is removed.

Timing gear and hub of the Stanadyne and Delphi fuel injection pump
(1) Timing pin
(2) Torx screws
(3) Hub nut
(4) Hole in the pump body
(5) Slot for the timing gear
(6) Hub slotNote: Do not remove the hub nut (3) from the shaft of the fuel injection pump. The hub of the fuel injection pump is installed on the shaft of the pump in the factory to ensure that the fuel injection pump is in the correct position for timing. If the hub is removed, the hub will need to be accurately installed to the shaft of the pump by the use of special equipment. Contact your Caterpillar Dealer for repairs to the fuel injection pump.Note: Do not loosen the torx screws (2). If the torx screws are loosened and the timing plate is moved, the timing position that is set at the factory will be lost. If the torx screws are loosened, the engine must be set to top center of the number 1 engine cylinder on the compression stroke before the torx screws are tightened.
Remove the water pump. Removal of the cover for the gear of the fuel injection pump on some earlier Type 2 engines may be necessary.
Rotate the crankshaft in a clockwise direction until the inlet valve on the number 1 cylinder closes. Slowly rotate the crankshaft until the slot for the timing gear (5) and the hub slot (6) are aligned with the hole in the pump body (4).Note: The position of the slot for the timing gear, the hub slot, and the hole in the pump body is on the bottom of the fuel injection pump. The slot is for inserting the timing pin. The position of the slot is for the Stanadyne and the Delphi fuel injection pump.
Insert the timing pin (1) through the timing gear and the hub slot. Push the timing pin into the hole of the pump body as far as possible. When the pin is inserted all the way, the engine is at the top center of the number 1 cylinder on the compression stroke. No resistance should be felt when the timing pin is inserted into the hole of the pump body (4). The pin should be inserted all the way into the hole of the pump body.Engine Timing Gears
Illustration 4 g06273572
Engine timing gears
(1) Timing gear for the fuel injection pump
(2) Timing gear for the camshaft
(3) Timing gear for the crankshaftNote: Damage to the timing case can occur if the following event occurs: the crankshaft (3) is rotated when the fuel injection pump is removed from the engine. If the crankshaft needs to be rotated, the fuel injection pump must be installed and the fasteners for the gear tightened.Perform the following functions after the fuel injection pump has been removed and the crankshaft has been rotated:
Remove the timing case cover.
Aligning the timing marks of all the timing gears will approximately set the top center of the number 1 cylinder on the compression stroke.
Insert the timing pin.Set The Top Center Position By The Alternate Method
