Figure 1.

Fuel Injector.

CAUTION

Rotate engine crankshaft in clockwise direction only. Do not rotate crankshaft in

counterclockwise direction using crankshaft bolt. Crankshaft bolt can loosen and

serious engine damage may result if crankshaft bolt is not securely tightened to

crankshaft.

Manually rotating the engine crankshaft could create ignition and start the engine.

When rotating engine crankshaft in clockwise direction, manually hold the fuel

shut-off control lever, located on the governor cover assembly, in the fuel shut-

off/no fuel position. Visually make sure all fuel injector racks are in the no fuel

position.

When the engine crankshaft is being rotated by helper, the mechanic must visually

monitor the positions of fuel injector rocker arm, two exhaust valve rocker arms

and the three related push rods, which are associated to the fuel injector being

removed.

Manually rotate engine crankshaft in clockwise direction until pressure of fuel injector rocker arm

(Figure 2, Item 3) and two exhaust valve rocker arms (Figure 2, Item 2) are released from fuel injector

plunger follower (Figure 3, Item 4) and exhaust valve stems (Figure 3, Item 5). Make sure fuel injector

rocker arm (Figure 4, Item 3) and exhaust valve rocker arms (Figure 4, Item 2) are fully released and three

push rods (Figure 4, Item 6) are loose, in lowest travel position, and horizontally aligned.
