I Have a Cummins Isx engine and i changed the gear cover gasket

This answer was rated:

I Have a Cummins Isx engine and i changed the gear cover gasket and now i need a "dummy's guide to cummins isx timing" some step by step instructions easy to understand. I have already purchased the timing kit (the wedges and the pin).

Hello and welcome to Just Answer! I would be more than happy to assist you today.

 

Timing Wedges:

The timing code is located on the engine dataplate.

  • First number - injector wedge
  • Second number - valve wedge.

 

Rotate the crankshaft clockwise until the "insert pin" mark on the outside diameter of engine vibration damper is aligned with the mark on the gear housing.

Insert the pin in the hole in the pin boss.

The green band on the timing pin will be lined up with the surface of the timing pin boss of the block.

The pin is not correctly seated in the crank notch if the green band is either completely visible outside the block, or is not visible at all.

Lock the crankshaft in place with the crankshaft locking pin

 

Make sure the wedges with the proper angles are used and that the wedges are properly seated in their installed position.

Insert the correct timing wedge to lock the injector camshaft. Lightly tap the top of the timing wedge with a mallet to be sure it is properly seated (there is a flat spot on each cam see pic below)

 

pin location and cam wedge below look for flat spot on cam's
