Fuel Pressure
The 1U-5470 Engine Pressure Group can be used in order to check the engine fuel pressures.

1U-5470 Engine Pressure Group (1) Pressure indicators. (2) Zero adjustment screw. (3) Pressure indicator. (4) Pressure tap. (5) Pressure indicator.This tool group has an indicator that is used to read the pressure in the fuel manifolds. The Special Instruction, SEHS8907 is with the tool group.The fuel pressure regulating valve keeps the pressure in fuel manifolds between 415 to 450 kPa (60 to 65 psi).

Put timing bolt (2) through the timing hole in the flywheel housing. Use the 9S-9082 Engine Turning Tool (4) and a 1/2 inch drive ratchet wrench in order to turn the flywheel in the direction of normal engine rotation. Turn the flywheel until the timing bolt engages with the hole in the flywheel.Note: If the flywheel is turned beyond the point of engagement, the flywheel must be turned in the direction that is opposite of normal engine rotation. Turn the flywheel by approximately 30 degrees. Then turn the flywheel in the direction of normal engine rotation until the timing bolt engages with the threaded hole. This procedure will remove the play from the gears when the No. 1 piston is on top center.
Remove the valve cover for the No. 1 cylinder head.
The inlet and exhaust valves for the No. 1 cylinder are fully closed if No. 1 piston is on the compression stroke and the rocker arms can be moved by hand. If the rocker arms cannot be moved and the valves are slightly open, the No. 1 piston is on the exhaust stroke. Refer to Testing And Adjusting, "Crankshaft Positions For Unit Injector Lash And Valve Lash Setting". Find the cylinders that need to be checked or adjusted for the stroke position of the crankshaft after the timing bolt has been installed in the flywheel.Note: When the actual stroke position is identified and the other stroke position is needed, remove the timing bolt from the flywheel. Turn the flywheel by 360 degrees in the direction of normal engine rotation.Camshaft Timing

Location Of Timing Pins (Typical Example) (1) Timing hole. (2) Timing pin.
Remove rear camshaft covers from both sides of the engine.
Make reference to Finding Top Center Position For No. 1 Piston.Note: When the timing bolt is installed in the flywheel, it is not necessary to remove the No. 1 valve cover in order to find the compression stroke. Both rear camshaft covers must be removed in order to check the timing.
When the timing bolt is installed in the flywheel, look at the rear end of the camshaft. If the timing ring is visible, then the No. 1 piston is on the compression stroke. If the timing ring is not visible, feel the back of the camshaft for the groove. If the groove is at the back of the camshaft, the flywheel must be turned by 360 degrees in order to put the No. 1 piston on the compression stroke.
