Servicing After Every 800 Hours of Operation
*1. Remove and check fuel injectors.
Injector spray pressnre:
1988 psi
±
142 psi
(140 kg/cm 2
±
10 kg/cm 2 )
Eliminate undesirable injection conditions including
after dripping.
*2. Check the engine's compression pressure. Remove
each glow plug and check each cylinder's compression
pressure. The engine's cranking speed is at 280 rpm.

Servicing After Every 1000 Hours of Olleration
1. Remove, clean, and pressure test the primary heat exchanger. (A local automotive radiator shop
should be able to clean and test the heat exchanger.)
NOTE: Operating in silty and/or tropical waters may require that a heat exchanger cleaning be
performed more often than every 1000 hours.
*2. Check the injection pump's timing. (Static method spill time.)
A.
Rotate the engine's crankshaft to position the #1 piston at the Top Dead Center of its compression
stroke. Observe the opening and closing of the valves for this cylinder so as not to place the piston at
IDC of the exhaust stroke.
Align the IDC mark on the crankshaft front pulley with the timing marker on the front gear case
cover when positioning the # I Piston at TDC of its compression stroke. Confirm this by rotating the
crankshaft approximately 20
0
before and after this point and the two valves for the # I cylinder should
not move.
Adjust the valve clearances for both the intake and exhaust valves for this cylinder
