Checking Fuel Injection Timing
NOTE:
Some fuel may drain from the fuel injection pump
during this process. Make provisions to contain any
such spillage.
1. Turn off the fuel valve in the fuel supply hose and the fuel
return hose.
2. Clamp shut the fuel injection pump fuel return hose
leading to fuel filter (1, Figure 278).
Clean the top of the fuel injection pump to prevent any
contamination when the fuel injection pump plunger plug
is removed.
3. Remove the forward fuel injection pump plunger plug (2,
Figure 278) on the top of the fuel injection pump.
4. Install a dial indicator adapter and clamp into the pump
plunger opening.
NOTE:
Use the M16 adapter used on the MP4 fuel
injection pumps and plunger adapter clamp (1,
Figure 279).
5. Install a dial indicator (1, Figure 280), Mitutoyo or
equivalent, with a 30 mm extension, into the adapter.
Secure with the plunger adapter clamp (1, Figure 279) at
approximately the mid-point of its travel.
NOTE:
Note: The following references to the direction-
of-rotation are facing the coolant pump end of
the engine and are adjusted by turning the
crankshaft pulley.
