(3) Adjustment of Injection Timing
The injection timing may not be readjusted.
Take care not to forget to insert a shim on the mounting surface
when reassembling the injection pump after it was removed.
(4) Cylinder Compression Pressure Measurement
The cylinder compression pressure measurement must be done
every 1000 operation hours, or whenever the engine output is
reduced.
Compression pressure 3.04 MPa (441 psi)
Test condition:
Cranking speed 250 min-l
Coolant temperature 75°C (167°F)
Repair the engine and/or replace some parts of engine if
compression pressure is lower than 2.55 MPa (370 psi)
(5) Starter and Generator Servicing
Do the starter and the generator servicing every 1000 operating
hours on the following items.
l
Starter commutator cleaning.
l
Alternator slip ring cleaning.
l
Carbon brushes and the brush contact check.
(6) Radiator Pressurization Valve Check
A pressurization valve is incorporated in the radiator cap
assembly. Check the valve actuating pressure with a radiator
compression tester. For the pressurization valve actuating
pressure and the check interval, follow the equipment
manufacturer’s standards.
