Section 4 — Maintenance

Liquid-cooled 15, 20 and 25 kW Generators

3.Install a new lower intake manifold gasket.

4.Position the lower intake manifold to the cylinder head.

5.Install retaining bolts/studs finger tight.

6.Tighten all bolts/studs to specifications in the tightening sequence shown:

•First pass = 7=10 N-m (5-7 lb-ft).

•Final pass = 26-38 N-m (19-28 lb-ft).

4.4CYLINDER HEAD PROCEDURE

1.Position head gasket on the block (Figure 4.2).

2.Position cylinder head to cylinder block.

3.Install 10 cylinder head bolts in numerical sequence. Tighten to 70 N-m (52 lb-ft) in sequence. Retighten to 70 N-m (52 lb-ft) in sequence. Then turn all head bolts an additional 90 - 100 degrees in sequence.

4.5COOLING SYSTEM

Air intake and outlet openings in the generator com- partment must be open and unobstructed for contin- ued proper operation. This includes such obstruc- tions as high grass, weeds, brush, leaves and snow.

Without sufficient cooling and ventilating air flow, the engine/generator quickly overheats, which causes it to shut down. (See the installation diagram.)

20

The exhaust system parts from this product get extremely hot and remains hot after shutdown. High grass, weeds, brush, leaves, etc. must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system.

4.6OVERLOAD PROTECTION FOR

ENGINE DC ELECTRICAL SYSTEM

Engine cranking, start up and running are controlled by a solid state Engine Controller circuit board. Battery voltage is delivered to that circuit board via a 15 amp fuse. These overcurrent protection devices will open if the circuit is overloaded.

If a circuit breaker opens or a fuse element

!melts, find the cause of the overload before resetting the circuit breaker or replacing the fuse.

4.7CHECKING FLUID LEVELS

‹4.7.1 CHECK ENGINE OIL

Check engine crankcase oil level (Figure 4.3) at least every 20 hours of operation, or prior to use.

•Remove oil dipstick and wipe dry with a clean, lint-free cloth.

•Install oil dipstick, then remove again.

•Oil should be between FULL and ADD marks.

•If oil level is below the dipstick ADD mark, remove oil fill cap. Add the recommended oil to bring oil level up to the FULL mark. DO NOT FILL ABOVE THE “FULL” MARK. See “Engine Oil Recommen- dations” for recommended oils.
