Generac 005030-0, 005028-0, 005031-0 Exhaust Manifold Procedure, Intake Manifold Procedure

Section 4 — Maintenance

Liquid-cooled 15, 20 and 25 kW Generators

7.Turn the voltage regulator’s VOLTAGE ADJUST pot to obtain a line-to-line voltage of:

A.240 VAC if the generator has been configured for

60 Hertz operation.

B.200 VAC if the generator has been configured for

50 Hertz operation.

8.If the RED REGULATOR LED is flashing, adjust the STABILITY pot in either direction until the flashing stops.

9.Apply an electrical load and check the engine speed recovery.

A.Adjust the UNDERFEQUENCY ADJUST pot CCW to reduce load during engine recovery.

B.For flat regulation (no voltage decrease as fre- quency drops) set the UNDERFREQUENCY ADJUST pot fully CW.

C.To obtain a constant voltage regulation as fre- quency decreases, set the UNDERFREQUENCY ADJUST pot fully CCW.

10.With the electrical load still applied, check the REGULATOR LED for flashing. If the LED is flashing, adjust the STABILITY pot until the flash- ing stops.

11.If better response is needed, adjust the GAIN pot clockwise (CW) as needed. Then (if needed) cor- rect for stability by adjusting the STABILITY pot.

12.Turn OFF the electrical loads.

13.Verify that all the voltage regulator’s LED’s are ON.

14.Turn OFF the generator.

D. FIRST 100 OPERATING HOURS

1.Change engine oil and oil filter. After initial change, service engine oil and filter at 150 oper- ating hours or six months, whichever comes first.

2.Retorque cylinder head (see torque specs).

3.Retorque intake and exhaust manifold (see torque specs).

E. EVERY 500 OPERATING HOURS

1.Service air cleaner.

2.Check starter.

3.Check engine DC alternator.

F. EVERY 800 OPERATING HOURS

1.Retorque cylinder head (see torque specs).

2.Retorque intake and exhaust manifold (see torque specs).

3.Check engine compression.

4.Check valve clearance.

4.2EXHAUST MANIFOLD PROCEDURE

1.If necessary, clean gasket surfaces on exhaust manifold and cylinder head.

2.Install exhaust manifold and exhaust manifold gasket.

3.Install fasteners.

NOTE:

Exhaust manifold fasteners must be tightened in two stages.

4.1MAINTENANCE PERFORMED BY AUTHORIZED SERVICE FACILITIES

A. EVERY THREE MONTHS

1.Check battery condition.

2.Inspect and test fuel system.

3.Check transfer switch.

4.Inspect exhaust system.

5.Check engine ignition system.

6.Check fan belts.

4.Tighten fasteners to 20-30 N-m (15-22 lb-ft) dur- ing the first stage.

5.Retighten fasteners to 60-80 N-m (44-59 lb-ft) during the second stage.

4.3INTAKE MANIFOLD PROCEDURE

1.Clean and inspect the mounting surfaces of the intake manifold and the cylinder head. Both sur- faces must be clean and flat (Figure 4.1).

2.Clean and lightly oil the manifold bolt/stud threads.

B. ONCE EVERY SIX MONTHS

Figure 4.1 — Intake Manifold Installation

1.Test Engine Safety Devices (low oil pressure, low coolant level, high coolant temperature).

C. ONCE ANNUALLY

1.Test engine governor; adjust or repair, if needed.

2.Clean, inspect generator.

3.Flush cooling system.
