Priming The Fuel System; Engine Service And Components; Cooling System; Lube Oil Filters - Carrier 69GL15-114 Operation And Service

4.2 PRIMING THE FUEL SYSTEM

The unit is equipped with a mechanical fuel lift pump,
it is mounted on the engine next to the injection pump.
Since the unit employs a closed fuel circuit, it is
recommended to use the following steps:
1. Turn bleed valve
counter-clockwise until fully opened (see Figure 1-1 or
Figure 1-5).
2. Start engine. (Refer to section 2.3.)
3. When engine is running properly, turn bleed valve
clockwise until fully closed.

4.3 ENGINE SERVICE AND COMPONENTS

4.3.1 Cooling System

The blower fan and grille, must be clean for adequate
cooling. The blower fan belt is adjusted automatically to
provide maximum air flow. (Refer to section 4.4.)

4.3.2 Lube Oil Filters

The engine oil filter is located next to the fuel solenoid
as shown in Figure 1-1.
After warming up the engine, stop engine, remove
drain plug from oil reservoir and drain engine lube oil.
Lightly oil gasket on filter before installing.
Replace filters and add lube oil. (Refer to section
1.4.j.) Warm up engine and check for leaks.

4.3.3 Servicing the Fuel Solenoid and Linkage

NOTE
Periodically grease (P/N 07-00245-00) Fuel
Solenoid plunger.
a. Remove run stop lever assembly (item 4,
Figure 4-1).
b. Remove support rod (not shown) from mounting
bracket, item 2.
b. Disconnect wiring to solenoid. Remove mounting
hardware from solenoid and then remove solenoid.
c. Install new solenoid and mounting hardware,
connect wiring. Make sure that the half-moon notch in
the run stop lever assembly is facing up. Place ignition
(Start-Run-Off) switch in the START position to
energize solenoid. Check to ensure that the solenoid
plunger bottoms out at the end of its stroke at the same
time the fuel lever assembly hits against its stop.
d. De-energize solenoid. If the engine does not shut
off when the fuel solenoid is de-energized, loosen jam nut
and turn for adjustment. Retighten jam nut.

4.3.4 Adjusting Engine Speed

The engine speed operates at 1825 rpm (no load),
1800 rpm (with load).
Two methods to check engine speeds are:
a. With the engine stopped, place a mark (white
paint for example) on the crankshaft sheave. Start engine
and verify engine speed by using a Strobette-model 964
(Strobetachometer), Carrier Transicold Part Number
07-00206.
b. With the engine stopped, the second method of
checking engine speed is by using a frequency (hertz)
meter. Attach one lead to CB-1, terminal 1, electrical
schematics, and the other to chassis ground. Start engine
and 60.5 hertz will be 1800 rpm and 61.3 hertz will be 1825
rpm (no load).
