General; Description; Engine Removal And Installation - Yale GDP16-20AF Maintenance Manual

600 YRM 496
This section has the instructions for removal, disassem-
bly, repair, assembly, installation, checks, adjustments,
and troubleshooting for the FE and F2 engines. The en-
gine specifications are given at the end of the section.
WARNING
Some gaskets used in this engine can contain dan-
gerous fibers. Breathing dust from these fibers is a
cancer or lung disease hazard. Do not create dust!
Use vacuum equipment for asbestos or follow the
cleaning procedure described below.
• Make sure the gasket material is wet with water or
oil to prevent particles in the air.
• Use a hand scraper to remove old gasket material.
Do not use a power tool or compressed air.
• Discard all asbestos material in a closed con-
tainer while it is still wet.
• Put a DANGEROUS FIBERS warning label on
the container. Discard dangerous fiber material
safely.
CAUTION
Disconnect the battery cables before doing any dis-
assembly and repair to the engine or parts of the
electrical system.
The diodes and resistors in the electrical system
can be damaged if the following cautions are not
followed:
• Do not disconnect the battery when the engine
is running. The voltage surge can damage the
diodes and resistors.
• Do not disconnect an electric wire before the en-
gine is stopped and the key switch is OFF.
The removal and installation procedures for the engine
are not included in this section.

Additional information on engine components can be
found in the sections for Gasoline Fuel System, LPG
Fuel System, and Electrical System.
• Do not cause a short circuit by connection of the
electric wires to the wrong terminals. Make sure
a correct identification of the wire is made wire
before it is connected.
• Make sure a battery is the correct voltage and po-
larity before it is connected.
• Do not check for current flow by making a spark
because the transistors can be damaged.
The Mazda FE and F2 engines have four cylinders. The
displacement of the FE is 1998 cm
displacement of the F2 is 2184 cm
firing order is 1 – 3 – 4 – 2. They are both available
with either a gasoline or LPG fuel system. The No. 1
cylinder is toward the end of the engine with the cooling
fan.
The overhead camshaft is driven by a cog belt. The
camshaft operates the rocker arms that actuate the
valves.
The crankshaft has five main bearings. The main bear-
ing in the center of the crankshaft is also the thrust bear-
ing.
The pistons are aluminum alloy and have three piston
rings. Each of the two compression rings have a special
shape designed for its position on the piston. The third
piston ring is the oil control ring.
