4. Inspect main element and replace if necessary. If the filter
has been soaked with fuel or oil it must be replaced.
Installation
1. Reinstall the filter into the air box container. Be sure the
filter fits tightly in the air box.
NOTE: Apply a small amount of general purpose
grease to the sealing edges of the filter before
installing.
2. Check air box. If oil or water deposits are found, drain them
into a suitable container.
NOTE: Service more frequently if vehicle is operated
in wet conditions or at high throttle openings for
extended periods.
3. Install air box cover and secure with clips.
FUEL SYSTEM (EFI)
Fuel Filter
The
RANGER
4x4 500 EFI Engine uses a non-serviceable, high-
volume, high-pressure, 60-micron internal fuel pump filter and
an internal 10-micron filter located before the pump regulator.
Neither filter is serviceable.
NOTE: For all other information related to the EFI
fuel system refer to Chapter 4.
ENGINE
Compression and Leakdown Test
NOTE: 4-Stroke 500 engines are equipped with an
automatic decompressor. Compression readings
will vary in proportion to cranking speed during the
test. Average compression (measured) is about
60-90 psi during a compression test.
Smooth idle generally indicates good compression. Low engine
compression is rarely a factor in running condition problems
above idle speed. Abnormally high compression can be caused
by a decompressor malfunction, or worn or damaged exhaust
cam lobes. Inspect camshaft and automatic decompression
mechanism if compression is abnormally high.
A cylinder leakage test is the best indication of engine condition
on models with automatic decompression. Follow
manufacturer’s instructions to perform a cylinder leakage test.
(Never use high pressure leakage testers as crankshaft seals may
dislodge and leak).
