7. Install the SSTs into the glow plug hole.
8. Crank the engine and note the maximum gauge
reading.
9. Inspect each cylinder as above.
•If the compression in one or more cylinders is
low, pour a small amount of clean engine oil
into the cylinder and reinspect the
compression.
—If the compression increases, the piston,
the piston rings, or cylinder wall may be
worn and overhaul is required.
—If the compression stays low, a valve may
be stuck or improperly seated and
overhaul is required.
—If the compression in adjacent cylinders stays low, the cylinder head gasket may be damaged or the
cylinder head may be distorted and overhaul is required.

Warning
•Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep
sparks and flames away from fuel.
•Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injures or death and
damage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line
Safety Procedure”. (See F2–45 Fuel Line Safety Procedures.)
1. Disconnect the negative battery cable.
2. Remove the front tire (RH).
3. Remove the splash shield (RH).
4. Remove the washer tank.

OIL COOLER FLUSHINGA6E571419900202
Caution
•Power flushing should be performed very carefully when removing the accumulated debris from
the fluid baffle, otherwise the debris cannot be removed or the problem becomes even worse.
Note
•The contaminated cooler line (oil pipes and hoses) and auxiliary cooler (if equipped) must be flushed
completely when ATX is overhauled or replaced.
•Performing back and reverse power flushing two times each does not work because debris or particles
flow out from the feed pipe side of ATX.
Recommended power-flushing manufacturer
Power Flushing
Repair procedure
1. Before power flushing, inspect the hoses/lines and clamps. Power flushing must begin with back flushing
followed by forward flushing to quickly dislodge the restriction. If back flushing is not performed before forward
flushing, the restriction could further reduce the ATF flow through the internal mesh type baffle of the cooler and
flushing will not be effective or possible.
Inspecting oil lines & clamps
1. Be sure to inspect the lines (hoses/pipes) for cuts, crimps (pinched), cracks or any other damage before
reusing them. If any problem exists replace it.
Caution
•Always use new clamps when replacing hoses.
