TECH TIPS
We could tell you why your starter failed, but
we thought you might like to see for yourself.
If left unchecked, these problems will result in premature
starter failure REGARDLESS of the STARTER MANUFACTURER.
Although the outside of the starter
(at bottom right) looks ffne, the
flywheel picked up water from the
bilge and pumped it inside the
starter causing the corrosion
shown here.
WATER INTRUSION IS THE #1 CAUSE OF STARTER FAILURE. If
water gets pumped into the motor portion of the starter from the
flywheel, it will not drain out. As you can see, rust and corrosion
will destroy the inside components of the starter.
Shown here are damaged starter mounting pads.
Water ingested into the engine stresses the
mounting bolts beyond normal conditions. The
bolts stretch and cause the starter to become loose.
This could eventually lead to damage to the ring
gear, starter casting and possibly the
entire engine block.
THE #2 CAUSE OF STARTER FAILURE IS WATER INGESTED INTO
THE ENGINE. Leaking exhaust manifolds, gaskets and risers are often
the source. Damage to the mounting pads, as shown above, indicate
the starter has been loose on the engine; possibly caused by water
ingestion into the cylinder. Although the engine may not experience
a complete hydro lock, if enough water is on top of the piston
to raise the compression to a high level, the starter
bolts and mounting pads will be stressed
beyond normal load conditions.
DON’T BE FOOLED BY OUTWARD
APPEARANCES. As shown here, the
outside condition of the starter appears to be ffne, but by removing and inspecting the
lower starter case bolt, it is obvious water has gotten inside the starter.
These problems are not the fault of the starter.
Simply replacing the starter without ffrst locating and
correcting the source of water intrusion will only
result in more starter failures.
