EXTENDED OIL FILL AND DIPSTICKS
When installing the extended oil fill and dipstick
assembly, the tube must be installed so the "O" ring seal
is firmly compressed. To do so, push the tube downward
toward
the
sump,
then
tighten
blower
housing
screw, which is used to secure the tube and bracket.
When the cap and dipstick assembly is fully depressed
or screwed down, it seals the upper end of the tube. See
Fig. 5.
Fig. 5. Extended Oil Fill and Dipstick
A LEAK AT THE SEAL BETWEEN THE TUBE AND
SUMP, OR AT THE SEAL AT THE UPPER END OF
THE DIPSTICK CAN
RESULT
IN
A
LOSS
OF
CRANKCASE VACUUM, AND A DISCHARGE OF
SMOKE THROUGH THE MUFFLER.
Caution owners not to overfill the sump or crankcase
with oil when using the extended filler and dipstick. The
dipstick is marked "DO NOT OVERFILL." Excessive oil
will cause a smoking condition, as the engine attempts to
discharge the surplus oil.
Various styles of extended Oil Fill and Dipsticks are
shown in Figs. 6, 7, 8 and 9.
