4J5: Engine Transmissions
CHECK THE TRANSMISSION OIL LEVELS
once
every two weeks, more often if a transmission shifts
erratically, with the dipstick on the starboard side of
each transmission. It is unlikely that any oil will
need to be added. Be sure to check under the
transmissions for leaks! Low transmission oil is a
serious matter.
With the engine idling, remove the
transmission dipstick. Wipe it with a
towel, reinsert it, and take a reading.
If the level is below the add mark,
stop the engine, add a pint of 30-
weight high-quality non-synthetic engine oil through the plug in the top of the
transmission case, and then start the engine and measure again. Do not overfill,
for to do so could cause the seals to “blow out”.
The transmissions are fitted with oil coolers. Be sure to service the zincs on the coolers
when the engines’ zincs are serviced.
The port transmission is fitted with a hydraulic pump for the Naiad stabilizer system.
Check the hose fittings for hydraulic fluid leaks.
