INJECTOR CALIBRATOR CD3 MAINTENANCE AND TROUBLESHOOTING
4.1.3 Changing Cambox Oil
After three months or 120 hours of operation (see
hour meter), whichever occurs first, (or if the oil
becomes contaminated) drain the oil from the cambox
and refill using the following procedure:
1. Open drain plug on bottom of cambox and allow
old oil to drain out. Drain plug is accessible after
left-hand cabinet door is open.
2. Reinstall drain plug.
3. Fill the cambox with enough SAE 30W motor oil
to bring the level up to within 3-3/4 inch from the
top (or 1-1/2 inch from the bottom).
Do not fill above the 3-3/4 inch level.
4.1.4 Cleaning and Lubricating
The CD3 calibrator will remain in good working
condition with just ordinary cleaning procedures. It is
important, however, to avoid spilling or dropping
contaminants into the drain tray where they can mix
with the calibration fluid. For the same reason,
injectors should be cleaned before being tested.
The calibrator's mechanical parts are largely self-
lubricating and therefore no special lubricating
procedures are required. The two electric motors are
sealed and lubricated for life.
4.1.5 Checking Flowmeter Cavity
The flowmeter fluid level should be checked and
refilled according to the directions in Section 2.6 after
the first 60 and 120 hours of operation. It should be
rechecked every 120 hours of operation, or sooner if
deemed necessary.
