4.1.1 Schedule
____________________________________________
CHECK DAILY:
____________________________________________
1. If calibration fluid is low, add enough fluid to
bring the level up to the “F” on the dipstick. Use
Bacharach part number 67-5598 (SAE J967).
2. If cambox oil is lower than 3-3/4 inch from the top
of the cambox, add enough SAE 30W motor oil to
bring the level up.
____________________________________________
CHANGE OR CLEAN EVERY THREE MONTHS
(or after 120 operating hours, whichever occurs first):
____________________________________________
1. Calibration fluid
2. Filters
3. Flowmeter transducer strainer
4. Cambox oil
____________________________________________
This schedule is only a guideline; maintenance will
depend a great deal on the working environment and
the cleanliness of the injectors.
See the following sections for these procedures.
4.1.2 Changing Calibration Fluid and Filters
Calibration fluid change periods will depend greatly
on the type of service. Inspect fluid periodically for
contaminants and viscosity. Fluid must be changed
when viscosity is above 3.1 centistokes (cst) at 100°F
(38°C).
NOTE:
To check viscosity use Viscor Cup
Bacharach P/N (77-0391), part of the CD3
Audit Kit (67-7707).
