TECHNICAL BULLETINS

The amount of oil, in ounces, normally in the bearing housing. ________oz.

1. Multiply above answer by 1.804 to obtain _______in³ (oil volume). Place this value into the table below STEPS A & B in³ (oil volume).
2. The temperature range of the bearing housing. High _______of Low _______of. Place High & Low temperature in STEP C. Subtract the low from the high and place in STEP A (high-low temp).
3. Complete STEP A. Multiply oil volume by temperature difference and coefficient of expansion. (NOTE: .0004 is coefficient of expansion for most turbine oils). Place answer in STEP D, in³ (oil expansion).
4. The total volume of the bearing housing. Many customers may not know this. Contact your pump manufacturer for this information. ________oz. (total volume).
5. Multiply answer from above by 1.804 to obtain _______in³ (sump volume). Place this value into the table STEP B in³ (sump volume).
6. Complete STEP B, subtract in³ (oil volume) from in³ (sump volume) to get in³ (air volume) and place answer in both places in STEP C, in³ (air volume).
7. Follow instructions in STEP C to get in³ (air expansion). Place answer into STEP D in³ (air expansion).
8. Complete STEP D by adding to get in³ (total expansion), with this information you can select the correct size expansion chamber for you application.
