The collected oil sample can be tested for the following : –

1) TOTAL DISSOLVED SOLIDS: THERE SHOULD BE NO SLUDGE OR PARTICULATE MATTER IN THE OIL.

This can be tested by passing collected oil through a filter paper & Funnel. Ref. Fig 3. Metal debris can cause accelerated wear of moving elements.

2) VISCOSITY: This can be checked by a viscometer or Ford B4 cup. Ref fig 5. This is as per IS:3944. The time taken for the B4 cup to get empty is the Viscosity. Viscosity of oil sample should be +10% of original valve. E.g. SAE 90 should be 82-98. Oil Viscosity generally changes with passage of time.

3) MOISTURE: Moisture in oil will cause lots of problems to bearings & other components. MOISTURE IN OIL SHOULD BE ZERO. Moisture in oil can easily be checked by performing a cracking test Ref. Fig. 4. Collected oil sample is put in a crucible and heated upto 100�C. You will observe a cracking sound if there is moisture, otherwise there will be no sound even at 100�C. It can also be tested by adding TOULENE to oil sample. Toulene will make the oil having moisture, translucent. i.e. milky white. otherwise their will be no change in cololur You can perform these basic tests in your own workshop or in a LAB within your works.

You may need to buy a Ford B4 Cup, other facilities are generally available in a Lab. Based on these three criterions, you can decide to change the oil, or centrifuge it, to reuse the oil. With this device in position you can MONITOR OIL QUALTIY ON LINE on a REAL TIME BASIS. NO GUESS- WORK.

Ordering code: you need to specify the following.

1) Thread size of Drain � Ref Table – 1
2) Adaptor 45�/90�, direct
3) Length ‘L’ of Adaptor for fixing bottle Ref Fig.1a.
