TEST PROCEDURE FOR OIL PULL OVER OF OIL BATH TYPE AIR CLEANER

Preparation:

1. Weigh the Sample of Air Cleaner with out Oil.
2. Fill oil up to the Marked level in the Air Cleaner Bowl.
3. Weigh the Air Cleaner With Oil.
4. Pour 10% more oil in the Air Cleaner Bowl.
5. Weigh the Air Cleaner with Additional Oil.
6. Record the mass of total oil in the Air Cleaner.

Step 1 (On Level Ground):

1.  Park the Tractor on the Level Ground and mount the Air Cleaner on it.
2. Attach Mercury Manometer on suction hose to measure Suction Pressure (as shown in figure).
   
   
3. Start the Tractor and keep it on full Throttle for 15 minutes.
4. After this put the tractor on Sudden acceleration and deceleration (Full throttle for 30 seconds and Low idle for 30 seconds) up to 15 minutes.
5. Record Observations.

Step 2 (On 15º Slope):

1.  Now park the tractor on the 15 deg slope (Front of Tractor on upper side).
2. Start the Tractor and keep it on full Throttle for 15 minutes.
3. After this put the tractor on sudden acceleration and deceleration (Full throttle for 30 seconds and Low idle for 30 seconds) up to 15 minutes.
4. Record Observations.

Observations for Both steps:

1. Air Cleaner Suction Pressure (Difference in Hg column height of Manometer).
2. Take out Air Cleaner from the Tractor and weigh it.
3. Record the mass of Oil in the Air Cleaner.
4. Calculate the Percentage Loss of Oil.

Conclusion:

1.  Percentage loss of Oil should be less than 0.20% of Total Oil in both the cases.
2. Suction Pressure of Air Cleaner should be less than 18 mm of Mercury Column.
