OIL SAMPLING PROCEDURE
1/1
1. OBJECT
This Product Information sheet clearly specifies a procedure for collecting oil samples from all
Kohler
engines,
for their subsequent analyses.
2. SAMPLING ROCEDURE
-
The oil sample for analysis must be representative of the entire operating load. Therefore, always do the
sampling when oil is circulating in the engine, since this ensures product homogenization.
-
When collecting oil, take great care to avoid external contamination. In particular, check that the sample
containers are perfectly clean and dry.
-
You may sample oil during an oil change, but bear in mind that you should not take samples at the beginning
or end of the oil sump draining process.
-
To take samples for analysing the oil condition when there is a sampling valve (unit ref. 31.25.920) available,
remove the cap from the sampling valve.
-
Where there is no such sampling valve available, we recommend sampling on a pressure oil line or, failing
this, direct from the oil sump.
-
NEVER take samples from the first jet of oil coming out when you open the sampling valve; always drain
about 400ml of oil to eliminate any contaminating residues present in the circuit. When done, reset the valve
cap.
-
Finally, stick a label on the sample, stating all the relevant data: date, engine, type of oil, operating time of
engine, operating time of oil, engine oil consumption.
