Scheduled Oil Sampling (S O S)
To compliment a good preventive maintenance program, Caterpillar recommends using S O S at regular scheduled intervals to monitor the condition and maintenance requirements of your engine.Obtain Sample
Each oil sample should be taken when the oil is warm and well mixed to ensure that the sample is representative of the oil in the crankcase. There are two methods recommended to obtain S O S samples from the 3116 engine crankcase.1. Use the sampling valve, if installed on the engine, for samples.2. Use a sampling gun inserted into the sump.Caterpillar recommends using one of the above methods. If these methods are not possible, then use the drain stream method when changing oil. When using the drain stream to obtain the oil sample, DO NOT sample from the first or final drain stream. The oil at the beginning or end of the drain stream is not mixed well enough to be representative of the oil in the crankcase. Consult Caterpillar for a step-by-step explanation of sampling crankcase oil, and for complete information and assistance to establish an S O S program for your engine.Engine Oil and Filter(s)
The vehicle must be parked on a level surface to perform this maintenance procedure.Make sure you read and understand the information in the Safety and Lubricant Specifications sections of this Manual before you proceed with this maintenance.
Severe Service is indicated by the following conditions.* Marginal lube operation and excessive metal in oil filter.* When Scheduled Oil Sampling (S O S) detects: Excessive lube oil sooting.Fuel contamination.Coolant contamination.Excessive lead (Pb) and aluminum (Al). Not all oils with identical API specifications have equal performance. Use of oils that do not have the API CF-4 or CE designation will require reduced oil change intervals than that listed in the Maintenance Schedule.Drain Oil
* Drain the crankcase with the oil warm and the engine stopped to allow for the draining of waste particles that are suspended in the oil.1. Operate the engine until it reaches normal operating coolant water temperature. STOP the engine. 2. Remove the crankcase drain plug and allow the oil to drain. Plugs from both the deep and shallow portions of the oil pan should be removed to allow the oil to drain. An oil sample for Scheduled Oil Sampling analysis should have been obtained from the S O S valve (if equipped) or from the crankcase drain at this time.3. Install the crankcase drain plug and tighten it to 25 5 N m (18 4 lb ft) if equipped with the cast aluminum oil pan, or 50 5 N m (36 4 lb ft) if equipped with the stamped steel oil pan.Replace Filter(s)
Change oil filter(s) at every oil change. Make sure to use the correct Caterpillar oil filter(s) for your engine arrangement.
Caterpillar oil filters are built to Caterpillar specifications. Use of an oil filter not recommended by Caterpillar could result in severe damage to your engine bearings, crankshaft, etc., as a result of the larger debris
