808171 Volvo.Penta Oil pressure gauge

The oil change interval will be affected by the following items:
Engine application
Fuel type
Oil type
Ambient air conditions
Air/fuel ratio
Size of the oil sump
Table 1
C175 Engine Oil Change Intervals
Sump Interval
Standard/Shallow 1000 service hours
Deep 2000 service hours The S O S oil analysis program analyzes used oil in order to determine if the oil change interval is suitable for your specific engine.Drain the Engine Oil
Do not drain the oil when the engine is cold. As the oil cools, suspended waste particles settle on the bottom of the oil pan. The waste particles are not removed when the cold oil is drained. Drain the crankcase when the oil is warm. This draining method allows the waste particles that are suspended in the oil to be drained properly.Failure to follow this recommended procedure will allow the waste particles to be recirculated through the engine lubrication system with the new oil.
After the engine has been operated at normal operating temperature, STOP the engine.
Drain the oil according to the equipment on the engine. Note: The threads that are provided on the drain valve are metric. Drain the oil into a suitable container. Dispose of the oil according to local regulations.

(1) Oil drain valve
(2) Oil drain plug
Open oil drain valve (1). Oil drain plug (2) may also be used to drain the oil. After the oil has drained, close the oil drain and/or reinstall the drain plug.
If a suction device is inserted into the oil pan, ensure that the suction device is clean. The suction device will prevent dirt from entering into the oil pan. Be careful not to strike the engine oil suction tubes or the piston cooling jets.
If a suction device that attaches to the oil drain is used, ensure that the suction device is clean. Attach the suction device to the oil drain. Open the oil drain. After the oil has drained, close the oil drain and remove the suction device. Replace the Oil Filter Elements
Replace the engine oil filters when either of the following conditions are met:
Every oil change
The engine oil filter differential pressure reaches 103 kPa (15 psi).Service tools are available to aid in the service of oil filters. Consult your Caterpillar dealer for the part names and the part numbers. Follow the instructions that are supplied with the service tools. If the service tools are not used, perform the following appropriate procedure.

(1) Bolts
(2) Cover
(3) Drain valve Note: Drain the oil into a suitable container. Dispose of the oil according to local regulations.
Connect a hose to drain valve (3). Place the other end of the hose into a suitable container in order to collect the oil.
Open drain valve (3). Allow the oil to drain. Clean the plug and install the plug. Close the drain valve. Remove the hose from the drain.
Personal injury can result from parts and/or covers under spring pressure.Spring force will be released when covers are removed.Be prepared to hold spring loaded covers as the bolts are loosened.
Note: Some oil will remain in the housing after the oil has been drained. This oil will pour out of the housing when cover (2) is removed. Prepare to catch the oil in a suitable container. Clean up any spilled oil with rags. DO NOT use absorbent particles to clean up the oil.
Be alert to the spring force. Gradually loosen but do not remove bolts (1). Before removing bolts (1), pry the cover (2) loose in order to relieve any spring pressure. Remove cover (2). Remove the O-ring seal on the inside of the cover.
Clean cover (2) and clean the O-ring seal. Clean the inside of the oil filter housing.
Caterpillar oil filters are built to Caterpillar specifications. Use of an oil filter not recommended by Caterpillar could result in severe engine damage to the engine bearings, crankshaft, etc., as a result of the larger waste particles from unfiltered oil entering the engine lubricating system. Only use oil filters recommended by Caterpillar.
Install new oil filter elements.
Inspect the O-ring seal. Ensure that the surfaces for the O-ring seal are clean. Install a new O-ring seal if the old O-ring seal is damaged or deteriorated.
Install cover (2). Ensure that the springs are seated properly between the cover and the oil filter elements. Inspect the Used Oil Filter Elements
Cut the used oil filter element open with a utility knife. Remove the metal wrap. Cut the filter element free from the end caps. Spread apart the pleats and inspect the element for metal debris. An excessive amount of debris in the element may indicate early wear or a pending failure.Use a magnet to differentiate between the ferrous metals and the nonferrous metals that are found in the element. Ferrous metals may indicate wear on the steel and the cast iron parts of the engine. Nonferrous metals may indicate wear on the aluminum parts, the brass parts, or the bronze parts of the engine. Parts that may be affected include the following components: main bearings, rod bearings, turbocharger bearings and cylinder heads.Due to normal wear and friction, small amounts of debris may be found in the oil filter element. If an excessive amount of debris is found in the oil filter element, consult your Caterpillar dealer in order to arrange for further oil analysis.Fill the Crankcase
Remove the oil filler cap. Fill the crankcase through the oil filler tube only. For the correct type and the amount of oil to use, refer to this Operation and Maintenance Manual (Maintenance Section), "Refill Capacities and Recommendations". Clean the oil filler cap. Install the oil filler cap.
To prevent crankshaft or bearing damage, crank engine with fuel off to fill all filters before starting.Do Not crank engine for more than 30 seconds.
Close the fuel supply line and crank the engine until the oil pressure gauge indicates 70 kPa (10 psi). Open the fuel supply line. Allow the starting motor to cool for 2 minutes before cranking again.
Follow the Operation and Maintenance Manual (Operation Section), "Starting The Engine" procedure. Operate the engine at low
