SC27G Diesel Engine Maintenance

After learning the information about Shangchai SC27G diesel engine operation and start, we are going to learn the maintenance details. Usually, there will be a maintenance plan for helping users to maintain engines. After, there are tasks and methods of engine maintenance. Following the tasks, users can easily check fuel tank, air filter service indicator, oil level and so on.

5 Engine Maintenance

5.1 Maintenance Plan

The following table gives maintenance period and tasks. Make regular maintenance based on this table. If the engine frequently operates at the ambient temperature below -180C or above 380C, or in dusty environment, the maintenance period should be shortened properly.

Note: The maintenance interval in this table is in hours, months or years, whichever comes first.

5.3 Tasks and Methods of Engine Maintenance

5.3.1 Checking engine periphery

Check the periphery of the engine each time before starting:

Check if the engine is in clean state and free from useless things on it.

Check the joints and connections of the fuel system, cooling system and lubricating system for leakage.

Check if the fan and its safety guard are fastened in place.

Check the fastening condition of the accessories.

Check the electrical circuits and the wire for intact.

Check the drive belt for intact.

5.3.2 Checking fuel tank

Check the fuel level in the fuel tank daily

5.3.3 Checking air filter service indicator

If the viewing window shows the red piston, it represents that the intake resistance of the air filter exceeds the specified value, and the filter element requires to be replaced. Refer to Section 5.3.23 for the requirement and procedure of the replacement. Press the button on the top of the service indicator for reset after the replacement.

Caution: Be sure that both end faces of the air filter are reliably sealed without leakage after the air filter element has been changed.

Caution: Do not start the engine without an air filter, and failure to do so would easily cause early engine wear.

5.3.4 Checking oil level

Check the oil level daily before starting the engine for the first time, and the oil level should be near the mark 3 (static high oil level). Or check the oil level daily at idle or low speed when the engine is in operation, and the oil level should be between the mark 2 (dynamic high oil level) and the mark l (dynamic low oil level). if oil is not enough, supplement it to near the mark 2 and if the oil level is below the mark l, add oil immediately to near the mark 2.

Caution: Do not run the engine when the oil level is below the mark l, otherwise it can result in poor engine performance, or even damage to the engine. But the oil level should not exceed the mark 2.

5.3.5 Checking coolant level

Check the coolant level daily before starting the engine or after the engine has stopped.

Warning: At operating temperature, engine coolant is hot and under pressure, and the coolant steam can cause personal injury. Do not remover the pressure cap on the radiator until the engine stops and the coolant temperature drops to below 50'C. Slowly loosen the cap to release the cooling system pressure before checking the coolant level or making supplement.

Warning: Avoid skin or eye contact with coolant to prevent personal injury because the coolant contains

alkali.

(1) Slowly loosen the pressure cap on the radiator to release pressure before starting the engine or until the coolant temperature goes below 50'C after stopping the engine.

(2) Remove the pressure cap and check coolant level from the filler or inspection port. The coolant level should remain between the marks in the radiator or expansion tank, or meet the requirement of the equipment manufacturer.

(3) Add if necessary. Coolant should be added near the upper mark or meet the requirement of the equipment manufacturer.

Caution: Coolant should be added slowly to avoid air block.

5.3.6 Checking electrolyte level

Batteries that are not maintenance-free need electrolyte

level checking.

1）Check the electrolyte level before starting the engine.

Remove the filter cap and check the electrolyte level. It should be at the bottom of the filler part. If necessary, make supplement as per requirement.

(2) Install the cap.

5.3.7 Checking first stage fuel filter and draining water

The first stage fuel filter has a function of fuel and water separation. Check daily if there is water in the water container and discharge water if any. Loosen the water drain cock to drain the water and sediment until clean fuel outflows. Then tighten the valve until you feel suitable. Don't over tighten it.
