Fuel System

Fuel Filter

This filter provides clean, moisture free fuel for the injection process. A hand primer is provided to manually remove excess air from the fuel filter and fuel lines.

Major Components:

• Hand Primer

• Air Bleeding Screw

• Fuel Filter

Fuel enters the filter at inlet (A) and flows through the filter element separating water its contents before flowing through outlets (B) to the fuel injection pump.

Since water and contaminants settle at the bottom of the sediment bowl, a drain plug (i.e. Adaptor cum Water Sensor) is provided.

Drain water from the fuel filter when water level indicator in instrument cluster glows on.

To drain water from fuel filter, unscrew the water sensor in anticlockwise direction by hand. Rotate only 1 to 2 turns by hand. Place a small tray to collect water or water and diesel emulsion. Tighten water sensor by rotating clockwise. Tightening torque 17.7 to 26.6 lbf in. (2 to 3 Nm) or hand tighten and fix connector (C).

Servicing the Fuel Filter

1. It is recommended to replace the fuel filter every 250 hrs.

2. To remove Filter, unscrew the filter (D) from adaptor (E).

3. Check O'rings of fuel filter for any crack/damage. Smear oil on the new O'ring before installation.

4. Assemble the new filter. Do not over tighten.

5. Clean Water Sensor to remove sludge & retighten to filter.

6. Prime the system and bleed the filter. Tighten the bleeding screw.

NOTE : Drain water once in a week or whenever the water level indicator on dashboard glows "ON" continuously, if water contamination is excessive. Continued driving with water accumulation in fuel filter will cause damage to the fuel pump / other fuel system components.

NOTE : Replace fuel filter at the recommended period or whenever it gets clogged. Discard the old filter and do not repair or clean the filter. Always fit the spin-on filter dry.

Oil Level Check

Check engine oil before starting the engine.

1. Remove dipstick gauge (A) provided on the right hand side of the crankcase.

2. Oil level should be between the two marks provided on the dipstick.

Oil Change

Change Engine Oil as per Routine Service Schedule given in this Manual.

1. Ensure that the engine is stopped before changing oil.

2. Remove the drain plug provided at bottom of oil sump.

3. Allow the oil to drain completely.

4. Now reinstall the drain plug (B). Service the oil filter as explained below.

5. Remove the oil filler cap (C) in the front cover to expose the oil filler neck.

6. Refill the oil sump slowly by recommended grade of oil.

7. Clean and place the oil filler cap again.

Engine Oil Filter

The life of engine and turbocharger depends upon clean oil being circulated to its bearings. In the normal course of engine operation the lubricating oil undergoes changes which produce harmful by-products. The purpose of the oil filter is to separate and remove dirt and other injurious foreign materials from the oil and prevent these from being circulated in the engine.

The Engine oil filter should be replaced as per Routine Service Schedule given in this Manual or whenever engine oil is changed.

Changing Spin On Filter

1. Ensure that engine is stopped before changing filter.

2. Remove the lub oil filter Guard.

3. Unscrew the oil filter.

4. Prime the new spin-on filter with clean oil.

5. Screw the new filter to the adapter.

6. Move the Hand and foot throttle to engine "Idle" position.

7. Start the engine, check the oil pressure to see whether the lubricating oil is circulating through the engine.

8. Inspect the oil filter for oil leaks.

NOTE : Stop the engine immediately if Oil pressure is not recorded within 10 seconds of engine starting or Leakage is observed. Get the cause identified and rectified before proceeding further.

Turbocharger

Check the turbocharger periodically as follows.

1. Move the Hand and foot throttle to low engine "Idle" position.

2. Inspect the oil filter for oil leaks through oil supply and drain line.

3. Stop the engine immediately if leakage or abnormal sound is observed. Get the cause identified and rectified before proceeding further.
