Instruction Manual.....

(1)  Your engine needs clean Diesel of standard make. (2)  Your engine needs lubricating oil of correct grade. Maintain the correct oil in sump. (3)  Your engine needs abundant clear air.  Engine Room should be well ventilated.  Keep air cleaner clear. (4) Your engine needs genuine spare parts for its maintained.  (5)  Your engine needs regular cleaning, oiling and attention. (6)  Your engine needs tightening of all nuts after an initial run of 20 hours.  Avoid overloading the engine.

A standard engine is fitted with an exhaust silencer. If exhaust system is longer following pipe size is recommended.
Pipe line:
Up to 3 meter - 38.0mm (1.5") bore
3 to 6 meter - 50.8 mm (2") bore
6 to 10 meter - 63.5mm (2.5") bore
Over 10 meter - 76.0 mm (3") bore

Starting & Stopping

TO START ENGINEE: (1) Always form a participate to check the lubricating oil level, the fuel level and water circulating system. (2) In case of the first starting of the Engine, ensure that all the above said points of Lubrication have been attended to and that fuel system is primed to remove air locks. (3) Swing valve lifter under exhaust tappet. (4) Check and tighten, if necessary the foundation bolts. (5) Disengage Governor Hand lever by Pushing downward to enable fuel to be injected. (6) Put starting handle on the engine Crank shaft extension and rotate it. Disengage exhaust valve lifter as quickly as possible and lock in off position, Engine should free as soon as Exhaust valve is released, keep firm grip on starting handle and remove it slowly and carefully from crankshaft.(7) Check the cooling water. (8) Apply the load as soon engine attains full speed.

Failure to start or run Properly

1. Engine must turn easily when decompressed, if not, Check that valve lifter is correctly adjusted.
2. Injection creak must be heard. If not, the cause may be one or more as under:
No, fuel oil in tank
Air lock in fuel system
Fuel Pump delivery valve seat damaged.
Fuel Filter is checked.
3. Compression should be good on high compression ratio. If not check for the following (i) Wear on the cylinder (ii) Piston rings worn out or car boned In groves. (iii) Leakages rough inlet or Exhaust valve. (iv) Fuel pump rack has free movement.


CLEANING OF AIR CLEANER : Mount the air filter in a horizontal position and maintain the correct oil level as marked on the filter body, if the level is too high, the Engine will inhale the lubricating oil, which will cause excessive carbon deposits on the valves, piston etc.

VACCUM BREATHER: The function of the vacuum breather on the crankcase door is to maintain partial vacuum in the crankcase so that the lubricating oil with not pass through the bearings and joint.

TO CHECK CYLINDER HEAD CLEARANCE: Place two small pieces of lead on top of piston above the line of Gudgeon Pin and not beneath the valve of Transfer port. Tighten

Method of Removing Piston Ring

Keep the piston on a flat surface and insert thin strips of metal between the top ring and the Piston at four differences. This wills make easy to take off ring over the strips the metal. Repeat the same process for the other Rings.

Piston rings are 'SPRINGY' but will break if roughly handled.

After removing the rings, clean the Piston and Piston Ring groves perfectly.

Connecting Rod Big End Bearing

These are steel back white metal lined bearings.

Care and Patience in fitting the Big End Bearing correctly is the main factor in obtaining satisfactory bearing life. The care should be taken to see that the backs are through out clean and there is not interference between the baring and the bore of the connecting Rod.

The Tappet clearance of valves should be as under when cold:
For 6-1 inlet 0.017" (0.43mm); exhaust 0.032" (0.81mm)
For 8- 1 inlet 0.015" (0.38); Exhaust 0.015" (0.38) mm
For 9.5- inlet 0.008" (0.20mm); exhaust 0.008" (0.20mm)


It is generally agreed that Decarburizing is beneficial in most cases. To get maximum efficient working thought its life, ENGINE SHOULD NOT BE RUN MORE THAN 1000 HOURS WITHOUT DECAR BONISING
(1)Remove cylinder Head and dismantle (b) Remove Piston and Rings.ALL PARTS must be scraped clean of deposited carbon and washed with kerosene before reassembly. SPECIAL care must be taken with regard to:

(a) Recess in bore of Exhaust valve Guide (b) Valve Ports (c) Piston ring groves and interior of Piston.
The Valve and seating should be carefully examined, after cleaning no trace of pitting should be tolerated, Regrinding of the valve swats must be done if they are found to be imperfect.

Fuel Injection Equipment

TO PRIME FUEL SYSTEM: Prime the fuel system by removing all air: After filling the fuel tank, prime filter by unscrewing vent screw given on top of Fuel filter till air is released and fuel freely through the vent, Tighten up the vent screw as the system gets primed. (b) Start Engine turn by handle giving 5 to 15 turns by hand until Injection "Cracks" and then try to start the Engine.

IMPORTANT Apart from the attention given to the fuel pump delivery valve and the changing of defective Injector nozzle and valve. All other Works on fuel injection equipments must be carried out by well equipped service depots.

Fuel Pump

TO TIME INJECTION : (a) Put the Piston to Top Dead Center Compression stroke keeping both Valves closed Swing Governor downwards. (b) Disconnect Fuel Injector from delivery holder and remove delivery valve holder, delivery valve and spring. The fuel will now flow from the pump. (c) Rotate the flywheel above quarter of a turn forward until flow or fuel stops. Replace the delivery valve holder only and tighten up lightly. (d) Rotate the flywheel in reserve until fuel recommences to flow and now turn the same in the normal rotation until fuel stops to flow. Bow fuel from top of delivery holder to see that it is has stopped.

Fuel Injector

In case of trouble with fuel Injection, clean the nozzle. As the clean fuel ensures the trouble free functioning of the Engine. Injector is set at pressure shown against each engine in the Technical Data. A faulty Injection may result in one or more of the following.

(a) Smoky exhaust (Black) (b) Loss of Power (c) Overheating of Engine (d) Knocking in the Cylinder. (e) Fuel consumption more.
