I felt short of words to pin down anything for those who kept the ship afloat for the past month with their guidance, co-operation and expert advice. The successful completion of any training depends upon the co-operation, co-ordination and combined efforts of several resources of knowledge, inspiration, and energy.

I am very grateful to MR. V.P. SINGH, G.M. of the training department, for allowing me to be a part of such an esteem organization of him. I am grateful for the patience, and interest everybody in the organization has shown completion of any training depends upon the co-operation, co-ordination and combined efforts of for me.

With this I convey my sincere thanks to Prof. R.P. Sharma, the Director and faculty of the Automobile Department for sharing his valuable knowledge with us. And last but not the least I take this opportunity to thank Mr. Arun Arya, the Head of Department of Automobile Engineering Department at Arya College of Engineering & I.T., Jaipur for providing me the opportunity to do my four-week industrial training at such an esteemed organization. Also the whole faculty at the department has been resourceful for the industrial training for which I appreciate their efforts.


Before joining my training, I had no idea what it is going to be and what exactly is its need in the academic curriculum. By the time I finished my training I had understood how important it was for me to be a complete engineer.

A fresh graduate would have absolutely no idea of the functioning of an industry. He would probably be unaware of the various departments and their functioning. He would be completely ignorant of the working and environment. He generally would not know about the department in an enterprise. Thus industrial training prepares you to walk out of your college and join the industry. You need to have basic professional knowledge along with the theoretical background and spending a month among hardcore professional can teach you a lot.

The following report does not discuss the details of these experiences and discuss mostly the training and how it was completed. It is a much more fulfilling experience than any report will be able to express. I feel the pride to get an opportunity to have my practical training at INTERNATIONAL TRACTORS LIMITED HOSHIARPUR.

I thank everyone who has contributed to making this experience truly complete and stimulating.

Quality Assurance activity in ITL is an MIS function to audit and report the quality status of both, product as well as quality assurance within the plant. ITL considers vendors as an extension of its own manufacturing operations. Hence, the quality assurance audits are not limited to just received components quality at ITL receipt inspection stage but extend to the audit of conformance to prescribed quality assurance systems at vendor end also.


  • ¬†To reduce rejection and achieve better quality standards.
  • ¬†To achieve consistency in quality.

Quality, which has no compromise, is essential for every industry to stay affirm in today’s competitive world. My project is long-term planning of every industry. Each industry feels to upgrade its position and vendors are integrated part of it. Quality improvement at Vendor’s end means overall improvement in the company’s graduation. With the high quality of components from vendors, a major goal of improvement can be achieved.


The Assembly at SONALIKA DIVISION deals with the assembly of tractors model DI 730 II, DI 35 II, DI 730 II, DI 745 III, DI 60 (Mileage Master), DI 60 RX, DI 750, etc.
Assembly is the joining of various constituents to form a final product. The assembly process is carried out on the main line, which has various subassemblies along its length.

Assembly shop can be divided into two main areas:-

  • ¬†Before the paint area
  • ¬†After the paint area


The areas before painting can further be divided into subassemblies/loops namely:

  1.  Differential loop
  2.  Gearbox loop
  3.  Rear cover loop


  1.  Differential casting is mounting on the trolley after washing.
  2.  Bull pinion shaft left and right fitted.
  3.  Cage assembly fitted. It consists of:
  4.  Crown wheel
  5.  Tail pinion assembly
  6.  Roller bearing
  7.  Bevel wheels.
  8.  PTO shaft fitted.
  9.  Rear axle trumpet is fitted.
  10.  PTO shifter assembly fitted.
  11.  Gearbox assembly is fitted.
  12.  Rear cover assembly fitted.
  13.  Brakes are fitted.
  14.  Parking brake.
  15.  Suction pipe.
  16.  PTO covers.
  17.  A trailer hook is fitted.
  18.  The angle bracket is fitted.
  19.  Rocket link is fitted.
  20.  Footboard is fitted.
  21.  The clutch pedal is fitted.



If an axle is a single unit and the wheels are free on the axle that is just moving on the bearings, as is the case of tractor front axle, the wheels will turn at different speeds to compensate for the difference in travel. However when the wheel is driven positively by the engine, a device is necessary which can make the wheels move at different speeds on turns, whereas the speed of both the wheels should remain equal when the tractor is following a straight path. To accomplish this purpose a system of gears called ‚Äúdifferential system‚ÄĚ is provided. Thus the differential has two functions:

  1.  On straight travel it allows both the rear wheels of the tractor to get equal power.
  2.  On turns, it allows the inner wheel to move slower than the outer wheels.

As far as transmitting of power at a right angle to propeller shaft is concerned drive pinion is coupled to transmission shaft with the help of flange. This pinion drives the crown wheel as such the power is now available at a right angle to drive shaft and tractor can move forward and backward as per requirement.


The engine drives the crown wheel mounted on the cage assembly through tail pinion. Four bevel pinions are mounted on the splined bull pinion shafts lt. and rt. which are supported on the taper roller bearings in the differential housing. These taper roller bearings give rigid support to cage assembly. The differential system is very useful in the automobiles. This help in turning the vehicle.

As already discussed the above cases that how the vehicle differential works while the vehicle is taking a turn. During the turning the inner speed of the wheel reduces, and the outer wheel moves faster than the inner wheels. The differential on the vehicle distributes the power between the two wheels by giving the less power to the inner wheel than the outer one & the vehicle moves easily. The steering system is used for the turning of the vehicle on the cross, which is fitted in the cage assembly.
