PREFACE
Industrial training now a day’s one & the only one method to make students familiar with the modern
techniques, latest equipments& methods used in various industries. During industrial training, students visit to
various companies and make themselves familiar with the practical aspect of the production method.
This training has provided and ultimate experience& opportunity to have practical knowledge which has
increased my level of thinking and dealing with different kinds of people in all walks of life. It helps us a lot
while appearing to the interviews. Industrial training in proves the theoretical and the practical concept of the
student about engineering.
The well planned, properly executed & evaluated industrial training helps a lot in inculcating good work
culture. It provides linkage between the students & the industries in order to develop and awareness of
industrial approach to problem solving based on broad understanding of plant.

ESCORTS GROUP
An introduction
The Escorts Group is an Indian multinational engineering conglomerate that operates in the sectors
of Agri- machinery, construction and material handling equipment, railway equipment and
auto components. Headquartered in Faridabad, Haryana, the company was launched in 1944 and
has operations in more than 40 countries.
Escorts Agri-Machinery (EAM)
Built with a mission to improve agricultural productivity and improve the quality of life in rural
India, it pioneered farm mechanization in the country and since then has played a pivotal role in
the agricultural growth of India for over five decades.
Escorts Agri Machinery has three recognized and well-accepted
tractor brands, which are on distinct and separate technology
platforms:

TIMING GEARS
Timing gears are the gears through which the crankshaft drives the camshaft and thus controls
valve timing in a four-stroke cycle internal-combustion engine, which ensures the correct timing
to best fill the cylinder with an air/fuel mixture as well as to release all of the spent fumes from
the exhaust cycle of the cylinder.
In the perfect relationship of timing, the timing gear can be set, so that the intake valve will begin
to open as the piston is still moving downward in the cylinder walls and sucking the fuel into the
cylinder. This would aid in getting as much fuel as possible into the combustion chamber.
Also, the exhaust valve would remain open as long as the piston was moving upward in the
cylinder and pushing the exhaust fumes out of the combustion chamber so that there is no
contamination to the incoming fuel mixture.
There are 3 Timing Gears that combine to form a drive, which transfers motion from the
crankshaft to the camshaft.
411:
This is the gear that is mounted on the crankshaft.

Hydraulic PowerPack
 Hydraulic power packs are stand-alone devices, as opposed to a built-in power supply
for hydraulic machinery.
 Some power packs are large, stationary units and others are more portable.
Hydraulic Pack Components:
 Hydraulic Pump: This pump is the source
of pressure build-up, due to which the fluid
is able to travel within the system.
 Motor: A motor, generally electrical, is present in the
 HPP to drive the pump
 Hydraulic Reservoir: This houses the
Hydraulic fluid, which is circulated in the
system
 Pressure Regulators: These regulators
allow the user to control the amount of
pressure the power pack delivers to a valve.
 Pipelines: The fluid travels to the required
location through these pipes.
 Direction Control Valves: They are used to
control the path of fluid flow in the hydraulic
circuit.
 Pressure Relief Valves: The relief valve is used to control or limit the pressure in a
system. If excess pressure is encountered in the system, this valve is actuated, and directs
fluid flow back to the tank, thus limiting pressure.
 Breather: In every closed hydraulic tank, an air breather is mounted on air chamber side.
 Its function is to maintain the pressure on the hydraulic oil, to allow the suction pressure
for the pump, and release excess pressure to atmosphere in order to maintain pressure in
hydraulic tank
 It also sucks air from the atmosphere, if pressure drops, thus maintaining pressure
 Oil Filter: Filter placed on the passage through which oil is poured into the reservoir,
which prevents particles such as dust, debris, metal chips etc. from entering the
reservoir
 Oil level Indicator: An indicator, that lets the operator know when the re-filling of the
oil needs to take place.
 Pressure Gauges: A gauge that displays the pressure at which the oil is being supplied
to the machine

20. 20
Operation:
 Hydraulic power uses pressurized fluids to run machinery. Hydraulic power packs
provide hydraulic power to a valve in another machine
 Hydraulic power packs typically offer a choice of valve connections, allowing users to
connect them to a control valve or valves to power a variety of machines. The power
pack supplies hydraulic power through a control valve to run another machine.
 During normal operation, the hydraulic pack is designed to operate on demand in parallel
with the system pump associated with the control valve(s). When product is required
through the control valves, other presets signal the HPP to turn on and actuate the control
valves. When the complete volume has been delivered, the control valve is closed and
HPP is turned off. This reduces the run time of the system, which reduces wear and power
consumption.
Maintenance:
 Hydraulic power packs need regular maintenance to extend their life and to allow safe
operation.
 Maintenance includes checking the tubing for dents, cracks or other problems, changing
the hydraulic fluid and checking the reservoir for rust or corrosion.
 The points which were inspected in the Hydraulic Pack were:
 Condition of Breather cap
 Condition of Oil filter
 Oil Level
 Pressure Gauge Reading
 Pipe Leakage
 Overall condition of Hydraulic Pack
The Inspection was then carried out for:
 Gear Box Oil level
 Presence of Asset code

TPM (Total productive maintenance)
In industry, total productive maintenance (TPM) is a system
of maintaining and improving the integrity of production and
quality systems through the machines, equipment, processes,
and employees that add business value to an organization.
TPM focuses on keeping all equipment in top working
condition to avoid breakdowns and delays in manufacturing processes.
PROCESSOF DOING TPM ON MACHINE
 During TPM several TPM tags were hanged on machine to
describe the fault.
 The defect is note down on the tag and then hanged on that
defective part.
 During TPM tagging we cover almost every defect either it
is very small.
 Then the maintenance team rectify the defect as soon as
possible.
 On the tag we write down the name of machine , location of
defect on the machine, date of detection of defect, name of
manager who detected the defect , and the description of
defect.
Machine before and after tagging of TPM
Fig 11: Tag usedfor TPM

24. 24
Objective of TPM
The main objective of TPM is to increase the Overall Equipment Effectiveness of plant equipment. TPM
addresses the causes for accelerated deterioration while creating the correct environment between
operators and equipment to create ownership.
The objective finally is to identify then prioritize and eliminate the causes of the losses. This is done by
self-managing teams that problem solve. Employing consultants to create this culture is common practice.
The eight pillars of TPM are mostly focused on proactive and preventive techniques for improving
equipment reliability:
 Focused Improvement
 Autonomous Maintenance
 Planned Maintenance
 Quality management
 Development management
 tool Management
 Training and Education
 Safety Health Environment

CONCLUSION
Its give me better honour and privilege to conclude the Project report on “STUDY OF TIMING GEARS
AND INSPECTION OF HYDRAULIC PACKS VIA TPM ” has been presented in a very concise and
lucid manner i indeed have given commitment to the development of my project.
The aim STUDY OF TIMING GEARS AND INSPECTION OF HYDRAULIC PACKS VIA TPM
is to get knowledge of all process occurs in this industry.
This project help me out to get a lot of information not only the processes occur in this line but also
different fields like inspection and quality control unit and it also tell me the human relationship which is
needed in Between managers, team leaders and employ of the company.
It also help me to get knowledge about the tools and there different-different properties and types.
Some new things which i learned from this company are
 Use of different –different gauges.

 How to inspect the job after each and every inspection

 How to manage the machine if there is any problem arises in the machine

 Tools specification and its inserts characteristics.

 How to manage the task in the given interval of time.
