ENGINE DISMENTLING

Mount engine on the work stand. Drain engine

oil is not drained while removing engine from the

vehicle remove the air cleaner.

Disconnect & remove the fuel pipe from the

feed pump to filter & from the fuel filter to the fuel

injector pump. Remove the fuel filter assembly.

Remove the air Compressor inlet house from the inlet

manifold.

PISTON CONNECTING RODPISTON- Piston is considered to be most important

part in a reciprocating engine in which it helps to

corner the chemical energy obtained by the

carburetion of fuel into useful mechanical power.


7/12

That material is aluminums Alloy & Cast iron.

Pistons are usually in diameter then the bore of

the cylinder & which is called the piston clearance.

Its Parts are following. 1. Comp. Ring

2. Oil Controlled Ring

3. Piston Pin

4. Connecting Rod

5. Crank Shaft

6. Fly Wheel

7. Valves

8. Cam-Shaft

9. Engine Assembly

AIR COMPRESSOR

The air compressor is reciprocating motion

piston type with train in the tin cylinder & driven

from camshaft operating test with compressor

running check for noisy operation & Oil leakage.

In the engine other parts are following.

JOINTS

There are some metal joining process in this process

some are Hear Following.

UNIVERSAL JOINT:- It is used to make a flexible

connection between two rigid shaft at an angle with

each other. It transmits the power net only at an

angle but also while this angle is boiling carried

constantly cross type universal joint is used in

Leyland.

SLIP JOINT:- In this Leyland vehicle the slip joint is

mounted in U.J. of propeller shaft. The slip joint hasoutside spleens one shaft & machining internal

spleens on a mounting hollow shaft. The Spleens

Causes the shaft to rotate on. The Spleens causes

the shaft to rotate on array from the vehicle frame

this joint incorporated between the propeller shaft &

the U-Joint.

WHEELS & TYRES

The power developed by the engine has been


10/12

transferred through the clutch, gear box, propeller

shaft & diff. to the rear axle, wheels are connected to

the rear axles as the rear axle turns, wheels also turn

& vehicle moves on the road. The ultimate purposeof the power developed by the engine is to turn the

wheels so that vehicle moves on the road.

There is a Tyre recovery shop to when the Tyre

is full of wear and not a work sufficiently, thane a

plate of rubber and place of Tyre by full steam

pressure by using of boiler.

CHASIS & FRAME

DATA:- Side member & Cross member: Channel

Section

Size: Width (mm): 762(3)

Depth (mm): 228.6(9)

Thickness (mm):

635(0.25)

DISCRIPTION:- The frame comprised of two parallel

side members built up with riveted cross member &

buts. The chasis identification is fixed to the side


11/12

member mid way between the axles on account

these plates should be replaced. To check the

alignment of the frame runs the vehicle on to the

hard level floor. Tester piece of paper on the floorunder each paints A As shown in fig. with plant lab

& line projects.

BODY BUILDING:-Give below is some of the

important paints to be taken neat of white mounting

bodies on the chassis.

The body cross member should be fitted on

the long member by U bolts should be suitable

speed the U bolts should be inter passed with

supporting metric space between top & bottom

flange of the side member to prevent distortion when

the U bolts are tighten. Dont use spaces made of

wood because of this is likely to shrink & drop out. If

would of this is be advisable packing piece for the

V clamp in order to prevent distortion of chassis

side.

It extra drill holes are drilled case should be

taken to drill all the new holes.

If the vehicle is working very bad condition

which required additional reinforcement of the from

approved should be obtained.

Bolt the fitches to the frame by additional bolts

& nuts using the existing holes on the frame.

MACHINING PARTS

In the work shop there are some of the

machines for the cutting, finishing, gladding,

threading, to the work piece on the machine of Lath,

Drilling, Threading, Milling, Cutter, etc. for making

the good material and good services for machining

the piston cylinder and engines some of parts made

by the machines.

It will be really useful to us and other people for

transportation to one place to another and it is really

great work for Gujarat.
