Oil & Its leakage in Medium & Heavy Commercial Vehicle

Presented By:Name: Anjani KumarRegd.No:1001216141Semester: 7th Branch: Mechanical Engg.

Introduction

Oils are the major component of vehicle

Perform vital role as lubrication, energy production, heat reduction etc.

Brown/Black patch under the vehicle is the obvious sign of the Oil Leak in vehicle

Leakage in the vehicle will lead to malfunctioning and poor on road performance

Medium & Heavy commercial Vehicle

Need For Oil It lubricates moving gears and shaft

arrangementOils carries away heat generated inside

the engine and gear boxAvoid direct contact of different moving

surfacesActs as washing agent for dirt & used

grease provide smooth surfaceMaintaining wear and tear free

mechanism for long term use

Types of OilsEngine oil: 15W40Differential & Axel Oil: 

85W140. Transmission & Clutch Oil:

85W90Coolant oil: ETHYLENE

GLYCOL

Fuel oil: Diesel, Bio Fuels

Major points of leakages in M & HCVs

From Hydraulic pipe joint at steering box

From tilt pump bottom joint

From Hydraulic pipe(6’’) “T” joint:

From Hydraulic pump elbow union joint

Leakage from cab lifting cylinders

Oil leakage from cab lock union pipe joint

Oil leakage from fuel

tank welded jointOil leakage from

P.T.O. Pump

Oil leakage from

gear box drain plug

Oil leakage from steering box

Leakage of coolant Leakage from clutch housing

Reasons For Leakage

Worn pistons and ringsDamaged gasketsOil Drain plug not secured properlyOil plug damagedOil filter not attached correctlyHigh oil pressure Oil coolant line corroded Loosely fitted FastenersImproper Welded parts

Corrective Measures Fasteners should be properly tightened anti leak/sealant material over jointsReplacing damaged gasketApplying Teflon tapeTightening of oil drain plugs and oil

filtersReplacing the leaking parts like fuel

tank etc.Maintaining right oil level in the tank

or oil sump.
