REPAIR INDICATORS FOR ENGINES

All power train components give off indicators. Some are good and some are bad. The important question is - is your maintenance program detecting these indicators before a catastrophic failure takes your equipment off the job and into the shop?Below list 2 types of indicators: problem and planned.Problem Indicators - As the name implies, by the time these indicators occur, you may already have a problem. The key is to diagnose the situation before it gets worse.

Engine Warning Signs and Possible Causes:-

Excess black smoke at full load (hot, unburned fuel):

• Dirty primary / secondary air cleaner
• Operating in too high a gear
• Overfueling
• Overloading
• Faulty turbocharger

Blue smoke (oil consumption):

• Hours on engine
• Worn rings/liners
• Worn turbocharger seals
• Worn valve products

White Smoke (steam: water in combustion chamber or start-up: unburned fuel):

• Leaking head gasket
• Cracked head and/or liners
• Faulty injector
• Incorrect starting procedure
• Incorrect fuel injection timing
• Low quality fuel

Increased oil consumption/excess blow-by

• Hours on engine
• Worn or broken rings/liners
• Worn turbocharger seals
• Worn valve guides

Unusual noises:

• Malfunctioning fuel nozzle/injectors
• Worn piston pin bushings
• Worn rod/main bearings
• Malfunctioning turbocharger
• Too much valve lash

Lack of power:

• Dirty air cleaner
• Dirty fuel filter
• Incorrect adjustment of governor linkage
• Malfunctioning fuel nozzles/injectors
• Slipping torque converter
• Improper set point• Low quality fuel

Increased fuel consumption:

• Fuel leak
• Dirty air cleaner
• Malfunctioning turbocharger
• Malfunctioning fuel nozzles/injectors• Improper set point
• Incorrect machine operation

Overheating:

• Plugged radiator core (external and internal)
• Incorrect adjustment or worn belts/pulleys
• Low coolant level
• Malfunctioning temperature regulators and indicator senders (symptom)
• Dirty air cleaner• Incorrect operator technique
• Slipping torque converter

Hard starting (Engine miss-firing):

• Worn fuel injection pump
• Improper starting technique
• Low quality fuel – high sulphur, low cetane rating or water in fuel
• Malfunctioning fuel nozzles/injectors
• Low cranking speed

Oil level over full:

• Coolant/fuel leakage into crankcase
• Improper oil fill

Debris in oil filter:

• Dirt entry
• Damaged bearings
• Coolant/fuel leakage into crankcase
• Extended oil change period
• Incorrect oil used.

Planned indicators are generally associated with a proactive, before-failure maintenance management program.
