498-1084 30 HRD060D Diesel Generator
Maintenance
With the left and right hand side panels removed
check that bulkhead plate that is bolted to the front
face of the engine is sealing against the sound
insulation of the side panels.
Check that the area around the fuel tank for signs of
damage or leakage.
General Inspections
Inspect generally for:-
Fuel and Oil Leaks: Look for excessive oil in the base
tray. Look for weeps from fuel hoses and connections.
Check the insulation is dry and not contaminated with
fuel or oil.
Worn or Failed Anti Vibration Mounts: When the
side panels are removed rock the engine and check
all four anti vibration mounts are exing slightly and
have not failed or broken up.
Damaged or missing insulation and seals:
Generally look at the sound insulation and seals and
check it is still securely tted and has not deteriorated.
Missing Safety Labels: These labels are a
mandatory safety requirement and if any are missing
or not easy to read they should be replaced. Full
details of all labels are contained in this manual. A
replacement label kit is available.
Chafng or Stretching of Cables: Inspect all cables
and connections and look for obvious signs of wear or
damage.
Correct sealing / tting of exhaust pipe: Remove
the top panel and check the exhaust pipe is correctly
tted and sealed at its mounting ange with no signs
of blowing.
Lifting Points: Inspect the lifting points for obvious
signs of wear, damage or distortion.
Signs of Over Heating: Look for obvious
deterioration due to heat and investigate the cause
and rectify as necessary.
Fuel Cap: Check the cap seals correctly. Check for
obvious signs of fuel spillage.
Electrical:
• Inspect sockets, and replace if damaged or
contact pins are burnt.
• Check all wiring is secure and not damaged.
• Check the output voltage and frequency are
correct.
• Check the earth continuity between the socket
earth pins and the generator frame.
Run on ¼, ½, ¾ then full load
Operating the generator at low load levels for
extended periods can result in high levels of carbon
build up in the engine and exhaust system which can
lead to excessive smoking, reduced efciency and
overheating. Looking at the silencer’s outlet will give
some indication this has happened.
After each service the generator should be run rst
on ¼, then ½, then ¾ and nally full load using a
load bank or a similar load like an electric fan heater,
to burn out any deposits of soot in the engine and
silencer.
Each level of load should be applied for at least
10 minutes or until the exhaust is clear of soot and
smoke. If you suspect the engine is badly sooted, DO
NOT apply full load but build the load up gradually.
It should be anticipated that hot soot will be expelled
from the engine during this procedure and it should be
done in a safe place away from combustible material
and under supervision at all times.
