This manual is designed to be of assistance to
all personnel concerned with the maintenance
and overhaul of the SIMPSONS Diesel Engine.
It presents a complete and detailed description
of the engine, together with precise instruction
on servicing and overhaul procedure and
dimensions which should be closely followed
when overhauling any part of the engine to the
Manufacturers standards.
Effective maintenance can only be carried out if
thepersonnelconcernedarefullyconversantwith
the various components of the engine. Before
maintenance operations are commenced, this
manual should be carefully studied, and it should
at all times be kept where it will be needed in the
FOREWORD
workshop.

SAFETY
The safety measures that always should be performed in
order to avoid risks that is always present.
All servicing normally be carried out with the engine
stationary.
Do not approach the running engine with loose cloth
or long hair.
Be careful of hot surfaces.
Do not open the radiator filler cap when the engine is hot.
Avoid skin contact with oil, fuel or chemicals that can
cause burn. Long term contact with oil can lead to the
skin problem.
Run the engine only in a well-ventilated area.
When lifting the engine use the lifting eyes that are fitted
to the engine.
Never work alone when removing heavy parts.
When cleaning the engine with high-pressure water,
never direct the jet at seals, rubber hoses or electrical
components.
Always prevent diesel or oil from contacting rubber parts
or tubing
Caution: Warns of a risk of injury, serious damage to
the product or serious malfunctions could occur if the
instruction is not followed.
Important: Is used to draw attention to things that could
cause damage to or malfunction of the product.
Note: It is used to draw attention to important information
to facilitate procedure or handling.
TOOLS AND MEASURING EQUIPMENT
Be sure that all necessary tools and equipments are
available before starting work.
Use special tools where they are specified.
Never drop the tools
Use correct tools as specified.
REMOVAL OF PARTS:
First find the cause of the problem and then determine
whether removal or disassembly is required before
starting the job.
INSPECTION OF PARTS:
Eachpartwhen removedshould becarefully inspectedfor
malfunction, deformation, damage and other problems.
All disassembled parts required for reassembling should
be carefully stored.
Ensure to separate and correctly identify the parts to be
replaced from those that will be used again.
CLEANING OF PARTS FOR REUSE:
All parts to be used again should be carefully and
thoroughly cleaned by an appropriate method.
PARTS
When replacing parts, use genuine SIMPSON parts.
Oil seals, Gaskets, O-rings, Lock washers, split pins and
plastic nuts should always be replaced with new ones.
Standardvaluessuchas torqueandadjustments mustbe
strictly observed in the reassembly of all parts.
FITMENT
Use correct tools, gauges and testers for correct fitment
of the parts to standard value.
ELECTRICAL SYSTEM
Be sureto disconnectthebattery cablesfromthe negative
terminal of the battery
Never pull on the wires when disconnecting connectors.

OPERATION AND MAINTENANCE
PREPARATION FOR STARTING
Check the coolant level with radiator.
Check the oil level in engine sump.
Check the fuel oil level in the tank
Check the battery is fully charged and that all electrical
connections are properly made and all circuits in order.
STARTING THE ENGINE
Turn starter switch in clockwise direction to the “ON”
position and then to start position
As soon as the engine starts, release the switch to the
“ON” position.
TO STOP THE ENGINE
1.Pull the stop control knob and hold until the engine
ceases to rotate.
2. Push and ensure the stop control knob returns to the
run position.
3. Turn start switch to the ‘Off’ position.
Note: Where an electrical shut off solenoid is provided,
turn the start key to “Off” position to stop engine.
Always be sure that the starter pinion has stopped
revolving before re-engaging the starter.
RUNNING-IN PROCEDURE
It is not necessary to gradually run-in a new engine and
any prolonged light load running during the early life of
the engine and in fact prove harmful to the bedding in
of piston rings and liners.
Full load can be applied on a new engine as soon as the
engine is used, provided that the engine coolant is first
allowed to reach a temperature of at least 140oF (60oC).
POST-DELIVERY CHECKOVER
After a customer has taken delivery of his diesel engine, it
isadvisable, ageneral check-overof theengine becarried
out after the first 25 hours in service.
It is also recommended that the following procedure
be adopted where an engine has been laid up for a
considerable period before it is again put into service.
1.Drain lubricating oil sump and re-fill up to the full mark
on the dipstick with new clean oil (Do not overfill).
2. Renew the lubricating oil filter (canister).
3. Check external nuts for tightness.
4. Check/ adjust valve tip clearances to 0.15 mm (0.006’’
to inlet and exhaust valve in cold.
5. Check fuel pipes from tank to fuel injection pump for
leaks.
6. Check for lubricating oil leaks and rectify if necessary.
7. Check hose clips for tightness.
8. Check cooling system for leaks and inspect radiator
water level.
9. Check fan belt for tension.
10.Carryouttestto checkgeneralperformanceofengine.
11. Check engine mounting bolts for tightness.
12.Checkthe electricalequipmentsuch asrateofcharge,
effectiveness of connections and circuits, etc.
Thereaftermaintenanceperiods shouldbe inaccordance
with the instructions given. (Ref. Section E).
PRESERVATION OF LAID-UP ENGINES
It is recommended that the following procedure
be adopted and applied immediately the unit is
withdrawn from service:
1. Thoroughly clean all external parts of the engine.
2. Run the engine until well-warmed. Stop the engine
and drain lubricating oil from sump. Remove the oil filter.
3. Drain coolant from radiator and engine cylinder
block.
4. Replace the oil filter, fill sump to correct level
with clean, new lubricating oil or with a suitable
preservative fluid.
5. Remove atomisers and spray into cylinder bores
100 ml of lubricating oil divided between the
cylinders.
6. Turn engineslowly overcompressionand replace
atomisers.
7. Remove air cleaner intake pipe and Remove
exhaust pipe and seal opening in manifolds.
8. Disconnect battery and store in fully charged
condition. Before storing the battery, terminals
should be treated to prevent corrosion.
The fuel system be drained or charged with a suitable
preservative designed for the prevailing climatic

18
SC213 Diesel Engines
conditions or alternatively, it may be left primed with
normal fuel oil.
If the engine is laid for several months then the fuel oil
contained in the remainder of the fuel system should
also be dispelled and the fuel filter renewed, following
which the system may then be recharged with fresh
clean fuel oil.
Before starting, the engine should be cranked over by the
starter motor with the stop control in the ’off’ position
until oil pressure is recorded or the oil warning light is
extinguished. Do not rapidly accelerate the engine after
initial start; allow it to run at slow speed for approximately
two minutes to ensure good oil circulation before
accelerating to higher speeds.
Note: Where a preservative is used in the lubricating oil
sump, this should be drained off and replaced by normal
lubricant prior to restarting the engine at the end of the
storage period.
FROST PRECAUTIONS
Precautions against damage by frost should be taken if
the engine is to be left exposed to inclement weather
either by adequately draining the water system or where
this is not convenient an anti-freeze of reputable make
and incorporating a suitable corrosion inhibitor may be
used.
The coolant solution containing 25 per cent anti-
freeze manufactured to BS 3151 in water in a properly
maintained engine should maintain its anti-freeze and
anti-corrosive properties throughout the winter season
and in general, a safe life of 12 months may be
reasonably expected.
Remove the radiator pressure cap, drain the cooling
system by opening the radiator drain tap and the cylinder
block drain tap.
When draining the cooling system ensure that the engine
is in level.
Operatorsare advisedto takeprecautions whenoperating
in temperatures below freezing point:
1. Before starting the engine, turn the fan and water
pump by hand. If freezing has taken place, this
should free any ice formation.
2. If it is impossible to turn the pump by hand, the
radiator and engine should be filled with warm
water.
After an anti-freeze solution has been used, the cooling
system should be thoroughly flushed in accordance
with the manufacturer’s instructions before refilling with
normal coolant.
