1 GENERAL INFORMATION
1.1 Installation
1. The um unit and its associated base late or
trolley mounting should be ositioned on a firm
horizontal latform, and in the case of ortable
units restrained from accidental movement.
2. If the um is fitted with ush-on ty e suction and
delivery s igots the hoses must be firmly secured
on these s igots with heavy duty clam s or cli s
ca able of withstanding the system o erating
ressure.
3. The integrity of the hose clam ing arrangements
should be checked at regular daily intervals in the
case of static installations or whenever the um
is re ositioned in the case of ortable units.
4. Similar recautions should be taken with clam s
securing multi le lengths of hose on installation
where long delivery and suction lines are involved.
5. Delivery hose and any associated i ework
should be ca able of withstanding the maximum
system o erating ressure. Suction hose should
be of the non-colla sible variety.
1.2 Operation
1. The um should only be o erated within the
s eed and ressure limits detailed in the o erating
handbook for the model in question.
2. If there is a danger of freezing, the fluid normally
retained within the um between o erating
cycles should be drained off through the drain ta s
rovided.
3. Where rotective ca s are used to revent
damage to the suction and delivery s igots during
storage or in transit they must be removed before
the um is started u .
1.3 Maintenance
1. Ins ection and maintenance rocedures are
detailed in the o erating and servicing manual for
the model in question.
2. Re lacement arts. Only the manufacturers or
factory a roved com onents should be used as
re lacement arts and where necessary they
should be fitted with the assistance of the s ecial
ur ose tools indicated in the o erating and
servicing manual.
3. All maintenance work must be carried out with the
um and engine/motor stationary.
1.4 I.C. Engines
1. Where I.C. engines are used to ower the um
they have been mounted in accordance with the
engine manufacturers recommendations and
adequate guarding rovided between the um
and engine.
2. Exhaust and Exhaust Pipes. If there is a risk of
accidental contact by o erators, the exhaust
system should be lagged or screened and the
outlet directed away from o erators or other
ersons likely to be nearby. Direct contact with
flammable materials of all ty es must be avoided.
The im ortance of adequate ventilation to ensure
removal of exhaust fumes when engines are
o erated in enclosed or covered accommodation
cannot be over-stressed. Engines should not be
run in hazardous ex losive atmos heres.
3. Access and Operation. Ensure that the o erator
can start, control and sto the engine easily by
making all controls readily accessible. Fit remote
controls if access is difficult. Follow the
instructions laid down in the Engine
Manufacturer's O erators Handbook for starting,
o erating and sto ing rocedures.
4. Fuel. In addition to the fire hazard associated with
fuel and lubricating oils, reventative action is
necessary with res ect to leakage, contamination
and bodily contact.
5. Electrical Connections. It is essential that earth
terminals are connected with an absolutely sound
earth oint and care should be taken to ensure
that the correct sized conductors are selected to
suit the current and distance to be carried.
1.5 Fitting Instructions or
Centa lex Couplings (Diesel
Engines)
IMPORTANT NOTES – OBSERVE STRICTLY:
The Centaflex Cou ling Assembly is su lied in a re-
assembled state and must be fitted to the um drive
shaft and engine flywheel in this state. On no account
should any of the com onents that make u the
cou ling assembly be dismantled unless it has become
necessary to service one of the com onent arts.
Ty ically, the most likely com onent to require
re lacement will be the rubber element and servicing
of this item is ex lained in Section 1.5.3 below.
The cou ling assembly consists of a central steel hub
whose outside diameter locates within a bore of a
rubber element and is secured within the element
using three ca screws that ass radially through its
outer diameter. In turn, the rubber element locates
onto three horizontal ins, equally dis osed on a PCD
and each secured to the face of a steel ada tor late
with ca screws. The ca screws securing both the
central steel hub and the horizontal ins are torque
tightened to the values shown in the table in Section
1.5.2 below.

Selwood Seltorque S150 Manual
4
The rubber element itself is free to slide on the
horizontal ins. It is therefore unnecessary to remove
the ca screws that secure the ins unless the ins
themselves have become damaged.
1.5.1 Preparation o the Centa lex Coupling
or Pump Removal
NOTE: Before commencing, mark the osition of the
cou ling assembly on the um drive shaft. Pay
articular attention to the size of the ga between the
back of the rubber element and the face of the steel
ada tor late. This ga has been factory set and is
maintained when the setscrew in the steel hub is
locked in osition.
1. In order to allow the um drive shaft to be
withdrawn from the steel hub of the cou ling, it will
be necessary to loosen the setscrew located in the
outside radius of the steel hub just in front of the
rubber element. The setscrew clam s the
cou ling assembly onto the to of the um drive
shaft key and it is not necessary to com letely
remove this screw.
2. Once the setscrew is loose the um drive shaft is
free to be withdrawn from the hub of the cou ling.
Note too that when the setscrew is loose the
cou ling assembly is free to slide in either
direction onto the um drive shaft or onto the
horizontal ins.
1.5.2 Centa lex Coupling Assembly
Sequence
1. The radial and axial screws connecting the rubber
element to the hubs must all be tightened to the
torque given in the table below, using a torque
wrench.
Tightening Torque
Centa lex
Size
Screw
Size Nm mK
16/22 M12 85 8,5
25/28 M14 140 14
30 M16 220 22
2. Tightening with a torque wrench is articularly
im ortant. Tightening by feel will not do as
ex erience has roved the tightening torques in
such cases are far too low. Tightening torques
which are too low will inevitably lead to slackening
of the screws in service and consequently to the
destruction of the cou ling.
3. Ensure that on tightening the screws, the
aluminium bushes in the rubber art are not
twisted at the same time, but sit straight. In order
to reduce friction between the screw head and the
aluminium art, a small amount of grease should
be a lied under the head of the screw before
fitting.
4. If necessary, use a suitable tool for a lying
counter ressure on the element to revent
twisting of the rubber art during tightening of the
screws. This is articularly im ortant with radial
screws, otherwise the cylindrical faces between
the aluminium insert and the hub will not engage
on the full area, but only on two corners. This will
inevitably lead to slackening of the screws and
subsequent destruction of the cou ling. If the
cou ling is su lied in a re-assembled state do
not dismantle it, but fit it in this condition.
1.5.3 Replacement o the Steel Hub and
Rubber Element
NOTE: Once the Centaflex cou ling has been
re ared in accordance with Section 1.5.1 above, it is
free to be removed from the horizontal ins on the face
of the ada tor late.
1. If it becomes necessary to re lace either the steel
hub or rubber element, the three radial ca s
screws must be removed in order to se arate the
two com onents. When removing these ca
screws it is recommended that the cou ling
assembly remain on the horizontal ins for ease of
their removal.
Once the three radial screws are removed, the steel
hub can be se arated from the rubber element.
Also at this stage the rubber element can be
removed from the horizontal ins of the ada tor
late.
3. Re lace the rubber element and/or steel hub as
necessary to refurbish the assembly.
4. Fit the rubber element onto the horizontal ins of
the ada tor late.
5. Insert the steel hub into the centre of the rubber
element and align the radial mounting holes with
ta ed holes in the hub.

Selwood Seltorque S150 Manual

6. Fit the three radial ca screws in accordance with
the instructions at Section 1.5.2.
7. The cou ling assembly is now re ared for the
re lacement of the um .
8. Once the um drive shaft is engaged in the
cou ling hub bore, set the osition of the cou ling
assembly to that reviously marked when Section
1.5.1 was erformed.
9. Tighten the setscrew that locks the steel hub of
the cou ling assembly to the um s drive shaft
key.
1.6 Electric Motors
1. All electrical connections should be made through
adequately rated conductors and starters.
Isolators and other associated switchgear should
be of adequate ca acity for the im osed ower
loadings. All electrical equi ment should be
adequately earthed.
2. Isolate the ower su ly before carrying out any
commissioning, servicing or maintenance work on
the um or electric motor.
3. Where electric motors are to be o erated in
hazardous or ex losive atmos heres they should
be of the flame roof enclosure ty e a ro riate to
that atmos here.
You are requested to take such ste s as are
necessary to ensure that this information is made
available to all those involved with the use of our
roducts. This information must be made available not
only to your own em loyees at their work lace, but
also to anyone who may urchase or otherwise
acquire (hire) such roducts for use in his own
work lace.
It is our intention constantly to review our obligations
under the Act and we will be issuing from time to time
further information with regard to the safe a lication,
use, ins ections, and service associated with our
roducts.
1.7 Fitting Instructions or Fenner
Couplings (Electric Motors)
1. Adjust osition of um on chassis until the inside
faces of the cou ling flanges are arallel to each
other. The distance between the faces should
measure from 24 to 29mm (15/16” to 1 1/8”).
Whilst adjusting the um ’s osition, it is also
necessary to achieve alignment of the shaft
centre-lines within 1.5mm (1/16”) of each other by
laying a straight edge cross the two flanges at
several ositions around their circumferences.
Fully tighten the nuts immediately the cou ling
flanges are correctly aligned. Recheck alignment
after tightening.
2. The flexible cou ling assembly should now be
com leted. O en-out the tyre and fit over the
cou ling flanges ensuring the tyre beads seat
ro erly on the flanges. To ensure ro er
seating, it may be necessary to strike the outside
diameter of the tyre with a small mallet. When
seated there should be a ga between the ends of
the tyre of about 1/8” (3mm). Tighten clam ing
ring screws in flange alternately and evenly
(a roximately half a turn er screw) working
round the flange until 17lbf ft (2.35kgf m) torque is
achieved.

2 ROUTINE MAINTENANCE
Lack of routine maintenance is the most frequent
reason for the breakdown of um s. We earnestly
advise users to ensure that at least the following
actions are taken.
1. Check these three oil levels daily:
a) Engine oil.
b) Bearing housing oil.
c) Flushing chamber oil.
2. Always drain water from the um in cold weather
when it is not running. Drain:
a) Pum body.
b) Delivery valve chamber.
c) Both sides of air um (4 drain ta s if twin
rime).
3. Do NOT run the um if significant quantities of
water esca e through the exhaust valve of the air
um . This um is designed to handle moisture-
laden air, but not to um a high ercentage of
water. Refer to servicing instructions for further
advice.
4. Do NOT run the um if malfunction is sus ected
in any of its arts. In articular, it must
immediately be serviced if the level of oil in the
flushing chamber varies daily, or if the oil becomes
contaminated with the um ed fluid.
5. A hose strainer should always be fitted to the free
end of the suction line if there is a ossibility of
oversized solids entering the um . The
dimensions of rocks, ebbles, etc. must not
exceed 100mm (4"). Larger soft solids, however,
of the ty e found in abattoir duties, for exam le,
will ass freely through the um . Refer to
Selwood Ltd if in need of advice in this connection.
