Atlas Copco 1092001243 Motor Service Kit GA 15-22

Description

The 1092001243 is the Atlas Copco Motor Service Kit for the GA 15-22 oil-injected screw compressor series, the set that renews the parts a motor service takes out: two bearings, two lip seals, the circlip that retains the bearing and the cooling fan of the motor. It is a six-piece kit, and it covers the motor side of the machine in one order.

A motor in this class runs for years, and the work inside it follows condition rather than a fixed hour count. The kit exists as a set for that reason. When the motor of the machine comes off for a bearing, the seals and the circlip sit open to view at the same positions, so a renewal that leaves them behind returns to the same bench a few thousand hours later.

This article sets out what the 1092001243 contains, what each component does inside the motor, which numbers the components carry, how the fitment follows the GA 15-22 class and how the order is confirmed before it leaves.

What the 1092001243 Motor Service Kit Is

The 1092001243 is a service kit of the Atlas Copco motor programme, listed for the GA 15-22 oil-injected screw compressor series. The kit gathers six components of the motor service in one box, so the workshop holds what the job asks for at the moment the motor is opened. Item data puts the packed kit at 265 × 265 × 126 mm and 1.47 kg.

The number is the line the planner carries. A kit of this kind is ordered by part number against the machine record, not by the size of the box or by the look of the parts inside it, because two kits of the same class can hold seals of different sections. The 1092001243 is the number that matches this motor build.

A Kit Rather Than a Single Part

Buying the six components one at a time is possible, and it is how a motor service is often planned at short notice. The single-part route takes longer at the desk and at the bench, because five positions have to be traced and each one carries its own number in the parts book. The 1092001243 collapses that list into one line and one carton.

There is a technical argument behind the packaging as well. The bearings and the seals inside one motor work as a set: a new bearing running against a shaft end that still carries an old seal wears the seal lip, and a fan that has lost its balance loads the bearings it cools. The 1092001243 keeps the wearing parts of that service on the same clock.

The GA 15-22 Class in the Designation

The GA 15-22 in the name of the 1092001243 is the compressor class the kit is built for, the GA series machines of that output band. The motor of such a machine sits on the element housing of the package, and the shaft, the bearing seats and the fan of that motor build are what the kit is dimensioned against.

Fitment therefore runs through the machine record. The model and serial number of the compressor settle which motor build sits on the machine, and the record of that build settles the kit. Seadweer checks both against the 1092001243 before the order is confirmed.

What the 1092001243 Contains

The official bill of the 1092001243 lists six pieces across five positions, and every position belongs to the motor service. The lines below are the contents of the kit as the parts store states them.

• LIP SEAL — 2 pieces
• BEARING — 2 pieces, listed as two positions
• CIRCLIP 42 — 1 piece
• COOLING FAN — 1 piece

The count is worth reading twice, because the two bearings and the two lip seals are what make the 1092001243 a complete motor service rather than a partial one. One bearing position serves each end of the shaft, and one lip seal closes each of those ends.

The Two Bearings

The bearings of the 1092001243 carry the rotor shaft of the motor at its two ends. The drive end takes the load that the coupling and the element put on the shaft, and the opposite end holds the shaft in line with the housing bore. Between them they fix the position of the rotor inside the stator, and that position is what keeps the air gap even around the circumference.

A bearing that has run its life announces itself in steps. Play at the shaft end grows first, then the noise of the motor changes, and the current of the machine reads higher for the same duty. The 1092001243 renews both bearing positions in one pass, which is the point of the pair in the kit.

The Two Lip Seals and the Circlip

The lip seals of the 1092001243 close the motor where the shaft leaves the housing, one at each end. Their job is to keep the inside of the motor clean and to hold the bearing grease on the seat it was packed with. The lip of such a seal runs against the shaft surface as the hours build, and that wear is the reason the pair is renewed with the bearings.

The circlip 42 of the 1092001243 is the retaining ring that holds a bearing in its seat. The 42 in the designation is the size of the position it sits in, and the part is the smallest item in the kit and the one that stops the bearing from walking in its housing.

The Motor Cooling Fan

The cooling fan of the 1092001243 is the part that moves air across the motor housing while the machine runs. A motor of a GA 15-22 package is cooled on its own circuit, separate from the compression air path, and the fan on the shaft is what keeps that air moving. Winding temperature stays in band as long as the fan holds its shape and its balance.

The fan in the kit is the position that ages quietly. Blades that have taken heat and a hub that no longer runs true both cut the air the motor receives, and the effect shows up as a hotter housing at the same load. Renewing the fan with the bearings of the 1092001243 restores the cooling circuit of the motor at the same time as its running surfaces.

Component Numbers That Travel With the Kit

Some parts of the 1092001243 are listed in the parts programme in their own right, so they carry their own numbers beside the kit number. The lip seal position of the kit is the kit lip seal 1616574280, and the bushing 1622000900 is another part of the kit. Both are recorded with their own origin and tariff data, and both travel with the papers of the kit.

The kit lip seal 1616574280 is the current version of that seal position. The record names 1616574200 and 1626361500 as the numbers it replaces, so a file that still shows one of the older numbers leads to the same seal, and the position is ordered under 1616574280. The bushing 1622000900 is a part of the kit, the plain bearing that centres the rotating part in its housing.

When the Motor Comes Off

A motor service is planned from condition, and the evidence sits in the instruments of the machine and in the sound of the motor housing. The signs below are the ones that send a workshop to the 1092001243.

Readings That Point at the Bearings

Vibration measured at the motor housing is the first line of evidence. A bearing that has begun to lose its surface shows a rise at the shaft frequency of the motor, and the rise stays in the reading while the load of the machine is steady. Recorded at a fixed interval, that reading becomes a trend, and the trend is what turns an unplanned stop into a planned one.

Two more readings follow the same story. Winding current that climbs at a duty the machine has always carried points at friction inside the motor, and a housing temperature that sits higher than the machine’s own norm points at the same place. Either reading is a reason to open the motor and plan the renewal with the 1092001243.

Readings That Point at the Seals and the Fan

The seals and the fan leave different traces. Grease at the shaft end, dust drawn into the housing and a dark ring on the shaft where the lip runs all point at the seal positions of the 1092001243. On the fan side, a blade that has taken heat, a crack at the hub or a fan that no longer sits square on the shaft shows at the first inspection with the cowl off.

None of these signs stops the machine on the day it appears. The value of reading them early is that the motor is opened on a planned stop, with the 1092001243 already on the bench, instead of in the middle of a production week with the machine down.

Handling a 1.47 kg Kit

The packed 1092001243 weighs 1.47 kg in a box of 265 × 265 × 126 mm, so it is a bench-top carton that stores in the maintenance room without special conditions. The six pieces are laid out and checked against the bill before the motor comes off, which is the step that confirms nothing is missing while the machine is still closed.

A kit of this size suits a plant that runs several GA machines, because the same carton covers the motor service of every machine in the class. One line on the spares list and one carton in the workshop keep the service ready through the year.

Fitting the Motor Service Kit

The motor service of a GA 15-22 machine is a workshop job, and the 1092001243 arrives complete for it. The machine is stopped and made safe, and the motor is taken off its mounting on the element housing before the shaft end is opened.

Before the Motor Is Lifted

The first step belongs to the plant rather than to the kit: the supply is isolated and locked off before the terminal box is opened, and the fan is left to come to a stop. The coupling and the shaft end are marked for the position they go back in, and the motor is lifted clear with the lifting points the housing carries.

On the bench the motor is opened at the ends, the rotor comes out, and the bearing seats and the shaft ends are measured before the new parts of the 1092001243 go in. A seat that has taken damage is corrected first, because a new bearing fitted into a worn housing returns the same noise within a short time.

Assembly follows the reverse order with the new bearings, the new lip seals and the circlip from the 1092001243, and the fan goes on last so the balance and the clearance at the cowl are set with the motor closed.

After the First Start

The readings taken before the service are taken again after the first start. Current, vibration at the housing and housing temperature are the three figures worth writing on the service sheet, because they are the baseline the next interval is read against. The motor of the machine then runs with the air gap, the seals and the cooling air of the 1092001243 all renewed in one visit.

Ordering the 1092001243 Through Seadweer

Kits of the motor programme are ordered by machine record rather than by the appearance of the parts, because two kits of the same class can hold seals of different sections. The ordering routine of the 1092001243 is built around that fact.

What to Send with the Enquiry

Send Seadweer the model and serial number from the compressor nameplate, together with the part number you hold for the motor service. The team checks the record against the 1092001243 before the quotation is issued. A file that still shows 1616574200 or 1626361500 for the lip seal position is resolved in the same pass, and the order is confirmed under the numbers that are current.

What the Quotation Repeats

The quotation repeats the item data of the 1092001243: the six-piece contents line, the box size, the weight, the country of origin and the tariff code. One confirmation covers the whole motor service, so the workshop schedules the work without a second enquiry for the individual positions inside the kit.

FAQ

What does the 1092001243 motor service kit contain?

The kit lists six pieces: two lip seals, two bearings, one circlip 42 and one cooling fan of the motor. That set covers the five positions a motor service takes out on the GA 15-22 build.

Which machines use the 1092001243?

The kit is listed for the GA 15-22 oil-injected screw compressor series, and the motor build of that class is what it is dimensioned against. Send Seadweer the model and serial number from the machine, and the record confirms the fitment before the order.

Which part numbers sit inside the 1092001243?

The kit contains the lip seal 1616574280, which is the current version of 1616574200 and 1626361500, and the bushing 1622000900. Both are parts of the kit and travel with its papers.

How do I know the motor needs a service?

Watch the vibration at the motor housing, the winding current at a steady duty and the housing temperature of the machine. Grease at a shaft end or a fan that no longer runs true point at the other positions of the 1092001243, and an inspection with the cowl off settles it.

Is the 1092001243 a complete motor service?

Yes. The two bearings serve both ends of the rotor shaft and the two lip seals close both of those ends, with the circlip holding the bearing in its seat and the fan restoring the cooling air. One order covers the motor side of the machine.

How do I order the 1092001243?

Send Seadweer the compressor model and serial number together with the part number you hold, and the team checks the record before the quotation is issued. If your file shows an older lip seal number, the check resolves it in the same pass.
