Description
The 1625002361 is the Atlas Copco Motor Overhaul Kit for oil-injected screw compressors, the set that takes a motor through a full overhaul in one order. It carries ten pieces across nine positions: the two bearing positions, the two lip seals, the circlip, the cooling fan of the motor, the drain nipple, the bushing, the O-ring and the oil nozzle of the C106-C111 element class.
An overhaul is a different piece of work from a service. A service renews the parts a running motor wears, while an overhaul opens the motor fully and returns every position around the shaft to the state the machine was built with. The 1625002361 is built for the second kind of work, which is why its bill runs past the bearings and the seals.
This article sets out what the 1625002361 contains, where it goes beyond a service set, what each of its positions does in an oil-injected machine, how the overhaul is read from the machine before it is planned and how the order is confirmed.
What the 1625002361 Motor Overhaul Kit Is
The 1625002361 is a motor kit of the Atlas Copco parts programme, listed for oil-injected screw compressors. It gathers ten pieces of a motor overhaul in one carton, and item data puts that carton at 280 × 240 × 240 mm and 4.65 kg, with Belgium recorded as the country of origin.
The overhaul kit is the fuller of the two motor sets in the programme. Where a service kit covers the running parts of the motor, the 1625002361 adds the positions that are opened only when the rotor comes out: the bushing, the drain nipple, the O-ring and the oil nozzle that feeds the element. One order therefore covers a job that would take several lines on the parts desk.
An Overhaul Set, Not a Service Set
The distinction shows in the contents. A motor service on the same machine renews the bearings, the lip seals, the circlip and the fan, and it leaves the motor closed around the positions that are still within tolerance. The 1625002361 takes the same machine further and returns the oil side of the motor at the same time.
That step matters on an oil-injected compressor because the motor of the package shares its working environment with the oil circuit. The drain nipple and the O-ring of the 1625002361 sit on that side of the assembly, and the nozzle of the kit belongs to the element the motor drives.
Ten Pieces Across Nine Positions
The lines below are the contents of the 1625002361 as the parts store states them. Nine positions are listed, with the seal position carrying two pieces.
- ROLLER BEARING — 1 piece
- BEARING BALL — 1 piece
- SEAL LIP — 2 pieces
- CIRCLIP — 1 piece
- COOLING FAN OF MOTOR — 1 piece
- DRAIN NIPPLE — 1 piece
- BUSHING — 1 piece
- OIL NOZZLE C106-C111 ELEMENT — 1 piece
- O-RING 7.3X2.4 — 1 piece
The two bearing lines are the point of the overhaul. A roller bearing and a ball bearing in one set mean both bearing positions of the motor shaft are renewed in the same visit, one carrying the radial load of the rotor and the other locating the shaft along its axis.
Where the Overhaul Kit Goes Beyond a Service
Four positions of the 1625002361 are the ones a service set does not carry. Each of them belongs to the oil side or to the shaft location of the motor, and each one is reached only with the rotor out of the housing.
The Oil Nozzle for the C106-C111 Element
The nozzle in the bill of the 1625002361 is named for the C106-C111 element class. It is the jet that delivers oil into the compression chamber at the point the element needs it, and the bore of that jet is what sets the oil the element receives at each turn. The naming of the part places the overhaul with the machines built around those element sizes.
A nozzle is a small part on a large job, and it is the reason an overhaul set is worth ordering as a set. Oil that arrives at the wrong rate leaves the element short of its film or carries more oil into the air path, and neither condition shows until the machine is running again. Renewing the nozzle with the bearings of the 1625002361 keeps the element and the motor on the same new clock.
The Drain Nipple and the O-Ring
The drain nipple of the 1625002361 is the part that lets the condensate and the settled oil leave the position it serves. Its bore is small and its seat has to stay tight, because a nipple that weeps puts oil where the motor and the frame around it should stay dry.
The O-ring 7.3 × 2.4 of the kit is the seal of that position, and the two parts are renewed together for the reason the whole kit exists. An old ring under a new nipple seats to the shape of the old part, and the joint returns to the same weep within a short time. The 1625002361 closes that circle in one fitting.
The Bushing Position
The bushing of the 1625002361 is the plain bearing that centres a rotating part in its housing. It carries the part at the point where the load is steady rather than fast.
The bushing position is a wear fit rather than a rolling element, so it is judged by clearance and by the marks of contact on its bore. The 1625002361 carries the position as a part of the overhaul set, which is what separates an overhaul from a renewal of bearings and seals on their own.
Motor Overhaul on an Oil-Injected Screw Compressor
The motor of an oil-injected screw package drives the element directly, so the load path runs from the coupling into the rotor and back through the bearings into the housing. An overhaul is planned around that path, and the 1625002361 supplies every position on it.
Why an Overhaul Is Scheduled, Not Waited For
A bearing does not fail without warning. It gives play at the shaft end, then noise, then a rising current at a duty the machine has always carried, and each of those steps appears in the readings long before the motor stops. The 1625002361 is planned against that trend rather than against a breakdown.
There is a second argument for planning the work. An overhaul opens the motor completely, so the cost of it sits in the stop and the labour rather than in the parts. Gathering the positions of the 1625002361 one at a time stretches the same stop over two visits, and a machine that runs between those visits runs on a partly renewed motor.
What the Overhaul Renews in the Motor
The overhaul returns the rotor to its centred position, renews the surfaces the shaft runs on and closes the motor at both shaft ends with new seals. On the oil side the 1625002361 renews the drain position and the nozzle that feeds the element, so the machine leaves the workshop with its motor and its oil supply to the element both restored.
The fan of the kit closes the circle. It is the part that keeps the housing cool, and a motor that has been overhauled runs at the load it was built for only when that cooling air is at its full figure.
Reading the Machine Before the Overhaul
The decision to overhaul comes from the record of the machine rather than from a single reading. The figures below are the ones a maintenance team writes on the sheet and reads again at the next interval.
Vibration, Current and Housing Temperature
Vibration measured at the motor housing is the first line of evidence, because a bearing that has begun to lose its surface raises the reading at the shaft frequency of the motor. A current that climbs at a duty the machine has always carried points at friction inside the motor, and a housing temperature above the norm of the machine points at the same place.
Recorded at a fixed interval, these readings become a trend, and the trend is what turns an unplanned stop into a planned one. The 1625002361 is ordered against that trend, with the overhaul slotted into a stop the plant has already planned.
The Element Side of the Same Job
The element shares the overhaul window, and the nozzle in the kit is the sign of it. Oil that has been delivered at the wrong rate leaves marks on the element, and the work of an overhaul is the natural moment to look at the chamber the nozzle feeds. The 1625002361 carries that position so the inspection and the renewal happen in one opening.
Grease and oil traces at the shaft ends and around the drain position belong on the same sheet. A lip seal that has begun to pass shows at the shaft, and a drain nipple that weeps shows at the frame below it, and both are positions the 1625002361 renews.
The Overhaul in the Workshop
An overhaul of a motor of this class is a workshop job, and the 1625002361 is laid out against the bill before the machine is stopped. The supply is isolated and locked off, the coupling is marked for the position it goes back in, and the motor comes off its mounting on the element housing.
Opening the Motor
With the motor on the bench, the ends are opened and the rotor comes out, and the bearing seats, the shaft ends and the bushing bore are measured before anything new goes in. A seat that has taken damage is corrected first, because a new bearing of the 1625002361 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 of the kit, and the shaft end is checked for the play the machine was built with. The fan goes on last, so its clearance at the cowl is set with the motor closed.
The Oil Side and the Element Nozzle
The positions that separate the 1625002361 from a service set are fitted at the same time as the shaft work. The bushing goes into its housing with the clearance the build calls for, the drain nipple and its O-ring close the drain position, and the oil nozzle goes back into the element side with a new jet.
The nozzle of the 1625002361 is fitted to the element the motor drives, so the work of the overhaul and the work on the element side share one opening of the machine. Nothing on that side is left for a second visit.
After the Overhaul
The readings taken before the overhaul are taken again after the first start. Current, vibration at the motor housing and housing temperature are the three figures worth writing down, because they are the baseline the next interval is read against, and the 1625002361 then runs as the reference the future readings are compared with.
Ordering the 1625002361 Through Seadweer
Motor kits are ordered by record rather than by appearance, because two kits of the same class can hold seals of different sections and elements of different sizes. The ordering routine of the 1625002361 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 overhaul. The team checks the record against the 1625002361 before the quotation is issued, and the element class of the machine is confirmed in the same pass.
What the Quotation Repeats
The quotation repeats the item data of the 1625002361: the ten-piece contents line, the box size, the weight, the country of origin and the tariff code. One confirmation covers the whole overhaul, so the workshop schedules the stop without a second enquiry for the individual positions inside the kit.

FAQ
What does the 1625002361 motor overhaul kit contain?
The kit lists ten pieces across nine positions: a roller bearing, a ball bearing, two lip seals, a circlip, the cooling fan of the motor, a drain nipple, a bushing, an oil nozzle for the C106-C111 element and an O-ring. One order covers the motor and the oil side of the overhaul.
How does the 1625002361 differ from a motor service kit?
A service kit renews the running parts of the motor: the bearings, the lip seals, the circlip and the fan. The 1625002361 carries those positions and adds the bushing, the drain nipple, the O-ring and the oil nozzle that feeds the element.
Which machines use the 1625002361?
The kit is listed for oil-injected screw compressors, and the element named in its bill places it with the machines built around the C106-C111 class. Send Seadweer the model and serial number, and the record confirms the fitment before the order.
Why renew the oil nozzle with the motor?
The nozzle sets the oil the element receives at each turn, and it is reached only with the machine open. Renewing it in the same stop as the bearings of the 1625002361 keeps the element and the motor on one new clock instead of two.
When should a motor overhaul be planned?
Watch the vibration at the motor housing, the winding current at a steady duty and the housing temperature of the machine. A trend that rises across intervals is the signal to plan the overhaul with the 1625002361 inside a stop the plant already has.
How do I order the 1625002361?
Send Seadweer the compressor model and serial number together with the part number you hold for the overhaul. The team checks the record against the 1625002361 before the quotation is issued, and the element class is confirmed in the same pass.

Bernard Otieno –
Our GA machine reached its overhaul point and the motor came off inside the planned window. The 1625002361 kit held every position we needed, from the bearings and the seals to the drain nipple and the nozzle for the element, so the job ran through without a parts call in the middle. Vibration at the motor housing came back to the level we record on a fresh machine, and the compressor has held its duty since.
