Description
The 2901200616 is the Atlas Copco Motor Overhaul Kit for oil-injected screw compressors, listed in the parts programme as KIT MOTOR OVERHAUL FOR OIL INJECTED SCREW COMPRESSORS. The kit services the drive motor end on the GA VSD+ machines, and the official rebuild note places it with the 7, 11 and 15 kW drive motors of that range. It is a small set by compressor standards, and every part in it is a part that is reached when the motor is opened.
Atlas Copco recorded the note that carries this number for a defined group of machines. The 3IN1 connector fitted in production until 05/2014 is no longer delivered, and the machines move to the plastic connector through a defined rebuild. The 2901200616 is the motor overhaul kit named in that rebuild, alongside the stator, the top cover, the motor cable and the connector kit.
This article sets out what the 2901200616 contains, where it sits in the GA VSD+ range, what the connector rebuild involves, and how the order is confirmed with the machine record.
What the 2901200616 Motor Overhaul Kit Is
The 2901200616 is an exchange set for one motor overhaul, not a repair of a single failed part. An overhaul of this kind renews the bearing position and the complete sealing line of the motor in one stop, and the kit collects those parts under one number so the workshop does not assemble the set from loose items.
A Motor Service Set for Oil-Injected Screw Compressors
The official description ties the kit to the oil-injected screw range, and the rebuild note ties it to the GA VSD+ drive motors of the smaller frames. In that generation of machines the motor is built close to the element, and the service work on the motor end is planned as its own stop. The 2901200616 is the set the parts list shows for that work.
The number is also the line that parts desks record against the machine file. A plant that holds a GA VSD+ of the connector era finds the 2901200616 on the motor overhaul position of its parts book, and the same number travels through the rebuild note for the connector conversion.
Why a Kit Instead of Loose Parts
Eleven line items sit inside the 2901200616, from the bearing ball down to the wave spring, and several of them are needed in quantities of two or six. Sourcing those positions separately means eleven order lines with eleven chances for a mismatch.
The kit closes that gap. The contents are fixed at the factory, packed together, and checked in against one contents line at the bench. That is the practical difference between a kit number and a shelf of loose parts.
The GA VSD+ Machines Behind the Kit
The rebuild note that carries the 2901200616 names three motor ratings, 7 kW, 11 kW and 15 kW, and each rating has its own stator number. These are the drive motors of the GA VSD+ machines of the connector era.
The 7, 11 and 15 kW Drive Motors
The three ratings map onto the GA 7 VSD+, the GA 11 VSD+ and the GA 15 VSD+. The motor itself is not exchanged on an overhaul of this kind; the machine keeps its motor and the kit renews the parts inside it that wear.
The stator enters the picture only when the connector conversion is carried out, because the plastic connector build uses a new stator of the matching rating. A 7 kW machine takes stator 1625420387, an 11 kW machine takes 1625420386, and a 15 kW machine takes 1625420385.
The 3IN1 Connector and the 05/2014 Line
The 3IN1 connector, number 1625420820, was fitted in production until 05/2014. The official note states that this connector can no longer be delivered, and that the machine is rebuilt to the plastic connector instead.
That line in the production history is what fixes the machine group for the 2901200616. A GA VSD+ built before the cut carries the old connector, and its motor overhaul is planned together with the conversion; a machine after the cut carries the plastic connector from the factory and takes the overhaul kit on its own.
The Connector Rebuild Package
The official note lists the parts ordered for one conversion. The 2901200616 is the motor overhaul kit in that list, and the rest of the line covers the connector side of the work.
What the Official Note Lists
For the rebuild, the note orders the stator of the matching rating, the top cover 1625420403, the motor cable 1625427600, the connector kit 2901200621, the motor overhaul kit 2901200616, three nuts 0261109158 and two screws 0226 3139 25.
| Position | Number | Quantity |
| Stator 7 kW | 1625420387 | 1 |
| Stator 11 kW | 1625420386 | 1 |
| Stator 15 kW | 1625420385 | 1 |
| Top cover | 1625420403 | 1 |
| Motor cable | 1625427600 | 1 |
| Connector kit | 2901200621 | 1 |
| Motor overhaul kit | 2901200616 | 1 |
| Nut | 0261109158 | 3 |
| Screw | 0226 3139 25 | 2 |
Only one stator number applies per machine, chosen by the rating of the drive motor. The other lines are the same for the three ratings.
Where the 2901200616 Sits in the Work
The conversion changes the connector, and the overhaul renews the motor end, so the two jobs land in the same stop. Opening the motor once for both means the machine leaves the floor with a new connector line and a renewed bearing and sealing set in the same running hours.
That is why the note carries the 2901200616 inside the rebuild package rather than beside it. The kit is ordered with the conversion parts, and the work is booked as one motor job.
What the 2901200616 Kit Carries
The contents of the 2901200616 fall into three groups: the bearing and the spring that set the bearing position, the o-rings and the gasket that close the motor, and the washers and lock nuts that fasten it back together.
The Bearing and the Wave Spring
One bearing ball is the core of the kit, and the tariff code of the 2901200616, 84821090, is the code for ball bearings. The wave spring travels with it and holds the bearing position under load, which is why both are renewed together.
A bearing position that has run to its service hours is renewed rather than judged, because the cost of a motor job is in the opening of the machine and not in the parts. The kit puts both parts in the same box for that reason.
The O-Rings and the Gasket
The sealing group is the largest part of the 2901200616. It carries one o-ring 40X2, two o-rings of the standard line, two o-rings 153.5X1.6, two o-rings 67X3 and one o-ring 38X2, together with one gasket and one rebuild kit for the o-ring and bearing position.
Every one of these parts is renewed at an overhaul even when it looks serviceable. An o-ring that has taken a set in its groove loses its seal after refitting, and a motor that is opened twice for one leaking seal costs far more than the ring.
The Washers and Lock Nuts
One washer M50 and six lock nuts M8 complete the fastening side. The lock nuts are renewed because they are torque-limited items, and the washer seats the joint it is supplied for.
With all three groups in hand, the 2901200616 covers the motor end from the bearing position out to the last fastener, and the workshop does not stop the job for a missing small part.
When the Motor Is Overhauled
The decision to open a GA VSD+ motor is taken on running hours and on the readings of the machine, and the overhaul is booked into a planned stop.
Readings Before the Stop
Motor temperature at steady load, the current the machine draws, and vibration at the drive end are the readings that carry the decision. A bearing position approaching the end of its life shows in vibration first, and in temperature as the wear advances.
Taken across the service intervals, the readings tell a plant whether the 2901200616 belongs in the next planned stop or in the one after it.
Work Done with the Connector Rebuild
On a machine of the connector era, the overhaul is planned with the conversion. The motor is opened once, the plastic connector build is completed with the stator, the top cover, the motor cable and the connector kit, and the 2901200616 renews the bearing and sealing line while the motor is open.
On a machine that already carries the plastic connector, the same kit is used for the overhaul on its own, and the conversion lines drop out of the order.
Handling the Kit at the Bench
The 2901200616 weighs 230 g and measures 100 × 100 × 30 mm, so the logistics of the job are in the planning and not in the lifting. The discipline of the work sits in the condition of the small parts.
Clean Conditions for Sealing Parts
Each o-ring stays in its packaging until it is fitted, and the bearing stays wrapped until the shaft is ready to receive it. A sealing lip that takes grit at the bench carries that grit for the life of the motor.
The motor internals are cleaned before the new parts go in, and the old gasket material is removed completely before the new gasket is seated.
Recording the Job
The kit number and the date go into the machine file with the readings taken after the first run. On a converted machine, the connector numbers are recorded in the same entry, so the history of the motor shows both jobs in one line.
That record is what the next service planner reads, and it is the reason the 2901200616 is written down as a kit rather than as its eleven contents.

FAQ
What is the 2901200616 used for?
The 2901200616 is the motor overhaul kit for oil-injected screw compressors, named in the official rebuild note for the 7, 11 and 15 kW GA VSD+ drive motors. It renews the bearing position and the complete sealing line of the motor in one stop.
Which machines take the 2901200616?
The kit is placed with the GA 7 VSD+, the GA 11 VSD+ and the GA 15 VSD+ drive motors of the 3IN1 connector era, built until 05/2014. Machines of that group take the kit with the connector rebuild, and later machines take it for the overhaul on its own.
What is inside the 2901200616 kit?
The kit holds one bearing ball with its wave spring, the full o-ring group with the gasket and the rebuild kit for the o-ring and bearing position, one washer M50 and six lock nuts M8. The eleven line items are listed in the contents table above.
Does the overhaul require the stator and the connector kit?
Only on a machine that still carries the 3IN1 connector 1625420820. That connector is no longer delivered, and the conversion to the plastic connector adds the stator of the matching rating, the top cover, the motor cable, the connector kit 2901200621 and the fasteners to the order.
Why is the tariff code 84821090?
The tariff code of the 2901200616 is the code for ball bearings, which reflects the bearing ball at the centre of the kit. The code and the origin Belgium are the figures the item data records for customs purposes.
How is the 2901200616 ordered?
Send Seadweer the compressor model and serial number together with the kit number. The team confirms the motor rating of the machine, whether the connector rebuild applies, and the full parts line for the stop.

Ravi Menon –
We took the 2901200616 out of the stores for a GA 11 VSD+ that had run past its motor service hours, and the contents line matched the parts list one for one. The bearing, the o-rings and the lock nuts were checked in at the bench before the motor was opened, and nothing had to be ordered again in the middle of the job. The machine went back on the floor the same week, and the kit number is now written in the machine file against that overhaul date.
