Atlas Copco 2906045200 ZR400-425 16000H Maintenance Kit

Descripción

El 2906045200 is the Atlas Copco 16000H maintenance kit recorded for the ZR400-425 oil-free screw compressors, issued under the item number shown beside the tables below, the parts scope for the 16000-hour service point of that frame. It reaches the workshop as one packed case carrying nineteen recorded lines — the longest contents list of the 16000H kits in this family — and it gathers the valve-side, drainage-side, filtration-side and sealing-side wear parts of the stop into a single order.

What sets the 2906045200 apart from the sister kits of this service mark is how deep the structure goes. Inside the case sits the inlet valve kit under its own part number, and inside that inlet valve kit a second small kit is packed again: the bearing block kit of the ZR300-425 inlet valve. A kit inside a kit inside the kit is the honest description of this parts scope, and it is also the argument for ordering it as one case instead of assembling loose lines.

This page follows the 2906045200 case from the recorded contents outward: the nineteen lines as they are printed, the inlet valve kit and its bearing hardware, the two drain valve kits, the filter with its newest-version record, the muffler pair, and the figures a planner needs before the shutdown. Every figure below is drawn from the official part data, so the tables can be used directly at the bench and in the machine file.

Inside the 2906045200 Case: Nineteen Recorded Lines

The contents recorded on the official part page for the 2906045200 show the scope of the stop in nineteen lines, each with its quantity:

The nineteen lines above are printed exactly as the official page of the 2906045200 records them, and several of their features matter at receiving. Two separate lines carry the designation FILTER ELEMENT, and the drainage side is printed twice as well — a DRAIN VALVE KIT line and a DRAIN VLV KIT line, each with quantity 1.

Three lines are kits with identities of their own: the inlet valve kit, the nested ZR300-425 4000H MAINT KIT and the +4++ CHECK VALVE KIT+. The remaining hardware covers the muffler pair, the Silencer, the VALVE and the sealing washers and O-rings of every position the stop opens.

For the planner, the nineteen lines of the 2906045200 are the receiving checklist in printed form, and the case label carries the kit number 2906045200 for that count. Each line is verified against the packing list before the machine comes off load, and the three kit lines are opened at the bench first, because the deepest contents of a kit are the ones a rushed count misses.

The Inlet Valve Kit: 2906044400

The KIT VALVE INLET line of the 2906045200 is supplied under its own number, 2906044400, recorded as the inlet valve kit for oil-free compressors. It is the heaviest mechanical assembly of the case — 4.5 kg in a 450 × 310 × 155 mm frame — and its own contents page runs to twenty-four lines, which makes it a service scope in its own right rather than a bag of parts.

Much of that list reads like a bearing overhaul written out in full: one BEARING, one ROLLER BEARING, one STUD with two NUT M12 units, one CIRCLIP, two BUSH units and one SPRING COMPRESSION.

Around the rotating hardware sit the sealing positions of the inlet valve.

They cover three O-RING designations including O-RING 16X2, four WASHER lines, two MEMBRANE lines, one DIAPHRAGM, one GASKET, two SEAL units and four SEAL WASHER DOWTY 1/4 units — the full set of consumables the position consumes when it is opened.

Two lines of the 2906044400 are kits again, and this is where the structure of the 2906045200 reaches its deepest point. The ZR300-425 INLET BRG BLOCK KIT renews the bearing block as one pre-assembled scope, and the KIT VALVE INLET ZR300-425 covers the valve itself for the same frame range. At the bench, the twenty-four lines are counted against the list before the valve housing is opened, because a bearing kit missing one of its small parts is a fault found at restart, not at the bench.

Two Drain Valve Kits in One Case

The drainage side of the 2906045200 is printed on the contents list twice, under two designations: DRAIN VALVE KIT and DRAIN VLV KIT, each with quantity 1. Both lines are carried exactly as recorded, and the case therefore renews the drain positions of the machine through two separate kit scopes rather than one combined line.

The DRAIN VLV KIT travels inside the 2906045200 under its own number, 2906031400, recorded for oil-free compressors. It is the lightest item of the case — 20 g in a 70 × 50 × 30 mm frame — and its contents page lists five lines: one MEMBRANE, one O-RING 36.2X3, one INSERT, one O-RING and one SEAL WASHER DOWTY 1/4.

Every one of those five parts is a wear item at the drain position, which is why the kit renews them together instead of leaving any of them measured and reused.

The drainage scope is also the part of the stop that is easiest to underestimate. Drain valves sit in the wettest corner of the oil-free package, and a membrane or an O-ring that survives one service interval rarely survives the next. With both drain kits inside the 2906045200, the condensate side of the machine is renewed at the same stop as the compression side, and no second order has to chase it later.

Filters and the Newest Version Chain

The filtration side of the 2906045200 is printed on three lines: two separate FILTER ELEMENT lines and one OIL FILTER EL line with quantity 2, so two oil filter elements travel beside the air-side elements. The oil-side pair and the element lines are consumed together at the 4000H and 16000H intervals, and the quantities in the 2906045200 are set so each filter position of the frame is renewed once per stop.

The air filter travels in the 2906045200 under its own number, 1630040699 — Germany as country of origin, 84213925 as customs tariff code, a 360 × 370 × 360 mm frame and a weight of 5.04 kg. The supplier record carries a note that matters for procurement: this product is the newest version of part number 1621574299. The earlier number is therefore superseded in the current parts documentation, and any parts printout that still shows 1621574299 resolves to the unit packed in this case.

That version chain is worth keeping in the machine file beside the 2906045200. Fleets that were built years apart can carry different filter generations in their paper records, and the newest-version note is what aligns the ordering number with the part that actually fits. The serial-based parts list remains the deciding record, and the parts desk confirms it before the order is processed.

Mufflers, Valves and Sealing Hardware

The MUFFLER line of the 2906045200 kit carries quantity 2, and both units are supplied under the number 1830020479 — the same muffler reference recorded across the 16000H kits of the ZR oil-free frames. Each carries Germany as origin, 84879090 as customs tariff code, a 200 × 90 × 90 mm frame and a weight of 715 gr, and the pair is renewed where the stop opens the muffler positions of the machine.

The remaining lines of the 2906045200 close the pneumatic and sealing scope. The +4++ CHECK VALVE KIT+ and the VALVE line renew their valve positions, the Silencer and the WASHER CHANNEL complete the gas-path hardware, and the sealing set — SEAL WASHER M32, one SEAL WASHER DOWTY 1/4, two SEAL WASHER DOWTY 1/2+ units, two O-RING units, one O-RING 7.3X2.4, one SET RUBBERS and one MEMBRANE — is consumed at every position the 2906045200 opens, so nothing from the old build returns to service by habit.

Dimensiones y peso

The figures set the handling plan. At 32.8 kg in a 120 × 80 × 90 cm frame, the 2906045200 moves on a pallet or a trolley and is positioned beside the machine before the shutdown, so the nineteen lines can be checked in without re-handling. Package details for the current build are confirmed with the quotation.

Planning the 16000H Stop on the ZR400-425

El 2906045200 is recorded for the ZR400-425 frames, and the 16000-hour mark is where their parts list calls for the scope gathered in this case. Build variants still differ within the fleet, and the parts list for each serial is the record that names the kit for the unit — the reference the parts desk confirms before any order for the 2906045200 is placed.

On the bench, the work runs from the deep end outward. The inlet valve kit is opened first and its twenty-four lines counted, with the bearing block kit and the valve kit it contains kept together as one work scope; the two drain kits follow at the condensate side; the filter positions take the element lines, the oil filter pair and the air filter under 1630040699; and the muffler pair, the check valve kit, the valve and the Silencer close the gas-path scope.

The sealing hardware is consumed at every position, so each station draws from the same case rather than from parts kept loose around the workshop.

After assembly, the machine served by the 2906045200 runs under observation before it returns to load, with the readings filed beside the 2906045200 and the service date. Plants that operate several ZR frames keep that record per unit, which turns the next 16000-hour stop into one confirmed message to the parts desk instead of a fresh investigation.
