Description

Atlas Copco Boomer L2 D Spare Parts Catalogue — Document 8991 8998 00

The Atlas Copco Boomer L2 D Spare Parts Catalogue (publication number 8991 8998 00) is the complete component identification and ordering reference for the Boomer L2 D twin-boom face drilling rig. It is a parts catalogue rather than a repair manual: it tells you exactly which part number goes on which machine, in which position, and on which page of the catalogue that position is illustrated. Every assembly is shown as an exploded view with numbered callouts, and those numbers are tied to tables that give the Atlas Copco part number, the quantity, the Swedish and English description, and the drawing page. This is the document you use when you already know what failed and need the correct replacement, and it is equally the document you use to build a spares list, a rebuild kit, or a preventive-maintenance parts schedule for a rig in the field.

• 12. Cross Reference List — numeric cross-reference of every part number to its reference number and catalogue page

Taken together, the twelve chapters cover the entire machine: the hydraulics that drive the booms and rock drills, the carrier and driveline underneath, the two BUT 35M booms and their rotation units, the COP rock drills and MSQ hydraulic motors, the BMH feed beam assemblies, the electrical distribution and lighting system, the onboard compressor and water flushing circuits, the cab and platform, the cable reel, and — most useful of all for daily work — a consolidated hose list and a cross-reference index that lets you start from a part number and find where it lives. Every part is presented in both English and Swedish, so a workshop working in either language can order without translation errors.

What the Exploded Views Give You

Each assembly in the Boomer L2 D parts catalogue is drawn as a numbered exploded view. The numbers on the drawing match the reference numbers in the accompanying table, which lists the Atlas Copco part number, the quantity required, the description in English and Swedish, and, where the sub-assembly is broken down further, a pointer to the page where that detail appears. Seal kits, O-rings, back-up rings, bearings and shims are called out in the same way as major castings, so you can order a single O-ring or a complete cylinder seal kit from the same page.

Hydraulic Schematics and Electrical Documentation

The catalogue reproduces the machine’s hydraulic schematics with component reference numbers keyed to the parts tables, covering circuits such as the brake and steering system and the boom positioning system. The electrical section documents the D75/95*2 IEC 400-690Y/D system through its cabinet layout, junction boxes, apparatus panel and cable schedules. Together with the boom and feed diagrams, this makes the catalogue usable not only for ordering but for tracing which component sits in which circuit before you order it.

Component Manufacturers Referenced

Several assemblies in the catalogue are built from components that carry their own manufacturer names, and the parts tables preserve them. This is useful when you are cross-shopping a replacement outside the Atlas Copco network. Alongside the Atlas Copco part numbers you will find references to:

• Deutz TCD2013L04 2V diesel engine (motor unit)
• COP 1838HD, COP 1838ME and COP 1638-2560 rock drills and their overhaul kits
• MSQ 80 SH, MSQ 100 SH, MSQ 160 SH and MSQ 250 SH hydraulic motors
• Michelin XZM 14.00R24 tyres and 10.00 X 24 rims
• Ansul fire suppression system components
• Blue Aero air filter (3222 1881 30)
• Suco pressure switches, Wika pressure gauges, Sterling valves and ECL lubrication pump

How to Use It for Ordering

Atlas Copco’s own instruction on the second page of the catalogue is worth repeating: when ordering spare parts, state the part number — not the reference number — and the quantity. The reference number is only an index into the exploded view; the part number is what the dealer needs. The cross-reference chapter at the back of the manual lets you do the reverse lookup, so a part number found on a machine label or an old invoice can be traced back to the drawing and the surrounding components. Because the same part number can appear in more than one assembly, the cross-reference also tells you every page where that number is used.

IMAGES PREVIEW

Bilingual Advantage

Atlas Copco Rock Drills AB published this catalogue in English and Swedish side by side. Every table row carries both the English description and the Swedish benämning, and the cover pages and chapter headings are given in both languages. For workshops in Scandinavia, or for anyone buying a used Boomer L2 D that came out of a Swedish or Nordic fleet, this removes the usual translation step: the Swedish name printed on a machine plate can be matched directly to the entry in the catalogue, and the English equivalent read off the same line.

Who This Catalogue Is For

This is a working document for the people who keep a Boomer L2 D running: workshop technicians building a parts order, service managers pricing a rebuild, procurement staff identifying a replacement after a failure, and owners of a used rig who need to know what is actually on the machine before they buy. It is not a repair manual — it will not walk you through stripping a boom cylinder or setting rock drill impact pressure — but it is the document you need open on the bench next to whatever repair guide you are using, because it gathers every part number, seal kit, hose length and exploded view for the L2 D into a single reference.

Order the Right Component the First Time

With the Atlas Copco Boomer L2 D Spare Parts Catalogue 8991 8998 00 on hand you can identify and order the correct component the first time, whether that is a single O-ring for a leaking boom cylinder, a complete seal kit for the COP 1838HD rock drill, a replacement hydraulic motor, a BMH feed hose, or a full set of hydraulic hoses for a machine coming due for overhaul. Correct part numbers matter: a wrong seal or a mismatched hose on a 210-bar boom circuit is a comeback, a leak, or worse. The catalogue is delivered as an instant PDF download — no shipping, no waiting, no print copy to lose in the workshop. Open it on a laptop, tablet or phone, print the pages you need for the job, and keep the rest of the 1,012-page reference on file for the next repair.
