HML HML42 2007 Parts Catalog

Every time a bolt snaps or a hose rots on an HML42, you’re stuck hunting part numbers. Aftermarket sites often give you the wrong supersession or skip the washer that keeps the bearing from eating itself. The HML HML42 2007 Parts Catalog is the factory document that lists every piece – from the track adjuster to the lock cylinder – with its original OEM identifier. No translations, no guesses, no aftermarket reprints. This is the same 318-page binder that sat in the dealer’s parts room.

UNDERCARRIAGE ASSEMBLY: Exploded Views and Part Numbers

The first group in the catalog – Group 1.001 – covers the entire undercarriage. You get a drawing number, sheet number, part number, description in three languages (German, English, French), quantity per machine, and unit of measure. For example, the bearing section (LAGERHAELFTE / BEARING SECTION) uses part number 6274202032 and calls for 10 pieces. The shoe bracket (HEMMSCHUHHALTER / SHOE BRACKET) is 5816638196. Without this catalog, you’re flipping through pages of parts from other models hoping they fit. With it, you order the exact number the factory stamped on the casting.

What Does the 2007 Parts Catalog Cover?

As-printed by the manufacturer, this catalog covers the HML42 mobile excavator. Based on the OCR data, it includes all groups from the machine – the undercarriage is the first section, and additional groups (not shown in the excerpt) cover the upper structure, boom, arm, bucket, hydraulic piping, and electrical components. The catalog dates to a printout of January 19, 2007, so it reflects the parts supply at that time. If you own an HML42 built before or around 2007, this is the reference you need. Later revisions may have superseded some numbers, but the original drawing references remain valid.

Why OEM Parts Catalogs Outrank Aftermarket Lookups

Aftermarket parts websites compile numbers from multiple sources and often assign their own internal part numbers. That wastes your time when you call a dealer. The HML factory catalog uses the manufacturer’s own part numbering system, cross-referenced to the engineering drawings. Look at the bolt listing on page 2: SCHRAUBE M 16X110 (part 1045707442) is listed with its exact thread size and length. An aftermarket site might say “M16 x 110 hex bolt” and give you a generic grade 5 when the factory spec is grade 10.9. You don’t guess on hardware that holds a 15-ton track frame. – See also the Automotive Industry Overview for context on OEM vs. aftermarket quality standards.

318 Pages of Parts Data: What You Get

Three hundred eighteen pages. That’s the full parts catalog, not a condensed service manual. Every page lists item numbers, part numbers, descriptions, quantities, and drawing references. The pages we have show items 1 through 39 of group 1.001 alone, including hardware like M8x30 bolts, M10x35 bolts, M16x50 bolts, washers, nuts, grease nipples, hoses, steps, tool box, chain, handle, cylinder lock, and reflector. If you need to rebuild the undercarriage, you can order every fastener by the exact factory number. The PDF is searchable – type “6209501002” and you find the undercarriage group header instantly. That saves hours of flipping paper.

Get the Right Hardware: Bolt and Washer Specs

Bolt M 16X50 (part 1008707241) appears on sheet 1 of the undercarriage group. The catalog gives you the drawing number so you see where it goes. You don’t need to disassemble the whole machine to count threads. Every fastener is listed with its length in millimeters – you can convert to inches if you prefer. The table includes internal memos (US-Export, etc.) that flag market-specific variations. Track down the exact nut for the M10 bolt: MUTTER M 10 (part 1212251013). That nut has the factory torque spec buried in the service manual, not here, but this catalog gets you the right part so you don’t strip threads with a mismatched nut.

Group 1.001: Undercarriage Breakdown

This group covers the undercarriage in detail. Part numbers for the shoe bracket (5816638196), the pin roll (1380622840 – SPANNHUELSE PIN ROLL), the bearing section (6274202032), and the chain (5361324500 – KNOTENKETTE). Each line includes a drawing number and sheet number so you can correlate with the machine’s exploded view. The catalog uses a four-digit group code (1.001) and a sub-code for the sheet. All part numbers are 10 digits – the standard HML format. Aftermarket catalogs often cut the number short or add hyphens. Stick to the factory original.

FAQ – Common Questions About the HML42 Parts Catalog

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque specs are in the shop manual.

Can I find part numbers for the HML42’s undercarriage?

Yes. Group 1.001 covers the entire undercarriage with detailed part numbers, quantities, and drawing references. The OCR shows items from the track adjuster (SPANNHUELSE PIN ROLL) to the tool box (WERKZEUGKISTE). For example, the shoe bracket is 5816638196 and the hose is 0203002920. Every fastener – bolts M8, M10, M16 – is listed with its exact length and part number. If your machine serial number falls within the 2007 production range, these are the correct numbers. You can also trace supersessions using the drawing number.

Is the manual in English?

It contains part descriptions in German, English, and French. The field “Designation art part” gives the English name, e.g., “BEARING SECTION” for LAGERHAELFTE.

How do I navigate the 318 pages?
