Kramer 620 Parts Catalog – The Only OEM Source for Spare Part Numbers

If you are tearing down a Kramer 620 wheel loader and you need a seal kit, a water pump gasket, or the exact part number for a hydraulic hose, you do not want a reprint copy that blurs the illustration numbers. You want the factory document that the technician at Kramer-Werke GmbH used when he wrote the order list. This is that document: the Kramer 620 Parts Catalog, 194 pages, edition 2.1 from August 2000. It covers every major system on the machine – engine, fuel, cooling, hydrostatic drive, steering, electrical – and it lays out each assembly with the original German, English, and French labels. Aftermarket parts catalogs leave out the revision history and the exact supersession chain. This one gives you the full picture. Need the charge pressure line part number? Page 73 in the hydrostatic drive section. That level of detail is what keeps a loader in the field instead of waiting for the wrong o-ring to arrive.

Engine and Fuel System Coverage – What the Factory Lists

The manual opens with the engine section (Motor / Engine / Moteur) and moves straight into Fuel lines (Kraftstoffleitungen / Fuel lines / Conduites de carburant). You get exploded diagrams for the injection pump mounting, the fuel filter head, and the return line assembly. Every fastener, gasket, and banjo bolt gets a callout number that ties to the parts number reference list in Part B (pages 4–5 in the general information section). If you have a leaking fuel tank, the Fuel tank section (Kraftstoffbehälter / Fuel tank / Réservoir à carburant) shows the tank with its sender unit, filler neck, and mounting straps – all with genuine factory part numbers. Aftermarket catalogs often compress these into one generic tank drawing. Here, you see the actual hose routing for the return line. That matters when you are standing in the parts room with a dirty tank and a puddle of diesel.

Cooling System – Don’t Order the Wrong Radiator

Another common mistake: guessing the coolant pipe configuration on the Kramer 620. The Cooling section (Motorkühlung / Engine cooling / Refroidissement moteur) gives you a full breakdown of the radiator, fan shroud, expansion tank, and the coolant lines to the block. You will see the part number for the water pump gasket, the fan belt tensioner pulley, and the specific hose clamps (part number callout, not a generic size). The document also lists the cab heating (Fahrerhausheizung / Cab heating / Chauffage de la cabine) which ties into the cooling system. If you skip the cab heater matrix and order a standard radiator, you will lose the heater supply line connection. The factory diagram shows both circuits.

One thing I respect about this catalog: the Maintenance and sealing kits section (Wartungs- und Dichtsätze / Maintenance and sealing kits / Kits d’entretien et d’étanchéité) lists complete overhaul gasket sets with the exact number of o-rings and seals. That is the kind of detail that saves a Saturday afternoon. You do not open the kit and find you are short a banjo seal. The factory has already counted them for you.

7 Systems Covered – Beyond the Drivetrain

This Parts Catalog does not stop at the engine bay. It covers the hydrostatic drive (with the pump and motor exploded), the front axle (including steering knuckles), the rear axle (with brake parts), the steering valve, the operator seat (seat cushion and armrest part numbers), sheet-metal panels, wheels and rims, exhaust system, electrical system (switches, warning lights, harness connectors), cab, hydraulic system (pump, valve bank, cylinders), bucket, and pallet fork attachments. Every section uses the same tri-lingual layout. If you need a specific bolt for the hydrostatic pump mounting flange, you flip to the hydrostatic drive chapter and find the callout. The parts number reference list in Part B (page 3 of the document) gives you a cross-index by number. That is the way a serious shop works: start with the exploded view, get the number, verify the edition date (2.1 – August 2000), and order. No second-guessing.

Source Validity – Why OEM Documentation Matters

I have been burned by aftermarket parts manuals that show a generic filter and say “fits” – only to find the thread pitch is M20x1.5 instead of M22x1.5. This Kramer 620 Parts Catalog is a direct scan of the original Kramer document (ET 304 59, order number 0490030090). It carries the copyright notice from Kramer-Werke GmbH, printed in Germany. The edition history shows it went through six revisions from October 1995 to August 2000, meaning the part numbers have been updated for each production change. When you use an OEM catalog, you are seeing the same drawing the dealer parts counter uses. There is no translation guesswork because the German, English, and French columns sit side by side. If you want to understand the automotive industry standards for parts numbering, you can read the Automotive Industry Overview – but for practical ordering, you want the factory book. The Automotive Industry Overview is background; this catalog is the tool.

Who Should Buy This Manual – And Why One Copy Is Enough

If you own a Kramer 620 wheel loader and you do your own maintenance, or you run a small shop that services these machines, you need this catalog on the bench next to the laptop. The exploded views let you disassemble without losing track of fasteners. The part numbers let you order from any dealer without paying a markup. The 194-page count means you get every system – from the Engine down to the Labels and tools chapter (Schilder und Werkzeuge / Labels and tools). Beginners who have never ordered parts for a German-built machine will appreciate the tri-lingual labels; professionals will appreciate the edition history that tells them if they have the latest revision. Do not buy a generic photocopy that cuts off the margin numbers. This is the real thing.

Does this catalog include torque specifications for engine bolts?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. You will not find torque values here. For that you need the service manual.

How are the part numbers organized?

The document uses two parts: Part A (general information and system exploded views) and Part B (a numerical index of all part numbers). The index in Part B (page 3) cross-references each callout number to the illustration page and position. So if you find a number like 0490030090 in the fuel section, you can look it up in the index to verify the correct edition.

Is this catalog specific to the Kramer 620 model only?

Yes. The cover and header clearly indicate “Kramer 620” with the type number 304 59. It is not a multi-model book. Every part number is specific to the 620 wheel loader as built from the first edition (October 1995) through the final edition (August 2000). If you own a 620 with a serial number between 304 59 0001 and later, this applies.

Can I print and bind this PDF for shop use?

Yes. The file is a single 194-page PDF with no DRM. You can print the pages you need or keep a full set in a binder. Many shops do this for the engine and fuel sections. The OCR excerpt confirms the page numbering is sequential and legible.

Bottom line: if you are ordering parts for a Kramer 620 and you want to stop guessing which seal matches the hydraulic pump, grab the factory parts catalog. It is 194 pages of engine, fuel, cooling, and everything else that bolts onto that machine. Access the Factory Manual and put the right part numbers on your order sheet.
