Volvo BM 4600 1984 Parts Catalog

I have spent 28 years turning wrenches in San Antonio. One thing that grinds my gears is trying to track down the right part number for a Volvo BM 4600 1984 Parts Catalog from 1984. Aftermarket catalogs are a guessing game. You end up with wrong seals, mismatched hoses, and a machine that sits dead. That is why I keep the factory print on the shelf – 270 pages of exploded views and part numbers. No reprints. No third-party guesses.

What the 270 Pages Give You

Every page in this catalog is an original factory scan from 1984. The book is organized by group numbers: Group 51 covers the double brake pedal assembly, Group 61 tackles the steering system components and hoses. Each figure shows an exploded view with callouts that match a part number, quantity, and description in both Swedish and English. If you need to order a replacement roller, footplate, or hydraulic pump, the part number is right there – no cross-referencing with a generic chart. Page 3 shows the double brake pedal breakdown with part numbers like 4051802-5 for the footplate and 951980-8 for the axle. Page 4 lists the steering system with 35 individual components, including the hydraulic pump (931838-0) and hoses like 931644-7. That level of detail saves you a phone call to the dealer and a week of waiting for the wrong part.

Never guess on hydraulic hose part numbers.

Double Brake Pedals: Group 51 Breakdown

The double brake pedal assembly is a common wear item on loaders. This catalog walks you through each piece: footplate, axle, spring pin, elastic washer, washer, and roller. Part numbers are listed with quantities – for example, item 2 calls for two footplates (4051802-5). The manual also includes notes on fasteners and washers. When you are rebuilding the brake pedal linkage, having the OEM part numbers means you can order directly from Volvo BM stock without playing match-the-bolt at the hardware store. Safety note: double brake pedals on heavy equipment must be torqued to factory spec – the catalog does not list torque values, but it gives you the exact part numbers for each component so you can source the correct fasteners and then look up the torque in the service manual. Don’t be the guy who uses a generic bolt because the part number was missing.

Steering System Components and Hoses (Group 61)

Steering system failures are dangerous. Group 61 covers the hydraulic pump, valves, cylinders, hoses, and fittings. The exploded diagram on page 4 shows the master cylinder, manifold, and 25 different hose part numbers. Each hose is listed with its specific length and bend – that matters when you are replacing a high-pressure line on a 4600. Using a generic hose that is too short or the wrong end fitting will blow out under pressure. I have seen it happen. The catalog also includes O-rings and couplings (part numbers 931780-0 and 403190-5). For repairs, you need the exact hose assembly – this catalog gives you that. Pair it with the service manual for assembly procedures.

Three Reasons to Use the Factory Parts Catalog

First, every part number is verified by Volvo BM engineers. Aftermarket catalogs often transpose numbers or skip superseded parts. Second, the catalog is bilingual – Swedish and English – so if you are working on a machine that was originally sold in Europe, the Swedish notes clarify which fasteners are used. Third, the 270 pages cover the entire machine: drivetrain, hydraulics, brakes, steering, and body. You are not hunting for a separate supplement. This catalog is the complete parts reference for the 1984 4600. If you need a similar manual for a different model, check the Volvo BM 125C 1988 Parts Catalog – OEM Factory Specs or the Volvo BM Michigan 125C 1988 Parts Catalog – Factory OEM Parts Manual. For transmission basics, the Volvo BM Michigan FH Training Manual – Transmission Basics is worth having on the same shelf.

Workshop Tips: Reading the Parts Catalog

When you open this catalog, start with the group index. Each group is a major system. Look up the figure number for your part, then cross-reference the callout number with the table. The part number is in the column “Art.nr” – that is your order code. Always verify the quantity column – some assemblies require two of the same part. I keep a highlighter on the bench and mark the parts I need before I call the supplier. One more tip: the catalog uses Swedish notes like “Stötdämpning” for shock absorption – don’t ignore those. They indicate special washers or bushings that are not interchangeable. Safety warning: never substitute parts from a different group without checking the dimensional fits. The factory catalog is your insurance against field modifications that fail.

Frequently Asked Questions

Is this manual in English?

Yes, it is bilingual Swedish/English.

Does it include wiring diagrams?

No. This is a parts catalog – it contains exploded views and part numbers for mechanical and hydraulic components. Wiring diagram data is in the separate service manual.

What years does this catalog cover?

This is the 1984 edition specifically for the Volvo BM 4600 model. However, part numbers often carry across production years within the same series. If your machine is a 1983 or 1985 4600, many components will be identical, but always verify with the part number – the catalog includes all parts used up to the 1984 production date. For later models, the factory released supplements that are not in this print.

Can I use this catalog for the Volvo BM 4600 loader with a different attachment?

Yes, the catalog covers the base machine; attachment parts for buckets, forks, or grapples are listed in separate attachment catalogs. This manual gives the main chassis and drivetrain parts.
