What This Dynapac F121W Spare Parts List Covers

This is the complete illustrated spare parts list for the Dynapac F121W, F121W-4W, F121W-6W and F121W/D wheeled pavers built under serial number 634.163 and VB510TV screed serial 6140250. Every assembly on the machine is broken down into its component parts, with part numbers, descriptions, quantities, and exploded-view illustrations showing exactly how each piece fits together. If you maintain, repair, or rebuild one of these pavers, this is the reference that tells you which part to order and where it goes.

The catalog is organized into 15 numbered groups, from the main frame and rear axle through the hopper, conveyor, auger, screed arms, hydraulic system, electrics, and levelling equipment. Each group opens with a drawing, followed by itemized tables listing every part number, name, and quantity — including the fasteners, washers, seals, bearings, and wear items that get overlooked until they fail.

Grp. 01 – Main Frame

The structural backbone of the paver. This group covers the main frame, push roller beam, side screed arm lock, laying thickness indicator, dipstick, and the mounting hardware that ties the frame together. Exploded views show the frame compl., twist locks, cable guides, and cover plates, with every bolt, washer, and nut called out by part number.

Grp. 02 – Rear Axle

Everything behind the rear wheel drive: the planetary gear, adjustment motor for the drive axle, rear wheel assemblies, and the hydraulic motor that turns them. The planetary gear is broken down to individual gears, bearings, seals, and circlips. This is the group you need when a wheel drive leaks, a planetary fails, or you are replacing a rear tire and rim.

Grp. 03 – Steering, Front Wheel and Operator Desk

Three related assemblies grouped together. The steering section covers the steering column, wheel, track rods, rod ends, and the hydraulic steering cylinder. The front wheel group lists the non-driven front wheel components, including bearings, labyrinth washers, axles, and shackles. The operator desk section covers the moveable console, roller assembly, cover plates, and the gas struts and fasteners that hold it all together.

Grp. 04 – Side Screed Arms

The arms that carry the screed out to the sides of the paver. This group covers the left and right side screed arms, the hydraulic cylinders that raise and lower them, the sliding plates, roller heads, and the pins, bushings, and fasteners that take the wear. If your screed arms are loose or the cylinders are leaking, this is where you find the replacement parts.

Grp. 05 – Conveyor

The conveyor system that moves material from the hopper to the auger. Covered here: the conveyor turn, conveyor plates, conveyor gear with dipstick, drive for the conveyor gear, limit switch, chain guide, and the conveyor drive itself. Exploded views show the chain wheels, bearings, shafts, and the hydraulic motor that powers the conveyor.

Grp. 06 – Hopper

The hopper assembly, including the hopper compl., cover flaps (left and right), and dump plate. The group shows the flat steel, rubber plates, supports, and mounting hardware that make up the hopper sides and the folding flaps that guide material into the conveyor.

Grp. 07 – Engine, Drive and Split Gear Box

The powertrain. The engine group lists the D900-07072 engine assembly and its service parts, along with the water-oil-air cooler, oil drain, air guide plates, silencer, tank attachment, fuel equipment, and air cleaner mounting. The drive group covers the engine frame, engine mounts, cooler hoses, and the hardware that holds the engine in place. The split gear box group is the most detailed: a full exploded view of the split gear with its housing, flanges, spur wheels, shafts, bearings, seals, and shims, plus the tandem pump, individual pumps, and the valve block that distributes hydraulic power.

Grp. 08 – Hydraulic

One of the largest groups in the catalog. It covers the complete hydraulic system: valve views, steering, auger, vibration, tamper, levelling, hydraulic oil tank, screed, manifold, work hydraulic, conveyor, drive control unit, and the master view cylinder. Hydraulic cylinders are listed with their seal kits, hinge bearings, hoses, and fittings. The group includes schematic diagrams as well as exploded views, so you can trace a circuit or find the exact cylinder and seal kit for a repair.

Grp. 09 – Electric

The electrical system, split into sub-groups: terminal holder, lighting, drive control unit, levelling, hopper, tamper, vibration, screed functions, differential lock, conveyor and auger, engine, electronic engine governor, limit switches, power supply for additional functions, electric mounting parts, and the operator desk. Each sub-group lists the switches, relays, fuses, plugs, sockets, cables, sensors, and control modules with their part numbers. This is where you find the replacement for a failed toggle switch, a blown fuse, a sensor, or a dash indicator.

Grp. 10 – Operator Platform

The platform structure, guard plates, footwell, side panelling, step, mounting parts, engine hood, tank hood, and tool box. The group covers the sheet-metal panels, insulating boards, latches, hinges, gas struts, and the hardware that keeps the operator station and engine enclosure complete.

Grp. 11 – Auger

The auger assembly and its extensions. Starting with the 380 mm auger, the group covers the auger drive, auger gear, scraper plate, sensor holder, grease pipelines, limit switch potentiometer, and the full range of working-width extensions from 4.25 m up to 8.10 m. Each extension is broken down to its auger shaft, wear part kit, and mounting hardware. This is the group to use when you are rebuilding worn auger flights or changing the working width.

Grp. 12 – Tools, Signs and Decals

The accessories, tool kit, and the complete decal set for the machine. Includes the warning signs, information plates, noise-level decals, and the Dynapac branding decals, along with the hand tools and grease gun that ship with the paver.

Grp. 13 – Option, Special Equipment

Optional equipment fitted to some machines: remote control, weather protection roof, diesel spray equipment, adjustment spindle mechanism, and back-up alarm. Each option is fully broken down with its own part numbers and illustrations.

Grp. 14 – Wear Part and Maintenance Kits

Pre-packaged kits for scheduled service and common wear items: the Deutz 6-cylinder inspection kit, 500-hour service kit, conveyor plate kit, conveyor drive kit, roof profile kit, conveyor chain kit, auger wear part kit, and the 500 h Plus TIER 3 service kit. These kits bundle the filters, seals, wear plates, and hardware you need for a specific job, so you are not ordering each part individually.

Grp. 15 – Levelling

The grade and slope control equipment: mechanical parts for the grade control assembly, levelling bar, support for grade control, slope control, and the MOBA grade control system. This group covers the sensors, arms, holders, clamps, and spindles that keep the screed at the correct grade and slope.

How the Catalog Is Organized

Every group follows the same pattern: an exploded-view drawing on one page, with numbered callouts pointing to each component, followed by a table that matches each number to a part number, name, quantity, and any serial-number or model notes. The drawings are clear line art, and the tables are laid out so you can read across from the illustration to the part number without guesswork. Where a part is used more than once, the quantity column tells you how many to order. Where a part varies by serial number or model variant, the notes column flags it.

The catalog also includes cross-references: for example, the hydraulic cylinder pages point to the seal kit pages, and the hydraulic group references the individual cylinder drawings. This saves you from ordering the wrong seal kit or missing a related component.

Why This Parts List Belongs in Your Workshop

Ordering the wrong part is expensive and slow. A parts list that matches your exact machine — serial number 634.163, screed serial 6140250 — removes the guesswork. You look up the assembly, find the item number on the drawing, read the part number from the table, and order with confidence. The catalog covers every system on the paver, from the main frame down to the washers and cotter pins, so you are not stuck when a small fastener or a seal fails.

For a workshop that services Dynapac pavers, this is the reference that keeps jobs moving. It supports everything from a routine filter change to a full planetary gear rebuild, from replacing a blown fuse to re-sealing a hydraulic cylinder. The exploded views show how parts fit together, which is invaluable when a component comes apart on the bench and you need to know the order of the shims, circlips, and bearings.

The PDF is delivered instantly after payment — no shipping, no waiting for a disc. It opens on any device, and you can print the pages you need for the workshop floor. Keep it on the laptop in the service truck, or print the hydraulic and engine sections for the bench. Either way, you have the full catalog in your hands the moment you need it.
