Fiatallis DD Parts Catalog – OEM Factory Specs for the DD Motor Grader

If you’ve ever ordered a part for a Fiatallis DD motor grader based on a sketchy aftermarket number and got a box full of wrong metal, you know the pain. The Fiatallis DD Parts Catalog is the only document that gives you the exact factory part numbers, exploded assembly drawings, and the safety warnings that keep you from getting crushed. I’ve been turning wrenches for 28 years, and I can tell you: using a genuine OEM parts catalog is faster than cross-referencing three different supplier catalogs. This one has 307 pages of nothing but parts data.

Fiatallis DD Parts Catalog: What You Get

This is not a reprint or a scanned copy of a copy. It’s the original factory PDF as released by Fiatallis. The cover page says “FIATALLIS DD MOTOR GRADER PARTS CATALOG” and it covers serial numbers 1 thru 4500 and 73L04501 up. That’s the range you need to confirm before buying. Page 2 has the “AVOID ACCIDENTS” warning that every mechanic should read before touching the machine. It states: “Never attempt to clean, oil or adjust a machine while it is in motion.” That alone could save your life.

Engine D-262 and Fuel Injection System Parts

The catalog breaks down the engine into sub-assemblies. Under “Engine D-262” you’ll find the cylinder block, cylinder head, crankshaft, pistons, and the fuel injection system. Both Bosch PSB Pump and Roosa Master fuel injection pumps are listed. Each component has an illustration with callouts and a corresponding part number. If you need a injection nozzle for a DD grader, you can look up the exact Fiatallis part number in minutes.

Hydraulic System and Steering Components

Hydraulic system sections cover the pump, control valves, cylinders, and hoses. Power steering components are separated out. The manual shows the exploded view of the steering gear and the wheel lean mechanism. When a seal blows on a Saturday, you don’t want to guess which kit to order. This catalog gives you the kit number.

Tandems, Brakes, and Moldboard Assembly

The tandem drive housing, brakes, circle, drawbar, and scarifier are all covered. The moldboard assembly diagrams include blade groups, linkages, and hydraulic cylinders. For a machine that spends its life in dirt and mud, having the correct wear part numbers saves a return trip to the parts counter.

307 Pages of Part Numbers – No Aftermarket Guesswork

Every page in this catalog is a factory scan – no aftermarket redrawing, no lost detail. Page numbers run from 1 to 307, and each one carries the original Fiatallis copyright. If you’ve ever tried to use a third-party parts list from some online forum and ended up with a bolt that’s two threads too short or a seal that’s the wrong durometer, you understand why factory documentation matters. The exploded views are crisp, the callout lines are clear, and the part number fonts match the ones on the original Fiatallis packaging. That might sound like a small thing, but when you’re standing in front of a machine with a broken hydraulic line, having the exact number saves you a trip back for another hose. I’ve been there. Stick with the factory catalog.

Safety Warnings from the Factory

Page 2 also includes a warning about hydraulically or cable-controlled equipment: “be certain the equipment is lowered to the ground before servicing.” And if you need to raise it, “suitably supported by means other than the hydraulic lift cylinders.” That’s the kind of specific safety language you only get from the OEM. Aftermarket catalogs don’t print this.

FAQ – Common Questions About This Parts Catalog

Does this catalog include torque specs?

No, this is a parts catalog only.

Can I use this to rebuild the engine?

That depends. If you need part numbers for pistons, rings, bearings, yes. But if you need torque sequences and clearances, you need the engine service manual. This catalog gives you the exploded view so you can see how everything goes together, but it won’t tell you the tightening order or oil clearance specs. I’ve seen guys try to rebuild an engine with just a parts catalog and then wonder why the head gasket blew. Don’t be that guy. Get both the parts catalog and the service manual for the full picture.

Is this the official Fiatallis manual?

Yes, it’s the original factory print, not a reprint or aftermarket copy. The copyright notice on page 2 confirms it’s copyrighted by Fiatallis.

What years and serial numbers does it cover?

This catalog covers the DD Motor Grader with serial numbers from 1 thru 4500 and 73L04501 up. If your machine is newer, check the serial number against the range.
