Dieci Agri Star 37.8 2008 Parts Catalog – OEM Spare Parts Manual

You’re on a job and the lift arm seal blows. Your parts runner comes back with a box that says “fits Dieci Agri Star 37.8” but the bolt holes are 2 mm off. Now the machine is down another hour while you figure out the real part number. That’s exactly why this catalog exists. Dieci Agri Star 37.8 2008 Parts Catalog is the original factory document – 231 pages of part numbers, exploded group drawings, and revision codes that match what came off the assembly line in 2008. No translations, no aftermarket guesses. Just the data Dieci’s own service department uses when you call their hotline in Montecchio Emilia.

Parts Group Breakdown: How the Catalog Is Organized

Open to page 3 and you see the note: the catalog is divided into groups. Each group contains parts tables with exploded drawings. Those drawings include optional accessories not mounted on base machines – you have to check with the assistance office before ordering an optional. That’s a detail most aftermarket books leave out, and it’s the kind of thing that stops you from buying a hydraulic pump you don’t need. Group structure follows the same logic as the service manual – engine group, transmission group, hydraulics, steering, cab, electrical. Every part inside a group has a reference number tied to the Dieci spare parts system. If you’re rebuilding a Agri Star 37.8 from scratch, you work through these groups in order.

Why Aftermarket Parts Catalogs Fail on Dieci Machines

Third-party catalogs renumber parts. They drop the revision suffix. They replace “AXL0065” with a generic code that doesn’t match the Dieci computer. Then you get a seal kit with the wrong durometer or a bolt that’s 0.5 mm shorter. The Dieci OEM catalog uses the exact factory codes from the 2008 release – same codes stamped on the part itself. You match the code on the worn piece to the drawing in this book, and you order using that code. No cross-referencing. No returns. That’s the difference between a 20-minute parts lookup and a two-hour headache.

The Dieci XRM 732 Parts Catalog – OEM Spare Parts Manual 215 Pages covers a different chassis but uses the same group logic.

Ordering Optional Accessories: Page 3 Warning

Page 3 has a block of text in four languages that says: the drawings may show optional items not installed on base or special machines. If you want to order an optional, always ask the assistance office whether your specific machine has that provision. I’ve seen guys buy a third valve spool for an Agri Star 37.8 that didn’t have the pilot line drilled – because they saw it in the exploded view and assumed it was standard. That’s a $400 mistake. The catalog is honest about what’s optional; you just have to read the footnote. Dieci’s own service people follow that rule. So should you.

Using This Catalog with a Service Manual

Fastener torque specs and hydraulic pressures are not in this catalog – that’s in the service manual. What you get here is the part number for the O-ring, the filter, the electronic control unit, the steering cylinder seal kit. To rebuild that cylinder, you need the service manual for the disassembly procedure and this catalog for the replacement parts. The part numbers are grouped by assembly – for example, the boom group drawing shows every pin, bushing, and snap ring with individual item numbers. Write the item number, match it to the parts table, and order. If you’re dealing with electrical failures, the catalog also lists wiring harness part numbers – but the wire colors and connector pinouts are in the electrical schematics manual. Two books, one system. Never order a part number from a third-party site when the original factory drawing is 231 pages deep in front of you. For additional component knowledge, read about common failures on Starter Motors and check the Automotive Industry Overview for telehandler developments – but the part numbers stay with Dieci.

231 Pages of Factory-Coded Components

Dieci printed this catalog in October 2008 – Release_10_2008. Every page number corresponds to a section. The front matter includes the CE declaration and the monotony of legal disclaimers in Italian, English, French, German, and Spanish. The actual parts tables run from group 1 through group 12 or more, depending on the machine configuration. Each table has a part number column, description, quantity per assembly, and the original Dieci code. If you’ve ever tried to find a part for an Italian telehandler without a factory catalog, you know that the Italian aftermarket often lists “equivalent” parts that aren’t equivalent. This book kills that problem. The drawings are scanned from the original printing – not re-drawn, not simplified. What you see is what Dieci sends to its dealers.

FAQ

Does this catalog include torque specifications for bolts?

No. Torque specs are in the service manual, not the parts catalog. This book gives you the part number of the bolt itself – its thread pitch, length, and part code – but not the tightening torque.

Can I use this catalog to order parts directly from Dieci?

Yes. The part numbers match the Dieci spare parts system. Call their assistance office at +39 0522 869611 and quote the code from the catalog. They will confirm availability.

What is the difference between this OEM catalog and a third-party PDF?

Third-party PDFs often omit the revision number, skip optional parts, and use redrawn images that miss key markings. This is a direct scan of the 2008 Dieci release – every page, every group note, every language warning exactly as printed.

How do I find the part number for the boom hydraulic cylinder seal kit?

Go to the boom group section. The exploded drawing shows the cylinder assembly. Each component has an item number. Match it to the parts table – the seal kit will be listed as a separate line with its own part code. Order that code.

Stop chasing aftermarket part numbers that don’t fit. The Dieci Agri Star 37.8 2008 Parts Catalog puts the factory’s own parts data in your hands – 231 pages of exploded views, group tables, and original codes. Access the Factory Manual and keep it on the tablet in the cab. When something breaks, you open the catalog, match the part code, and call Dieci with the right number. That’s how you keep a telehandler running past 10,000 hours.
