Dieci Pegasus 40.25 Parts Catalog

If you’ve ever ordered a hydraulic fitting based on a worn-out part number scribbled on a shop rag, you know the pain I’m talking about. The part shows up, it’s wrong, and now the machine sits while you wait for the next shipment. That stops when you have the Dieci Pegasus 40.25 Parts Catalog on your bench. This is the exact document the Dieci service department pulls up when you call in. 244 pages of factory drawings, group breakdowns, and part numbers that match the machine you’re working on. No translation errors, no third-party interpretation.

Why You Need the OEM Parts Catalog for the Pegasus 40.25

Aftermarket parts lists are a gamble. I’ve seen websites that claim to have part numbers for a Dieci telehandler, but when you dig into the PDF, it’s a generic hydraulic section slapped together. The OEM catalog is organized by groups and tables. Page 2 shows the CE declaration and contact info. That tells you this document comes straight from Dieci S.r.l. in Montecchio, Italy. If you’re sourcing parts for a 40.25, you want the same drawing the factory uses. Otherwise you’re ordering blind.

Catalog Organization: Groups, Tables, and Exploded Diagrams

Page 3 explains the structure: the catalogue is divided into groups. Each group contains spare parts tables. Those tables have drawings of the group with numbered callouts. The drawings may include optional accessories not mounted on the base machine. That’s important. If you see a circled item and it’s marked with a symbol (like a diamond or asterisk), check the symbol key on page 3. That key tells you if the part is sold only as a kit or if it’s still in the coding phase. Miss that symbol and you’ll order a single bolt that’s only available in a full seal kit. A waste of time.

Optional Items and Symbols You Must Understand

The catalog uses symbols to flag parts that are not available separately or are optional. For example, a part that shows # IN CODING PHASE means it hasn’t been assigned a final part number yet. Ordering it will get you a backorder notice. The symbol legend is right there on page 3. I’ve seen technicians skip that page and then call me asking why the part they ordered says “not available.” Read the symbols. It’s two minutes of your time that saves a week of waiting.

This catalog covers the entire Pegasus 40.25 telehandler — from the engine bay to the boom assembly. The groups are logical: you get the chassis, the transmission, the steering, the hydraulic system, the cab, the electrical harness. Each group’s table lists the part number, description, quantity, and any notes in four languages: Italian, English, Spanish, German. The OCR text shows “Catalogo RICAMBI / SPARE PARTS CATALOGUE / CATALOGO DE PIEZAS DE REPUESTO / CATALOGUE DE PIECES DETACHEES / ERSATZTEILKATALOG” — that’s the same four-language format throughout. No guessing what a “tubo flessibile” means when you can read “flexible hose” right next to it.

Does This Catalog Cover Your Specific Pegasus 40.25?

If your machine has the model plate that reads PEGASUS 40.25, this catalog matches. It covers base machine and common options. The manual includes a note that drawings may show optional items that aren’t on your specific machine. You need to verify the serial number or ask your dealer if an optional part is compatible. But the core groups — the engine, the hydraulics, the axles — are the same. If you’re working on a 40.25 with a different serial range, call Dieci service at +39 0522 869611. They’ll confirm compatibility. Don’t assume.

For a complete service data package, pair this catalog with the Dieci Pegasus Telehandler Operators Manual AXH1154/UK – Section: Cleaning The Wi”>Dieci Pegasus Telehandler Operators Manual AXH1154/UK – Section: Cleaning The Wi and the Dieci Pegasus 40.25 Operation and Maintenance Manual”>Dieci Pegasus 40.25 Operation and Maintenance Manual. The parts catalog gives you the numbers; the O&M manual gives you the procedures and torques. Together they’re unbeatable. If you also run a Zeus chassis, check the Dieci Zeus 37.7 Parts Catalog – OEM Spare Parts Manual”>Dieci Zeus 37.7 Parts Catalog – OEM Spare Parts Manual. Same meticulous factory documentation.

A quick word on source validity. This is an original Dieci publication, not a photocopy or a third-party scan. The file name DIECI_PEGASUS_4025_Parts_Catalog_it-en-es-de-24614018239.pdf confirms it. The document carries the official Dieci logo and contact information on every page. The automotive industry has a long history of counterfeit manuals — Automotive Industry Overview“>Automotive Industry Overview covers some of that history — but Dieci stamps each page with “DIE dieci” and a page number. You can verify authenticity by matching the layout on page 1. Real OEM documents never have misaligned text or missing symbols. Automotive Industry Overview”>Automotive Industry Overview is worth a read if you want to see how bad aftermarket parts docs can get. Stick with factory prints.

Is this the same as a service repair manual?

No. This is a parts catalog for ordering spares, not for overhauling the engine.

Can I use this catalog to order parts from my local Dieci dealer?

Yes. Every part number in this catalog is the one Dieci uses in their system. Give the dealer the group number and part number from the table, and they’ll process the order. The drawings also show the exploded view so you can confirm the correct orientation and quantity. Some dealers may ask for the machine’s serial number to double-check supersessions. That’s standard. The catalog includes a note that Dieci reserves the right to modify features for product improvement, so always verify with the service department if your serial number is outside the typical range. The phone number on page 2 is +39.0522.869.611 — that’s the technical assistance line. Use it if you run into a part that doesn’t match the drawing.

What languages are included in the catalog?

Italian, English, Spanish, and German. Every table and every footnote appears in all four languages.

How do I interpret the symbols next to part numbers?

Page 3 has a symbol key. Crosses, diamonds, and asterisks indicate parts not available separately, optional items, or items in coding phase. Read that page first.

Look, I’ve been wrenching on construction equipment for 28 years. When I need a part for a Dieci Pegasus 40.25, I don’t want to flip through a blurry scan that someone uploaded. I want the factory document. This catalog gives you 244 pages of verified part numbers, group tables, and exploded drawings.
