Fiat-allis 745H-B Parts Catalog – OEM Factory Manual (308 Pages)

Listen, I’ve been wrenching for 28 years, and the number one waste of time on a job is hunting down the right part number. You pull a worn-out valve or a leaking brake cylinder, and instead of ordering the correct replacement, you’re digging through three different aftermarket catalogs hoping the numbers match. That’s where the Fiat-allis 745H-B Parts Catalog comes in. This is the factory-issue document – 308 pages of exploded diagrams and OEM part numbers for the 745H-B wheel loader (serial numbers 72C02901 and 62Y02901 up). It’s not a reprint; it’s the original scan from Fiat-allis. If you’re rebuilding brakes, swapping a control valve, or tracking down that odd bracket, you need this on your bench.

308 Pages of Organized Part Data

The Fiat-allis 745H-B Parts Catalog is organized alphabetically by component, not by system. That means you look up “Brake” and find every brake-related assembly in one spot: front and rear Brake Assy. at page 73, parking Brake at page 142, Air Brake Lines at page 152, Brake Hydraulic Lines front and rear. Same for valve groups – Air Application Valve Assy. on page 154, Clutch Cut-Off Valve on page 253, Control Valve Assy. (hydraulic) page 222, Demand Valve Assy. page 181. Every entry has a page number referencing the exploded view with callouts. No flipping through generic sections. You go straight to the part.

That’s 308 pages of pure part data. Period.

Brake and Valve Systems: Factory Schematics

Brake systems on these loaders are critical – both service and parking. The catalog covers Brake Assy. (front & rear) page 73, Brake Hydraulic Lines (front) pages 166,173, and (rear) page 257. The Air Brake Lines (page 152) and Air Tank & Lines (page 158) are also there, along with the Alcohol Injector (page 162) for cold-weather air system protection. For hydraulics, the Control Valve Assy. (hydraulic) at page 222 is a key section – you get the entire spool valve bank with part numbers. The Air Application Valve Assy. (page 154) and Demand Valve Assy. (pages 181,188) are shown with every seal, spring, and plunger. If you’ve ever had a machine that won’t release the parking brake, you’ll appreciate having these OEM diagrams instead of a muddy aftermarket sketch.

Why a Factory Parts Catalog Beats Aftermarket?

Aftermarket parts catalogs copy from copies. I’ve seen them list wrong superseded numbers, leave out hardware, or show a drawing from a completely different model. This Fiat-allis 745H-B Parts Catalog is the real deal – originally printed by Fiat-allis for their dealers. Page 3 of the manual states: “All parts listed herein, which have no specific usage indicated, are applicable to all models.” It also explains that attaching parts like bolts and washers are indented right after the part they attach. That level of detail disappears in reprints. If you want to avoid ordering the wrong brake shoe or valve body, stick with the factory file.

If you work on other Fiat-allis machines, check out the Fiat-Allis HD41 Parts Catalog – 370-Page OEM Factory Manual for the HD41 dozer, or the Fiat-Allis 12G-B 1979 Parts Catalog – OEM Factory Manual 337 Pages for graders. Also the Fiat-allis 6G Parts Catalog – OEM Factory Manual 559 Pages is a monster for the 6G.

Using the Alphabetical Index

The TOC is an alphabetical index – no weird classification, just straight-up component names. Need a bucket cylinder? Look under “C” for Cylinder s Bucket (multi-purpose bucket) page 204, or under “D” for Dump Cylinder page 201. Looking for engine parts? The engine section spans pages 60, 62, and 63 – covering cylinder block, head, camshaft, crankshaft. Don’t know where the oil filter element is listed? It’s under “E” for Elements, Oil Filter page 46, 51, 52, 54. This index saves you from flipping through the whole file. For background on construction equipment documentation standards, see the Automotive Industry Overview.

What’s Included – Engine, Transmission, and Electrical

Besides brakes and valves, this Fiat-allis 745H-B Parts Catalog covers the entire machine. The Engine section (pages 60–63) details cylinder block, head, crankshaft, camshaft, and breather. Transmission components are on page 118, with the Control Valve Assy. (transmission) on page 114. The Electrical System (page 260) includes Alternator pages 272–273, Dash Light Assy. page 270, and Batteries & Cables page 285. Hydraulic Tank (page 218) and Boom (page 278) are also there. The Bucket section includes standard bucket page 249 and multi-purpose bucket page 204. Even the Cab Heater (page 146) and Cab & Wiper Assy. (page 248) are covered. This is a complete parts compendium for the 745H-B.

Source Authenticity – Original OEM Document

What you’re getting is a direct scan of Form 73066640 English – the official Fiat-allis 745H-B Parts Catalog. Page 1 carries the standard safety warning: “Study the operation and maintenance instruction manual thoroughly before starting, operating, maintaining, fueling or servicing this machine.” That’s printed in the original document. The engineering behind these machines is rooted in the Automotive Industry Overview. No third-party reprints, no missing pages. Just the factory reference.

Can I print this manual?

Yes, the PDF is fully printable.

Does this include service procedures or just parts?

This is a Parts Catalog, not a Service Manual. It lists every part with exploded views and part numbers. For repair steps, you need the separate Service Manuals listed on page 2 – Axle, Brakes & Air System, Bucket & Chassis, Electrical System, Engine, Fuel Injection, Hydraulic System, Power Steering, Transmission, and Turbocharger. The Parts Catalog is designed to be used alongside those service manuals to identify the exact components you need. Without the factory part numbers, you risk ordering the wrong seal, gear, or valve – and that costs downtime and cash.

Stop wasting time with mismatched parts and guesswork. You need the real thing. Access the Factory Manual from AutoRepairManuals and get your 745H-B back to work.
