HMF 2400, SHERPA, 2440 Parts Catalog – Field Notes from a Lifetime of Torque Wrenches

You’re pulling a front axle on a 2400. Bolts are rusted, shims scattered across the bench, and the aftermarket parts diagram you pulled off the internet shows the wrong differential housing. I’ve been there. That’s why this HMF 2400, SHERPA, 2440 Parts Catalog sits on the rack in my shop next to the Snap-on boxes. 558 pages of OEM factory part numbers, exploded views, and cross-references that match what HMF stamped on the castings. No translation errors, no guesses.

This thing covers three distinct models—2400, SHERPA, and 2440—with separate sections for each variant. Look at the table of contents: Front axle and steering runs from page 235 through 294, with dedicated pages for the SHERPA version (237, 258-272) and the standard 4WD setup. Rear axle and brakes start at page 186 and go through 227, including the differential, half-shafts, brake master cylinder, and trailer brake kits for Italy and France. Cab and body sections take up pages 424-461, covering everything from the roll cage and platform to the AC compressor, windshield, roof panels, and passenger seat kit.

Don’t expect a repair manual—this is a parts catalog. That means every page is a diagram with reference numbers keyed to a parts list. Need the steering distributor for a SHERPA? Page 280 gives you the exploded view, page 283 lists the part numbers. Want the brake actuation command for the rear brakes? Page 207 shows the pedal linkage and the actuator control. The index at the back (alfabetico) is alphabetical, so you can find any component by name instead of hunting through sections.

Front Axle Exploded Views: SHERPA vs Standard

Pages 235 and 237 split front wheels and rims between standard and SHERPA models. Then pages 240-254 cover the standard 4WD front axle—body, supports, differential (two pages each), final reduction, and brake assembly. SHERPA gets its own run from 258 to 272, with the same granularity but different part numbers. If you’re ordering bearings for a SHERPA front axle, you use page 261 for the differential and page 267 for the final reduction. Mixing them up means a trip back to the parts counter.

Steering hydraulic lines are on pages 274-276, steering distributor on 280-283, steering cylinder on 286-289 (separate pages for SHERPA), and the adjustable steering column on 291-294. That’s a complete hydraulic steering system breakdown. Every O-ring, every hose fitting, every bracket is numbered.

Rear Axle and Brake Components – What’s Covered

Rear axle starts at page 186 with the central housing, then moves to the carrier and wheel hubs (standard on 188, SHERPA on 191). Differential is on 193, half-shafts on 196 (standard) and 198 (SHERPA). Differential lock control (front and rear) is on 199. Brakes start at page 203 with pedals, linkage, and fluid reservoir; page 205 continues the pedal assembly; page 207 covers the brake actuator command; page 210 shows front and rear brake lines; page 212 is the master cylinder; page 213 the wheel cylinder; page 214 the hand brake. Trailer brake kits for Italy (page 220) and France (page 224) are included—important if you’re retrofitting a tractor that came without them.

Rear wheels and rims are on page 227. That’s a lot of detail for a single axle group. When I had a 2440 come in with a blown differential lock actuator, page 199 saved me an hour of fishing for the right spring and piston.

7 Major Sections in This Catalog

The catalog splits into seven main areas: Mechanical Accessories (pages 463-473), Cab and Body (424-461), Front Axle and Steering (235-294), Rear Axle and Brakes (186-227), plus smaller sections for the chassis weight brackets, front hitch, drawbar, tool kit, and hazard triangle. Every section has its own page range, and the alphabetical index at the end lets you jump straight to the part you need.

For example, if you need the cab frame and platform, page 424 shows the structure and page 425 lists accessories like the passenger seat (page 428). Cab trim and lining are on 431-432, AC compressor and condenser on 435-437, windshield on 440, AC unit on 443-446, doors on 448, rear window on 451, roof panel on 454-457. There’s even a cab equipment kit on page 460 and a general cab kit on page 461.

Why OEM Parts Catalogs Beat Aftermarket

I’ve used aftermarket parts books that combine three different model years into one drawing—and half the callouts are wrong. This is an original HMF factory print. The part numbers match the casting numbers on your actual components. When the catalog says “page 261, item 12” for a differential shim in a SHERPA, that shim is the one you need. No reprints, no third-party editing. If you’re buying used parts or rebuilding a machine that’s been swapped around, this catalog lets you cross-reference the old part number against the exploded view to confirm fitment.

Aftermarket catalogs also skip the minor accessories. This one includes the tool kit (page 471) and the hazard triangle and license plates (page 473). That matters when you’re restoring a tractor for a collector or prepping one for road use.

Cab Interior: Trim, AC, and Windows

Pages 424-461 give you every cab component. The frame and platform on 424-425, passenger seat on 428, trim on 431-432, AC compressor and condenser on 435-437, windshield on 440, AC unit on 443-446, doors on 448, rear window on 451, roof panel on 454-457. If you need to replace a door seal or a window latch, the part number is right there. The AC condenser support bracket is on page 437—don’t waste time measuring a bracket that might be bent.

One thing I learned the hard way: the SHERPA cab roof panel (page 454) is different from the standard 2400 roof. The catalog shows both, with separate part numbers. If you order the wrong one, it won’t line up with the roll cage mounting holes.

Frequently Asked Questions

Does this parts catalog include repair procedures?

No. This is a parts catalog, not a service manual. It shows exploded views and part numbers for ordering components. You need the separate repair manual for torque specs and assembly instructions.

Are the part numbers still current for 2025?

Some part numbers may have been superseded. HMF updates its numbering over time. Use this catalog to identify the original part, then cross-check with your dealer for current numbers.

Can I use this catalog for a non-SHERPA 2400?

Yes. The catalog includes separate sections for standard 2400/2440 and SHERPA models. Front axle, rear axle, steering, and cab all have dedicated pages for each variant. Just pay attention to the headings.

How do I navigate 558 pages efficiently?

Use the alphabetical index at the back of the PDF. Type the Italian component name (e.g., “circondario” for bearing) and it gives you the page number. Or browse the table of contents grouped by system.

Whether you’re rebuilding a SHERPA front axle from scratch or hunting down a single steering cylinder seal for a 2400, this catalog puts the right part in your hand on the first order. No wasted trips to the dealer, no returns because the drawing doesn’t match. Access the factory manual and put it on your tablet or print the sections you need.
