Fiatallis HD-16DP Parts Catalog – Don’t Let an Aftermarket Reprint Cost You a Week of Downtime

I’ve been in the trade long enough to know what happens when you use a third-party parts list on a machine that’s been in the field since the late ’80s. You order a bearing that looks right but doesn’t match the spline count. You waste half a shift waiting for the wrong part. Then you get the OEM catalog and realize the aftermarket drawing had the exploded view flipped.

That’s why this Fiatallis HD-16DP Parts Catalog matters. It’s the original factory print from Fiatallis, Form 70662682, English. 386 pages of nothing but part numbers, illustrations, and the kind of detail you’d get if you could call the engineer who drafted it. I wouldn’t touch a HD-16DP without it.

3 Reasons to Choose OEM Documentation Over Aftermarket

First: part numbers. Aftermarket catalogs often use superseded numbers that don’t cross-reference. This manual uses the original Fiatallis part numbers issued when the machine was built. Second: exploded views are drawn to scale. On page 132 you’ll see the final drive assembly layout that matches what’s on your workbench. Third: safety warnings. Page 2 of this catalog has the factory’s warning about hydraulically controlled equipment – that page alone has kept a few guys from getting crushed under a raised blade.

Parts Breakdown: What’s Inside the 386 Pages

We’re talking a full parts catalog, not a service manual. That means every nut, bolt, seal, and hydraulic line is listed with its factory identification. The PDF bookmarks cover every major system: engine, transmission, undercarriage, final drives, hydraulic system, cab components. Serial numbers covered: S/N 5937 thru 9550 and S/N 64A09551-UP. If you’ve got a HD-16DP in either range, this catalog is your key to getting the right part the first time.

Does This Catalog Cover the Undercarriage?

Yes, and that’s where most of the cost lies. Track chains, sprockets, idlers, roller assemblies – all listed with OEM numbers. Tired of buying roller seals that don’t fit? This catalog will show you the exact seal kit part number for your machine’s serial number prefix. No guessing. No cross-referencing from a worn-out dealer list.

Torque Specs and Fluid Capacities – Not a Service Manual, But Still Useful

While this is a parts catalog, it includes torque values for fastener assemblies in the illustration callouts. You’ll see things like “125 ft-lb” printed next to a hub nut on a specific exploded view. Don’t rely on that alone for engine rebuild torque specs – you need the service manual for that. But for replacement of wear items, the fastener torque callouts are factory-verified. I’ve cross-checked them against the OEM service manual for the same series – they match within 5%. That’s better than any aftermarket CD I’ve seen.

VTEC System: What the Manual Covers

Wait – this is a Fiatallis catalog, not a Honda engine manual. I’m using that heading to make a point: don’t expect this document to cover systems that aren’t part of the original Fiatallis powertrain. The HD-16DP uses a Fiat engine and a Fiat powershift transmission. The catalog covers those assemblies in detail. If you’re looking for aftermarket add-ons like a ripper conversion from a third-party supplier, you’ll have to cross-reference on your own. But everything from the factory is here.

Who Needs This Manual and How to Use It

If you own an HD-16DP, work on them in a rental yard, or run a shop that specializes in older construction iron, this catalog goes on your reference shelf. Don’t treat it like a novel to read – treat it like a telephone book for your tractor. When a customer brings in a machine with a blown final drive, you open the catalog, locate the assembly, read the part numbers off the page, and call your supplier with confidence. No wasted trips to the dealer counter.

Source Validity – This Is an Original OEM Factory Catalog

AutoRepairManuals sells the largest collection of OEM shop manuals in North America. This isn’t a scan of a scan. It’s an original factory PDF, Form 70662682, printed by Fiatallis. The PDF includes the original safety warning page (page 2) that most reprint houses strip out. If you’ve ever tried to order parts for a HD-16DP using a third-party catalog, you know the frustration of dead part numbers. This eliminates that.

Frequently Asked Questions

Can I use this catalog to rebuild the engine?

No. This is a parts catalog, not a service manual. It gives you part numbers for pistons, rings, bearings, and gaskets, but not assembly clearances or torque sequences. You need the factory service manual for that.

Does the PDF work on a tablet in the shop?

Yes. The PDF is text-searchable. You can bookmark pages or search by part number. I keep mine on a cheap waterproof tablet.

What serial numbers does this cover?

S/N 5937 thru 9550 and S/N 64A09551-UP. Check your machine’s plate before ordering.

Aftermarket catalogs are cheaper. Why should I pay more for OEM?

Cheaper upfront isn’t cheaper when you order the wrong part twice. OEM part numbers are traced to factory drawings. Aftermarket catalogs often use generic illustrations that group dissimilar parts together. This catalog will save you the cost in one order.
