New Holland 387 1981 Parts Catalog – 145-Page OEM Parts Identification

Description

You’re holding a parts catalog, not a repair manual. That’s the first thing to get straight. The New Holland 387 1981 Parts Catalog is 145 pages of factory-sourced part numbers, group breakdowns, and exploded views. If you’re trying to rebuild a Hayliner baler with aftermarket parts lists, you’ve already lost time and money. This is the same document Sperry New Holland issued in 1981 – issue 496943 – with the correct code columns and footnotes that tell you exactly which bolt, bearing, or belt fits your serial number range.

What the Group Numbers Tell You (Page 2)

Flip to page 2 and you see the issue replaces 496900. The catalog is organized into six major groups: 1–10, 11–21, 25–34, 35–38, and 39–45. Each group covers a functional area of the baler – from pickup to knotter. If you need a part for the feeder system, you go to group 11–21. Every exploded diagram in those sections references a part number and a code letter that ties to a specific serial number. Ignore the code column and you’ll order the wrong tine or shear pin. Page 5 explains the code system: the letters in the «CODE» column refer to machine serial numbers listed in footnotes.

Ordering Parts from the Dealer – Why Page 5 Matters

Page 5 contains the ordering instructions that most DIY guys skip. Sperry New Holland tells you to provide model number, serial number, part number, description, and quantity. Write down your baler’s serial number in the blank on page 5 – that single step prevents a wrong order. The machine details section also asks for tyre sizes and attachment model. If you call a dealer without that info, you get put on hold while they look it up. This catalog gives you the exact part number to read off the phone.

New Holland 387 1981 Parts Catalog Coverage vs Aftermarket

Aftermarket parts catalogs renumber components to fit generic listings. The New Holland 387 1981 Parts Catalog uses genuine Sperry New Holland numbers. Cross-reference a part from an aftermarket book and you might land on a substitute that doesn’t match the original clearance. This catalog shows original dimensions in footnotes – for example, if a bolt has a specific thread pitch, it’s noted in the N.B. column. I’ve seen too many guys buy a “compatible” roller and then have to grind it down. Stick with factory numbers. For other baler models, check the Ford New Holland 853 1993 Parts Catalog – OEM Baler Manual or the Ford New Holland 568 1991 Parts Catalog if you run a different setup.

Decoding the ‘Code’ Column and Footnotes

Look at any exploded view in this catalog. Next to the part number you see a letter – A, B, C, or a dash. That letter matches a footnote at the bottom of the page. The footnote says “Used before serial number X” or “Used after serial number Y”. If you skip that step, you buy a part that doesn’t fit your baler. The N.B. column flags special information – like “Includes lock washer” or “Order as an assembly”. Page 5 states that Sperry New Holland reserves the right to improve products, so a later serial number might have a different part. This catalog tells you exactly where the change happened.

Why a 1981 Catalog Still Works on Today’s Balers

New Holland balers from the late 70s and early 80s share most chassis and driveline components. A 1981 parts catalog covers the base unit up to a certain serial number range. If your baler was built within that range, the part numbers haven’t changed. The knotter assemblies, pickup tines, and bale chamber rollers are still available from dealers – but only if you give them the factory number. This catalog keeps you from ordering a “superseded” part that actually requires a different mounting bracket. The agricultural industry relies on decades-old parts continuity; even the broader Automotive Industry Overview recognizes that OEM documentation is the only reliable source for legacy equipment.

Three Tips for Using This Catalog on the Workbench

First, keep the catalog open to the group that matches the assembly you’re tearing down. Second, write the serial number of your baler on page 5 and reference it every time you order a part. Third, cross-check the code column against the footnotes before you buy – that ten-second check saves a return shipping fee. If you work on multiple New Holland models, the Ford New Holland 1915 Tractor 1993 Parts Catalog – Section: Supplement might be useful for shared engine or PTO parts. And for a broader look at how documentation standards apply across vehicle types, consider the Automotive Industry Overview page – same principle, different machine.

FAQ

Does this catalog include repair procedures or torque specs?

No. It is a parts catalog only. You need the service repair manual for disassembly, reassembly, and torque values.

How do I identify the correct part number from the exploded views?

Locate the group section covering your assembly (e.g., group 11-21 for feeder). Find the part in the exploded diagram, note the reference number, then look up that number in the parts list on the same page. Read across to the column showing part number, description, and quantity. Check the «CODE» letter – it tells you which serial number range that part applies to. If there is a footnote (usually at the bottom of the page), it may say “Used before serial number 12345” or “Used after serial number 67890”. If your baler falls outside that range, move to the next part number listed with a different code letter. Write down the full part number and order it from a dealer who stocks genuine Sperry New Holland parts.
