Massey Ferguson MF 187 Parts Catalog – 297 Pages of Factory Data

You’ve pulled a busted knife section off an MF 187 header, you need the exact replacement, and the local dealer’s parts guy is reading off a screen that might as well be in code. The aftermarket microfiche you obtained shows a blurry drawing and a part number that doesn’t match anything on the shelf. That’s the kind of wasted afternoon that costs you money.

This Massey Ferguson MF 187 Parts Catalog is the factory bindery print — 297 pages, no photocopy, no third-party rekey. Every part number, every quantity, every comment like “SERATED VERSION” or “SMOOTH VERSION” comes straight from the Massey Ferguson engineering drawing. You get the same exploded-view diagrams the dealer’s parts counter uses, but on your own bench.

Let me show you what’s inside and why you need it before you pull that first bolt.

297 Pages of Factory Part Numbers – Not a Summary

Most aftermarket parts lists give you a table of numbers; this one gives you 297 pages of itemized breakdowns. The knife assembly for an 8-foot cutterbar takes up pages 2–3 in the actual document — item 1 is the knife (403320M93), item 2 is the section (790863X1), right down to the rivet count (136 for the A version, 68 for B). You don’t guess how many rivets you need. The factory says 136. You order 136.

Flip to the 10-foot cutterbar section and the numbers change: knife is 1723545M92, sections are 790863M1, rivets jump to 148. The catalog tracks both variants in parallel because the MF 187 shipped with different header widths. No ambiguity.

Knife Assembly Breakdown: 8′ vs 10′ Cutterbars

You’re working on the header and the bearing needle (item 11 on the 10-foot diagram, part 833083M1) is dry. The catalog shows you exactly which grease nipple (item 14, 13811X) fits that bearing. If you try to use a generic needle bearing from the bin, you’re asking for a header knock that chews up the knife head in a week. This book gives you the OEM cross-reference: seal part 831225M1, bearing 239242X1, spring 785583M1. Order them together, replace them together.

Don’t overlook the “Comments” column — it’s where Massey tells you “NOT SERVICED, ORDER ITEM 26” for that knotter hook assembly. That saves you buying a part you don’t need.

How to Use This Catalog: From Diagram to Order

Find the assembly you’re working on (say, “KNIFE – 10’”), locate the item number in the drawing, read across to the part number and qty. Write down the part number — including the suffix, because M91 vs M93 changes the entire knife assembly. Then call your supplier. If they try to substitute a different revision, you have the factory document to tell them exactly what you need.

Page 4 in the catalog shows the 10-foot knife listing with item 3 (148 rivets) and item 6 (16 rivets for the support). That kind of detail matters when you’re rebuilding a header in the field and need to know if the rivet kit you grabbed is complete.

Who Needs a Factory Parts Catalog?

If you own an MF 187 combine and do your own maintenance, you need this. If you’re a shop that works on Massey Ferguson equipment, you need this on the bench, not in a drawer. The beginner who’s never ordered a combine part before will save hours — the book shows you the part, the number, and where it goes. The experienced tech uses it to cross-check aftermarket numbers and avoid buying the wrong section because the dealer’s computer showed a superseded number.

OEM vs Aftermarket: Why Factory Data Matters

Aftermarket catalogs renumber parts, combine revisions, and drop comments. I’ve seen a third-party list that called the knife section “BLADE” and left off the quantity. Waste of time. The OEM catalog lists every rivet (391493X1), every lock washer (339376X1), every metric nut (339402X1) with the exact count. When you’re ordering for a 10-foot header and the manual says “78 Section (A)” for item 4, you trust that number because it came from the drawling that built the machine.

There’s a reason Massey Ferguson doesn’t sell generic part lists. They print this catalog so their dealers — and you — can get the job right the first time. The Automotive Industry Overview on Wikipedia shows how complex modern equipment is; a combine’s header is no different. Automotive Industry Overview”>Wikipedia’s automotive industry page reinforces why factory documentation is the only reliable source for critical components.
