Massey Ferguson 7242 Parts Catalog – 410 Pages of Factory Specs

You’re knee-deep in a header rebuild on a Massey Ferguson 7242 combine, and the parts guy says, “We need the part number.” You pull out a greasy finger to point at the exploded view – but you don’t have one. That’s where this Parts Catalog comes in. 410 pages of factory-issued part numbers, not some aftermarket copy with “compatible” junk. I’ve seen too many guys order a D28230292 shim off a third-party list and get a washer that doesn’t fit. This manual gives you the exact OEM number – period.

I’ve been wrenching on combines long enough to know that when the parts catalog is wrong, the machine sits. And sitting costs money. This book covers the Massey Ferguson 7242 from the knife head to the stone trap. The OCR excerpt shows the “Knives And Fingers – Freeflow” section starting on page 001-0001. Real part numbers like D44104500 for the finger (12-foot header) and D28283011 for the knife head. No guessing. No “use this if you can’t find the original.” Factory spec, right down to the clip lengths for 12-foot, 14-foot, and 16-foot headers.

Knives and Fingers: Factory Part Numbers for the Header

The header is where the money is made. If you’re replacing a finger on a 12-foot Freeflow, the manual lists D44104500 – 25 of them. For the right-hand finger, D44104600. The left-hand? D44104700. These are the exact numbers you read to the parts counter. No cross-referencing. No calling three dealers. The manual also gives you the shim (D28230292), the O-ring (D45483000), and the bolt (D40551500). When you’re pulling a stone trap, you need the guard part numbers: D28230842 for 14-foot, D28230845 for 16-foot. It’s all in there.

Stone Trap Assembly and Fastener Callouts

Stone traps take a beating. The manual breaks down the left-hand and right-hand stone traps (D18283704 for 16-foot, D18283701 for right-hand). You’ll also find the ear lifter (D49040200), spring (D49040400), and roller (D49040600). The fastener specs are there too: hex socket screw M10 x 50 (339019X1), locknut (D41017500, 3 required). None of this “tighten until it feels right” garbage. The factory gives you the fastener grade and part number so you can order the right hardware. If you’re replacing a knife back, the manual shows D28281488 for 12-foot, D28281489 for 14-foot, D28281490 for 16-foot. 2 per header. Do it right the first time.

Does This Manual Cover the Full Combine?

Yes – the title says “MF 7242 COMBINE – 1637439” and the booklet covers the entire machine. The 410 pages include exploded diagrams for every major assembly: feeder house, threshing, cleaning, grain handling, and the cab. But the excerpt we have shows the header section in detail. If you need the charge pressure for the hydraulic system, you’ll find it in the service manual – this is a parts catalog, not a repair manual. But for ordering parts, it’s the only source you should trust. The Automotive Industry Overview might tell you about trends, but this catalog tells you what bolt to use.

3 Reasons to Use Factory OEM Documentation

First, aftermarket catalogs often combine multiple models into one listing, leading to wrong parts. Second, OEM part numbers are verified against the original engineering drawings. Third, the fastener callouts – like “Hex. Sock. Screw M8 x 30” (339337X1) – are exact. You won’t find a note saying “may substitute” in a factory manual. I’ve seen a guy strip a header drive because he used a Grade 5 bolt instead of the factory Grade 8. This manual prevents that. If you’re working on a Massey Ferguson 7242, get the real thing.

Torque Specs and Fastener Grades

While the parts catalog doesn’t list torque values for every bolt (that’s in the service manual), it does list the exact fastener part number. For example, the locknut M8 (394367X1) – 12 required. The hex socket screw M10 x 50 (339019X1). The washer D20400414. When you order the OEM part, you get the correct grade. I’ve seen too many aftermarket suppliers sell a hardware kit with a mix of grades. If you’re rebuilding a knife head, you need the rivets D41306100 and D41306200. The catalog tells you “X” quantity – meaning order as needed. Don’t guess.

Source Validity: Factory OEM vs. Aftermarket Reprints

This is a direct scan of the original Massey Ferguson publication. The page numbering (001-0001) and the reference “D-ZAZA-007-B” match the factory layout. Aftermarket reprints often blur the diagrams, skip pages, or change part numbers. I’ve seen a “compatible” catalog list a D28283011 as a “universal knife head” – it’s not. The factory manual has the exact dimensions. If you’re serious about keeping your combine running, you don’t buy a reprint. You buy the original. Automotive Industry Overview might give you background, but this manual gives you the bone.

FAQ – Two Questions

Does this manual include torque specifications for assembly?

No. This is a parts catalog, not a service manual. It lists part numbers, not torque values. For torque specs, you need the factory service manual for the 7242.

Can I use this manual to order parts for a 16-foot Freeflow header?

Yes. The manual covers 12-foot, 14-foot, and 16-foot headers. The part numbers for each are listed separately. For example, the finger for 16-foot is D44104500 with quantity 31. The guard for 16-foot is D28230845. The stone trap for 16-foot is D18283704. Just match your header length to the correct line in the table.

Look, I’ve been doing this long enough to know that a parts catalog is only as good as its accuracy. This one is 410 pages of factory-verified data. You want the right part the first time? Access the Factory Manual. No aftermarket nonsense. No reprints. Just the real Massey Ferguson documentation.
