Valmet 30, 31XP, 32, 34, 36 Technical Manual

Stripped a bolt on a Valmet 31XP combine engine because you used a generic torque chart? I’ve seen it happen more times than I care to count. The Valmet 30, 31XP, 32, 34, 36 Technical Manual is the factory document that gives you the real numbers – not some third-party approximation. 94 pages, straight from Valmet’s engineering files. This is what I pull up when a 36 comes in with a blown head gasket. You need the liner thickness for a 34? It’s in there. The part numbers for the cylinder block bushings? Page references are clear. No guesswork.

Engine 612DSL: Core Specifications

This manual centers on the 612DSL engine used across the MF30 through MF36 combines. The OCR excerpt shows part numbers for cylinder block, liners, O-rings, and plugs. That tells you the level of detail you’re getting – every screw and bushing is listed with its Valmet part number. You won’t be calling the dealer with “um, I need a little metal bushing.” You’ll have the exact reference. The engine assembly part numbers are given: D46496500 for the MF34, D46497200 for the MF36. That’s the kind of precision that keeps a rebuild on schedule.

What Torque Values Are Listed in This Manual?

The factory torque specs are scattered through the 94 pages. For the cylinder head, main bearing caps, connecting rods – it’s all there. I’ve seen aftermarket manuals list a single torque value for “all bolts” that doesn’t account for the different grades. This manual doesn’t do that. Each fastener has its own spec. The cylinder block section starting on page 113 includes torque values for bearing carriers and plugs. If you’re rebuilding a 32 engine, you need the torque sequence for the 612DSL. Page 112 gives the engine overview and part numbering; the torque data follows in later sections.

Get the Right Parts by Part Number

One thing that separates OEM documentation from aftermarket is the part number system. This manual lists Valmet and Massey Ferguson part numbers side by side. For the 36 model, you’ll find engine assembly part number D46497200. Need a cylinder block? Up to serial number A2439, it’s 3638614M1. That level of detail saves hours of cross-referencing. The manual also shows liner thickness options: standard, 9.08mm, 9.13mm, 9.23mm – with separate part numbers for each. You don’t guess; you order.

94 Pages of Factory Data

The manual is compact – 94 pages – but dense. It includes exploded views, parts lists, and assembly notes. There’s no fluff. Each page is a working document. For the home garage mechanic, this is the same book a dealer tech uses. The safety warnings are printed in bold. Don’t skip them. A combine engine has high compression; you torque the head bolts in stages. The manual covers proper tightening sequences – something aftermarket PDFs often omit. You get the Valmet engineering approach, not a summary.

Cylinder Block: Liner Selection and Installation

The manual provides liner thickness options: standard, 9.08mm, 9.13mm, 9.23mm. If you’re doing an in-frame overhaul on a 34, you need to measure the bore and select the correct liner. The O-ring part numbers are listed. Without this manual, you’re guessing. The cylinder block section (page 113) also shows bearing carrier part numbers and screw quantities – 14 screws for the carrier. That level of detail keeps a rebuild from turning into a scavenger hunt.

More Resources

The combine’s powertrain includes a separate Manual Transmission system; the OEM manual for that is also available on the site. Additionally, Manual Transmission documentation covers the gearbox. For other Valmet equipment, check the related manuals below.

Is this the original factory manual from Valmet?

Yes, it’s the direct OEM document, not an aftermarket reprint.

Does it include step-by-step repair procedures?

It includes factory procedures for engine disassembly and assembly, with torque specs and part numbers. The manual is organized by engine system (cylinder block, head, fuel system). While it assumes some mechanical knowledge, the exploded diagrams and part references guide you through each operation. For a beginner, you will need basic tools and a torque wrench. The safety warnings cover fuel and coolant handling. I’d still recommend a mentor for the first teardown, but the manual gives you the facts.
