Massey-Harris PONY 812 Parts Catalog – 36 Pages of Factory Specs

If you are trying to track down a part for a Massey-Harris PONY 812 without the factory parts catalog, you are working blind. I have seen guys spend an afternoon chasing a bolt that crosses to the wrong thread pitch because some third-party list got it wrong. This is the original Parts Catalog – 36 pages of factory-issued part numbers, figure references, and ordering instructions. No translations, no guesses. Just the list Massey-Harris sent to dealers.

Original French Factory Parts List – Not a Reprint

You get the actual scanned pages from the OEM document. Page 2 of the catalog prints the ordering rules in French: you must include tractor number, engine number, part number, description, and quantity. That is not a suggestion – it is how Massey-Harris built their inventory system. Ignore it and you will probably get the wrong piece. The catalog itself is in French, but part numbers are universal. If you cannot read French, you still identify every component by the figure number and the part code. I have used bilingual catalogs for twenty years; the numbers do the work.

BATI PRINCIPAL Frame Section: Page 3 Breakdown

Page 3 opens with the main frame (Bâti Principal). It lists grease fittings, washers, bolts, and brackets with exact part numbers like 623 406 M1 and 36 004 X. Each line gives the part description and a figure number. If you need a new lever double or a self-lubricating bushing (623 719 M1), the catalog shows you exactly which drawing to look at. This is not a generic diagram – these are the original production drawings that Massey-Harris used on the line. The page also notes serial number breakpoints, like “à partir du tracteur No de Série 3 000” for certain bolt changes. You miss that detail and you bolt a pre-3000 bracket onto a post-3000 frame. That costs you time.

Using This Catalog with Your PONY 812

The catalog covers every major assembly: engine supports (Supports du Moteur), steering box brackets, clutch housing, front axle, and more. Each section starts with an assembly name and then a table of parts. The part numbers follow the original Massey-Harris system – you feed those into a dealer parts lookup or a salvage yard and get the correct item. If you are restoring a PONY 812, the 36 pages give you the complete parts breakdown. I recommend you print out the pages you need and tape them to the bench. That keeps grease off the screen and your eyes on the numbers.

For related manuals, check the Massey-Harris 744D Illustrated Repair Parts List if you work on that model, or the Massey-Harris Pony Parts Catalog for other Pony variants. The Massey-Harris Tractors 20, 20K, 22, 22K Use & Maintenance manual covers operation and service for similar vintage tractors.

Why Aftermarket Parts Lists Fail

Aftermarket catalogs often merge multiple model years, drop serial number breaks, or substitute modern fasteners that do not fit the original thread pitch. This factory catalog lists every part with the original Massey-Harris number. It also shows the exact figure number so you visually confirm the part shape. I have had a 50% return rate on aftermarket parts until I started using OEM catalogs. The Automotive Industry Overview explains how legacy fastener standards vary; this catalog documents what your PONY 812 actually left the factory with.

3 Systems Where Exact Part Numbers Matter

1. Engine supports (Supports du Moteur): Page 4 lists bolts like 623 463 M1 and 623 464 M1. These are not generic grade 5 bolts – they have specific shoulder lengths and thread engagement. Use the wrong one and the engine mount can loosen.
2. Steering linkage: The double lever (levier double) and its bushings – part 623 719 M1 (self-lubricating) – must match. The catalog shows the figure number for the lever assembly so you order the correct bushing.
3. Clutch housing and frame bolts: Bolts like 851 183 M2 have a note “à partir du tracteur No de Série 3 000”. If you ignore the serial number, the bolt might be too short or too long. That costs you a stripped thread.

Reference page 3 for the main frame table and page 2 for the ordering instructions. Those two pages alone will save you from ordering the wrong boulon hexagonal.

Frequently Asked Questions

Does this catalog include internal engine parts like pistons and rings?

The catalog covers the complete tractor including engine supports and frame components, but it does not go into detailed engine internal parts such as pistons, rings, or cylinder heads beyond the mounting brackets. For a full engine overhaul you would need the Massey-Harris service manual that includes exploded views of the engine block. This parts catalog is meant to identify and order replacement pieces by number. The engine section lists the mounting hardware and the fuel system components (regulator, lines) but not reciprocating parts. If you need a piston, you will have to cross-reference the part number from a master parts book or contact a specialist.

Is the catalog written in English?

No, it is in French. All part numbers and figure references are universal, so language does not block part identification.

Automotive Industry Overview is a useful reference for understanding thread standards if you need to cross a part to a modern equivalent. But for the Massey-Harris PONY 812, the best tool is the original factory documentation. Access the Factory Manual and put it on your tablet or print it. That 36-page PDF will sit on your bench next to the torque wrench where it belongs.
