Clark-hurth 12B Parts Catalog – Stop Guessing, Get the Right Part Number

I’ve been turning wrenches for 28 years, and nothing burns my time like ordering the wrong part because some aftermarket catalog decided to swap a number. If you’re working on a Clark-hurth 12B tractor shovel – whether it’s the bucket cylinder, the brake master cylinder, or the battery wiring – you need the OEM part number, not a guess. This Clark-hurth 12B Parts Catalog is 214 pages of factory-sourced numbers, exploded diagrams, and ordering info that keeps your machine running instead of sitting. Clarke Equipment wrote this for dealers and shops. It’s not a reprint from some third-party that scanned a fuzzy copy. It’s the real deal.

Boom Cylinder Assembly and Brake Assembly – Page References You Can Trust

Two of the most common headaches on the 12B are the boom cylinder and the brake system. The boom cylinder assembly covers page 46 – that’s where you’ll find every seal, piston, and gland nut with the factory part number. The brake assembly lands on page 49, including the wheel cylinder, master cylinder, and lines. Don’t waste money on aftermarket cylinders that don’t match the bore or stroke. Use the original index to cross-reference.

Wiring and Battery – Don’t Hook It Up Wrong

The electrical system on these old tractors is simple but unforgiving. Battery and wiring are on page 56. The diagram shows the exact routing of battery cables, grounds, and the magnetic switch. I’ve seen guys short out a generator armature because they used a generic wiring schematic. This manual gives you the factory layout, so you know which terminal is hot and which is ground. No guessing.

214 Pages of Factory Part Numbers – Every System Covered

From the accelerator pedal linkage (gas on page 12, diesel on page 13) to the tire and wheel data on page 57, this catalog indexes every assembly. The transmission and converter assembly spans pages 17, 18, and 19. The control valve assembly and levers are on pages 41 through 45. That’s 214 pages of information you can’t get from a parts website that hasn’t seen the actual machine. Want the part number for the boom cylinder seal kit? It’s in the cylinder assembly section. Want the steering gear armature? Page 31. No fluff, no reprints.

Does This Parts Catalog Cover Gas and Diesel Engines?

Yes. The index splits engine accessories between gas and diesel versions. For gas: engine support parts, fan belt, generator armature – all on pages 1 and 2. For diesel: air cleaner (page 10), muffler (page 10), fuel tank and lines (page 15). The carburetor and ignition coil for gas are on page 2, while diesel uses glow plugs and a different fuel pump. This catalog covers both powertrain options, so you don’t have to buy two separate manuals.

Get the Right Part Number – Ordering Procedures

Inside the front cover, Clark tells you exactly how to order: provide the machine serial number, quantity, part number, and description. If you get the part and it’s wrong, check immediately for quantity, correctness, and condition – then contact your Michigan distributor. That’s what the factory says. I’ll add my own advice: always cross-reference the part number against the exploded diagram in the catalog before you order. One digit off on a brake cylinder and you’re waiting another week. This manual gives you the actual number, not a supersession list that may or may not fit.

Frequently Asked Questions

Q: Does this catalog include torque specs or repair procedures?

A: No. This is a parts catalog – it lists part numbers, quantities, and exploded views. For repair procedures, you need the service manual.

Q: How do I use the index to find a specific part?

A: The index starts on page 3. Look up the system name alphabetically – for example, “Brake Assembly” is under B, page 49. Then find the illustration for that assembly, read the callout numbers, and match them to the parts list. Always note the machine serial number; some later 12B units had superseded parts. The catalog lists both versions where applicable, so you need to confirm which applies to your serial range.

This is the manual you need if you want to stop burning money on incorrect parts. Access the Factory Manual and keep your 12B running like it left Benton Harbor.
