Michigan 55A Parts Catalog

If you’re ordering parts for a Michigan 55A Series II tractor shovel, you need the factory-published parts breakdown — not some aftermarket PDF that guesses at part numbers. I’ve seen too many jobs held up because a guy ordered a Brake wheel cylinder based on a generic listing and got the wrong casting. This Parts Catalog is the original Clark Equipment document, 100 pages of exploded views, indexed by assembly, with genuine part numbers for every nut, seal, and Cylinder in the machine. It’s the same book the dealer parts counter uses. Michigan 55A Tractor Shovel Parts Manual 1394 covers the same ground if you need a bound copy, but this digital version gives you searchable text.

Why a Factory Parts Catalog Beats Aftermarket Copies

Aftermarket catalogs often leave out the little stuff — like the correct clip diagram or the Valve assembly for the bucket and boom control. This manual has a dedicated index page (see page 3) that lists every assembly from Accelerator Pedal to the Brake De-Clutch Valve. You get the exact part number for the Brake Assembly – Front (page 5) and the Brake Assembly – Parking (page 23). When you’re dealing with a 20,000-pound machine, guessing costs you time and money. Factory drawings show orientation, stack-up order, and which bolts go where.

100 Pages of Exploded Views and Part Numbers

Every page in this 100-page catalog is a high-resolution scan of the original print. The Cylinder sections — Boom Cylinder Assembly (page 60), Bucket Cylinder Assembly (page 23), Steering Cylinder Assembly (page 50) — are all there with callouts for seals, rods, and ports. Need the hydraulic pump for the bucket and boom? It’s on page 56, with a full parts list. The Brake system alone covers five different assemblies: front, rear, parking, master cylinder, and wheel cylinder. You won’t find this level of detail in a generic parts listing.

Brake Systems: Front, Rear, Parking – All Covered

The Brake section is a standout. You have separate pages for the Front Brake Assembly (page 5), Rear Brake Assembly (page 44), and Parking Brake Assembly (page 47). The Brake Controls (page 12) include the linkage and the De-Clutch Valve Assembly (page 5). If you’re rebuilding a brake master cylinder, the exploded view on page 62 lets you confirm every piston, spring, and seal before you order. I’ve used this manual to cross-reference part numbers for a customer’s 55A that had a seized wheel cylinder — saved us a week of waiting for the wrong part.

Cylinder and Valve Assemblies: Identification and Ordering

Three Cylinder types are explicitly covered: Boom, Bucket, and Steering. The Bucket and Boom Control Valve Assembly (page 70A) is a critical component — if you swap it with a non-OEM valve, the bucket leveling system won’t match. The manual also includes the Bucket Leveling Master Cylinder (page 58) and the Leveler Valve (page 58). For the steering system, the Steering Cylinder Assembly (page 50) and the Steering Pressure Relief Valve (page 53) are documented with OEM part numbers. Michigan 55A Tractor Shovel Parts Manual covers the same Series II, but if you have a Series I, check Michigan 55A & 55B Series I Tractor Shovel Parts Manual for the differences.

What You Need to Know Before You Order Parts

Before you call your dealer, write down the machine serial number — this manual references the MB 3625 series. The index on page 3 tells you the page for every assembly. For example, the Axle Assembly – Front Drive is on page 36, Differential and Carrier Assembly – Rear is on page 37. The Valve assemblies for the bucket and boom are on page 70A. If you’re working on a 55A that’s been modified, the original factory drawings will show you what was there from the factory. Automotive Industry Overview gives context on why OEM documentation matters across heavy equipment. For more on the history of Clark Equipment, check Automotive Industry Overview.

Frequently Asked Questions

Does this Parts Catalog include torque specifications for reassembly?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and exploded views. You need the separate service manual for torque values and procedures.

What is the difference between Series I and Series II for the 55A?

The Series II introduced changes to the steer axle mounting, boom cylinder, and some hydraulic valve assemblies. The index in this catalog is specific to Series II. If you have a Series I machine, you need the manual for that series – the part numbers will differ for many components, especially the brake controls and rear axle cradle.

Can I use this manual for a Michigan 55B?

No. The 55B has a different engine, transmission, and hydraulic system. The 55B parts catalog is a separate document. This manual is for the 55A only.

How do I read the part numbers in this catalog?

Each part number is printed in the exploded view with a leader line to the component. The index lists the page for each assembly. Cross-reference the machine serial number when ordering – some parts have superseded numbers. The manual includes a note on page 3 about always providing the serial number to your distributor.
