Bantam 424C, 426C 1980 Parts Catalog

I’ve been torquing bolts for 28 years, and nothing kills a job faster than ordering the wrong part for an old crane. You pull the old bracket, measure it twice, then spend an hour cross-referencing numbers from someone’s illegible scribble. That stops here. The Bantam 424C, 426C 1980 Parts Catalog gives you the factory part numbers directly from the OEM — you skip the guesswork and avoid aftermarket reinterpretation.

Frame, Deck, and Fuel Tank Assembly – Group 1 Coverage

Group 1 covers the frame, deck, fenders, and fuel tank. Pages 1.1 and 1.2 show part numbers for left and right rear fenders, deck plates, running boards, and all the hardware like capscrews and lockwashers. Notice the instruction at the bottom of every page: "WHEN ORDERING, SPECIFY BANTAM SERIAL NUMBER, PART NUMBER AND NAME OF PART REQUIRED." That is not a suggestion. If you call a parts counter without the serial number, you will get the wrong piece. This catalog includes two wheelbase variants: 176″ and 224″. If you have a 424C or 426C, you need to match the frame part number to your serial number range. The table on page 1.1 breaks it down by prior to serial #50009 and after.

Get the Correct Part Numbers for Engine, Clutch, and Cooling

The next section covers the engine, clutch, cooling, and exhaust. These components are often swapped or replaced with non-OEM parts, and this catalog gives you the exact Bantam part numbers. For example, the engine section lists options for the Detroit Diesel 6V-53N and 6V-53T, as well as the IHC (International Harvester) engine. If you have a 426C with the turbo, you need the right deck panel – see page 1.2 for the left deck specific to the 6V-53T. The catalog also includes the clutch assembly, radiator, and exhaust manifold parts. Do not rely on a generic parts book for these; the factory manual is the only source that matches the chassis.

What Does the Parts Catalog Include for Transmission and Axles?

Transmission, transfer case, auxiliary transmission, drive shafts, axle suspension, front and rear axles, wheels, hubs, and drums – all of these are broken out into separate groups (Groups 4 through 8). The catalog provides part numbers for the entire drivetrain. If you need a new axle suspension bushing or a wheel hub for a 424C, you look it up by the exploded diagram reference numbers on the corresponding page. The suspension group (Axle Suspension 6) lists specific part numbers for the leaf springs, shackles, and mounting brackets. This is where the 152 pages of this catalog earn their keep – you get a complete inventory of every bolt, washer, and seal for the running gear.

Electrical System: Wiring and Component Diagrams

Group 12 covers the electrical system. While this is a parts catalog and not a wiring schematic, it lists every electrical component with its OEM part number: alternator, starter, switches, lights, harness connectors. If you are chasing an electrical gremlin on a Bantam crane, having the correct part number for a relay or a light assembly saves you from ordering the wrong voltage rating. The catalog includes multiple variations for different serial number ranges, so you must match your machine’s serial number to the part number table.

152 Pages of Factory-Issued Part Lists

At 152 pages, this 1980 catalog is the official Bantam Division of Koehring Company publication. It was printed in the USA, and every part number came from the factory engineering department. Compare that to a third-party aftermarket catalog that may have merged numbers from multiple years or made assumptions. When you order parts using this catalog, you order what the factory intended. The pages are organized by group, with an index at the front. Each group has its own page numbering (e.g., Group 1 starts at page 1.1). The catalog also includes revision dates – for example, Group 1 was revised September 1980, and Group 2 (hydraulic outriggers) was revised December 1981. That tells you this is a living document, updated as parts changed.

Part numbers don’t lie.

Who needs this? Anyone maintaining a Bantam 424C or 426C crane. Home garage guys who bought an old machine for a project. Small shop owners who don’t want to pay dealer markup on parts. If you have a serial number and a busted fuel tank, you can find the right part in about two minutes. That’s the value.

I’ve seen aftermarket parts lists that transposed digits or left out superseded numbers. This is the original factory document – Litho in USA, Part No. 2036. You can trust it because it came from the same engineers who designed the crane. For background on the broader context of industrial equipment, check Automotive Industry Overview. Understanding how these machines fit into the Automotive Industry Overview helps you appreciate why factory specs matter.

If you need parts for other Bantam models, we have the Koehring Bantam S488, S588, S688 Parts Catalog | OEM Factory Manual and the Koehring Bantam C-744, 744 1975 Parts Catalog – OEM Factory Manual. For a smaller unit, see the Bantam TK-450 Parts Catalog – OEM Factory Parts List.

Frequently Asked Questions

Does this catalog cover both the 424C and 426C models?

Yes, it covers both models. The part numbers are listed for each model with serial number breaks.

Are torque specifications included in this parts catalog?

No. This is a parts catalog only – it lists part numbers, not service procedures. For torque specs, you need the factory service manual.

Can I use this catalog for a Bantam 424C built after 1981?

The catalog includes revisions through December 1981 for the hydraulic outriggers and other groups. If your machine’s serial number is higher than the ones listed, parts may have been superseded by later engineering changes. You should check for later supplements issued by Koehring. The frame group, for example, distinguishes between prior to serial #50009 and after. Later production beyond the scope of this catalog may require cross-referencing to updated part numbers from the factory. Always verify with your serial number against the range tables in each group.

Is the PDF searchable by part number?

The digital copy has OCR text embedded, so you can search for part numbers within the PDF. That speeds up finding specific items in the index.

Access the factory manual and keep it on your tablet or print it for the shop. Having the correct part numbers before you start saves time and keeps your Bantam running.
