Koehring 424 Parts Catalog – Factory Parts Manual for the Carrier

Fighting with aftermarket parts lists that show a drawing but not the correct part number? Or worse, a generic number that doesn’t match the bolt pattern on your Koehring 424 carrier. That’s why you need the actual factory Koehring 424 Parts Catalog. Not a reprint from some third-party that scanned a photocopy. This is the original OEM document, 173 pages of part numbers, group indexes, and ordering instructions that Bantam/Koehring printed in the USA. If you’ve ever ordered a fuel tank gasket and got the wrong shape because the online list omitted the serial number range, you already know the headache. This catalog ends that guesswork with the exact factory group numbers and descriptions.

Frame and Fuel Tank Group: What You Get on Page 1

The Group Index starts with Frame, Deck, Fenders, Fuel Tank – that’s section 1. Page 1 of the catalog shows the serial number location (stamped brass plate in the cab) and the standard warranty statement. If you’re replacing a cracked fuel tank or repairing the deck, you need the right part number for your specific machine. The catalog groups parts by system, so you don’t have to flip through random pages. Each item lists the group number, part number, and description exactly as Koehring intended. No ambiguous “fits all” labels.

Engine, Clutch, Cooling, Exhaust – Section 2

Engine parts are in section 2 along with the clutch, cooling system, and exhaust. The catalog covers the base carrier engine – not aftermarket swaps. If you’re hunting for a water pump gasket or a clutch release bearing, the part number here matches the original Bantam spec. For cooling system repairs, the factory group sheet shows the coolant flow path components. No need to measure bolt holes – the OEM number guarantees fit. And because this is a parts catalog, not a service manual, you get the reference for ordering genuine replacements without the repair steps. Pair it with a service manual from the same source for the torque specs.

Transmission, Transfer Case, Drive Shafts – Sections 3, 4, 5

Transmission parts live in section 3, the transfer case in section 4, drive shafts in section 5. These are the sections you’ll turn to when the carrier starts making noise and you need to identify the internal parts. The catalog lists exploded-view callouts with corresponding part numbers. For example, the auxiliary transmission uses a specific shift fork – the part number is listed under section 4 with the exact description. Always cross-check your existing part’s stamping with the catalog number. The Automotive Industry Overview on Wikipedia gives a general idea of how driveline components are standardized, but only the factory catalog gives you the Koehring-specific numbers.

Axle Suspension, Axles, Wheels, Brakes, Steering – Sections 6, 7, 8, 9, 10

Suspension and axle parts are in sections 6 through 10. The catalog covers the front and rear axles, wheel hubs and drums, air brakes, and steering. If you’re rebuilding a steering box on a 424, the steering section (10) lists the sector shaft, bearings, and seals. Brake sections show the air brake components. One common mistake: ordering the wrong brake chamber because the aftermarket catalog only lists by model year, not by serial number. The factory manual forces you to use the serial number – that’s on page 1. Page 2 has the ordering instructions: always give the group number, part number, and quantity. Do not write “pairs” – specify piece count. That’s the factory method, and it saves return shipping.

Cab, Electrical – Sections 11 and 12

Cab parts (section 11) and electrical (section 12) wrap up the catalog. Electrical parts include switches, wiring harnesses, and lighting. The cab section has glass, door hardware, and trim pieces. For a complete restoration, you need these part numbers. The electrical section doesn’t have wiring diagrams – that’s a service manual function – but it lists every connector and wire terminal by part number. If you’re modifying or replacing the electrical system, start with this list to find the original components, then source modern equivalents if needed.

Does This Parts Catalog Include Torque Specs?

No. This is a parts catalog, not a service manual. It gives you part numbers and quantities, not torque values or assembly steps. If you need bolt torque for the transmission or suspension, you’ll want the factory service manual for the 424. The parts catalog is your companion for ordering the correct hardware. When you’re chasing a loose bolt, the part number from this catalog will get you the genuine Koehring fastener. Then you can torque it to the service manual spec. That combination is what keeps the carrier safe on the job site.

3 Reasons to Choose OEM Documentation Over Aftermarket

First, the part numbers are verified against the original Bantam drawings. Aftermarket catalogs often transpose digits or use superseded numbers. Second, the group index system means you don’t guess which section covers the hydraulic outriggers (section 1A). Third, the warranty statement on page 1 and ordering instructions on page 2 are the same ones the distributor used. No third-party interpretation. The factory manual is the standard.

FAQ – Common Questions About the Koehring 424 Parts Catalog

Does the catalog cover the engine internal parts?

Yes, section 2 includes engine, clutch, cooling, and exhaust components. But it’s a parts list, not a repair guide. You get part numbers for pistons, rings, gaskets, etc., with group numbers to help order correctly.

How do I find the right part for my serial number?

Page 1 tells you the serial number location. Page 2 says to always give serial number and model when ordering. Use the group index to locate the section, then match the part number.

Is this the same as a service manual?

No.

What if I need a part listed as an assembly?

Page 2 says if an assembly is not listed as such, list the individual parts and request them shipped as an assembly. The catalog helps you identify those individual parts from the exploded views.
