Koehring Bantam C-744, 744 1975 Parts Catalog

I’ve been turning wrenches for 28 years, ASE Master Certified, running a six-bay shop here in San Antonio. If you’re trying to keep a Koehring Bantam C-744, 744 1975 Parts Catalog machine alive without the factory parts breakdown, you’re wasting time hunting for part numbers that don’t match. This is the real deal—129 pages of exploded views and OEM part numbers, not some aftermarket copy that swaps a 5/16 bolt for a metric one and leaves you with a stripped bracket at 6 PM on a Friday.

Main Frame, Counterweight, Fuel Tank – Group 1 Breakdown

Group index starts with the main frame, counterweight, and fuel tank assembly. The catalog gives you the exact Bantam part number for the 4000# counterweight (B43003) and the battery bracket variations for GM, AC, and Cummins engines. You get snap rings, lockwashers, 5/16 UNC nuts, bronze bushings, and the grease fitting. No guessing if a generic bushing will fit—the OEM part number is right there on page 1-1. Replace the fuel tank with confidence because the drawing shows where every bracket and strap goes.

Engines, Engine Controls, Clutch – Group 4 Coverage

Group 4 covers the engines, controls, clutch, and gear reduction unit. If you’re swapping a clutch or rebuilding the gearbox, you need the Bantam-specific parts, not something from a truck supply house. This catalog lists both the GM and Cummins engine brackets separately—F46075 for Cummins, A18288-1 for GM—so you don’t order the wrong one. Automotive Industry Overview standards don’t apply here; it’s Koehring factory engineering all the way.

Hydraulic System – Group 7: What You Need

The hydraulic section (group 7) lists every seal, fitting, and valve Bantam used on the C-744 and 744. One wrong O-ring can turn a boom drift into a safety hazard. With this catalog, you order the exact seal kit from your authorized distributor instead of playing mix-and-match. The group index puts you on the right page fast—page 1 shows the main frame components, but group 7 runs from page 7 onward. No wasted time flipping through generic diagrams.

Electrical System – Group 10 Wiring and Components

Group 10 is the electrical system. It’s not a full wiring schematic—it’s the parts catalog, so you get the factory part numbers for alternators, starters, switches, and harnesses. If your 744 won’t crank, grab the Bantam part number for the starter solenoid from this group and order the genuine piece. Aftermarket electrical parts on construction equipment are a gamble; the voltage drop alone can eat your ground. Use the OEM numbers from this manual.

Telescoping Boom – Group 12 and Attachments

Group 12 covers the telescoping boom. Each section—inner, intermediate, outer—has its own set of wear pads, pins, and hydraulic cylinders. The catalog shows exploded views so you see the order of assembly. Pair that with the boom attachments section (group 13) for the bucket pins and quick-coupler parts. You’ll know exactly what to order for a full boom rebuild.

Why OEM Documentation Beats Aftermarket Copies

Aftermarket parts catalogs renumber parts, delete notes from the factory, and sometimes leave out entire groups. This is the 1975 original, printed by Koehring Bantam. Every part number starts with the OEM prefix (F-series, A-series). You can order direct from a distributor without cross-referencing. The group index on page 2 takes you to the exact section—main frame, engines, hydraulic, swing speed reducer, cab, electrical, accessories, telescoping boom, boom attachments, crawler, crawler hydraulics. 129 pages of verified data.

Does this catalog include torque specifications for bolts?

No. This is a parts catalog, not a service manual. Torque specs are in the separate service repair manual.

Can I use this for the 744 model without a serial number?

Yes, the catalog covers both C-744 and 744. But each page header reminds you to specify your Bantam serial number when ordering parts—that’s critical for production changes.

What kind of diagrams are in the electrical system section?

Group 10 has exploded-view part diagrams showing alternators, starters, switches, and harness routing. It does not contain wiring schematics; those are in the electrical service manual.

Is this a reprint or an original OEM catalog?

This is a high-resolution scan of the original 1975 factory catalog printed by Koehring Bantam. It’s not a reprint or third-party compilation. You get the same part numbers, notes, and group index that the dealer used. The document includes the official catalog number C-744-9J and “Printed in U.S.A.” on every page. If you order from an authorized Bantam distributor and provide these numbers, they will honor them. No hacks, no aftermarket shortcuts—just factory spec data.

Access the Factory Manual now and stop guessing what part goes where. Your time on the bench is worth more than hunting for numbers that don’t exist.
