Koehring T-744 Parts Catalog

If you have ever chased a wrong part number on a T-744 because some aftermarket list threw a generic bolt size at you, you know the drill: order it, wait, pull the old one, and find it does not fit. That is billable time the shop never gets back. This is a 147-page factory-issued Koehring T-744 Parts Catalog that gives you the exact reference numbers and exploded diagrams Koehring printed when these machines left Waverly, Iowa. No cross-reference guessing. No third-party reprints. Original OEM print.

The catalog is organized by a group index on page 2: MAIN FRAME, COUNTERWEIGHT, FUEL TANK, ROTEK LUBRICATOR, ENGINES, ENGINE CONTROLS, CLUTCH, GEAR REDUCTION UNIT, HYDRAULIC SYSTEM, SWING SPEED REDUCER, CAB, SEAT, CONTROLS, ELECTRICAL SYSTEM, ACCESSORIES, TELESCOPING BOOM, BOOM ATTACHMENTS, STABILIZERS, HYDRAULIC REMOTE CONTROL, and general reference info. Each section has its own table with reference numbers, part numbers, descriptions, and quantities. You read the part number right off the page, order it, and it lands. No wasted bench time.

Main Frame, Counterweight, and Fuel Tank Parts

Look up the main frame assembly and you get the full breakdown — bolts, lockwashers, bushings, and the 4000- or 5000-pound counterweight options. The Fuel tank is listed as a 60-gallon assembly with cap vent and sending unit. Part numbers like F66001 (main frame) and F54300 (cover) are pulled from the original Koehring engineering drawings. You will also see the turntable bearing and mounting base hardware. Everything is there to rebuild the bottom half of the machine without calling a dealer.

Engine and Clutch Specifications – What’s in the Catalog?

The Engine group covers the power unit and its controls — clutch, gear reduction unit, and all attaching hardware. You get the part numbers for the bolts, washers, and specialty items like the bronze bushing and self-aligning bushing listed on page 1. The catalog also references the battery brackets for GM, AC, and Cummins engines. If you are swapping an engine or rebuilding the clutch pack, you trace every component back to the factory bill of materials.

Hydraulic System Component Breakdown

Hydraulic system section goes through the pump, valves, lines, and fittings. No service sequence here — this is a parts catalog, so you get the component numbers and the exact fastener specs. Need a capscrew for the hydraulic manifold? The group tells you the grade (Gr. 8), thread size, and length. That is the kind of detail that keeps a tech from snapping a bolt inside an aluminum casting. Koehring T-S44, 644 1974 Parts Catalog – Factory OEM Parts Reference covers earlier models with similar hydraulic architecture.

Electrical System: Wiring and Component Identification

Electrical system group includes the cab wiring, switches, and senders. The Electrical section references the sending unit with gasket, the battery bracket assemblies, and the capscrews for mounting. If you are chasing a short or replacing a harness, the part numbers for connectors and relays are listed. The manual also notes the serial number requirement — when ordering, specify the Bantam serial number, part number, and name of part. That is a hard rule from page 1. Ignore it and you might get the wrong revision.

3 Reasons to Use OEM Parts Documentation

First, aftermarket parts lists often merge different production years. This catalog captures the T-744 as built from the early 1970s through July 1983. Second, the exploded views show the stacking order — you see which washer goes where before you start disassembly. Third, the Parts Catalog gives you the correct bolt grade and torque specification references. Yes, torque values are in the service manual, but the hardware specs here let you look up the right fastener before you apply a wrench. Koehring S-155 1977 Parts Catalog – Factory OEM Parts Reference follows the same format for the S-155 line.

Get the Right Part Numbers for Your T-744

If you work on older construction equipment, you know the pain: a dealer says the part is NLA, and you spend an hour cross-referencing. With this catalog, you can search for the exact Koehring part number, then source it from aftermarket suppliers with confidence. The 147 pages cover every major group — from the ROTEC lubricator to the telescoping boom attachments. You will find the stabilizer group and the hydraulic remote control section. Koehring 366 Hydraulic Hoe Parts Catalog – OEM Factory Specs is another resource for a different chassis. For a broader look at construction equipment, check the Automotive Industry Overview or Automotive Industry Overview.

Does this catalog include torque specs?

No — it is a parts catalog, not a service manual. Torque values are in the factory service manual.

How do I locate a part number for the fuel tank?

Go to the group index on page 2, find “MAIN FRAME, COUNTERWEIGHT, FUEL TANK, ROTEK LUBRICATOR.” Inside that section look for the fuel tank assembly (part F66099). The exploded view shows the tank, cap vent, sending unit, bracket, and all mounting hardware with quantities. Each part has a reference number that ties to the Koehring original drawing. If you still have the old part, compare the number printed on it against the catalog. That is the fastest way.

Lots of shops I have worked with keep a copy of the original parts catalog on the bench. When a generator pulls off the bottom of a T-744, you need the right part number, not a guess. Access the Factory Manual and get the exact specs Koehring put in the crate.
