Genie GTH-644, GTH-842, GTH-844 2006 Parts Catalog

You ever ordered a part based on a generic aftermarket list, only to find out it’s the wrong seal, wrong hose length, or wrong cylinder? That’s time and money down the drain. This Genie GTH-644, GTH-842, GTH-844 2006 Parts Catalog is the factory document—179 pages of figure numbers, revision letters, and part numbers that match what Genie shipped. You don’t need to guess part numbers. If you maintain any of these rough terrain forklifts, this is the reference you need on the bench, not some third-party compilation.

Genie GTH-644, GTH-842, GTH-844 2006 Parts Catalog: What You Get

Three models are covered across their serial number ranges. For the GTH-644, serial numbers from GTH0606A-8418 and GTH0606B-6271. For the GTH-842, from GTH0806A-8418 and GTH0806B-6958. For the GTH-844, from GTH0806A-8418 and GTH0806B-6956. The document is dated January 2006, Part No. 97486 Rev A. Each figure has a revision letter, so if Genie updates a component, you can track the change. The table of contents lists over 70 figure groups from decals to accessories.

Fuel Tank Assembly and Engine Components: What’s Covered

Section 200 includes the Fuel Tank Assembly for all models (figure 203.1). Section 300 covers Engine Components for the JD-4045 Tier II engine: engine and pump assembly, exhaust, air cleaner, starter relay and sender. If you need the part number for a fuel line or filter, this is where you find it. The catalog also includes the Engine Enclosure Assembly (208.1) and the Power Train Assembly (201.1). For the fuel circuit, section 617 provides a dedicated diagram for the JD-4045 Tier II, showing hose routing and connection points. That’s the kind of detail aftermarket catalogs skip.

3 Systems That Will Bite You Without Proper Part Numbers

First: the hydraulic circuits. Section 600 diagrams every circuit—pump, lift-tilt, boom, 4-way controller, steering, sway, parking brake, differential lock, oil cooler, and fuel circuit. Without the exact hose part number, you’ll be fighting leaks. Second: the boom components. Section 500 shows boom assembly in ten views, with all pins, cylinders, and wear pads. Third: the cab components—operator’s compartment, foot brake, accelerator, instrument panel, 4-way controller. One wrong switch part and the machine won’t start. If you order a tilt cylinder without checking the figure, you might get one for the GTH-844 when you have a GTH-642. The part numbers differ. The same goes for the motion valves—figure 707.1 for base lift cylinder, 708.1 for head tilt, 709.1 for boom. Each has its own part number. This catalog eliminates that confusion.

Does This Catalog Include Hydraulic Circuit Diagrams?

Yes, and they are model-specific. For example, circuit Lift-Tilt for the GTH-844 (figure 602.1) is separate from the GTH-842 (603.1) and GTH-644 (604.1). The boom circuits differ too: GTH-644 and GTH-844 share figure 605.1, while GTH-644 has its own 606.1. Each diagram shows hose routes, fitting part numbers, and port locations. You also get circuit pressure checks (613.1) with test point callouts. That means you can cross-reference the part number for any fitting before you order.

Decals and Serial Number Location: Small Details That Matter

Section 100 covers decals—two views for all models. If a decal is missing or faded, you need the correct part number for compliance and safety. The manual shows how to read your serial number (page iii) and where the serial label is located: inside the chassis upright at the cab side. Stamped serial number on chassis.

Use the serial number range to confirm fit.

How to Order Parts—Factory Procedure

A factory order form is included in the catalog along with instructions. You need the figure number, revision letter, item number, part number, and quantity. Each figure has a table listing the parts. For example, the power train assembly figure 201.1 lists the engine, mounts, belts. Don’t rely on memory—use this catalog to cross-reference before you call your dealer.

Does this manual cover the fuel system?

Yes, section 200 includes the Fuel Tank Assembly, and section 617 covers the fuel circuit for the JD-4045 Tier II engine.

What serial numbers are covered for the GTH-842?

From GTH0806A-8418 and GTH0806B-6958. Verify your machine’s serial plate against these ranges.

Are part numbers for the hydraulic hoses included?

Yes. Section 600 provides hydraulic circuits with part numbers for hoses, fittings, and assemblies. Each model’s lift-tilt and boom circuits are shown separately.

How can I tell if a figure has been updated?

Each figure in the catalog has a revision letter, such as ‘Rev A’ or ‘Rev B’. When Genie updates a component, they release a new figure with an updated letter. You can compare the revision letter in your printed manual against the latest figures available on the Genie website. If your figure is Rev A and the latest is Rev B, you need to access the new figure to get the current part numbers. This is especially important for safety-critical components like decals, hydraulic hoses, and engine parts. The catalog itself (Part No. 97486 Rev A) was published January 2006, but individual figures may have been revised later.
