Genie GTH-644, GTH-842, GTH-844 2017 Parts Catalog

You are pulling a part number for a boom cylinder seal kit and the aftermarket website gives you three different options, none of which match what you have on the bench. That is the difference between guessing and having the actual Genie GTH-644, GTH-842, GTH-844 2017 Parts Catalog open on your tablet. This is a 284-page, factory-issued document printed in July 2017, Part No. 97486, Rev B27. It covers the serial number ranges that matter: GTH-644 from GTH0606A-8418 to GTH0610A-14000 and from GTH0606B-6271 to GTH0610B-14000, GTH-842 from GTH0806A-8418 to GTH0810A-14000, GTH-844 from GTH0806A-8418 to GTH0810A-14000 with their corresponding B-suffix ranges. If your machine falls inside those numbers, this is the only parts catalog you should trust.

Serial Number Range and Model Identification

Every parts manual is only as good as the serial number breakdown it provides. Page 1 of this catalog lists the exact VIN ranges for each model – GTH-644, GTH-842, and GTH-844 – split by A and B suffix codes. You have to read your serial number correctly before you order anything. The manual shows a factory serial label located inside the chassis upright at the cab side, and the number is also stamped on the chassis. On page 3, there is a full explanation of how to decode the serial number: model year, facility code, and sequence number. Ignore that step and you will order a steering cylinder that does not fit a later production machine.

Parts Figures: Exploded Views and Part Numbers

The Table of Contents in this catalog is interactive – each figure listing is a live link in the PDF. You click on the figure you need, and it jumps you directly to that exploded view. Every bolt, seal, hose, and bracket is called out with a reference number and a corresponding part number in the parts list. This is not a generic drawing. Genie designed these figures specifically for the GTH-644, GTH-842, and GTH-844 telehandlers. If you need a replacement for the boom wear pads or the outrigger cylinder, you find the figure, locate the callout, and order the exact Genie OEM part. No cross-referencing dubious aftermarket catalogs.

How to Order Parts the Right Way

Ordering parts from a factory catalog means you have the correct part number before you call the dealer. The manual includes a section titled “How to Order Parts” on page 8. It tells you what information you need: model, serial number, part number, quantity, and shipping instructions. It also lists a Parts Stocking List on page 7 that identifies commonly replaced items. Using this list, you can keep high-wear components on your shelf and avoid machine downtime waiting for a part.

A quick note about related manuals. If you need the service procedures to go with these part numbers, check out the Genie GTH-644 GTH-842 GTH-844 2006 Parts Catalog for older machines, or the Genie GTH Series 2007 Service Manual for repair instructions. For a broader coverage of multiple models including the GTH-636 and GTH-1048, the Genie GTH-644, GTH-842, GTH-844, GTH-636, GTH-1048 2007 Service Manual is a solid companion.

OEM vs Aftermarket Documentation

An aftermarket parts list will give you a generic part number that may or may not match the factory spec. This catalog is Genie’s own publication, printed by Terex Corporation. The copyright is 2011, revision B27 dated July 2017. The accuracy statement on page 2 says Genie has “endeavored to deliver the highest degree of accuracy possible” and that product specifications are subject to change. That means if a part was revised during production, this catalog reflects the latest revision. Aftermarket reprints never carry that level of traceability. For a broader context on why factory documentation matters, the Automotive Industry Overview includes standards for component identification. The same principle applies to heavy equipment – you rely on the manufacturer’s own data.

Does This Manual Cover Your Genie GTH-844?

If your GTH-844 has a serial number between GTH0806A-8418 and GTH0810A-14000, or the B-suffix range GTH0806B-6956 to GTH0810B-14000, then yes – this catalog covers it. The manual also covers the GTH-644 and GTH-842 within the ranges printed on page 1. There is no guesswork. You look at your serial number plate, compare it to the list, and you know immediately if you are holding the right document. The catalog even includes a sample serial label image so you can verify you are reading the number correctly.

284 Pages of Factory Data

284 pages might sound like a lot for a parts catalog, but that is what it takes to document every fastener, seal, hydraulic fitting, and structural component for three telehandler models across multiple production years. The PDF bookmarks are organized by figure number, so you can jump to any assembly in seconds. If you have a printed copy, the manual tells you on page 4 that you can keep it updated by accessing new figures from the Genie website. For the most current data, visit the Genie Parts Lookup System online. But for a static, offline reference that works on any device, this PDF is your best bet.

Does this parts catalog include torque specifications?

No, this is a parts manual – it lists part numbers and exploded views only. Torque specs are in a separate service manual.

How do I identify the correct part for my GTH-644 if the serial number is missing?

That is a common problem, and the manual does not directly solve it. However, you can use the figures to visually match the component you removed. The catalog includes multiple views of the same assembly in some cases (e.g., boom sections, steer axle). You compare the shape, number of bolt holes, and hose routing to the drawing. If you can find a date code or casting number on the old part, that can cross-reference to a figure callout. Many technicians also use the Parts Stocking List (page 7) to identify high-wear items that are visually distinct. When all else fails, contact Genie customer service with your machine’s VIN – the factory has records that tie VINs to production changes.

You have a Genie telehandler sitting in the yard waiting for a hydraulic hose or a steering knuckle. Without the Genie GTH-644, GTH-842, GTH-844 2017 Parts Catalog, you are ordering parts blind. Get the factory listing, find the correct figure, and order the part number that Genie stamped on the drawing. Access the Factory Manual from AutoRepairManuals and keep it on your shop tablet or printed in a binder.
