GEHL AL-730 Parts Catalog – 290 Pages of Factory Parts Data

If you are wrenching on a GEHL AL-730 Parts Catalog and you order the wrong part because the catalog you have lumps everything together, you are not saving time—you are burning money. I have seen it too many times. A guy grabs a part number from a generic website, gets a box that does not fit, and then the machine sits while he waits for the right one. That is why you need the factory parts catalog, not a reprint or a scanned copy of something somebody guessed at. This one is the real deal: 290 pages, direct from GEHL, with all the serial number breaks that matter.

What the GEHL AL-730 Parts Catalog Actually Contains

Flip to the Table of Contents and you will see it broken down by major assemblies: DECALS, OPERATOR’S STATION, CHASSIS, ENGINE, TRANSFER CASE, TRANSMISSION, AXLES (with two separate sections for S/N 65167 and up vs. thru S/N 65166), and BOOM. Each section has sub-groups like ‘Cab Enclosure – Front Glass (S/N 65168 and Up)’ and ‘Cab Enclosure – Front Glass’ for the earlier machines. That split is critical.

Factory OEM print.

Serial Number Splits – Why They Matter

On page 2 of the manual, they explain how to read the serial number plate. The sequence tells you year, month, engine, boom type, and unit number. Without this, you cannot match the correct revision of parts. The manual lists components by serial number ranges throughout. For example, the Transmission section has ‘Fwd. Low/High Shaft & Gears Group Thru S/N 65142’ and another for S/N 65143 and Up. That’s the level of detail you need.

Parts Identification – Exploded Views and Hardware Torques

Each group has an exploded illustration with callouts. The parts list below includes part numbers, descriptions, and quantities. Standard attaching hardware torque values are provided on the inside back cover. The manual specifies that all capscrews are Grade 5 unless noted. If you are rebuilding an axle or transmission, you need those torque numbers. For related loaders, check the GEHL AL-730 Parts Catalog and GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog.

Does This Parts Catalog Cover the Engine and Transmission?

Yes. Under ENGINE you get External Engine Components, Radiator Group, Air Cleaner Group, Engine Muffler Group. Under TRANSMISSION you get the full breakdown: Converter Housing, Case Group, Torque Converter, Charging Pump, Pump Drive, all the shaft and gear groups, Control Valve. That is 50-plus pages of transmission detail alone. The TRANSFER CASE has its own section with assembly groups. For understanding diesel engine basics, see this Wikipedia article on diesel engines.

3 Reasons to Use the OEM Parts Catalog Over Aftermarket

First, the factory document includes the exact part numbers GEHL uses. Aftermarket catalogs often substitute superseded numbers incorrectly. Second, the exploded diagrams show fastener location and orientation—critical when you are trying to figure out which bolt goes where. Third, the filter reference on page 3 lists part numbers for engine oil, fuel, air, transmission, and hydraulic filters with serial number notes. You do not get that from a generic cross-reference. Also see the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs for similar models.

The manual’s engine section covers the external components, but if you want to learn more about diesel operation, this Wikipedia article on diesel engines provides background.

Frequently Asked Questions

Can I use this parts catalog for a different GEHL model?

No. This is specific to the AL-730 Agri-Loader.

What if I need a part that is not listed in the exploded view?

Check the ‘List of Abbreviations’ and ‘Standard Hardware’ section. Some common fasteners are listed indented under the parent part but may not be illustrated. If the part is not shown, refer to the hardware table or contact a dealer with your serial number. The manual provides a filter reference and torque spec inside back cover, but special-order items may require additional research. Always verify with the serial number.
