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

If you’ve ever ordered a part for an AL-730 and got the wrong one because you grabbed the serial number off the wrong plate or matched a bolt by eye instead of checking the table, you already know why this catalog exists. I’ve seen it a hundred times in my shop – a guy slaps in a fuel filter that looks right but doesn’t cross-reference the engine serial number break, and then he’s scratching his head when the machine won’t prime. That’s time you don’t get back. This GEHL AL-730 Parts Catalog is the OEM document – 290 pages of factory-printed part numbers, exploded views, and hardware callouts. Nothing generic. Nothing re-typed by some third-party outfit that dropped a decimal point. It’s what you need to order the correct component the first time.

AL-730 Parts Identification – Boom, Axle, Transmission Sections

The catalog splits the machine into logical groups. You’ve got the boom – Inner Boom Front Section for S/N 65165 and up (includes serial numbers 65149, 65155, 65158 – they list them out so you don’t guess). Axle sections are split by serial number break: S/N 65167 and up, and thru S/N 65166. Each group shows the exploded assembly with a callout number tied to the parts list. Transmission gets its own deep dive: external driveshafts, converter housing, torque converter, charging pump, fwd low/high shaft (two serial number breaks, S/N 65142 and 65143 up), rev/1st shaft, 2nd shaft, input, output – all broken down. If you’re pulling a transmission on an AL-730, you need to see which shaft group applies to your unit number. The catalog tells you.

What’s Inside the Engine and Transfer Case Sections?

Engine section covers external components, radiator groups (again split by S/N 65178 and up including 65169, and thru S/N 65177 except 65169), air cleaner groups, muffler. Transfer case has external components and the assembly in two parts – part 1 and part 2. That’s important because the transfer case on these Agri-Loaders takes a beating, and if you’re ordering a seal or bearing, you need the exploded view from the correct part. The filter reference on page 3 of the manual lists exact part numbers: engine oil filter L99420 (thru S/N 65177) and 102174 (S/N 65178 up), fuel filters, air filter L99453, safety element L99967, transmission oil L99440, hydraulic L99459. Write those down. Tape them to the machine. You’ll thank me later.

Decals and Operator’s Station: Why Placement Matters

Decals are part of the machine. You skip the decal section and you miss the warning labels, the control markings, the load charts – that’s a liability. This catalog has decal locations for operator’s station, left side, right side, tractor and boom. Operator’s station section covers cab enclosures (front, top, left, rear glass – split by S/N 65168 and up vs. thru S/N 65167), dash/tilt plastic housing, heater A/C groups, A/C condenser, hoses compressor dryer, steering column, console tilt, brake pedal, throttle pedal, right panel plastic and seat group. Every part number is there. If the heater blower motor dies and you need a replacement, it’s in that group. No calling the dealer and hoping they guess right.

Get the Right Part Number the First Time

The serial number breakdown on page 2 of the manual is critical. GEHL stamped the serial number on a plate inside the operator’s station and also on top front of the frame. The breakdown is: Boom Type – Unit Number – Engine – Year (T=02, U=03, V=04 etc.) – Month – Model. For example, 7 3 0 L J V 0 3 6 5 1 7 2. You read that left to right. If you ignore that and just order by machine model, you’ll get wrong parts. I’ve had guys bring me a starter that didn’t fit because they didn’t check the year letter. The catalog also includes a table of standard washers and nuts on page 2 – they list part numbers for common hardware (e.g., 1/4-20 NIN L520003, 3/8-16 SFN L50061). Grease fittings and attaching hardware are listed indented under the component they fasten. Standard capscrews are Grade 5 unless noted. Torque values for standard hardware are on the inside back cover. That’s a spec I’ve used more times than I can count.

7 Major Machine Systems Covered in This Parts Catalog

Look at the table of contents: Decals, Operator’s Station, Chassis (rear access door, engine transmission cover, battery tray, hydraulic tank, fuel tank), Engine, Transfer Case, Transmission, Axles (two full sections for both serial number breaks), and Boom. That’s seven major systems. Inside each are subgroups with exploded views that show every nut, bolt, seal, and hose. If you’re rebuilding a front axle on a machine thru S/N 65166, you’ve got limited slip housing, swivel housing, steer cylinder, gear and pinion set, differential, double joint shaft, brakes, wheel hub, planetary drive – all separate sections. The catalog doesn’t leave anything out. It’s 290 pages of OEM data. this Wikipedia article on diesel engines explains how those engines work, but for parts identification, you need the factory catalog.

FAQ – Common Questions About the GEHL AL-730 Parts Catalog

Does this catalog include torque specs for assembly?

It lists standard attaching hardware torque values on the inside back cover, but not specific engine or transmission internal torque values. That belongs in the service manual.

Can I use this to rebuild the transmission?

Yes – you’ll get every part number for shafts, gears, seals, and bearings. You’ll need a separate service manual for clearances and procedures, but this catalog is mandatory for ordering the right parts.

How do I find the correct part for my machine’s serial number?

Locate the serial number on the frame near the operator’s station. Use the explanation on page 2 to decode the year and month. Then match your S/N range in each section heading – the catalog clearly marks sections for specific serial number breaks.

Is this a reprint or an original OEM document?

This is a direct scan of the original GEHL factory parts manual, Form No. 908473 Revision B. No alterations, no aftermarket editing. The filter reference, decal locations, and part numbers are exactly what the dealership uses. The catalog is 290 pages and includes the list of abbreviations (AN, ASR, ASY, BHB, etc.) from the original print. I trust OEM documentation because I’ve been burned by aftermarket diagrams that swap left and right. Access the Factory Manual and keep a copy in the toolbox.
