GEHL 309 Parts Catalog

You need a part for your GEHL 309 Scavenger II, so you pull up some aftermarket junk that lists a generic “bearing” and hopes you match it by eye. Then the part doesn’t fit, the machine sits, and you’re out hours. That’s the pain. The factory GEHL 309 Parts Catalog kills that guesswork. 80 pages of OEM exploded views, part numbers with descriptions, and standard hardware torque specs on the inside back cover. No third-party reprints, no vague drawings. Every fastener type is called out using the abbreviations table on page 2 – CS for cap screw, FLN for flanged lock nut – so you order exactly what the assembly line used.

What you get is a document built for ordering parts, not for reading on the couch. It starts with decal locations from pages 2-3. Then it dives into the input shaft and bearings on pages 4-5. Every section is split by serial number because GEHL made running changes. Trying to order an auger drive assembly? You need to know if your machine is after 309-SN4324 or before 309-SN4325. The manual lays out those splits clearly – I’ll cover that in a minute.

GEHL 309 Parts Catalog: 80 Pages of Factory Specs

Full table of contents covers all major systems: Input Shaft & Bearings (pages 4-5), Auger Drive with three serial number ranges (pages 6-11), Expeller & Expeller Drive (12-13), Gate, Pan, Auger Slides & Liners (14-15), Hydraulics (16-19), Hitch, Jack & Drive Shields (20-23), Universal PTO Drives from Weasler and Walterscheid for 540 and 1000 RPM (24-33), Axles, Wheels & Hubs with and without brakes (34-47), Components like jacks, augers, and cylinders (48-53), and accessories such as hydraulic brakes, splash guards, safety chains, and transport lighting (54-67). Each page group gives you an exploded isometric drawing with numbered callouts and a corresponding parts list. No need to flip between sections – part number, description, and quantity per assembly are right there.

Which Serial Number Range Does Your Spreader Use?

GEHL’s Scavenger II went through multiple revisions. The manual reflects that. For example, the Auger Drive has three separate sections: after 309-SN4324, before 309-SN4325, and before 309-SN3427. The Hydraulics split after 309-SN4215. The Universal PTO drives change based on whether you’re before or after 309-SN3426. Find your machine’s serial number on the plate located on the front, left corner of the tank, as stated on page 2. Then match it to the correct drawing. Order the wrong part? That’s on you. The manual gives you the data to get it right the first time.

7 Systems Covered in the Exploded Views

The drawings aren’t fluff. Each system is broken into sub-assemblies with clear callouts. Input shaft bearings, expeller drive chains, gate cylinder mounts – the part numbers are printed next to the illustration. For the PTO drives, you get separate sections for Weasler and Walterscheid, 540 and 1000 RPM, with and without shear device. Standard hardware torque values are printed on the inside back cover – Grade 5 cap screw torque, hex nut grades, lock washer specs. That’s the page you’ll dog-ear for reassembly. Do not trust generic torque charts; use the factory values because GEHL built the spreader with those fasteners.

Order the Correct Part Number Every Time

Aftermarket parts catalogs often substitute a common number and hope it works. This manual gives you the exact GEHL part number. For items that are not available as individual parts, the manual marks them with no reference number – they are shown for reference only. The note on page 2 says: “Unless otherwise specified, all Cap Screws or Bolts are Grade 5, cadmium or zinc plated; Hexagon Nuts for Grade 5 Screws or Bolts are Grade B.” That kind of detail prevents you from ordering a weaker bolt that strips out under load. There’s even a numerical index at the back (pages 68-73) so you can search by part number and find which illustration it belongs to.

If you’re working on other GEHL models, check related manuals: the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog covers skid loaders, and the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs handles larger machines. The GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual is another good resource for rollers. All are direct OEM prints, no aftermarket copy.

Understanding how the PTO shaft transmits power from the tractor’s diesel engine matters if you’re replacing the driveline. For background on diesel power fundamentals, refer to this Wikipedia article on diesel engines. For a deeper dive into four-stroke cycle and torque characteristics, see this Wikipedia article on diesel engines. It’s not required reading, but it helps when diagnosing PTO speed issues.

FAQ

Does this manual include torque specs for the fasteners?

Yes, inside back cover.

How do I figure out which section applies to my spreader when there are multiple serial number splits?

Locate the serial number plate on the front left corner of the tank. Write it down. Then go to the Table of Contents and find the system you need – for example, Auger Drive. The TOC lists three serial number ranges: “After 309-SN4324”, “Before 309-SN4325”, and “Before 309-SN3427”. Compare your machine’s serial number to those thresholds. If your machine is, say, SN4300, that falls before SN4324 but after SN3427? Wait, check carefully: if you have SN4300, you are before SN4325 but also after SN4324? Actually SN4300 is less than SN4324, so it would be before SN4324. That means you use the “Before 309-SN4325” section? No, the manual splits at specific breakpoints. Read the exact wording: “After 309-SN4324” means machines with serial number greater than SN4324. If your SN is 4300, you are before that, so you use the “Before 309-SN4325” section (which covers SN up to SN4325). Yes, it’s precise. If your SN is 4350, it falls after SN4324, so use the “After” section. This manual is built for that level of specificity. Don’t guess; verify.

This document is not a repair manual. It’s a parts catalog. You use it to order the correct factory replacement components. Pair it with an OEM service manual if you need disassembly procedures, but for part identification and ordering, this is the definitive source. 80 pages, original factory print, no missing pages. Access the Factory Manual now and stop wasting time with part number lookup sites that give you incorrect cross-references.
