GEHL 1309, 1312, 1315, 1322 Parts Catalog

I’ve seen guys try to rebuild a spreader using a photocopied aftermarket catalog. Part numbers don’t match, illustrations are blurry, and the torque values? Made up. That’s money down the drain and a machine that’s never right. This **GEHL 1309, 1312, 1315, 1322 Parts Catalog** is the OEM factory print — 56 pages of the exact exploded views and part numbers GEHL used on the line. If you’re ordering parts for a Scavenger manure spreader, this is the only source I trust.

Every section is organized by subassembly. You get decal locations, auger drive breakdowns, expeller and discharge gate details, hydraulics, and full axle groups. The brake section for the 1322 model is on pages 26-27 — includes both the axle with brakes and the separate brake hydraulics on pages 28-29. That level of detail keeps you from ordering the wrong caliper or line. I’ve torqued enough bolts to know that the standard hardware torque table on the inside back cover is worth the price of the manual alone.

Brake System Breakdown for the 1322

If you’re working on a 1322 with brakes, you need pages 26-29. The catalog separates the tandem axle assembly with brakes from the hydraulic circuit. That means you can order individual wheel seals, line fittings, or the master cylinder without guessing. Aftermarket catalogs lump everything together and you end up with a box of wrong parts. This manual gives you the part numbers for the brake hydraulics section — reservoir, lines, wheel cylinders — all laid out in exploded view. Save yourself the return shipping.

What Does the Hydraulics Section Cover?

Pages 12-15 cover the full hydraulic system. That includes the pump, control valve, cylinder ports, and hoses. Each component is called out with a reference number tied to the parts list. You get the exact GEHL part number, description, and quantity. No abbreviations that leave you guessing — the catalog even includes a full abbreviation table on page 2. Need a flanged cap screw or a specific O-ring? It’s there. I’ve used this section to rebuild a control valve on a 1315 in less than two hours because I had the right parts on hand.

56 Pages of OEM Parts Catalog Data

Fifty-six pages might not sound like much, but every page is loaded. The catalog covers models 1309, 1312, 1315, and 1322 — single and tandem axle versions. Page 18 is the 1309 single axle; page 19 is the 1312 single; pages 20-21 are the 1312 tandem; pages 22-23 the 1315 tandem; and pages 24-25 the 1322 tandem. Then the brake variants. Plus component breakdowns for augers, hydraulic cylinders, splash guards, hitchjacks, and PTO drives (540 RPM for 1309/1312/1315, 1000 RPM for 1322). Options like the hydraulic lid kit and safety chains are included. This is not a generic collection — it’s the actual factory file with GEHL form number 907503 Revision B.

Get the Right Torque Specs from the Back Cover

The inside back cover has standard hardware torque values. Not a separate page you have to hunt for. When you’re reassembling the auger drive or the expeller, those numbers matter. I’ve seen stripped threads from torquing a Grade 5 bolt to Grade 8 spec. This table tells you exactly what to apply for each fastener grade and size. Don’t rely on a generic chart from the internet. Use the one GEHL printed for this machine.

Auger Drive: Matching Parts to Your Model

Pages 6-7 break down the auger drive assembly for all four models. The parts vary between the 1309 and the 1322 because of different conveyor widths. The catalog shows each shaft, sprocket, bearing, and chain with model-specific callouts. If you’re retrofitting a newer drive on an older spreader, you can cross-reference the part numbers directly. I’ve done it — saved a customer from buying a whole new assembly when all they needed was a sprocket and a bearing. The exploded view is clear enough that a first-time DIYer can identify the parts, but detailed enough for a pro to order from.

GEHL 1309-1322: Why the Original Factory Manual Matters

I’ve been turning wrenches for 28 years. Aftermarket manuals are a gamble. They reuse old drawings, skip pages, and sometimes substitute wrong hardware grades. This catalog is the actual OEM file — printed from the same plates GEHL used. Every part number is traceable to the factory. If you need a replacement wheel set, the tire size info is called out, but GEHL won’t sell you tires — you buy those locally. That’s in the note on page 2. That kind of transparency is what you get with an authentic manual. Don’t waste time on copies. Get the real one.

Does this manual include torque specs for the brake lines?

No. The inside back cover has standard hardware torque values for bolts and nuts. Brake line fittings are not listed separately; use the hydraulic fitting data on page 52.

I have a 1315 tandem axle without brakes. Which pages cover my axle?

Pages 22-23. The 1315 tandem axle section includes the hub, spindle, bearings, and seals. If you later add brakes, you’ll need the 1322 brake pages. The catalog notes that the 1315 and 1322 share some axle components, but always verify by serial number. The model and serial plate is on the front left corner of the tank. Write it down before you order anything. I’ve seen guys order the wrong spindle because they guessed the year. Don’t guess — use the plate. Also note that the 1315 tandem uses different wheel studs than the single-axle 1309. Page 22 shows the correct part numbers. Cross-check with the numerical index starting on page 46 if you need to find a specific fastener. The hydraulic fitting data on page 52 will help you match JIC and O-ring boss fittings. That page alone has saved me a return trip to the parts store more than once.

Whether you’re rebuilding a spreader from the frame up or just replacing a cracked auger liner, having the factory part numbers in front of you cuts the guesswork out. Access the Factory Manual and keep a copy at the bench — you’ll use it every time you order a seal or a bolt.
