GEHL 5450, 5510, 5575, 5750, 5950 Parts Catalog

If you have ever ordered a part for a GEHL mixer feeder and gotten the wrong one, you know the pain. The machine sits. The customer waits. You eat the shipping. That happens when you rely on aftermarket cross-reference lists or memory. A factory GEHL 5450, 5510, 5575, 5750, 5950 Parts Catalog is the only way to get the exact part number, the right grade fastener, and the correct torque specification for every bolt on these four-auger machines. I have been turning wrenches since 1996 and I will not touch a rebuild on a 5750 without this book open on the bench.

What This Parts Catalog Actually Covers

This is a parts manual for the 5450, 5510, 5575, 5750, and 5950 4-auger mixer feeders. It lists every serviceable component from the discharge gate all the way back to the driveline. The table of contents points you to an Alphabetical Index and a Numerical Index, so you can find a part either by name or by the number you already have. Page 26 holds the torque specifications for standard attaching hardware – not a generic chart, but the values GEHL expects for Grade 5 cap screws and hex nuts used on these feeders. Do not guess. Use the book.

Torque Specifications: Inside Back Cover

The inside back cover of this catalog lists standard torque values for cap screws, flange lock nuts, and other hardware. Those numbers are not suggestions. A bolt that is 10 ft-lb under can loosen; one that is 10 over can snap. The catalog also marks specific torque requirements with a hexagon symbol on the exploded views. If you see a number inside a hexagon next to a reference number, that is the required torque in foot-pounds – obey it. I have seen guys strip the chain case cover on a 5510 because they used a generic torque chart from the internet. Do not be that guy.

Reading the Exploded Views and Reference Numbers

Each assembly is drawn with exploded views and reference numbers. A teardrop symbol means a wet product like oil or grease is applied at that point – the number inside the teardrop tells you which lubricant from the list. Reference numbers without a part number are shown for reference only and are not sold separately. The indent/dot system groups subassembly parts under the main assembly. If you order the main assembly, all indented parts come with it. This matters when you are trying to buy just a bearing versus the whole roller assembly. Know the difference before you call the dealer.

Alphabetical and Numerical Indexes

Two indexes are included. The Alphabetical Index lets you look up a part by name – “auger flighting,” “chain,” “sprocket.” The Numerical Index lists every part number in ascending order and tells you which page to find it on. If you have an old part number from a previous repair, start with the Numerical Index. If you are new to the machine, use the Alphabetical Index. Both are cross-referenced to the same part numbers and assemblies. No hunting through 72 pages manually.

That is the kind of organization that saves a Saturday afternoon. Especially when the serial number tag on your 5575 is worn and you need to verify the correct revision of a hydraulic fitting. The introduction page explains where to find the model and serial number – left side of the main frame, facing rearward. Right and left are determined from behind the feeder looking forward. Memorize that orientation before you start calling out “left side” on the phone.

Who Needs This 72-Page Document?

You need this catalog if you own one of these five models and plan to maintain it yourself. You also need it if you work in a shop that services GEHL mixers. The parts catalog does not contain repair procedures – that is what the service manual is for – but you cannot order a single bolt without the correct part number from this book. Even if you have a GEHL 5450 5510 5575 5750 5950 Parts Catalog on your tablet, the hard copy or PDF is faster on the bench. Pair it with the GEHL 5000 Series Mixer Feeder Installation Manual for setup and the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog if your shop also handles skid loaders. Every manual from the same source keeps your parts data consistent.

One more thing – do not trust third-party reprints of these catalogs. The OEM version from AutoRepairManuals is the only one with the exact page numbers, torque specs, and part callouts that GEHL published. Aftermarket copies often scan poorly, blurring the hexagon torque symbols or dropping a digit in the part number. That is a leak waiting to happen. Stick with the factory file.

Why OEM Part Numbers Beat Aftermarket Cross-References

Cross-reference websites and aftermarket catalogs list parts that “fit” multiple models. That might work for a fuel filter, but not for a drive chain or auger flighting. The 5450 and the 5950 share some hardware, but the discharge gate assembly is different. If you order an aftermarket number that fits both, you get a compromise part designed to work – poorly – in either application. The GEHL part numbers in this catalog are exact. You order the auger flighting for a 5750, you get the flighting designed for that specific auger diameter and pitch. No shimming, no grinding, no returns.

For background on how diesel engines and power systems work in these machines, check out this Wikipedia article on diesel engines. For a deeper dive into the specific engine controls used in GEHL equipment, see this Wikipedia article on diesel engines. Both links provide general knowledge, but the parts catalog gives you the exact nuts and bolts.

How do I find the right part number for a bolt on my 5510 auger?

Start with the Numerical Index. Find the part number from your existing bolt or look up “auger” in the Alphabetical Index. Cross-check the exploded view drawing for the correct reference number. The bolt grade and torque are listed on the inside back cover.

Does this catalog include torque specs for the gearbox?

Yes. Standard torque values for all hardware are on the inside back cover. Specific gearbox bolts are called out with a hexagon symbol and foot-pound value on their respective exploded view pages.

The bottom line: if you are rebuilding a GEHL 5450, 5510, 5575, 5750, or 5950, you need the factory numbers. Do not rely on memory or aftermarket charts. Access the Factory Manual from AutoRepairManuals and keep it within arm’s reach of the toolbox.
