GEHL CA670 Parts Catalog – OEM Factory Parts Manual

If you’re ordering parts for a GEHL CA670 one-row attachment and you guess the part number, you’re wasting time and money. I’ve seen too many guys bolt on a wear shoe that’s not even close because they used an aftermarket cross-reference. This Parts Catalog from GEHL gives you the factory part numbers, the hardware grade specs, and the exploded diagrams so you order exactly what goes back on the machine.

GEHL CA670 Frame and Divider: Pages 4-9

The Frame section (pages 4-5) lists the main structure components: outside frame rails, stand pins, wear shoes. You get the exact part numbers – no generic substitutions. The Divider section (pages 6-9) covers the internal dividers that guide the crop. Each part is illustrated with a reference number and the GEHL part number. Page 4 shows the exploded view with callouts. If you need a stand pin, the part number is 058294. Don’t assume a universal pin will work – it won’t.

Important Hardware Notes – Don’t Order Blind

On page 3, you’ll find the hardware note that tells you all cap screws are Grade 5, cadmium plated unless noted. Hexagon nuts are Grade B for Grade 5 bolts, Grade A otherwise. If you ignore this and use a Grade 2 bolt, you risk shear failure. The manual lists abbreviations like HHCS (Hexagon Head Cap Screw), HTFS (Hexagon Thread-forming Screw), etc. Use these to decode the parts list. For a deeper understanding of bolt grades in high-stress applications, read this Wikipedia article on diesel engines – the same principles apply to your attachment.

Gatherer Drive and Gatherer – Pages 10-13

These two sections cover the chain drive and the gathering fingers. Page 10-11 show the Gatherer Drive – sprockets, chains, bearings. Page 12-13 show the Gatherer assembly itself. If you need a replacement chain, the parts list gives you the correct pitch and length. No guessing. Aftermarket catalogs often combine these sections into one generic drawing – this manual keeps them separate so you don’t order the wrong subassembly.

Decal Location and Numerical Index – Pages 14-15

Two pages. One for decals, one for the index. Page 14 maps every decal on the unit – safety decals, identification plates. If a decal is missing, you need the correct part number. Page 15 is the Numerical Index: a master list of every part number in the catalog, sorted numerically. Start here if you already have a part number and want to find where it goes. Speeds up the search.

3 Sections You’ll Reference Most

Frame, Divider, and Gatherer Drive. That covers 90% of the parts you’ll ever order on a CA670. The Frame section alone has 12 items on page 4-5. The Divider section spreads across 4 pages because of the complexity – it includes the divider sheet metal, support brackets, and attachment hardware. Knowing which section to flip to saves time when you’re under the machine. The Gatherer Drive on pages 10-11 includes sprockets, bearings, and chain. If you need a replacement chain, the parts list gives you the exact pitch length and number of links – no guesswork. I’ve had to reorder parts because a generic catalog listed a chain that was two links too long. That mistake costs you a day. This catalog eliminates that.

Why OEM Documentation Matters

I won’t use aftermarket parts catalogs. Too many errors. This one is printed by GEHL with their own part numbers. The model and serial number is stamped on a plate on the right side of the main frame next to the right attachment stand (page 3 tells you where). When you call a dealer, you give them the numbers from this manual – they’ll know. For other GEHL attachments or loaders, check the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog, the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs, and the GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual. All from the same source.

If you want to understand how the diesel engine powering your tractor affects the attachment’s operation, refer to this Wikipedia article on diesel engines. The torque and RPM of the PTO matter for the gatherer drive.

How many pages does this Parts Catalog have?

16 pages. That covers Frame, Divider, Gatherer Drive, Gatherer, Decal Location, and Numerical Index.

Does this manual include repair procedures or torque specs?

No. This is strictly a parts catalog – exploded diagrams and part numbers. You need the GEHL service manual for torque values and assembly steps. But without correct parts, you can’t even start the repair. The hardware note on page 3 does specify that cap screws are Grade 5 and cadmium plated – that’s a spec you need for ordering replacements.

How do I find the correct part number for a worn gatherer finger?

Flip to the Gatherer section (pages 12-13). Find the illustration, locate the finger on the diagram, note the reference number, then cross-reference that number in the parts list beside the illustration. The list gives the GEHL part number and quantity required. If you can’t find it, use the Numerical Index on page 15 – search by the part number if you have it.

Can I use this manual if my CA670 has been modified?

The manual covers the factory configuration. If modifications were made using GEHL-approved parts, they may still be listed. For non-factory modifications, you’re on your own. Always verify the serial number plate location (right side of main frame next to right attachment stand) to ensure you have the correct revision.
