GEHL SL5640E, SL6640E 2010 Parts Catalog

You need a part for your GEHL SL5640E, SL6640E 2010 Parts Catalog. You call the dealer. They ask for the part number. You flip through a beat-up aftermarket catalog and find something that looks right. It arrives. Wrong thread pitch, wrong bushing diameter, or it doesn’t fit the serial number you have. That’s billable hours down the drain. This OEM factory print – 256 pages – stops that. Every exploded view, every part number, every callout comes straight from GEHL’s engineering department. No reprints. No third-party guesswork.

Understanding the GEHL SL5640E, SL6640E 2010 Parts Catalog Layout

This catalog is split into two main sections. Section A covers the main loader component with 24 sub-sections starting from the chassis on page 1 through decals on page 142. You get everything: grille and engine cover, ROPS/FOPS structure, restraint bar, seat and seat belt options, lift arm, attachment bracket with Power-A-Tach®, wheel drives, engine on page 35, air cleaner/exhaust, radiator/cooler, hydrostatics, hydraulics (both chassis and lift arm), controls for wheel drives, lift/tilt, auxiliary hydraulics, engine controls, electricals split by chassis, ROPS/FOPS, lights, engine, and control circuits, plus four-point lift, sound suppression, tires, and decals. That is depth you only get from an OEM document.

Section B dives into hydraulic components – lift cylinder and associated hardware. Each hydraulic line, fitting, and seal is listed with the GEHL part number you need. this Wikipedia article on diesel engines explains basic diesel architecture, but when you need to order a gasket or injector line for your Yanmar or Deutz power plant, this catalog is where you live.

Engine Section: What Page 35 Tells You

Page 35 lists every engine component – block, head, oil pan, gaskets, fasteners. The parts list calls out quantities and notes any special lubrication or nonstandard torque values right behind the part number. For standard fastener torque specs, the inside back cover has a table. If a bolt needs thread locker or a specific angle, it is printed there. You won’t find that in a generic aftermarket parts book. Use this page when you are rebuilding a motor or replacing a cracked manifold.

ROPS/FOPS and Restraint Bar: Safety Parts You Don’t Skip

Safety structures – ROPS/FOPS on page 17, restraint bar on page 19 – are not places to gamble with aftermarket alternatives. The load-tested cage design, the mounting brackets, the hardware grades are all specified here. One wrong bolt in a rollover situation and you are writing a report instead of walking away. This catalog gives you the exact GEHL replacements so you can sleep at night.

If you need to know how to tear down the hydrostatic drive, that is the book. GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog is an older generation – verify serial numbers before using. GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs covers larger models. For your SL56 or SL66 series, this 2010 catalog is current.

How to Identify Your Machine’s Serial Number Range

Page 1 of the catalog lists the exact serial number breaks. For SL5640E: 511701 and up (standard), 511501 and up (EU). For SL6640E: 608301 and up (standard), 608101 and up (EU). If your machine predates those, you need an earlier edition. Always check the serial number decal on the left chassis upright – that is where GEHL stamps it. Ordering a part for the wrong range means holes don’t line up. I have seen it happen more times than I care to count.

Hydraulic Component Breakdown – Section B

Section B starts after page 142 and covers the lift cylinder in full detail. Hoses, seals, pistons, rod ends – each with a GEHL part number. If you need to rebuild a leaking lift cylinder, you flip to that section, cross-reference the illustration, and write down the part numbers. Do not trust aftermarket interchange tables; they often use a generic spec that skips the thread pitch or port size variant GEHL engineered. this Wikipedia article on diesel engines won’t help you there – this catalog will.

Source Authenticity: OEM Print vs Aftermarket Reprints

This manual is a factory GEHL document, form number 917341, revision C dated 06/10. It is not a scanned PDF of a scanned copy that lost resolution on the wireframe diagrams. The illustrations are crisp, the part numbers are legible, and the dimensions are in inches. Aftermarket catalogs often omit the note about replacement batteries – GEHL does not supply them, and the specs are in the Electrical-Chassis chapter. Reprint houses skip that detail because it is not a part number. That gets you a battery tray that fits wrong or cables too short. OEM documentation catches those details because the manufacturer wrote it for their dealer network, not for the lowest printing cost.
