GEHL SL4640, SL4840, SL5640, SL6640 2007 Parts Catalog

You are in the middle of a teardown on a SL6640 and the parts guy asks for the engine serial number before he’ll hand over a new head gasket. You already know why: the Deutz 2011 series has running changes that don’t line up with model years or serial number ranges. Order one wrong part and you’re staring at a bare block for three days. That’s exactly why this GEHL SL4640, SL4840, SL5640, SL6640 2007 Parts Catalog belongs on your bench. It is the factory-issued parts breakdown from Gehl, not a reprint from some third party that re-numbers everything. The PDF is 88 pages of exploded views and callouts with genuine OEM part numbers, keyed to the exact engine serial numbers listed on page 1.

Deutz F3M/F4M 2011F: Engine Coverage

Page 1 spells out the four engine variants covered: F3M 2011F (SN 0654097 and later), BF3M 2011F (SN 0590544 and later), F4M 2011F (SN 0529127 and later), and BF4M 2011F (SN 0550682 and later). The three-cylinder engines (F3M and BF3M) go into the SL4640. The four-cylinder engines (F4M and BF4M) go into the SL4840, SL5640, and SL6640. If you are working on a skid-steer that falls outside those serial number breakpoints, the manual tells you that earlier versions use a different parts set. No guesswork—the cutoffs are printed right on the page. Every chapter in the table of contents, from REAR END COVER (page 1) through CYLINDER HEAD (page 18) and beyond, gives you the exact part number you need to order from your Gehl dealer.

7 Systems Broken Down by Group

The catalog organizes 88 pages into discrete assemblies: REAR END COVER, GUIDE TUBE, DIPSTICK, CRANKCASE ACCESSORIES, CRANKCASE BREATHER, ENGINE BLOCK, OIL PAN, CRANKSHAFT ACCESSORIES, CRANKSHAFT, POWER TAKE-OFF, COVER PLATE, FLYWHEEL, CONNECTING ROD, PISTON, FILLER CAP, CYLINDER HEAD FASTENINGS, CYLINDER HEAD, and more. Each section shows an exploded diagram with callout numbers and a corresponding parts list. If you need a dipstick tube for a BF4M 2011F, you flip to the GUIDE TUBE section, find the figure, and read the part number. No scrolling through generic websites that claim to have the part but send you a different-length tube. The catalog also includes a Numerical Index so you can look up a part number and find which assembly it belongs to.

Ordering Parts: Have Your Serial Number Ready

The introduction on page 2 is worth reading twice. Gehl explicitly states that Deutz engine service parts are driven by individual engine serial numbers, not ranges. Running changes during assembly may be unique to that engine. If you call your dealer and give them the model number only, you risk getting the wrong piston, wrong injector, wrong anything. The manual tells you exactly where to find the serial number (on a plate on the valve mechanical cover) and what info to provide: correct part number, full description, quantity, engine model, and serial number. That level of specificity keeps your rebuild from turning into a parts-chasing nightmare.

Why This Beats Aftermarket Catalogs

Aftermarket parts catalogs often re-index part numbers or leave out superseded items. This manual comes straight from Gehl, dated May 2007 (Revision C). The part numbers printed here are the ones Gehl’s own system uses. If you try to cross-reference from a generic online database, you are gambling with your time and your customer’s machine. I have seen too many guys order a crankshaft seal from an aftermarket PDF that showed the wrong dimensions because they used a reprint from a different model year. Stick with the factory source. For a broader view of the whole machine, consider the Gehl SL4640 SL4840 SL5640 SL6640 Service Manual that covers diagnostics and repairs beyond the parts list. If you need parts catalogs from adjacent years, the GEHL SL4640 SL4840 SL5640 2009 Parts Catalog and GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog are also available on this site.

Who Should Use This Catalog

If you own a SL4640, SL4840, SL5640, or SL6640 and ever plan to rebuild the Deutz engine instead of swapping it, you need this PDF. Home garage mechanics who do their own wrenching will save the cost of the manual the first time they order the correct head gasket. Shop owners who keep a fleet of these loaders will want a copy at every tool box. Beginners might find the exploded views intimidating initially, but the instructions for ordering parts are dead simple—find the engine serial number, look up the figure, write down the part number. For background on how diesel engines of this type operate, you can read this Wikipedia article on diesel engines. But for parts identification, this catalog is your single point of truth.

Source Authenticity: OEM Factory Print

The file we sell is a direct scan of the original Gehl printed manual (Form No. 917108, Revision C, 05/07). It is not a copy of a copy or a re-typeset PDF. The 88 pages include the exact formatting, part callouts, and notes that Gehl authorized. You get the same information that a Gehl dealer sees. No aftermarket publisher has reviewed or verified the content—Gehl did. That is the difference between getting the job done and getting it wrong.

Does this parts catalog cover the SL5640 with a BF4M 2011F engine?

Yes. The four-cylinder engines (F4M and BF4M) are used in the SL4840, SL5640, and SL6640. Check the serial number cutoff on page 1—BF4M 2011F with SN 0550682 and later.

Will this catalog work for a 2005 SL4640 with a different engine?

It covers F3M 2011F engines with serial number 0654097 and later. If your engine serial is earlier, the parts may differ. The manual clearly states the serial number breakpoints. For earlier models, see the 2005 catalog linked above.

What if I cannot find the engine serial number on the valve mechanical cover?

The number is stamped on a plate on the valve mechanical cover. If the plate is missing or illegible, contact a Gehl dealer with the loader serial number—they can look up which engine originally shipped with that unit.

Are torque specs included for the cylinder head fasteners in this parts catalog?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. For torque values and assembly procedures, you need the separate service manual.
