Mercedes-Benz Service Manual V-8 Engines M116 (3.5-ltr.), M117 (4.5-ltr.) | PDF
Technical service coverage for Mercedes-Benz V-8 M116 3.5-liter and M117 4.5-liter engines, with applications in the brand’s classic sedans, coupés, and roadsters.
This edition covers the first generation of the Mercedes-Benz M116 and M117 V-8 engines, used in classic models from the W108, W109, W111, W107, and W116 series. Because it focuses on the early 3.5- and 4.5-liter versions, it is especially valuable for repair, maintenance, diagnosis, and restoration work on Mercedes-Benz vehicles from the late 1960s and the 1970s.
Unlike the later M116 and M117 V-8 manuals, this PDF focuses on the initial stage of the engine family, with direct coverage for engines 116.980, 116.981, 117.981, 117.982, 117.983, 117.984, 117.985, and 117.986. It includes inspection, disassembly, measurement, machining, assembly, and adjustment procedures, along with technical tables, tightening torques, special tools, and original service illustrations.
To verify the contents of this edition, you can consult the Full Index tab, where the manual groups and operations are presented.

Important clarification: the models listed above help identify the main applications related to this first generation of the Mercedes-Benz V-8 M116 3.5-liter and M117 4.5-liter engines. Some are explicitly listed in the manual, while others are included as a reference because they share the same mechanical base as the versions developed in this edition. For that reason, the content may also be useful for diagnosis, maintenance, repair, and restoration work on other technically related classic Mercedes-Benz models.
This publication corresponds to the workshop manual for the Mercedes-Benz V-8 M116 3.5-liter and M117 4.5-liter engines. For the later 3.8- and 5.0-liter variants, or the 4.2- and 5.6-liter versions, a different edition applies. Before buying, the best approach is to verify the exact engine code installed in the vehicle and review the Complete Index tab. The file is supplied in PDF format with bookmarks for easier chapter navigation, preserves the original technical content of the printed edition, and can be consulted from a PC, tablet, or smartphone, while also allowing you to print only the pages needed for each job.

Frequently asked questions about the Mercedes-Benz M116 3.5 and M117 4.5 engine manual
How can I tell whether this M116 and M117 manual is the right one before buying?
The safest way is to check the exact engine code installed in the vehicle. This edition corresponds to the first generation of the M116 and M117 V-8 family and covers the 3.5- and 4.5-liter variants, not the later 3.8- and 5.0-liter versions or the 4.2- and 5.6-liter versions.
Is this PDF only for 450 models, or can it also help with other early V-8 applications?
It is not limited to the 450 models. It can also be useful for vehicles fitted with the M116 3.5 and M117 4.5 engines used in classic Mercedes-Benz series such as W108, W109, W111, W107, and W116.
Does the content include internal engine work, or only basic maintenance tasks?
It includes much more than basic maintenance. The manual covers compression testing, leak testing, cylinder evaluation, oil consumption, engine removal, cylinder head work, crankshaft assembly, pistons, seals, flywheel service, and other deeper repair procedures.
Does it include information on valve timing, valves, and the timing chain?
Yes. The manual includes valve adjustment, hydraulic compensating elements, camshaft timing, chain tensioner work, timing chain replacement, guide rails, and other procedures related to the V-8 valve train and timing system.
Does it cover injection and ignition systems?
Yes. Among the groups covered are the CIS mechanical fuel injection system, the electronically controlled fuel injection system, and various ignition and timing procedures, which are especially useful for diagnosing classic Mercedes-Benz engines.
Is it a good reference for restoring classic Mercedes-Benz models with these V-8 engines?
Yes. Because of its focus on the early M116 and M117 variants, its technical tables, workshop procedures, and original illustrations, it is a very useful reference for serious restoration, correct maintenance, and repair of classic Mercedes-Benz models equipped with these V-8 engines.
