ZF Friedrichshafen AG, also known as ZF Group, and commonly abbreviated to ZF (“ZF” stands for “Zahnradfabrik” which means “Gear Factory”). ZF is a German car parts maker headquartered in Friedrichshafen, in the south-west German region of Baden-Württemberg.
Specialising in engineering, it is primarily known for its design, research and development, and manufacturing activities in the automotive industry. It is a worldwide supplier of driveline and chassis technology for cars and commercial vehicles, along with specialist plant equipment such as construction equipment. It is also involved in rail, marine, defence and aviation industries, as well as general industrial applications. ZF has 113 production locations in 26 countries with approximately 71,500 employees.
ZF Marine Transmissions is a subsidiary of the ZF Group ($14 billion in annual sales). ZF Marine is now the largest supplier of marine transmissions, propellers, surface drives, and controls in the world.
The company was founded in 1915 in Friedrichshafen, Germany by Ferdinand von Zeppelin, to produce gears for Zeppelins and other airships. Zeppelin was unable to otherwise obtain gears for his airships.
By 1919, ZF had moved into the automobile market, a move consolidated by the terms of the Treaty of Versailles. Some of the most important milestones that followed:
- 1921: Under a rampant inflation and investor fears, the company goes public as the Zahnradfabrik Friedrichshafen AG, with the Zeppelin Luftschiffbau GmbH holding 80% of the stock options, valued at 4 million Marks.
- 1929: A thriving auto industry warrants the series production of the innovative helical ZF Aphon transmission for cars and commercial vehicles
- 1944: On 3 August, the Zahnradfabrik was bombed by the Fifteenth Air Force.
- 1953: Market launch of the first fully synchronised transmission for commercial vehicles worldwide.
- 1961: Development of a fully automatic transmission for passenger cars. The 1960s sees ZF supplying transmissions to major German automakers (including DKW, Mercedes-Benz, Porsche and BMW) as well as Peugeot and Alfa Romeo.
- 1986: Start of USA transmission production in Gainesville, Georgia, for pickup trucks. ZF became a major supplier to Ford in the 1980s.
- 1995: ZF Acquires the Italian-based Hurth Marine Gear which continues to produce the smaller gears under the ZF name.
- 2001: ZF Acquires Mathers Marine Controls. Mathers Controls, introduced the industry’s first single lever control over 50 years ago, and has been the leader in the industry with electronic engine controls such as the MicroCommander system for marine vessels, yachts, and pleasure boats.
- 2013: ZF Opens Passenger Car Transmission Plant in the U.S.
- 2014: Acquires American auto parts manufacturer TRW Automotive for $13.5 billion.

Frequently Asked Questions
What oil is in my transmission?
Models 5 through 85 will primarily use automatic transmission fluid. Models 220 through 60000 will generally use SAE 30W monograde engine oil. Refer to ZF FIlter & Lubricant Cross Reference (PDF) from www.marinepartsexpress.com for specific instructions or contact ZF.
What is my oil capacity?
Capacity is listed on Spec Sheet for your model. Look under the dimensions table. Many models have the capacity right on the gear on the ZF data tag.
STANDARD CONFIGURATION (WITHOUT NAME EXTENSION)
- Reversing transmissions
- 3-Shaft configuration
- Vertical offset (input above output)
- Parallel offset
OTHER CONFIGURATIONS / MODEL DESIGNATIONS
|No Letter||Vertically Offset (input above output)|
|IV||Integral Vee-drive (flanged on to engine)|
|M||Mechanical clutch actuation|
|TS||TS: 2-Speed (power-shifting)|
|NR2||Non-Reversing, two shafts (input above output)|
|NR2B||NR2B: Non-Reversing, two shafts (input below output)|
|NR2H||Non-Reversing, two shafts (input horizontal output)|
|SG||Spur Gear (additional primary gear stage)|
These designations for shaft rotation are not part of the model name but the required shaft rotation must be specified when ordering the transmissions. This is particularly important for non-reversing (NR) transmissions.
- Engine-Wise (EW): output shaft rotates in same direction as input shaft or
- Counter Engine-Wise (CEW): output shaft rotates in opposite direction to input shaft
For the standard, reversing transmissions, unless specifically stated, full power can be transmitted through either the forward or reverse gear trains.

Ratings apply to marine diesel engines at the indicated speeds. At other engine speeds, the respective power capacity (kW) of the transmission can be obtained by multiplying the Power/Speed ratio by the speed. Approximate conversion factors:
1 kW = 1.36 metric hp
1 kW = 1.34 U.S. hp (SAE)
1 U.S. hp = 1.014 metric hp
1 Nm = 0.74 lb.ft.
1 Kg = 0.454 lb
Ratings apply to right hand turning engines, i.e. engines having counterclockwise rotating flywheels when viewing the flywheel end of the engine. These ratings allow full power through forward and reverse gear trains, unless otherwise stated. Contact your nearest ZF Sales and Service office for ratings applicable to gas turbines, as well as left hand turning engines, and marine transmissions for large horsepower capacity engines. Ratings apply to marine transmissions currently in production or in development and are subject to change without prior notice.
NOTE: The maximum rated input power must not be exceeded (see respective ratings in the technical data sheets).
