2K800/2K801/2K802  

Initial 

Installation 

EN 4161.758.103m – 2015-10

Fill the gearbox with oil and connect up the 
recirculating lubrication system and the power 
supply. The breather outlet must always be at the 
top, regardless of the installation position. Tighten 
by max. 1 turn if necessary. 

The gearbox is now ready for use.

CAUTION 
The gearboxes can be operated under the same 
degrees of protection as those defined for AC 
and DC motors. 

When setting up, make sure that the motor  
cooling air can flow in and out unhindered. 

NOTE 

Before taking the electric motor/gearbox assembly 
into operation, check that the gearbox output can 
be turned by hand. 

In the case of drive units that are fixed on the 
gearbox flange, support the motor on the B-side 
so that it does not vibrate.

Output 

3.5.1

 

Version with belt output 

The belt pulley must be centered on the outer 
diameter of the output flange (tolerance K6),  
fastened with the bolts so that it is frictionally  
engaged and secured. Comply with the specified 
tightening torques. 

The belt pulley should be balanced to quality 6.3 
as per VDI Directive 2060 in order to ensure low-
vibration operation. 

CAUTION 
Note the maximum specified tensioning force 
when tightening the belts in order to prevent 
bearing overload. 

The average belt force must be between the 
bearings. When assembling, it must be possible 
to easily slide the belt pulley onto the output 
shaft. Heat the belt pulley if necessary. 

 

3.5.2

 

Version with coaxial output 

In the case of the version with coaxial output 
(shaft stub), also note the balancing type for the 
output (see chap. 3.2). The gearbox is delivered 
with full-key balancing. 

Refer to the installation drawing for the fitted  
key dimensions. Always fix the fitted keys using 
threaded pins. 

 

3.5.3

 

Version without output 

The output shaft is not supplied by ZF. It is 
manufactured by the customer. Refer to the 
installation drawing for a proposal of how the 
connection point for the output shaft should be 
configured with the DIN 5480 profile. Apply a 
suitable bolt locking compound (e. g. Loctite no. 
275 or no. 243) to the M12 cap screw and tighten 
to 115 Nm.
