Grease Purge and Grease Drain Cup

Some versions of the NEMA (or IEC) adapters also include a 

grease purge and a grease drain cup (1299) for collecting old 

grease.  The grease purge area is sealed for transportation. 

It is recommended that the G1/4 sealing screw (1297) be re-

moved and that the grease drain cup be installed after the 

automatic lubricant dispenser is activated.

The swivel fitting (1242) that NORD supplies allows the grease 

cup to be positioned at a 90

°

 angle from its typical mounting.  

The swivel fitting allows the grease cup to be rotated so that 

it remains clear of any gear unit mounting obstructions.

Grease Cup Servicing

NORD suggests that with every second replacement of the 

automatic lubricator, the grease collection cup (NORD Part 

No. 28301210) should be emptied or replaced with a new 

one.  Follow the steps below to service the grease cup.
1.  Unscrew the grease drain cup (1299) from either the 

outlet port of the NEMA or IEC input cylinder or from the 

extension (1243) that is secured to the NEMA or IEC 

input cylinder.

2.  To empty the grease drain cup (1299) insert a stiff rod 

through the hole in the grey cap-end of the drain cup 

and push the internal plunger towards the thread-end 

of the drain cup. Please note that the dark gray end cap 

is bonded into place and cannot be removed.

3.  Collect and properly dispose of the grease being pushed 

out of the drain cup. Due to the design of the container 

a residual amount of grease may remain in the container.

4.  After emptying and cleaning the grease cup it can be 

fitted back onto the grease outlet port of the NEMA or 

IEC adaptor.

5.  In the event the grease cup becomes damaged or it 

should be replaced with a new container. Consider 

replacing the grease cup (P/N 2830100) with every 

second replacement of the automatic lubricator.

bearing cover area of the NEMA or IEC input cylinder.

3.  Install the new automatic lubricator and activate per the
