General

This booklet covers both the single axle gear 
RP832 and the bogie axle gear RBP832. Unless 
otherwise instructed, the procedures apply to 
both types of central gear. Numbers in the 
directions refer to associated illustrations or 
exploded view drawings at the front of the 
booklet.

Setting press force

•

The press force attained depends directly on 
the hydraulic pressure from the air driven 
pump. The hydraulic pressure delivered by 
the pump depends on the input air pressure, 
which is governed by a pressure regulator.

•

The air pressure can be changed with knob 
D. Pull the red locking ring towards the 
knob and set the desired pressure which can 
be read on the manometer C.

B  Connection for compressed air

Diagram on pump housing

•

Set the press force to 120 kN (12 tonnes) as 
follows:

•

Follow the press force axis (the bottom axis) 
to the right until you reach 120 kN.

•

Then follow the line straight up until it 
meets the bold diagonal line.

•

Draw a horizontal line to the left from this 
intersection. This will end up on 5.2 bar, 
which is the pressure required for a press 
force of 120 kN.
