Warning Read and follow the safety precautions and general instructions and also the SKF instruc-
tion "Safety and general instructions for lubrication systems."." Failure to follow these instructions could
result in serious injury or damage to the lubrication system or the equipment that is lubricated.
1 General description
Note! Numbers in brackets are part numbers of drawings 461780 and 461803.
A doser group consists of a mounting rail (pos.1) and one or several dosers (pos.2) fastened to it. The mounting rail
divides the lubricant to the dosers, which feed the adjusted amount of lubricant to the lubrication points.
Note! B doser is suitable for use with lubricants up to the class NLGI-1.
2 Design
The doser includes a charging valve (pos.3), a dosing chamber (pos. 4), a dosing piston (pos.5) and a spring (pos.6). B6
doser is equipped with a dosage adjustment screw (pos.7).
3 Operation
3.1 B doser
The pressure in the line increases during pressurisation and the doser charging valve moves to its upper position. At
the same time lubricant flows past the charging valve and moves the dosing piston to its upper position. When the
dosing piston moves to its upper position, it pushes the adjusted lubricant dosage from the dosing chamber to the lu-
brication point.
After pressurisation the line pressure decreases and the charging valve moves to its lower position and closes. The
spring returns the dosing piston to its lower position and at the same time lubricant flows above the dosing piston to
the dosing chamber.
The line can be pressurised again when the pressure in the line has decreased and the dosing pistons of the dosers
have returned to the lower position.
3.2 The unfastening and fastening of dosers
The dosers are unfastened and fastened with a socket wrench.

CBDO3AEN.doc 18.03.2014 Rev. 3A 2 (8)
NOTE! When changing the dosers, make sure that there is no pressure in the system.
4 Settings
4.1 Adjustments to the B6-doser
1. Turn open the pipe connector of the doser’s lubrication piping outlet.
2. Turn open the locking nut in the upper part of the doser.
3. Adjust the dosage by turning the adjustment screw located above the locking nut.
4. Tighten the locking nut in the upper part of the doser.
5. Tighten the pipe connector of doser’s lubrication piping outlet.

6 Troubleshooting
Note! Check the lubricant requirements from the manufacturer of the vehicle and the properties of the lubricant
from the lubricant manufacturer. Note that in addition to the application, operating temperature, rotation
speed and operating environment are also relevant factors when choosing the lubricant. For more infor-
mation on grease pumpability, please contact Oy SKF Ab.
Note! The lubrication disturbances of the critical lubrication points must be repaired immediately, since inade-
quate lubrication rapidly damages the equipment or machinery that is lubricated.
Note! In the event that the operation disturbance can not be repaired with the help of these instructions, please
contact the supplier immediately.
