Assembly Instructions CB 280

Grind the cam ring surface 
around the roll pin holes with 
a fi ne grinding stone.
 

 

It is very important to 

clean the cam ring good 

before assembling! 

Grind the spacer ring over the 
roll pin holes with a fine grind-
ing stone on both sides of the 
spacer ring. Do not grind on the 
sliding surface for the roller.

The highest cleanliness

 of the motor parts and of the 

workplace are basics to ensure the smooth functioning 
of the hydraulic motor!

Make sure to minimise that contamination can enter 
into the motor during the assembling.

Ensure that you have cleaned all motor parts thoroughly, 
especially if you have re-machined, grinded or in some 
other way worked up the motor parts.

After final cleaning of the motor parts, don’t leave the 
parts too long before assembling.

When lubricating

•   always use clean filtrated oil, recommended ISO class 
    16/13 according to ISO 4406, NAS.7,
•   always use clean grease of type Texaco Multifac EP2 
 or 

equivalent.

Rust protection

Use Shell Ensis SX or equivalent rust protection fluid.

Always use new gasket set.

Sliding surface

Important preparation before assembly

Work to be done before 
cleaning the motor parts:

Always treat the sliding 
surfaces with care

Shaft end housing

Connection block and valve plate
