40/72 Installation
BoschRexrothAG, axial piston variable pump A4VSO, RE 92050-01-X-B1/2019.08.23
No gearing forces higher than thepermissible axial and radial forces should act
onthe shaft; ifnecessary, support thegear wheel atthegearbox output separately.
7.4.6 Installation with cardan shaft
To connect the axial piston unit to the drive motor via a cardan shaft:
1. Place theaxial piston unit near theintended installation location. Allow enough
space for thecardan shaft tofit through onboth sides.
2. Place thecardan shaft onthe output shaft ofthedrive motor.
3. Push theaxial piston unit tothe cardan shaft and place thecardan shaft onthe
drive shaft oftheaxial piston unit.
4. Bring theaxial piston unit tothe installation position and fasten it. Details on the
required tools and tightening torques for the mounting bolts can be obtained
from the system manufacturer if required.
7.4.7 Completion of assembly
1. Remove any installed transport screws.
CAUTION! Operation with protective plugs!
Operating theaxial piston unit with protective plugs may result ininjury ordamage
tothe axial piston unit.
▶ Before commissioning, remove all protective plugs and replace them with
suitable, pressure-resistant connecting fittings.
2. Remove thetransport protection.
The axial piston unit comes with protective covers(1) and protective
plugs(2).They are not pressure-resistant and have tobe removed prior
toconnection. Use a suitable tool for this to prevent damage to the sealing and
functional surfaces. If sealing orfunctional surfaces are damaged, contact your
BoschRexrothservice partner ortheservice department ofthefactory that
manufactured theaxial piston unit.
