Removing and installing motor/pump unit
Special tools and workshop equipment required
t  Drip tray -V.A.G 1306-
t  Torque wrench -V.A.G 1331-
t  Torque wrench -V.A.G 1332-

t  Repairs must not be performed on the motor/pump unit
t  If problems are reported, determine the cause by means of a function test, pressure test, leakage test and „Guided Fault Finding“.
t  If a fault is found, the motor/pump unit must be renewed.
t  Residual quantities of hydraulic fluid will remain in the motor/pump unit and in the return line and pressure line after the fluid has been drawn off.
t  Do not re-use hydraulic fluid which has been drained off.
t  The pressure line and return line must not be clamped off with hose clamps, e.g. -3094-, or other tools. Applying a clamp to these lines can cause damage.
t  When bending or repositioning the pressure line or return line, make sure that the bending radius is not less than 100 mm to prevent damage to the lines.
