  WARNING
Important information for using an engine with one of the designated spare parts (replacement engine):
t  Take note that the roller tappet is not included in the scope of supply of the new replacement engine.
t  When exchanging the replacement engine, the roller tappet has to be used, if this is possible.
t  The following parts will be influenced if the roller tappet is not installed: Camshaft, high-pressure pump and cylinder head cover.
t  The cylinder head may also be influenced as a result of damage to the bolt of the high-pressure pump.
t  The engine will be damaged permanently if the valves make contact with the piston.
Operation process
Installation is carried out in reverse order, noting the following:
  Note
t  When fitting, replace the self-locking nuts and bolts.
t  Renew bolts which have a specified tightening angle, as well as seals and gaskets.
t  Secure all hose connections with the correct hose clips (same as original equipment) → Parts catalogue.
t  Clean input shaft splines and, for used clutch plates, hub splines; remove corrosion and apply a thin coat of grease → Parts Catalogue to the splines. Then move the clutch plate on the input shaft from side to side, until the hub moves smoothly on the shaft. Excess grease must be removed.
For vehicles with automatic Gearbox
–  Install the engine / gearbox assembly with mounted particulate filter.
Continued for all vehicles
–  Lower engine and gearbox and simultaneously guide stud bolt on left mount into console. Then install the left mount.
  Note
Use vehicle jack to align engine/transmission unit and position in rear area of transmission.
   
–  Position the fastening sleeves -2- of the engine mounting correctly.
–  Tighten the attachment nuts -1- for the engine bracket by hand. For this purpose, the engine must have been aligned in the correct position before tightening.
For vehicles with manual gearbox
–  Mount the clutch slave cylinder → Rep. gr.30.
  Note
  A10-0088
t  Replace the fastening bolt; tightening torque: 23 Nm.
t  The clutch slave cylinder must be pre-tensioned till the securing bolt can be set easily.
t  Before fitting the clutch slave cylinder into the gearbox housing, lithium grease must be applied in the area -a- of the sleeve → Spare parts catalogue.
t  Apply a thin coat of copper grease to the contact surface for the tappet on the clutch release lever → Spare parts catalogue.
–  Install the gear selection mechanism → Rep. gr.34.
For vehicles with automatic Gearbox
–  Install the ATF pipes as well as the ATF filter of the automatic gearbox → Rep. gr.37

  Note
t  Do not bend the selector shaft lever when pressing on the selector lever cable, as it will otherwise no longer be possible to precisely adjust the gearbox.
t  Do not bend or twist the selector lever cable.
t  Before fitting, lubricate the ball socket of the selector lever cable with polycarbamide grease. For correct version, refer to → Electronic spare parts catalogue.
  A37-0410
–  Press in the ball socket of the selector lever cable -1- to the lever of the selector shaft.
–  Tighten the screws -2- that are used to secure the bracket for the selector lever cable on the gearbox to 23 Nm.
Continued for all vehicles
–  Install the starter electric connectors → Rep. gr.27.
  Note
