Caution  
Warning, aluminium cylinder block! The crankshaft and pistons  
must not be removed. Just loosening the main bearing caps  
will cause deformation of the cylinder block bearing pedestals.  
This deformation will cause a reduction of the bearing clear‐  
ance. Even if the bearing shells are not renewed bearing  
damage could occur due to a different bearing clearance. If the  
bearing cap bolts are loosened, the cylinder block must be re‐  
placed complete with the crankshaft and pistons. Measuring  
the main bearing clearance is not possible with normal work‐  
shop equipment.  
Note  
Secure engine to engine and gearbox support -VAS 6095- to carry out repairs.  
Engine must not be set down on oil sump, as this will damage the liquid gasket between the upper and lower  
sump.  
Finding metal shavings or a large quantity of small metal particles during engine repair could indicate that  
the crankshaft bearings or conrod bearings are damaged. To prevent this from causing further damage,  
perform the following repairs:  
Thoroughly clean oil passages,  
Renew oil return valve,  
Renew oil spray jets,  
Renew oil cooler,  
Renew oil filter.

Removing and installing poly V-belt  
Special tools and workshop equipment required  
♦ Locking pin -T10060 A-  
Removing poly V-belt  
– Remove noise insulation tray.  
– Mark direction of rotation of poly V-belt.  
lk  
– Turn spanner clockwise until tensioning element can be  
locked using locking pin -T10060 A- .  
– Remove poly V-belt.  
Installing poly V-belt  
Note  
Before installing poly V-belt, ensure that all ancillary assem‐  
blies (alternator, air conditioner compressor, vane pump) are  
secured tightly.  
Check that idler roller turns easily.  
When installing poly V-belt, check direction of belt rotation and  
proper seating of belt in pulleys.

– Fit poly V-belt as illustrated.  
After completing repairs always:  
– Start engine and check that belt runs properly.  
1.4  
Checking alignment of poly V-belt  
Note  
Alignment of poly V-belt must always be checked to prevent dam‐  
age if power-assisted steering vane pump, air conditioning sys‐  
tem compressor or the respective brackets for power-assisted  
steering or air conditioning system compressor have been re‐  
newed.  
Special tools and workshop equipment required  
♦ Aligning gauge -3201-  
♦ Torque wrench (5…50 Nm) -V.A.G 1331-  
Procedure  
– Remove power-assisted steering vane pump pulley.  
– Remove poly V-belt ⇒ page 18 .

– Remove idler roller -1-.  
– Position aligning gauge -3201- on air conditioning system  
compressor belt pulley.  
Note  
The air conditioning system compressor pulley must align with the  
power-assisted steering vane pump pulley.  
If belt pulleys do not align  
– Compensate misalignment of pulleys using shims with thick‐  
nesses of 0.6, 0.8, 1.0, 1.2, and 1.4 mm.  
– Check alignment of belt pulleys again with aligning gauge  
-3201-  
– Install idler roller. Specified torque: 25 Nm  
– Install poly V-belt ⇒ page 18 .  
– Tighten power-assisted steering belt pulley securing bolts to  
22 Nm.
