1 - Bolts  
❑ Renew after removal  
❑ Apply engine oil to  
thread and contact sur‐  
face  
❑ Use old bolts to meas‐  
ure radial clearance.  
❑ 45 Nm +90Β°  
2 - Conrod bearing cap  
❑ Observe installation po‐  
sition  
❑ Conrod bearing cap on‐  
ly fits in one position  
and only on the appro‐  
priate conrod due to  
the cracking procedure  
separating the cap from  
the conrod  
❑ Mark allocation to cylin‐  
der and conrod in col‐  
our -A-  
❑ Installation position:  
Marking -B- faces to‐  
wards pulley end.

❑ Renew worn bearing  
shells  
❑ Apply engine oil before  
installing  
❑ Axial clearance  
♦ New: 0.10 to 0.35 mm  
♦ Wear limit: 0.40 mm  
❑ Measuring radial clearance β‡’ page 139  
4 - Connecting rod  
❑ Renew as set only.  
❑ Mark allocation to cylinder and to conrod bearing cap  
❑ Installation position: Marking -B- faces towards pulley end.
