1 - Bolts  
❑ Renew after removal  
❑ Apply engine oil to  
thread and contact sur‐  
face  
❑ Use old bolts to meas‐  
ure radial clearance.  
❑ 45 Nm +90°  
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.  
❑ Separating new conrod  
⇒ page 139 .  
3 - Bearing bushes  
❑ Fitting position ⇒ page  
132  
❑ 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 ⇒ 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.  
❑ Separating new conrod ⇒ page 139 .  
❑ Measuring radial clearance ⇒ page 139  
5 - Pressure relief valve  
❑ 27 Nm

❑ Installation position: arrow on piston crown faces towards pulley end  
❑ Mark allocation to cylinder  
❑ Checking piston and cylinder bore ⇒ page 136  
10 - Compression rings  
❑ Offset gaps by 120°  
❑ Installation position: “TOP” or “R” marking must face upwards towards piston crown.

⇒ Fig. ““Checking ring-to-groove clearance”“, page 137  
11 - Oil scraper ring  
❑ 2-part or 3-part, depending on version  
❑ Install in such a way that upper gap of three-part oil scraper ring is offset by 120° relative to adjacent  
compression ring
