ate shaft sprocket is coated with a solid film lubricant that wears  
off after a short period and thus automatically sets the tooth  
backlash.

Installing  
Note  
Due to the small amount of play between the balance shaft and  
cylinder block, the balance shaft may need to be installed chilled.  
Check whether the balance shaft can be fitted into the cylinder  
block without exerting force. If this is not the case, the balance  
shaft must be chilled before installing.  
Specified torques ⇒ page 127 .  
– Place new balance shaft in freezer compartment for 30 mi‐  
nutes or spray with commercially available chilling spray.  
– Lubricate balancer shaft bearing with engine oil.  
– Install new balancer shaft for inlet camshaft and tighten bolt  
-2-.  
– Renew O-ring -1- and lubricate with engine oil.  
– Lubricate bearing mounting with engine oil and insert  
-arrow-; bearing mounting must engage in bore in cylinder  
block.  
Caution  
The intermediate shaft sprocket must be replaced. Otherwise  
no tooth backlash is set - engine damage. The new intermedi‐  
ate shaft sprocket is coated with a solid film lubricant that wears  
off after a short period and thus automatically sets the tooth  
backlash.
