Background
A new screw for the engine connecting rod cap was introduced from and including model year 1998 for all S70/V70/C70 gasoline engines.
The new screw has a closer pitch of thread.
At the end of model year 1997 production approximately 800 engines were manufactured with this new type of screw. It is therefore important to check
which type of screw the engine is equipped with if an engine from a model year 1997 car is being renovated, and whether the screw needs to be replaced.
When replacing screw, it must be replaced with same type of screw, in other words with the same pitch of thread.
This Service Bulletin describes how to spot the difference between the old and the new type of screw, and within which engine serial numbers mixed
screw types are to be found.
