Sprocket for water pump/balancer shaft, genuine GM
The water pump and the two balancer shafts are driven by gears.
The crankshaft is fitted with a special gearwheel with a shock absorber, which is NOT included in any aftermarket timing chain kit. The crankshaft sprocket in cheap accessory kits CANNOT be used in the GT engine.
The sprocket is no longer available from Opel or GM and also no longer available in the USA. If you ever plan to replace the secondary timing chain with your own aftermarket material, this original spare part is a must.
Scope of delivery:
- Crankshaft sprocket with shock absorber (original GM 55557168)
Gasket set secondary drive, only
29,99 Euro
Please also remember the required seals for the front cover, Made in Germany, which we also offer. Regardless of whether you are replacing the primary or secondary timing chain, the identical seal set is only required once!
Hint:
When replacing the secondary timing chain, it is advisable to replace the water pump and the primary timing chain drive.
