I have a 1999 Blazer 4x4 4.3 with the balance shaft. I had the machine work done and the tech installed all the bushings for the cam and rear balance shaft. When tearing down the motor I neglected to loosen the timing gear from the balance shaft prior to removing the timing chain. Behind the upper timing gear on the balance shaft there is a bearing will ball bearings. What is this part named? I would like to replace this in my build however when looking for new parts at Rockauto.com it would appear they are calling the rear bushing a bearing and I have not found the ball bearing part I am seeing on my balance shaft. I will be looking over my manual for this part name so if you can help with this information Thank you in advance.

 

Item #135 from THIS SCHEMATIC. GM OE PN 10105908. The schematic states that this is part of the balance shaft.

 

Thanks for the great information.

 

This bearing was displayed on the Compnine.com website as a part. I purchased mine from a dealer.

 

On this build I ordered this bearing online. I paid $11.73 and that included shipping. This original NSK bearing is stamped with the number 6006 N. In searching for this same bearing I found that the bearing I needed to order is 6006 NR, the R denoting the lock ring on the outer race.
