I'm going to be doing a rebuild soon. Figure I'll replace the water pump drive gear & bearing. I have yet to take it apart. Are these one piece or two?
Anyone have the part number(s) for this?

thanks

 

Why? The bearing constanly lubricated and the gears mesh fine. Sorry I dont know where you could find the parts but IMO theyd last forever.

 

If I'm taking the engine completely apart I'm going to replace a number of parts, including all bearings. Not to mention this surface will quite often leak due to a grove worn into the shaft from the tc seal.
30 minutes of searching and I couldnt find it, until 2 minutes AFTER I started this thread!
