I know this is older but I have a question about the water pump drive gear. Is it suppose to have that grove in there like that? I thought I saw some that were all flat with out the grove. ( talking about the grove ring on the silver piece in that picture )

The seal surface area is completely flat and smooth on a new drive. Any groove is caused by wear from the seal. I think that picture show more of a shiny area that might look like a groove, but perhaps there is a little wear.

Ok thanks, as my motor sits now and the drive gear is out mine does have a grove, and i was trying to figure out if i need to geta new one. I'm guessing I will have to pick one up then since we figured the grove was worn in. ( the rubber gasket was hard )
