I got a new drive gear and after installing it in the drive gear
bearing I have .032 gap between the drive gear bearing and
the drive gear sleeve, this seems like way to much. The old gear
had .016 end play and I checked a couple others I have and they
are .017 to .019. Anybody know what the end play should be?

The parts you are working with is the "oil pump drive gear assembly". You have installed a new oil pump drive gear in your drive gear housing. When you installed the drive gear sleeve you have .032 end play.
Did you install a new sleeve? If you re-installed the old sleeve it may be worn. You could try using thrust washers to take up the space. Make sure they are thrust washers not just plane washers. ( You may know this but there are other people reading it)
 
Thanks for the reply redmodelt. I know the problem is the new gear as
the other three I tried only had half the play. After looking at how it all works
I see the rotation of the cam is going to pull the drive gear down in operation
and so I don't think there will be a problem with the gear bouncing up and down.
