The bushings are press-fit and then need to be align-reamed afterwards to the right dimentions... pretty sure Search will find you lots of discussion on this... including pictures of the specific reamer required.

You can check over at www.vwdieselparts.com as well for discussion... look for a thread with Fatmobile where he shows his custom case for the reamers. ;-)

I compared his bushing to the IP shaft and the bushing measured .001 (one thousandths) smaller than the shaft.
They would not slide over the shaft at all.

I have a set at home but being the space cadet I am I forgot to measure them last night for a comparison.

So anyway to add another level to his question.

What is the max specs on the IP shaft as to how much play it can have before you have to replace the bearings? Anyone?
I thought it was in the Bentley but we couldn't find it.

BTW, I did a search and came up with nothing relevant at all.

'82 Rabbit, I put on a euro vnt-15, 2.25" DP, 2.5" exhaust, the result.....it whistled.

I removed the turbo, made a toilet bowl 2.5" DP, the result....it was deafening. Now it has a homemade muffler up front and a thrush in the rear, the result.....less loud.

I did get a bore gauge but have been reaming them until the shaft fits tight but still spins with some oil.
 The last one jiggled a little,.. it was 1 thou on the outside bushing and .75 thou (.00075") on the inside bushing. Worked great on the car.

Push them away from the center.
 One goes inward and the other goes outward.
 According to a bosch sevice center guy from Zips diesel in St. Cloud, MN
 The local guy says it doesn't really matter but I still do it the way I was told to. I figure the local guy was just too lazy to do it right.
