"A"= Outside Bearing Dia. ... "B"= Bearing Thrust Flange Next to Flywheel.
"C"= Inner Bearing Flange = .100" This Dimension should never be changed.
"D"= Crank Diameter...."E"= Stock Flange Dia.=2.820" / Max. Dia of Bearing in Case=2.900"
Some Oversize Bearing flange dia.
(E) will need to be cut or cut case to fit.
"F"= Thrust Dimension of Case.....Std=.865".....+1=.825".....+2=.786"
Note: Cut Case Thrust just to clean up & then cut bearing to fit case. Never cut case to +1 or +2
thrust.
If Your shop tells they cut the thrust to a #1 or #2 so it's easer for
you to buy bearings. Find another VW Shop fast.

*** Very Important: When Grinding the VW
Crank the radius must be .080"/.100"
. . . .Most Local Crank Grinders will not redress
there grinding wheel for this large radius.
