Std Thrust = .865 >> Flange width= .100 for Std /+040

#1 Thrust = .825 >> Flange width = .140 for +020/040 

#2 Thrust = .785 >> Flange width = .175 for +060/080

Crank End Play = .003" to .006"

Main Bearing Clearance = .001" to .007"

Rod Clearance = .0008 / .006"------------ Cam Bore = 1.0825" to 1.0834 

Rod Side Max = .004 / .028"------------ Lifter Bores = .7480 / .7488

Piston Clear = .0015 /.008" ------------ Ring End Gap = .012 / .035"

85.5 mm Bore dia. = 3.360"............ Ring Side Clearance =.0047

  Note: The "Ring side clearance" in the piston grove will tell you if the piston and cylinders need replacing. there is no need to mike the Piston and Cylinder when working on the VW. When the side clearance is over .005/.006 it's time to replace the P&C Kit.
                   
Volkswagen gives the maximum side clearance as .0049"
