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"
