the torque plate bolts are the same as the flywheel bolts on all
vanagons these are
6 point socket heads bolts. the early type 2 engines origninaly came
with a 12 point bolt for the torque plate. I paid $ 10 each for the 12
point bolts last time I ordered them. the differance as far as I can
tell is that the 6 point bolts protrude just slightly from the torque
plate.
        my consern was that the bolts would keep the converter from sitting
flat on the plate.all automatic vanagons engines that I have torn down
have come with the 6 point bolts. automatic busses and van use the same
torque plate and torque converter so go figure. the newest bentley book
lists 2 differant torque specs for the the torque plate depending on the
year 65 ft pds up to 1985 and 81 ft pds after 1985.
 the flywheel has 2 torque specs depending on the how old the manual you
are using. the newest bentley lists a torque spec of 44 ft pds and a 1/4
turn and the older books have a spec of 80 ft pds this applys to all
type 2 and was the orignal spec for the vanagons.

        80 pds is the spec I use on all type 2 and vanagon torque plates and
flywheels  and yes I do reuse the bolts with no loctite when they are
not to beat up as some times happens when removed
Greg from Gregs repair confirmed this as the proper method he added that
the 3 bolts that fasten the converter to the torque plate are more often
the problem
he pointed out that they are grade 12.9 a very hard bolt and he felt
that the torque spec of 15 ft pds was inadequate 20 ft pds would be a
minimum with loctite remember that they are threaded into steel not
aluminum
Bentley gets its info from VW and passes it along without passing
jugdement they have told me they do not feel free to modify thats been
handed to them without a tech bulletin to back it up even when I have
proven to them that there is a better way

there should be no question that I am a pain in Bentleys collective butt
they know me by name
