The
tab
and shim washers
may
be discarded where they were once used
on
earlier models, but the bolts
must be tightened
to
the torque specification indicated.
All
threads used, except those used
to
manufacture the basic engine, are
of
the Unified Series and American
Pipe Series. The crankshaft and the
pulley retaining bolts are threaded 5/8- inch Unified National Fine (U.N.F.
18 threads per inch).
