  Patrick,  your engine mount is tack welded together, looks good   and is
  out of the fixture.   Here are some photos.    I included two of   the
  digital protractor showing the fixture is  dead on.  I know I am
  bragging  but it was a big deal here.    It made my day!!

  Did I mention that you should install thread inserts in the pan   bolt
   holes that are in the aluminum housings.  The irons should be   checked
  but they are probably o.k.   Either HeliCoil or Time Serts are   fine.  It
  is something to do  while waiting for the engine mount.

   More later,   Jerry

  p.s.  Paul, I have published so many pictures of S-beam engine   mounts,
  I don't know if  you want to publish more or not.   As  you   wish.   BTW,
   I think this engine mount  design is the the best yet.  It is a
  pleasure to work on.


  Looks great Jerry.

Jerry / Paul,

What size helicoils should we install?

Thanks,
--Kenny A.

six mm but I don't really think you are going to get into
the aluminum rotor housings. The cast iron end housings does not
need them.

Paul,  that reply does not make sense.  I think you left a word or two
out:).  Anyway Kenny,  use inserts on the aluminum housings- the irons
probably will not need them.  Jerry


I don't follow you Jerry. The S- beam is not wide enough to need
the rotor housings bolts. Only the end housing.

There is no load on the oil pan to speak of.

Here is one of your Zenith mount  pictures showing the bolts.

What am I missing?

Kinda what I thought. Looks like all the S-beam bolts carry into the
iron end housing; am I wrong? Paul's point is that since none of them
are going into Al, there's little point in HeliCoils. Any oil pan
bolts not attaching through the S-beam are lightly loaded (force
evenly spread).


--Kenny A.

You are correct Kenny. Unless of course Jerry added a couple inches
to the width of the beam.
