Hi Ted

So you have got stuck into it.  Good for
you.  I have a busy schedule today but will reply tonight at more length
tonight.  I put a new timing chain on my 23 last week so it is pretty fresh
in my mind.  Karl

Subject: [HSS] 28 Hudson timing chain
& water pump

Hello out there - particularly Karl & Geoff-
This is in reference to
the previous articles I've posted about the
carburetor heat control on my
Dad's '28.
Please refer to the photos section and see the ones I've posted
with
a title similar to the subject above.
As you can tell, I've
recently torn into the front end of the car and
removed the parts for
repair/replacement.
I need to ask for your expertise to answer a few
questions.
In photos 1 & 2, you can see the slack in the chain. I have
the
tension on opposite sides from 1 to 2 to show the chain it it's worst

case in each shot. Looks pretty loose to me...
My question concerns
photo 2; What is the proper alignment of the
timing marks when I go to
reassemble?
In photo 3 I've circled a pressed-in pin, which I'm guessing is

another timing Mark(?) I didn't see it until the parts were
removed.
Does anyone know the timing spec? I've photographed the positions
of
the sprockets and the distributor rotor, but of course I can't be

sure that's going to be close enough.
Another concern is that it was
VERY difficult to get the water pump
out of the bore. I oiled it up well,
but still had to use a rubber
mallet at the front of the shaft to get it
to slide rearward. It
wouldn't rotate at all, not even with the tools
pictured. Did I miss
a step or something? I don't understand why it was so
tight. I'm
wondering if I'm going to have to take some emery cloth to the

surfaces so it will fit properly.
I'm also questioning the front seal,
as shown in photo 8. It looks to
me like someone spotwelded a piece in to
adapt a non-original type
seal into it. This wasn't how it's supposed to
look is it?
One last concern (for now!)is the wear on the oil pump lifter,

or "puck", or whatever the term is. It's actually about 1 - 2mm deep.

Is that enough to cause trouble?
We're sending the water pump out for a
rebuild tomorrow, where the
new style seals will be installed. I'm going
to call him soon after
he gets it to ask if he splits the shaft (like karl
did with his) for
easier future removal of the pump. Karl, I may need to
take you up on
your offer on the parts.
Anyway, I've obviously got a
lot of work to do on it yet. If someone
can fill me in on the questions
above, I'd appreciate it very much.
Sincerely,
Ted
