I've still been working pretty regularly, .... trying for at least a little bit every day. The project I'm working on now is to add fresh water cooling to the 60 year old engines. I have no idea how they lasted as long as they did for raw water cooled salt water engines, but I'm not going to complain. Everything I've found on the engines seems to indicate they can still have some good life left in them (we'll really find out when she goes in the water next spring).
Some years ago I was given a pair of Sen-dure heat exchangers off a pair of Crusader engines that are in good condition that I thought should be big enough. A call to Sen-dure confirmed that they are plenty large enough. I then had to figure out where and how to install these V8 specific heat exchangers on my 60 year old flat head sixes.
Here is what I started with, ... a matched pair. They are combination heat exchangers/expansion tanks in one.
Before I could do much of anything I had to figure out how to drive a second water pump off each engine. The Chrysler Crown engines are designed with the water pump and generator gear driven off the cam shaft, so there are no V-belts or pulleys at all on the engines. ........ There is however this small stub on the front of the flywheel (for crank starting them, .......LOL Yea, ... good luck with that!!).
After a good bit of thinking I came up with the idea of making a custom 'stub shaft' that would slide over this stub and extend out enough to mount a pulley on.
I am lucky where I work to have free access to their machine shop, where I turned a matched pair of shafts.
That let me have some fun here.
And do a bit of turning and boring.
And cutting cutting on the Bridgeport milling machine to cut the key ways.
In the end I had a pair of stub shafts that I could mount some pulley on.
Here is the end result.
This should do the job.
Step one (of many) finished. That actually was a bit tedious as one engine had a crank stub that was pretty straight, the other one however had quite a taper to it, so I had to bore a matching taper on the inside of the adapter.
