Looking for a good 100 crankshaft

[Michael Oritt]

My engine rebuilder reports that the magnafluxing of the crankshaft revealed some cracks and I wonder if anyone has a good (as in not cracked) 100 crank lying about their shop. Respectfully I am not interested in hearing about how I might get by with the cracks or how I could have the crank repaired.

This is your best source, > Marine Crankshaft, Inc. < . Richard Mayer just got this new 100 crank from David at Marine Crank, it's a beautiful piece of engineering.

Dougie--

Fortunately I have been able to locate a good stock crank, which is really all I need since my 100 is a street car. It is being "re-cracktested" prior to shipping and I will report back on final results.

I am currently having a good amount of work done on my 100 at "Proper Noise," a restoration shop just outside Reading, PA. Among other things, I requested that the engine be torn down as it had been about 90,000 miles since it was overhauled in 2003.

Beyond the usual "wear items" I expected to replace, magnafluxing of the (original) crankshaft revealed that it was cracked. While not surprising, this was nevertheless disappointing as I feared I would not be able to find a good stock crank in a timely fashion and that I might have to buy a DW billet crank, which apparently also involves buying forged rods that are either required or strongly recommended to go along with it.

Back in 2003 I installed a DW "fast road camshaft" along with an AL cylinder head and tubular headers, but since I observe a 5500 rpm redline and do not race the car, I felt I was going to be spending big bucks for competition-level parts on a street car that is perhaps "semi-vigorously driven," at most.

I put out a message on the autox list as well as the 100 forum asking if anyone had a good crank and I got several responses from folks who had cranks that had not been crack-tested but I found no likely candidates "this side of the pond." I was naturally skeptical of any untested cranks; after all, unless someone were building up a race engine why would someone replace a 100 crankshaft except that it was cracked?

Then I received a message from Michael Salter - a known and trusted source with whom I have previously done business - saying that he had two cranks on hand which had been crack-tested. This was great news and we made arrangements to have them retested, which turned out well, and I am happy to say that less than three weeks after learning my old crank was cracked I was able to purchase a suitable replacement for a reasonable amount. As far as I know, Michael still has the second crank so if anyone is in need I suggest you reach out to him at michael.salter@gmail.com.

BTW, I am installing an AH Spares damper on the crank - perhaps not required but, I think, money well spent.
