  1. My crankshaft gear was badly pitted too, and when I got a parts engine with better gear I swapped them.  I figured the crank nut might be torqued pretty tight, so in order to get it loose without twisting the crank I made a wood block clamp to grab the main journal just behind the gear.  The block was bolted through a piece of plywood and weighted down further with the second crank.  (those things are heavy!)  A  box end wrench on the nut protruded over the workbench.  I whacked it with a 3' length of lumber and the nut was loose.   Then the gear could be removed with a puller.

  2. I went through this same task on my 1948 Chevrolet.  Every signal manufacturer uses a different wire color code scheme.  Below is what I found online for SignalStat900.  You will have to figure out what make and model you have and search online for correct wire diagram.

  3. When I worked for a vacuum metalization shop back in 2001, the big machines that did production lots looked like this photo, with vacuum chamber around 4' diameter.  I was designing tooling for new products and figuring how many parts could fit on a tool so the company salesman could provide quotes for potential new customers.  My boss told me that our machines had been used by automotive suppliers back in the 1960s & 1970s to plate plastic parts.  There was a small machine around 2' diameter that he used for 1 off or very small lots that some customers needed for test purposes.  I have no idea what the charge was for a small lot.   We never had to deal with a customer order that required stripping old plating, but if we had to, the same tank of acid that was used to strip off all the excess build up of plating from the tooling could also be used to strip plating from a part.  But if there were any metal inserts or clips attached those would disappear in the acid bath.  This shop had operated for many years as a small operation that also included painting and e-dag coating, and probably could have survived the downturn in electronics industry that occurred in late 2001, but they had been bought out by a corporate group with no experience in manufacturing that made too many mistakes and it all closed down.

  4. After a long cold winter it finally warmed up enough to prime the rear wheels last week.   I installed modern lip seals instead of the original felt seals, and added a few dabs of rtv seal to keep them from spinning.  The old seal retainer is reinstalled to keep them seated.   When I looked at the NOS 1310 bearings I purchased earlier, one is New Departure, identical to the old bearings, the other is Federal which has 8 balls instead of 12 as New Departure uses.  As far as I know there is no difference in bearing rating based on number of balls.   They are pretty much overkill for passenger cars anyway.  I cleaned up the 2 old bearings that came out of the wheels and to my surprise, they both appear to be as tight as the NOS ND bearing.   I have reused old bearings in other locations if they are still tight, and am considering reusing one of the old ND bearings and the new one.  There is a a little primer overspray on the old ND bearings that is making them look dark.   Any opinions on 8 ball vs 12 ball bearings, NOS vs good condition old bearings ?
