Reassembly

The parts are were back from the machine shop last week and reassembly is proceeding at full tilt.  I found a machine shop, DG Machine, that I was comfortable with and the machinists and owner seemed like straight shooters.  When I toured the shop I saw they were working on an old two cylinder John Deere head so that helped with my decision.  I had them turn the crankshaft (took off 10 thousands), press and fit new bushings in the connecting rods, and rework the head.  On the head they milled the surface, replaced the valves, springs and guides and put new seats in for the exhaust valves.  It looked like all the work was done well.

Then it was time to start putting everything back together.  Dad came by a couple times to lend a hand which was great.  Here's a couple pics of the process:

 Overall the reassembly went well but I did have one oops.  I attached on the front cover that goes over the gears in the above picture as well as the distributor and the governor (with gaskets and gasket seal) and was preparing to put the crank pulley on.  To keep all the various parts and bolts organized they were placed in separate containers.  So I grab the container for the crank pulley parts and notice this 3 inch bowl shaped washer - oh no, where the hell does that go?  Inside the cover !?!  Sure enough everything had to come back off so the "oil flinger" could be installed.  If that's the biggest problem we have I think we're doing good.

Tomorrow will be the ultimate test.  Today I was able to get everything else installed (oil pump, oil pan, generator, manifold, carb, etc).  Tomorrow Dad is coming by again to give a hand reattaching the front wheel pedestal and finishing the reassembly.  Then we'll try and fire her up and see if she runs or try and figure out what we screwed up.  Hoping for the prior.

Snapped this today.  We have a couple chickens that refuse to stay in their pen and of course Morgan is fascinated by them.
