While I contemplate my favorite job (de-greasing) in this case the steering box, I decided to work on the front windscreen. Some of the screws came out with the impact driver, using a hammer and the impact bit some backed out nicely. A few broke and others would not budge. I had to resort to screw extraction. Drill out with a bit going clock-wise, hand remove the screw with the extractor going counter-clock-wise. I'm not sure what the fall out will be when it comes time to re-thread new screws, but I'll deal with that later. I finally got the upper and lower half separated and most of the hardware off. I still have one brace screw to remove, but I'll get to that soon. For now the glass is out. I can blast and do some minor repair on the small lower channel rust areas.

I spent a little time on the fuel tank. I removed the other baffle so i could completely clean the tank. I will try sand blasting the exterior as the metal is not weak or rusted through any where. The crud on the inside is sediment and it scrapes off very easily. I hope to build two new baffles, weld them in and then following a few other's threads, coat my tank and add the top. I still have a bit of reading to do before I decide exactly how to tackle the whole process. Any recommendations will be gladly received.

I'm not sure how to tackle the center bottom drain plug as it is all buggered up and not salvageable.

I suppose one could debate the logic of removing ALL of the screws. I was thinking if I left them in they would only get worse with time. This way I can arrest any corrosion, treat them, replace and hopefully provide more years of trouble free life AND an ability to take the screws out without all this Arsch pain. :o

Machine shop finished the valves, guides and seats today. Will perhaps work on the cam on Tue or Wed. More to follow.

In retrospect, all of this machine work, new pistons, guides, bearings, etc are all a necessary part of ensuring the longevity of this engine. I suspect it will fall into the hands of a collector/enthusiast and the overall wear and tear to the engine by the new owner would be minimal, as will be the abuse. Given the nature of the engine rebuild, and the depth of the restoration, it should last another 50 years and 50,000 miles. I am glad that I am digging into every component of the WC. I cannot imagine doing another restoration with any less detail. The closer I get to the end of this, the more excited I am about starting my VEP GPW. given that all of it's parts are nearly half as big and heavy as the WC's, it should be much more manageable in the workshop.

The machine shop is working on the crank shaft today. They set up the stone with the correct radius for the mains, then ground the journals ro a true roundness followed by taking them to the correct 0.030" under for the mains and 0.020" for the rods. Here are some shots of parts of the process. I'll get a vid linked together and posted soon.

Thanks for the encouragement! Things are a bit slow lately. Both sons home from college, family and church activities abound and a bit of time for me to unwind. That is fine by me as its more important as I know you all agree...priorities. I'll probably be back in full swing in a week or so as the engine and cab are nearly ready for pick up. Then the fun begins.

Finished cleaning and assembling the steering box. For NOS it needed a lot of attention.
1. I cleaned everything out, lubed the rollers and contact surfaces and assembled everything back together.
2. I had to press out the sector shaft as it was "gooed" together and there was a lot of friction. I polished it up and lightly honed the two bushings so that the shaft slipped in with just a bit of friction.
3. Following Joe's advice I made a new gasket using the diameter of the wheel nut socket as my outer radius. I cut the inner radius to match the gasket pocket. I used permatex on both sides of the gasket.
4. I laid out all of the parts for the worm gear, I greased up the rollers and contact parts, installed them in order including the original shims and gaskets. I then snugged the bolts down checking for freedom of the worm gear to rotate without more than 0.010" end play.
5. I installed the sector shaft and the cover, and tightened all of the bolts. I used a 1/2" socket to lightly tap the adjustment nut into position
6. In stead of using the cork gasket, ring and spring, I used the rubber oil seal that I mentioned earlier as advised by Joe. Fits perfectly and should seal nicely.
7. I ran a length of stiff wire through the shaft from the bottom to make feeding the horn wire smoother. The horn wire has to be run from the top because of the soldered nub. The problem is that when you snake it through the shaft, it will run into the lip of the grease retainer tube and make it difficult to get it all of the way down. I can tape the horn wire to my red wire and pull it through.
8. Finally mounted it to get the parts out of the way. When the cab is ready, I'll remove it to make that job easier. For now its in it's proper position on the frame and everything fits and rotates freely.

With a little time on my hands i began to tear down the transmission. I removed the PTO, the levers, the brake band and started cleaning the exterior by removing the caked on goop. I need a larger socket to remove the pinion shaft nut. I will have to measure it as 1 1/4" is not large enough. Not sure how I got the others off, perhaps I need to look under my cabinets and tool boxes for the MIA socket. It's a big mess and it will take a while for the basic cleaning.
