The New 2 Do

The Mrs. has been extremely patient. I've been off chasing butterflies with this bus for some months now, and she has silently endured a failure to complete a few 'niggling projects.' But we're about to leave for California in 56 hours (yes, I'm counting in hours) and I think it would do me good to clean up a few of those  outstanding matters before we go, that way she can come home to a house with them completed.

In the mean time, I need to make a long list of things to do on the Bus engine to prepare it for rebuilding. The list is not for the faint of heart. As I said earlier, this is blueprinting: Where none of the dimensions are assumed to be as they should be, so all must be measured.

• Acquire snap gages from HF
• Acquire Micrometers from MM
• Remove and number all of the crank and cam dowel pins, securing them in their own carriers.
• Scrupulously clean the mating surfaces of the case especially at the front and rear.
• Take case halves and reassemble them, empty, back together.
• Torque the case bolts to spec using Brownline TQ wrench.
• Cover the bore holes at the flywheel end.
• Using a strong light at the flywheel end, look down the length of the bore to see whether any light can be seen in gaps between the main webbings or mating surfaces when the case is fully torqued. Visible light at a mating surface automatically rejects the case.
• Using snap gages and micrometers (and less accurate calipers when impossible to use mic) measure and document the bore of each of the mainbearing saddles three times, at 90*, 210*, 320* and then take the average. If any of the measurements are further out than 1/10 of an inch, align bore on the crankshaft bores is indicated.
• Using snap gages and micrometers (and less accurate calipers when impossible to use mic) measure and document the bore of each of the camshaft saddles three times, at 90*, 210*, 320* and then take the average. If any of the measurements are further out than 1/10 of an inch, align bore on the cam bores is indicated.
• Use snap gages to measure the rest of the bores
• Using micrometers, record the thrust of the camshaft and crankshaft bore webbing.
• Inspect for fretting of the metal around the bearing bores
