Preparing the Crankcases


This, as all you classic motorcycle fans will know, is a sump plate. It is extremely nasty - it is pitted, bent, and is about as flat as the surface of the moon.

I'm afraid it has to go in the bin, to be replaced by one of Drag's excellent new ones complete with drain plug and magnet. Theirs are flat, thicker and made of nice strong modern aluminium!
 
Here it is in place, trial fitted with the pick up pipe and the suction strainer. To the right of the timing side main bearing, you can see the riveted cover over the drain from the oil pressure relief valve.

 
You can also see in that picture that the oil pick up pipe bolt has been wire locked into place.
 
And unfortunately, that is where the picture record ends. My camera packed up, and now I have no record of actually assembling the cranks into the cases...
 

Until we get to here, which is just to record that I did close up those tab washers correctly! That's plumbers pipe cladding protecting the rods, by the way.

  3. I have a 1955 engine it does not have the riveted cover over the drain from the oil pressure relief valve or any sign of a drain there
