Hello everybody, my T236-engine for my Candian Dodge is nearly ready. But as always on the last mile unknown problems are popping up. Here is my one: Usually there are 8 studs at the rear end of the crankshaft to fix the flywheel. The part number of the studs is CC871685 (7/16-20 with a special head). They are always the same, in the 23-inch-engine as well as in the 25"-engine and they are mounted with a kind of clamp connection - I hope that is the right word.
So I bought a set of 8, because that barn find engine I'm reconstituting they where missing. But my holes are bigger! The diameter is somewhere between 7/16" [11,11mm] and 1/2" [12,7 mm] - or in our European measurement around 11,8 mm.
Is that a common mistake after so many years? I could use self made studs and fix them on the engine side with a nut. But to cut 8 holes in the crankshaft with a 1/2 thread seems to be too big, I could cut a 12 mm thread with a thread pitch like UNF.
Does anybody has a better solution?
And an additional hint for other enthusiasts: The NOS "flathead oil pans" for the 237/251 engines which are sold for 95 $ from Vintage Power Wagons don't fit on the T236 engine. The length is okay, but in the area where the oil strainer assembly is, they are too narrow. I bought one, it was shipped half around the world, sandblasted, carefully painted and now I can't use it. **** happens.
Regards
Jürgen
