engine plug at crank

Gentlemen, thank you for your reponses. It makes more sense now. It's not what I expected, but it does make sense and I guess it obviously does work.
Thank you.

engine plug at crank

By all accounts I appear to have the correct engine plug (part #0400.49.090) that goes in the flywheel/clutch cover. My question is this: even with the correct crush washer installed, how does this NOT cover the essential oil galley that comes from the oil pump and goes to the crank pin? It appears ...

750 GT Timing Marks

Ok, I found the australian club's website that confirms-the roundcase motors will not the vertical cylinder at TDC when the dots line up. It will be about 10 degrees BTDC. I believe the square case motors will in fact be at actual TDC when the dots align.
Thank you all for your input.

750 GT timing Marks

Craig, thanks for the response. I think I may not be making myself clear. As I understand it, upon correct assembly and the dots are lined up, the vertical cylinder will be at TDC. Let's not even talk about the cams, let's strictly talk about the dot on the bevel grear that slides onto the crank and ...

By the way, I thought maybe the associated woodruff key may have sheared and changed the crank to cam timing, but it's still in good shape.

sludge traps

The traps and plugs I'm refering to are not on the side of the crank webs, but rather on the edges. Rotating the crank makes them easily accessable through one of the cylinder openings. Mine did not have any punch marks to hold them in place.

With the cylinders off, I found this to be easy. Just to make sure I would not tear up the plugs, I applied a little heat and hit the plugs with a hammer impact (not too hard). They came right out. I'm glad I cleaned them as there was a significant amount of crap in there. It was easy to make sure ...
