Seems like this might work as a rough check on staged assembly, but not sure what numbers to expect.

It IS discussed a bit ont nyet, but the context is generally US muscle cars, perhaps not directly comparable.

One "guideline" I've seen is 5 ftlbs for each rotating assembly, I've got the crankshaft and the three pistons in, which would put it at about 20 ftlbs at this stage. Torrential rain may prevent putting the head back on today.

Any guesses?

Really wouldn't worry about how many ftlbs it needs as long as it turns smoothly with no tight spots.

Thought it might help to decide whether the tight spot is tight enough to represent a problem. There is a point in the rotation noticably stiffer.

Academic though, cos It turns out I havnt got clearance for my (beam type) torque wrench anyway.
