I'm just reviewing the Bentley getting ready to re-try getting that 86 transmission on the 1.9 engine later today. Fig 1 on page 30.6 talks about marking position of pressure plate on flywheel before removing. Oops, I didn't when I took it off yesterday to examine whether we'd damaged the clutch disk splines in our previous attempts. Is this a big problem? I can't see how the its rotational position on the flywheel matters but, if it does, I'd rather not learn why the hard way.
