To whom it may concern,
If I may, two questions:
In the middle of reassembling my chaincase (1975 Mk3) and noticed that in the factory manual there is an exploded diagram showing what appears to be a washer behind the large idler gear. The Andover drawings don't show one. I don't remember there being one when I dissassembled it, so I assume the Andover drawing is correct. Any thoughts as to which is correct?
The spindle for the smaller idler gear (the one inside the starter housing) is hollow on the end with the taper. The hollow also apperas to be threaded. Photographs and the diagrams seem to show a solid spindle. Do I have the correct spindle? If so, does the thread serve a particular purpose? Maybe to hold it during machining?
Thank you very much!

Interesting idea about an extractor bolt but unsure how one could get to it since the theaded hole is on the tapered end which was installed going into the inner cover. It would be covered up. Unless I had that installed the wrong way around. Does the tapered end of the spindle face in or out? Amazing ho so many little things seem to have gotten muddy over the years.

Tapered spindle end goes into the starter motor end plate - taper helps the starter locate easier when offered up.
The workshop manual figure C52 shows a washer behind the large gear but the parts list/AN site does not. I reckon the manual was written prior to production as the inner primary case is machined to hold the gear away from the inner face. One of my old cases has a bronze bush for the shaft at this point as the shaft must have worn the inner case.
Regarding the idler spindle, I can't see why it has a thread - probably change of plans but just left it there during production - Alan
