240 B23 crank pulleys; how to get orientation right?

[Forg]

So after bolting the front-end of the B23 back together mit shiny new chopper-wheel & CAS, I've realised I need to fit the cambelt-cover in order to get the degrees-before-TDC markings - I'm setting up the ECU from scratch, so need to adjust the dizzy (for sync signal) to the right spot, using a timing-light.

Thing is, from what I recall of earlier today, only the rearmost pulley has a keyway in it; all the rest, held on by 6 bolts, can therefore fit in 6 different rotations. I have NFI what the timing mark even looks like on that front pulley; how do I work out how it bolts on?

The timing mark is not on the very front pulley. Look for a small notch in the back one i think. Look closely.

this. The notch is on a back washer...

Thanks folks ... I'll check it out when the day's houseworkey-chores are done.

There are various marks on the edge of the pulley that are as pronounced as the one which I think is the timing-mark ... however, if i line-up the TDC mark on the camshaft (ie. which means the crank & dizzy-drive pulleys too), there's a mark on the pulley which lines-up at exactly zero against the 0 - 10 - 20 - 30 markings on the cambelt-cover.

That's going to be it, isn't it, given where it is?

I think I might liquid-paper it or some-such, if that's it.

To try and describe the problem, here's an MS-Paint image which will probably just confuse it:

The situation, when the engine is turned-off, is as shown above.
To the left is the position of all the marks on all the pulleys; all are at the TDC position.
To the right, there are unfortunately lots of chips-or-whatever on the pulley you use with the timing-light ... however, there is one fairly prominent notch which lines-up next to the "0" on the cam-belt cover.

THIS is the notch which I should liquid-paper so it really stands out when using the timing-light to set the dizzy position; isn't it?

see post # * 5 * in the above thread...click on the "jpg link"
and you'll see a good scan of the marks YOU'RE dealing with...
once you have THAT sussed you can check the relationship with the
lower TIMING *COVER*....

Ta, but I'm past all of that ... the left-hand side of my diagram was supposed to indicate that all those marks are lined-up & that #1 is at TDC.

I was just looking for the mark on the "balancer" to highlight with white paint or similar so I can use it against the "lower timing cover" (well, on my car, the lower part of the timing-cover - the cover is all one piece) with a timing-light.

However ... since I started typing this I've had confirmation elsewhere that it is the right mark; so ta for the help!
