That is the correct place for the locking tab Pt No: 6K831 (BMC).

Tighten the two bolts to 9lbf ft and secure the tabs.

Note:- If you are fitting a duplex chain the locking tab and bolts are discarded and the holes in the front plate countersunk and countersunk Allen screws fitted & Loctited in place.

Looking at your picture mits, make sure the triangular plate has the soft bearing face against the cam, I'm pretty sure, from memory, although not positive, it can be reversed.

thanks for that philthehill and the views bril

and les i have done that also does the little hole go to the left as i have it?

I'm not sure where the hole would end up, although looking at the exploded views it shows it in the position you have it. The important point is getting the correct bearing face against the end of the camshaft. If in doubt you can scratch and mark the bearing face but not the other face, do it very lightly though, towards the edge to avoid harm.

ok les ive looked at it and shiny side is facing cam so should be ok.
thanks.
they may be more to come on this rebuild lol

The hole in the camshaft thrust plate is in its correct place.
The hole is there to allow oil to pass from the bearing to the timing chain.
If there is any fore and aft wear (0.003" min - 0,007" max) the plate should be replaced.
Personally I would replace the plate as a matter of course.

If I remember right the hole ends up where you have it, inner most and towards the top, which means you have the plate the correct way round. That's how mine is fitted, and where the old one was on strip down.

great thanks fellas
ok another one in my head set i have 8 tiny 0 rings are they for the valve stems and do you just remove the collets and drop one on the valve stem then replace collects?

Tony
Absolutely correct - they go at the bottom of the valve collet groove but they are next to useless in preventing oil from going down the valve stems especially the inlet valve stems.
The better way of fitting oil seals is to use the later top hat seals but ideally they should only be fitted to the inlet valve guides which have the location groove. The top hat seals can be left off the exhaust valve guides as the exhaust valve stems need the oil for lubrication.

Hi ok just refitting the distributor now when i stripped it i cannot remember wether there is supposed to be a gasket between the clamping plate and the engine can anyone enlighten me please ?
Tony.

[biomed32uk]

No there is no gasket, should be an O ring / seal on the distributor where it fits into the block.

O-Ring Ø 23 mm x 2.0 mm

The 'O' ring (Pt No: 13H2792 (MOSS)) was only fitted to the later 'A' Series distributer housing.

The housing has to have the groove machined into it to enable the 'O' ring to be fitted. If no groove no 'O' ring can be fitted.

The 'o' ring was fitted to stop oil under crankcase pressure working its way past the distributer housing and out onto the outside of the engine block.

There is no gasket fitted between the distributer housing and the block. Sealing in this area without the 'O' ring relies on good machining/good fit.
