Oil Pressure

How difficult is it to swap the bezel?

[smiffy]

Easy peasy. There are three small lugs on the bezel that fold over a lip on the casing. Ease these up with a small screwdriver sufficient to be able to twist the bezel relative to the case - it will be rather stiff to start with if it is an old gauge. Some cases have three slots let into the lip; lining the lugs up with the slots will allow the bezel to come free. If there are no slots in the case lip, you just need to bend the lugs up a bit further so that the bezel slips off the case. Be careful not to drop the glass, but usually it will be stuck to the bezel. Replacement is simple, just slip the bezel onto the case and press the lugs against the case lip.
Best wishes, David

Righto! - Thanks, that's next weekend's entertainment sorted. Just so happens I have a spare u/s original electric gauge to cannibalise and keep the working one for later use.

I had to change the engine a while back [1] and replaced it with an early Mk2 3.8 which had the upside down oil filter which the original gauge transmitter doesn't fit as it fouls the filter housing.

I've had a lashed up ex-Mini mechanical oil gauge arrangement under the dash. If I change the bezel I can fit it in place of the electric one (which obviously doesn't read anything).

I have plenty of flexible oil line so the occasional opening of the centre piece shouldn't cause any problems.

Pity the typeface on the 100 psi Mini gauge is slightly different:


However, can't be any worse than a non-reading one in the centre and having to peer under the dash (by the bonnet release) to see the working one.
