A question of finish

[richardACS]

1965 1275 S

would the following have been at this stage of production painted engine green or electro plated:

Clutch slave?
Pushrod for the above?
Spring plate?
Clevis pin for above?
Return spring for above?
Oil pressure pipe to gauge ?

Wiper motor casing - dark grey hammered finish? where to obtain some?

The 6 little hexhead screws to attach the fan guard to the radiator - did they have a washer or just a direct contact with the guard?

Where to get a repair kit for the brake servo - (original type to this year of production)

Thanks in advance...

No washer on rad screws. Try Alfa Romeo for servo kit.

[Peter Laidler]

There's the dilemma......
Workshop practice tells us that you SHOULD have washers on those types of fixings
Same as push-rid, spring hanger and clevis pin - and split pin. Painted. But engineering principles tell me UN-painted
Wiper motor casing, there was a black and mottled silver variants so far as I am aware

Go with your head - or your soul I say Richard

I would plate those clutch related items, get it assembled and adjusted / working, then a tiny splash of paint in situ.

To the best of my knowledge, based on helping my dad in his garage mostly (late 60s) and of course, many scrapyard trawls:


Clutch slave? Painted with engine (I recall seeing paint on the rubber seal cover too).
Pushrod for the above? Painted where visible
Spring plate? Zinc as fitted later
Clevis pin for above? Natural Metal
Return spring for above? Unpainted
Oil pressure pipe to gauge ? Unpainted

Wiper motor casing - dark grey hammered finish? where to obtain some? The Hammerite version is remarkably close. It often looks darker in pictures than the original paint on my wife's car. You can see the remains of the genuine silver colour on the bottom corner of the motor in the enclosed pic.

Thank you all for your replies - very helpful.

Is that a wolf in sheeps clothing Andy?

I use this for the motor casings, more accurate than the Hammerite

Black crackle, it seems was only used on factory reconditioned units.

Well spotted, when the old engine died it got a gold seal 970S replacement - tweaked a bit too. We got the car in '78 and it has just been kept going over the years - we love it

Andrew's paint looks interesting? I just used hammerite as when I painted a sample on a card and compared it to the corner, it looked pretty close. Knowing Andrew his is spot on

Thank you Andrew, I couldn't find a dark grey hammerite, will order a can...

That's a proper wolf with maturity.

Good idea and double protection...thanks

Paint and repair kit ordered - thanks for reducing my search time

One more question please on the servo finish - the cast iron nose section appears to be unfinished steel although some say it should be black?

The 'bellow can' is often seen in yellow passivated zinc, although elsewhere it's mentioned as being cadmium with blue tint as in clear or sometimes bluish passivate - any thoughts for a 65 S?

[Peter Laidler]

Mine had a black nose and the can was a distinctive yellowy/goldy zinc type finish. I had it finished in oven baked nylon that turned out to be a bit more goldy than I wanted. But hey-ho

The servo body ought to be a dull black finish. The vacuum chambers were cad plated yet this is no longer allowed due to healt and safety reasons, hence they are usually zinc plated.

Here's my nos one as an example:

Thank you Peter and Toby....

I note that Frost do this:

and kits:

I've also used this in the past with surprising good results - but on a Ford not a mini.

Interesting, do you have any pics of the finish?

It is on my RS500 and no one has ever commented, I did take pics but will take some more

[Costafortune]

You can clean and Scotchbrite parts like this and then paint them in a clear lacquer with a dulling agent for a satin finish. Stuff retains its finish for yonks.
