Heater valve operation

[spinninghoop]

Hello all,

The heater valve on our new traveller is not conneted to the control cable, is located at the rear of the cylinder head and is seized. What is the operating sweep of the control lever? It is at about 12 o'clock now and must be partially open beause there is some heat in the hose. Does the cable attach to the lever and just act on the sleeve at the control knob end or does it act against a bracket on the engine or bulkhead that is missing? Presumably the cable attaches to the lever with the same type of cross-drilled pin as a throttle cable? (also missing). Many thanks.

OK, this is going to be tricky without a picture but maybe someone else could oblige there...
If I remember correctly the outer of the cable is clamped to the bracket part at the top of the valve using a P-shaped clamp and small screw. The inner goes to the lever using a cross-drilled pin through one of the holes. There's a picure here:

(though this picture is confusingly rotated 90 degrees)

From 'on' to 'off' is probably only 1/2 inch or so, 12 o'clock to 1 o'clock...?

You'll probably get away with a small dribble through the heater for now, but replace it before the winter unless you want to freeze. A fully working heater is barely adequate as it is!

Thanks,

It seems that it is of another type, not the plunger one. It is more of a solid brass bar lever opening a solid brass ball valve, very simple. Must be of an older type? Anyone ever seen one?

[Cam]

Yes, that's the earlier type. I have one fitted to my '52 MM and my '63.

Trouble is that you need to stop the car, get out and turn the wheel to shut the heat off!!!

[spinninghoop]

Cam, it's not the handwheel type either, and doesn't look like a lever has been added where the wheel was. Is there anyway I can upload a picture for general perusal and chin scratching?

[bigginger]

You need to host it somewhere and then link to it - if you want me to post it, email it to me at REMOVED (a)

I had a similar type on my 1098 engine, had no idea where it came
from. it had a brass body and a flat lever about two inches long
which was swung from upright to horizontal to open the valve.
It seized solid! so I have fitted a nice new brass bodied handwheel
type. Let's face it you dont have to turn it on and off very often
(twice a year in my case).

[bigginger]

There it is then. Anyone recognise it?

[rayofleamington]

I recognise it - as in I have seen that type before.
I've no idea what age or what car it comes from tho ;-)

[spinninghoop]

If I can't free it, is it a straight swap to the newer plunger type? Stud lengths and centres ok? Thanks

[Willie]

That is exactly the type which was on my car and yes, the proper
type will fit.( I donated mine to a museum)!!

If anyone wants one of these type look at this

You learn something new every day! I've got another mystery one on Bunny - must post some pics...

[spinninghoop]

The valve has now been changed for the cable operated type. Thanks to all, especially bigginger for hosting the picture and willie for the "like for like" info. Will post the valve on eBay as it freed off ok with a WD soaking unless any of you guys want it.

[bigginger]

Aw shucks, it was nothing...

I recognise it - as in I have seen that type before.

I think you will find that the correct application for this type of water tap is the MK1 mini van and they are quite thin on the ground.
So spinninghoop I suggest you put it up on ebay and get a few quid for it.
