Hi

you only get two handles one permantly fits on the pump pointing downwards and the other shared between the clack valves as these are not normally shut off.

It's not advisable to have the handles on the clacks permanently as little Johnny can come along and turn them off. This is not a good idea as on the pump side a closed off clack will put a lot of strain on the hornplate as the pump works against an obstruction. It's also useful to file a line into the square shouldered head to indicate their condition i.e. a line at 90 deg to the boiler shows that they are open.

You therefore only need one handle on the water pump and the other can live in the tool box.

Clack valve handles

Post  Steve Traill on Fri 22 Jan 2010, 3:11 pm

Totally agree with Tim on this one, one engine I know (no names to protect the innocent) left the handle on and 'little Johny' turned it off and when the engine was being driven later & the water pump turned on there was a bang and he was left with a bent hornplate and a mangled waterpump bearing! Water is not in the least squishy so steel bends before water compresses.

I have filed out one to so it push fits the square but found the corners are very close to the edge of the brass and it has started to crack.

hmmmm.

the pump handle could be silver soldered on if they do start to crack but then it's on for good!

I'm not too fussed about the other handle I'll be using it as a spare for the pump as you'll never really need to shut the clacks off and a spanner is the best bet for this.

Hi Guys,

Not had chance to look at the handles yet but will do my best to tomorrow.

Assuming that they can't be opened out slightly, isn't it an option just to hand file the four flats on each of the stainless steel valve cocks and the water lifter bypass slightly smaller so they fit? This way it would leave sufficient wall thickness on the cast handle. Sounds like as it was lost wax cast they're has been a shrinkage problem.

Hi Guys

Sorry not been on for a bit . After all the INFO I went for the pins and filed them down.
I did try it on the engine at first but if I sliped then well you know .

So pulled them out and did it in the vice.

I think that this is a better way but what do you guys think??

I'm not at this stage quite yet but I'll comment on this one, is this shrinkage problem with the castings going to be rectified at all?

Hi Alan,

I've put a set together and really don't think that there is a problem. There is some shrinkage on the handle which makes the square in the handle the same size as the square on the cock. Under normal circumstances we'd ask customers to gently file out the square on the handle a little, the problem with this is it leaves the wall thickness too thin, therefore it is better to file the flats on the cock to suit. That's what i did and it really was a two minute job with no more than a flat file.

Hope that helps.

Hi Lilyjack

As you can see I filed down the vavles .You can try a big hammer but it may not work. Sad

Yes this is the best way to do it.. I threw one of mine away, by opening out the brass casting just made it split at the corners.. i've filed my square on the valve on the pump and got the other one to fit now..
Very Happy
Thanks

Hi Dean,

If thats not too much trouble that would be good. just to have a spare for the pump really just in case.

I will probably just use a spanner on the clack valves if I need to close them at any point. I have the one on my pump fitted so thats the main one that I need.

I'll be sending back the spare outer diff bevels you sent me to try out over the next week or so i'm just finalising my gears at the moment fitment wise. I ended up using the outer diff that had not had the teeth made smaller. I found that it meshed nicely with my drive gear so I'll be using it..

I'll send you a mail once I have sent them back to you..

Cheers
Jo
