Climax small domestic pump

When I restored this one it never had any evidence of what model or make it is other than it looks like a Climax


This Climax is clearly identified but it is probably barely half the size of the other but unless viewed side by side it is not obvious. I have two of these so all the best parts will go into one.

I had one of those smaller Climax pumps that I bought from the late Percy Gallamore (Blue Cats father) and ran for 20+ years before I sold it on. I never had to do anything at it apart from at Lincoln rally one year when I used water from the plastic barrels they supply and tiny plastic shavings became wedged in the valves! Easily sorted though, and a lesson learned.

Nice one, at least it came apart. The last 2 Stuart pumps I've had have been been PITA to get apart.

Hi Andy, I had one like that on a LISTER D https://youtu.be/yeVtggTHxYI

Looks marvellous

Today I've stripped cleaned and reassembled the drive end.

I don't understand how the big opening on top of the pump body is meant to be used. Seems to be to add lubricant but you just can't keep adding oil? beyond the oil level of the filler plug.

EDIT
I've just had a thought that it must be to release pressure created by the piston in each direction and allow expelled oil to drain back in.

So the wet end


Parts missing here namely springs and washers






Tomorrow I'm going to make a tool for removing the brass caps. I plan to use a 16mm bolt and reduce the 24mm hex head to fit.

I thought that the pumps may have been designed with a mounting for an electric motor, similar to the Lister domestic pump! Or maybe to put some kind of packing in there for keeping the piston lubricated!  I made an alloy plate to go on mine, not a tight fit but tight enough to stop any crud going in.

The picture I've seen of a Climax with an electric motor shows it renders the hole in the top inaccessible so IMHO its as I said and relieves air pressure from the piston moving too & fro.

A 14mm bolt has a 22mm hex head and this fits the brass caps. So I welded a nut on the thread to use it as a tool. Despite this it still needed huge leverage.







Fortunately a second pump I have has the correct valve parts


After cleaning


As they should look

One thing I discovered today is that the valve caps are 1 1/8" BSP how strange and non conformist is that?

Its a good job I have two pumps to draw parts from because I lost this. I can only assume it got knocked off the bench into the bin and bin day was yesterday

Anyway so far I've taken most parts from the other pump including all four valve springs.

The wet end piston parts were also better from pump 2
I've ordered 1.1/4" leather cups



As an upgrade to the lost part I fitted a rubber grommet


Time to start thinking about paint while I await parts.

That's coming on a treat, going to look awesome when it's finished!
The picture with the Petter and bigger climax pump, where did you get the sliding base for adjustment on the belt, or was it something you made?

Thank you for that! Just had a look and not as dear as I thought, you probably couldn't make it for much less than those prices!

Can you remember what size your base was?

Won't help you unless your pump is the one I used which is very much bigger than this Climax


45kg compared to the current one about 20kg

I have 2 of the same pump as per picture.

perfect thank you!

A little time on the lathe and buffer has made a respectable job of this cap. The other still needs a bit more effort but will be ok

I decided to improve on my homemade tool.






I have a cap for spare too


The colour is going to be Belle Mixer Orange, as iconic as JCB yellow, John Deere Green and Massey Ferguson red.

Awesome, certainly won't lose that in a crowd! Should look lovely.

Thanks

I've just made a cover for the top to fit as a motor mounting plate would. It's made from 6mm paxolin so won't rust or degrade and painted it will look like metal.

A good fit

A piece of 6mm thick rubber enough to cut five valve discs £2.30 delivered.


The 1.1/4" wet end piston cups arrived, I just need to drill them out to 16mm.
