Nice work. I'll have a go at mine at some point.

Just move down here Rob and we'll do it together! Photograph it along the way and put it all up on the forum. - and offer a rebuild service! . Probably a bit to cold for me to move up there!

Just think though Peter, you could probably buy a country estate up here if you sold up, complete with forest to keep the wood burner going. Then employ me as your lachie :D

Pressure side is working now. I had the outlet restrictor of the one-way valve upside down, so the solid face was blocked by the ball bearing on the pressure stroke instead of allowing fluid through the cross-cut flutes.

For anyone else attempting a repair, the assembly order of the pressure side from top to bottom is:

Overflow hose to top of tank
Black handled brass valve
Threaded union
Long banjo bolt
Dowty washer
Banjo splitter to gauge and pressure hose
Dowty washer
Long restrictor - cross cuts facing downward
Ball bearing
Pressure pump outlet
Pressure pump body
Pressure pump inlet
Ball bearing
Short restrictor - cross cuts facing upward
Dowty washer
Banjo on inlet hose from bottom of tank
Dowty washer
Short banjo bolt

Now all I need to do is fix the leaky Schraeder valve connectors at the other end of the hoses. I think the rubber grommets are replaceable so that shouldn't be too hard, and worst case equivalent parts are still available new.

Just noticed that my pump only has a single hose and the instruction plate designates it as a single hose pump. It also refers to an internal changeover valve, automatically switching between pressure and vacuum as opposed to switching hoses. Another complication to deal with.

Could anyone who has a two hose UK model pump possibly email me a good quality photo of the top instruction plate please?

Mine has no plate and the only one I can find online is for the single hose version. I want to try and get one printed up on plastic sheet to finish my refurb.

Email address is iwbarker at mac dot com

Thanks !

Thanks Trevor, that's exactly what I needed. I should be able to use it to create artwork for engraving a new plate at one of the online services.

Update: PDF and MSWord file of my recreated placard attached, in case anyone else needs one.

So is the twin hose pump the earlier version, later superseded by the single hose ?. I had never seen the twin hose style until now.
