XUD Brake Vacuum Pump

[Chlorate]

Hello again,

Some of you may remember that following my timing belt disaster, I discovered the Vac' pump on my ZX (direct drive from the cam) was a wee bit broken where it connects to the camshaft.

(I drew a beautiful solid model of said broken bit and posted it in a previous thread)

Just took a punt on a used one on ebay - £22 with postage

I'm wondering: since these things are pretty simple little vane pumps, is it heard of for them to go wrong? They seem to be pretty well built little bits of kit.

My broken one was fine until the mishap, had a mityvac on it a while back and it showed the right pressure etc. So even if it turns out the "new" one doesn't work could I possibly cannibalise it to fix the other?

Thanks

-Alex

i have seen a vaccum pump being the cause of a mashed cam shaft,

it is probaly not good practice to swap the internal bit from one pump to another,

I'd agree its probably not a good idea to swap internals from one to another.

Regarding failure, the only one I saw fail was the belt drive (early) one, as these have to be checked for oil level and of course no one ever had.

What happened next ?

So often the cause of the 'failure' of these pumps is a totally blocked exhaust port. I seem to recall it has a little filter in there...

I've renewed the o-rings on mine and an hour later was offered one for £20 free p&p from a 70000 mile engine, took the deal.

How many threads on here leave you wanting more .

My pump was very clean was just the o rings they were very flat and showing signs of perishing.
