Removing stubborn pump

Unread postby dinnerstick » Tue Mar 11, 2014 7:26 am

My pump doesn't want to come off. I can easily remove the whole pump assembly from the bottom of the kettle, ie. with the two elbows, but i can't get the pump apart. I don't own a wrench that big, but it is usually hand tight. Any known tricks or suggestions to loosen this stubborn pump?

I don't know if you do any car diy but I have a rubber strap to help me get oil filters off, that may help you turn the ring without marking it ?

Did you try giving it a few gentle "ticks" with a hammer? Use a piece of cloth to get better grip on the ring...

From memory I think Speidel recommend a piece of wood and a gentle tap with a hammer or was that snippet of info from one of the suppliers in Oz.
In any case, make sure you are trying to turn the lock ring in the correct direction.
If you have the BM upside down and are standing with the pump motor toward you, in other words if the head and lock ring are furthest away, then the ring must be persuaded to turn anti clockwise or to the left hand side from the top of the lock ring.
It is recommended to re tighten it by hand and from then on it is easy to undo for pump removal.

PS don't lose the o'ring between the pump motor and the head or body of the pump itself.

Yep that does the trick (also with stuck cylinder heads ;- )
There are also small mallets that have hard plastic heads that can also do the trick.
And then after cleaning just do not tighten it too tight.....

But check for leakage before starting to brew ;-)

I would have thought that considering Speidel recommend removing the pump for cleaning after every brew session, that they may have supplied the correct tool with the unit from new, or at the very least, offer one as an accessory.

Would it be advisable to put some (food safe) lubricant on the threads?

Wouldn't do any harm. It's good food for the O-rings also. Also means that it doesn't need to be tightened very much (Spiedel recommend a low level of tightening anyway).
To brew or not to brew, that would be a stupid question !

In that case, if you have an old bicycle chain, you can easily manufacture such a tool ;-)
Just wrap a chain around the pump...

if your grip slips then you could try fixing the chain with a bit of wire...
