[Healeys] Strange Timing Setting

[Oudesluys]

It should pump/click every 15s or more. There is always a slight seepage 
through the plastic valves. They are never 100% leak free. If you hear 
it pumping more often the chance is that the seat faces of the valves 
are dirty or corroded. This can usually be remedied by carefully 
removing the valve assemblies, prying out the plastic valves very 
prudently, clean them and clean the faces of the bodies. If very 
corroded the valve assemblies can be renewed. When fitting them back in 
the pump body use new rubber seals (flat rubber rings). If they are not 
available you can usually get away with fitting suitable O-rings.
If the pump is out clean the contact points with a strip of 2000 flower 
paper.
When the points are severely worn, dismantle and rebuild the pump and 
keep the 3-layer membrane if possible as the new single layer membranes 
are of a lesser quality. Be very careful not to damage the thin kevlar 
layer when removing the pump body, separate the layers and rub some 
talcum powder between the layers very sparingly to create a supple 
membrane assembly.
If you follow the SU instruction to the letter the job of rebuilding is 
a piece of cake and should not take more than half an hour. Parts are 
available at the SU dealers. (Google)
