It’s my thought that the rubber must still have some give? softness
for this style of pump to work correctly! All of mine are as hard
As hockey pucks.
Hmm…I guess I hadn’t thought of that Bob. I wouldn’t think the softness of the rubber would matter as much as with the rotax type impellers with vanes which need to bend and stay flexible.
When I get it all back together, I’ll see how these pump water. Even the kd4 I took apart last week has an oscillator type impeller. The water pump housing is a 7 slit type but would not accommodate a vane type impeller. Maybe it’s a pretty early kd4. I will look at the serial number and see what it says.
EDIT: the kd4 is #123829 so it’s a kd4-1 and part of the first big batch of kd4s they made in 1946. Probably used up kb housings before they moved onto the 3 slit type and rotax impellers.
