[Healeys] Water Pump Pulley Circumference

[simon.lachlan at homecall.co.uk (Simon Lachlan)]

I?ve got 2 rebuilt ones here. One of each type, both narrow. Both off 6
cylinder cars.

Early type            11&3/8?

Later type           10&3/4?

Not easy to measure though I did each a couple of times.

Comments? Good luck with a County pump!

Greetings

 

Today the new six-cylinder water pump for the BN3 arrived from AH Spares.

 

I have noticed that the ?within-the-groove? circumference of the new pump is
11 ? inches, while the ?within-the-groove? circumference of the old
(original) pump is 14 inches.

 

Apart from the pump running a little faster I can?t see that it will make
for any other differences.

 

Does anyone have a pump they can conveniently measure please? Plus any
comments would be appreciated.

 

Many thanks
