Thread: Information about seal in water pump

Here are some images etc of the said pump and it's internals, this is a rough sketch of the spindle etc

here is an image of the impellor and spindle and the seals, the worn out seal is at the bottom, the 2 upper seals are Series 1 but neither will fit

the pump must be a re-manufactured pump, possibly using Series 2 bits??

hoping that this might jog somebody's memory, cheers Dennis

Hi Dinty,

I see youre not having much luck with your waterpump repairs. The following link is what I have done to repair klonks waterpump, Its a bit of work and will cost if you have to get someone to do it for you, but a couple of hrs would do it and next time only the bearing would have to be machined.

The bearing and seal cost about $45. Its a 5/8 mechanical seal and a 5/8 waterpump bearing, any good bearing shop would have them


A well used 80''called Klonk

Just looked at a Bearmach water pump repair kit I have 'in stock' for Series 2/3 and the shaft/bearings are different dimensions.

Seal is coming up at 1.430" OD

Didn't I read somewhere that a tractor (maybe Grey Fergie) pump innards were about the same ?
