    Default Water pump

    I have been trying to fix a leaky water pump in my old Chevy truck..... tried lots of kits with limited success.

    I decided to try a new approach . I bought a NOS good quality bearing ( the bearings available now are Asian crap )

    The grease had dried up in the NOS bearing, I drilled a hole into it and pumped in high temp . grease , filled it right up .

    The old carbon seals are OK if you use the vehicle a lot, but leave them for a few months and they weep .

    I opted for a modern mechanical seal . Bored out the pump housing . Its been in use 6 months now, been performing great .

    Thanks for this, amazing what can be repaired with a bit of lateral thinking.

    Great result. Can't see in the pic ... Is the mechanical seal ceramic or some hard wearing sintered metal ?

    Nice work. I have done a similar thing on my Toyota DA115 crane truck. Water pump leaking, so retrofitted a common mechanical seal into it.
    Gold, the colour of choice for the discerning person.
