I've got the water pump apart and the splines at the top of the shaft (and inside the impellor) are worn. I'm going to have to get the sealing surface on the underside of the impellor machined so I thought I might ask the machine shop to cut matching key ways on the impellor and shaft and then fit a key that would br held in by the top (LH thread) bolt. Has anyone done this before?
The top cover of the pump has erosion/corrosion on the angled face that sits just above the impellor, has anyone had this filled by welding and then machined?
Thanks,
John.
