Ol pumps

[TonyC]

Hi All,

Moving on from starter motors and ring gear, can we turn our attention to oil pumps.

 

Does anyone know who the manufacturers are of current replacement oil pumps from usual sources.

 

I removed the pump in my 6, at 7000 miles, after a nut and bolt rebuild by previous owner. Clearances - rotor to spindle, and rotor to bore were above tolerance although end float was ok. The replacement pump wasn't very much better (yes clearances were out of tolerance) but I fitted it anyway.

 

Since doing that I have scoured tinternet and forum and get the feeling that, well, all new pumps may have the dreaded scourge of 'not made in Britain' and getting a pump within tolerance may be a 'bridge too far'.

So questions are:-

- Is there more than one manufacturer of pump and if so who is the best, and how can they be identified?

- are they all made in Asia?

- has anyone found the same problem and maybe had the spindle and/or rotor electro-plated to reduce operating clearances.

 

I have done the 'blue printing' exercise so end float is less of a problem as it can be corrected if it is excessive, but it is these clearances between moving parts that I would like to have within spec.

 

Many thanks for your valuable input.
