A200 Hydraulic pump leak, and servo issues

[Peter Golledge]

Geraint,

It is worth doing the full R&R in one hit.  With 3 x Type 44 under my care I
have never seen one of these pumps fail in any way other than leaking.  The
rebuild is pretty easy.  I did find that the "body" seal (only very big
O-ring) in my rebuild kit was too small (thickness) and I had to source one
from NAPA for ~ $1.

Regards

Hi,
the car is a 10v 200tqa

I have a dribble from one of the caps (that require the modified 'drag link
tool' to remove)  on the front part of my hydralic pump.

I have a  rebuild kit that came with the car. should that tell me something?

my questions are:
1. is it worth replacing the o rings under only one of the caps, or does a
leak there suggest that the whole pump needs an overhaul so doing one is a
waste of time?
2. do the mechanical parts of the pump fail or is it generally just the
seals?

I have seen stuff in the knowledge-base about how to rebuild pumps, but not
why- hence the questions.
