Hi,
David has already steered me in the right direction with regard to the =
reamer.
=20
And a further query=E2=80=A6..
It seems very likely from what I confront in my car and from the advice =
received to date =E2=80=93 for which many thanks -..it seems very likely =
that the issue is caused by the pump plunger being stuck or, I suspect, =
not quite orientated.
Despite what you guys suspect by now(!), I study form religiously before =
I delve into these things and have been brought up short by a section in =
the BMC manual, Section G8, =E2=80=9CPump Valve=E2=80=9D. One is told =
how to put the =E2=80=9Cpump body=E2=80=9D back in using one of many =
mythical special tools and then the manual addresses the insertion of =
the =E2=80=9Cplunger=E2=80=9D (piston):- =E2=80=9CThe pump plunger is =
prevented from rotation when in position by a guide peg carried in the =
front casing. When assembling the pump, the plunger should be inserted =
with the flat on its head facing the rear of the unit. It is possible to =
guide it past the guide peg by means of a screwdriver inserted through =
the side of the casting=E2=80=9D.
1. Can that procedure be carried out when the OD is still in the car as =
is implied by the manual?
2. If so, where is the access point through which one can insert a =
screwdriver? (Strikes me that oil would gush out=E2=80=A6..If the pump =
ever restarted pumping!)
3. If not so, is there a trick involved in getting the plunger up and =
correctly sited?

Smacking the check ball will not make a new seat in the pump. You must =
cut a new seat with a special reamer.=20
