[Saloon-lovers] Leak In 420 Power Steering Box

I have a 1967 Jaguar 420 which has a leak in the power steering box. The
fluid appears to be coming out where the shaft exits the box going down to
the steering arm (pitman arm?). Does anyone have any experience in
repairing / rebuilding one of these boxes?

The box still functions fine, so if just replacing one seal could do it,
that would be great. Does it take special tools? Know any good
rebuilders? Can an amatuer do it? (I have a large hammer and a cutting
torch…)

So far the leak requires refilling the pump reservoir once a week, but the
“week” seems to be getting shorter and shorter… I am temporarily
between ‘normal’ cars, so I am having to (i.e. getting to) drive the Jag
every day to work, but am worried about being reported by my employer as a
portable environmental hazard.

Thanks for any help…

Let me reply to my own message:

I did some digging through the archieves - found 69 messages dealing with
power steering leaks and almost all were negative. Sigh…

The one ray of hope was that one person tried a chemical leak stopper and it
worked to a point… worth a try I guess. Has anyone else had any luck with
such chemicals?

I was thinking of installing a drip pan under the steering box with a small
sump pump, and just pump it back to the power steering pump…

try a sealer for an automatic transmission. These make the seals expand
slightly and it might help. john shuck…beijing
