[xk] Steering gearbox question

If we could get back to the subject of Jaguars for a moment, I would like
some advice. (Risking that knowing this list, I will probably get more advice
than I need.) Here is the question: Now that I have my steering column free
of the car, how do I know if the gearbox needs a restoration? Taking it all
apart looks like quite an adventure according to the Service Manual and JEC’s
book “On Jaguar XK120 Restoration.” Balls fall out (that must hurt!), lever
arms are difficult to remove, careful of this, careful of that, tighten just
right,…etc.

Is there some simple test that I can do to check if it needs work – while
the column is free of its system? And forget about asking what it was like
before I took it apart because I have never driven the car. The real answer
is probably that I should take it apart while I can easily get at it and
after all, it is 50 years old. Thanks in advance for your advice!

Carl;
You really should have checked the “steering slop” (freeplay) with
the box still mounted to the chassis…
About the only thing you can do now is to turn the steering shaft
(via the steering wheel) limit to limit… “feel” for any binding, roughness,
“excessive” play etc…
Even if all “feels” good, any extra play will manifest itself “after”
you re-install it in the car…
Try clamping the pitman arm in a vice, with steering wheel in place,
“turn” the steering wheel to “feel” if there is any freeplay… in other
words, if a spoke of the steering wheel is at 12 O’Clock and can move to the
1 O’Clock position, you have problems! The steering should have almost no
freeplay at all when checked like this… I don’t know if there is an
“allowable spec” on this or not… maybe another lister can help here.
At a minimum I would replace the seals, gaskets and grease… Once
you open the box, if your worm and balls are rusted, they need to be
replaced. (no comments from the Peanut Gallery!)

Carl-just dismantle it according to the service manual-just don’t drop the balls,
it do hurt -grin-take photos on the way -look for wear, install new wires. Just
check for play in the arm that comes out of the box-if you get into trouble on
reassembly, you always have the list. Cheers, Rex

Hi Carl Hanson, Rex La Brie & all – Carl, I recommend doing this if only
because of the steering unit’s age, now 50 years on (and the resulting
potential for unsafe operation). The Mark VII and XK120 Service Manual,
pp/I.15 - I.19, walks you through it – pp/I.10 - I.11, Plate I.5, gives a
visual reference that’ll prove invaluable. If you’re lucky, this will work
OK – if any problems, come back to the list with specifics – some of us
can probably help, eh! Take care – Larry Martz*****
Carl-just dismantle it according to the service manual-just don’t drop the
balls,
