King Pin or Swivel Pin

At Reggies MOT, whilst my welding was OK, I have an advisory on the
Front Nearside "King Pin or bush".

As I said in an earlier post I am a weekend mechanic!

Now my Rover P4 110 has "King Pins" however with the Land Rover having a
swivel hub, do I assume that the tester is referring to the upper and
lower swivel pins?

Cheers

Peter

Yes - while not actually a king pin on Landrovers, the upper and lower
swivel bearings have the same function as a king pin.

Thanks, now for the supplementary question!

Is it best to replace pin and bearing AND upper and lower at the same
time?

It *might* be as simple as just removing a shim or two to solve the problem.

The MOT computer menu has not got a code for a Landrover swivel hub, so the testers put down the nearest they can find, worth checking with the tester exactly what needs doing.

What is Reggie?

You'll most likely not need pins. If it is beyond the remove 'shims
stage' do top and bottom at the same time.

Sorry, "Reggie the Veggie" is a 1990 2.5TD 110 CSW (running on
vegetable oil)

If there's enough play to warrant an 'advisory' then the bottom bearing will
be worn. Don't mess about removing shims, get them sorted, it's not a hard
job. If you come unstuck, you will get all the help you need on here!

If I remember right, yours has a Railko bush on the top and
a taper-roller on the bottom. If the play is at the top, then
it could be the upper pin - the Railko swivel pin is inclined
to wear a bit (it usually goes a tad oval), but often before
this the thrust washer (a disc of some interesting material)
that sits under it in the bush is likely to, er, dissapear (as
in get turned into an oily mush). Taking out a shim will
compensate, probably for quite a while, but really the pin
needs to come out, be inspected, and a new thrust washer put in.
You can actually do that with the hub in place, but it is heavy!
The upper pin housing is surprising robust, but does need to
be checked - you can see in it with the upper pin removed.

If the play is at the bottom, then the roller bearing could be,
in trouble - but beware, the lower swivel pin relies on the upper
being tight - any major slack in the upper pin can make the lower
one look knackerd, though usually you'd get oil leaking through
the swivel ball oil seal as well. Inspecting the lower
bearing without stripping the whole assembly is not easy,
but usually only fail when the swivel is being lubricated with
water/mud rather than nice clean oil.
