Advice please - oil in my one shot grease swivels
Guy Lux
Ive just noticed two stickers above the radiator of my Defender 300tdi
which tell me that one shot swivel grease had been applied to each
swivel housing. This after a few months of faithfully topping up with
oil, (just like the Haynes manual tells me to), while the oil was
faithfully leaking out.
I know about one shot grease, as there is a fair amount of chat here
about it, apparently, if your swivels are shiny, they are oil swivels,
and if grey, grease swivels, (I have grey on one side and shiny silver
on the other so had no idea what was going on).
I have two questions that I would be grateful for any suggestion on.
1) Can I simply re-apply one shot grease as -shot two- or should I
take the whole lot apart and start again?
2) When I take the plastic caps off the front wheels, one is oily
underneath (grey swivel side as it happens) and the other dusty rust,
which one (if any) is correct/least bad and what is likely to need
fixing?
Thanks in advance, and sorry if I dont reply straight away, I go
through Google, and havent quite worked out this news group stuff yet.

Well, hopefully they weren't just decoration ;)

New one on me, that is! My understanding was that the grey ones were
just later ones. Sounds like the grey one is a replacement. The one-shot
is ok for any LR.

I suppose you could just drain it - it's thixothropic apparantly, so
take the thing for a run, the grease goes liquid and you drain in the
norkal manner. Refill with fresh one-shot. Warm the sachet first and
also make sure the steering is full left/right lock to allow the stuff
to get past the internal bit of the ball - if you don't, it'll still go
in but with difficulty.

Hmmm - in the ideal world there is an internal seal which is supposed to
keep axle oil in the axles but if it leaks then the hub caps get some
oil there. Nothing to worry about unless it's excessive leakage. The dry
side sounds as though the seal is working. I assume the bearings have
grease (ordinary) ?

Google is fine, but you have to be on-line. If you're using OE then
setting up newsgroups access is easy, there's a "wizard". You will need
to know the name of the news-server your isp uses - if you are with BT
it's called news.btinternet.com. MSN call it msn.news.com. Ask your isp
if necessary.
Incidentally, if you do a Google Advanced Group Search for your topic of
interest, there is much detailed stuff there from this ng, have fun!!!

news.cis.dfn.de - I use it as a backup to the ntl server for when it
crashes. You have to register but once you've done that you use it just
like any other news server. http://news.cis.dfn.de/ reveals all. On the
oil under the hub dust seals I have traces of oil under my left one, and it
leaked out from the right one when it got pierced - I admit I just put a new
dust cap on and it's been fine ever since. Must get round to putting in the
one shot I got.

The colour of the swivels makes no difference. However if grease is leaking
the you have a problem either with the lower bearing or top pin in the
swivel housing, these allow excess play and a gap for the seal part # FTC
3401, to leak oil or grease.
All Land Rovers will take one shot grease part # STC 3435
As they come as a "one shot" these are measured amounts. You need to drain
and refill for the correct amount to be applied.

Its good to know all is not lost and I especially appreciate the part
naming and numbering, I will drain then check the relevant areas
before refilling.
If you are interested, it was a chap called -Bob- who wrote about the
different colour swivel pin housings.
This was what he wrote back in 1999:

If your swivel pin housing are chrome plated, then they are usual
filled
with oil.
Check for drain plug below filler plug.
If housing is discoloured grey/black then they are nitride hardened
and are
filled with one shot grease....no drain plug.
This was introduced to overcome oil leaks and to stop seal from
premature
wear.

I understood that "one shot" should not be used on series vehicles as they
rely on the splash lubrication of oil for the top bearings of the swivel.
Can someone please give an answer to this?

Why? One shot will lube the top bushes on a 110 so why is a Series any
different?

I thought the difference was related to "series" LRs having plain
railko bushes for the upper swivels, while 90/110s have roller-bearings
for both upper and lower bearing.

Not all of them. My '89 has railko's at the top. I know because I
rebuilt the swivs a few years ago. Later ones have roller I believe.
One-shot is not a "solid" grease - it liquifies when stirred and behaves
like a liquid. So it lubes by splash. Proof of this? I had ocassion to
have to remove the top pin not so long ago - lots of lube in there so it
obviously works.
People who use an ordinary grease in their swivel will not get the
splash effect and accordingly will not have lube getting to the railko.

So how does the one-shot manage to reliably lubricate the half shaft
universal joint?
Phil
Mike Buckley
then it'll get lubed by one-shot!

Because with oil there is a pint of fluid in the swivel, this means that the
universal joint is permanently sitting in the lubricant. I'm not sure of
the quantity of grease used but I didn't think it was anywhere near that
quantity. With the permanent four wheel drive vehicles constant velocity
joints are fitted, which I believe have there own rubber gaiter containing
CV grease, which is why one shot grease can be used for the lubrication of
the swivel bearings.

.35 ltrs / .60 pint. (LR Workshop Manual - Part 1 / Section 09 - p3 )
Which is what's in each sachet.
All 90 / 110 vehicles are perm 4x4 (excepting a few very early models)
and I can assure you that there is a cv joint and it most certainly
isn't contained in it's own gaiter within the swivel.
Series have UJ's iirc but the swivel/hub assembly is essentially
identical.
On both Series and coilers, some users choose to fit an external leather
or rubber gaiter to protect the exposed surface of the swivel. That's
got nothing to do with protecting the CV. That runs inside the swivel,
in oil or grease.

Mike, I think we may be talking at cross purposes here. I was talking about
Series vehicles and have rechecked my Series 3 LR Workshop Manual (Page
09-1) and it does state 1 imperial pint, hence my concern over using a
sachet of grease.
I have also checked up and found why I thought there was a rubber gaiter on
the CV on the perm 4x4 vehicles. The last one I saw in bits was a Discovery
2 which doesn't have the chrome balls and has a CV with a rubber gaiter and
the top and bottom pins are sealed for life units. I made the assumption
without thinking fully that all perm 4x4 must have CVs with rubber gaiters.
Agree on the leather/rubber gaiter point, have got leather ones on one of
mine.

situation regarding one shot as I understand it:
Land Rover one shot grease was produced for lubrication of swivels
containing two swivel bearings. According to LR, the grease was too
thick to effectively lubricate the top bush of a swivel - the lubricant
has to be drawn by capillary action onto the bearing surfaces which it
doesn't do effectively - hence the 'not recommended' tag unless it's
used in a twin swivel bearing situation.
There is another type of 'one shot' - marketed by at least two other
companies. This is similar to LR stuff but is slightly thinner. This,
they say, allows it to be used in all types of swivel housing. If you
really want grease in a series type motor, I'd use that.
To compound the argument further, there was at one time a vicious rumour
going about that LR had changed their minds and they'd decided one shot
*was* ok for older swivels ... I have yet to see evidence of that
statement though and, until I do, any doubt in the mind is worth oil on
the bush!

Your privilage. I bought one-shot from a LR main dealer who was asked
whetehr it was ok for a railko fitted 110. And in 40k miles I've had no
problems and no excessive wear. Understanding the properties of the
grease makes me quite confident that it's working just fine.
Mike.
