Is this right?

Hi all,
Apologies from the outset - I am no expert on gearboxes and
clutches etc. As far as I am concerned rotational force from the
engine goes into them, witchcraft happens and the props turn...
Anyway. I had a recon (weird/hodge podge) S2a gearbox fitted. It
leaked like a seive and then gradually got worse and worse until
I could no longer select any gear.
One of ours, Violet, has come up trumps and supplied a Series 3
gearbox, complete with the hydraulics and a clutch. I do know
that the clutch is different between the two, but one small
thing is bothering me, however bear with me as I don't know what
the correct names are. I shall try my best to explain.
On the old S2 clutch housing/cover there is a kind of funny
shaped steel thing at the very centre - its held in place by the
'fingers' but is otherwise able to spin freely. It is obviously
the point at which the clutch release mechanism inside the
bellhousing interacts with the clutch cover.
On the S3 clutch cover, it isn't there - it's just the 'fingers'
and then the hole where the shaft goes through. Is this correct,
or is there something missing? I have looked at the various
images in my workshop manuals (I have about four or five
different versions for each model) and they are all a bit vague
in this area, however I know folk around here will know.
Thanks in advance.

Sounds to me like you might be describing the clutch release
bearing FRC 4679.
Don't buy a blue box one unless you are happy to take the
gearbox out and replace the bearing again in a couple of months.

The S3 version clutch is a cheap nasty affair, there is nothing
missing from the cover, the fingers are operated directly by a
crappy plastic release bearing, in turn worked by a crude
pressed steel fork thing ::)..personally I would do the old
bellhousing swap thing to keep the properly engineered 2a
release set up...

As he said, nothing missing its how the S3 clutch is
The S3 release bearing (a separate part unlike the S2 where its
part of the gearbox) pushes onto the finders - don't fit a cheap
one, you will regret it
I wouldn't agree with swapping to the S2 bell housing. The S3
system works fine, for many LR's for years and is a pretty
standard system used all over the automotive world since the
70's and in many cases still is
The S2 system while long lived is massively over engineered (the
S3 system will easily last the life of the clutch plate anyway)

^ ..I like massively over engineered, that's why I like Land
Rovers..... and why I'm less keen on many elements of the S3
with it's introduction of cheapened plastic parts etc.. a sign
of it's times of course..

I,ve changed the bellhousings over from series 3 back to 2a .Its
not a difficult job.If your not sure I can give you a hand if
you want.

Actually I quite like 'over engineered' too. I had series
three's for years (this is actually my first ever series 2a) and
I never had a problem with release bearings or clutch
mechanisms, but having received the replacement release bearing
from Craddocks yesterday, I am kind of glad I didn't manage to
fit the damn thing.
Despite telling me it wouldn't be shitpart, what turned up was
indeed a shitpart bearing. The plastic sleeve thing is extremely
cheap and nasty and the bit of the bearing that interfaces with
the clutch cover is nowhere near the same sort of shape and size
of the original.
So - plan is I am going to try to free off the old bearing. I'll
soak it in some petrol or GT85 for a few nights, see how it
goes. I sprayed a bit of GT85 on it and it does move ever so
slightly now so a good soak might just do the trick. If that
fails, John I will then love to take you up on the kind offer. I
have just butchered carefully cut out the strengthening bit of
the crossmember on one side to enable the fitting of the series
3 slave cylinder though which was a right pain in the arse so
I'd prefer to stick with the S3 clutch if I can. Whatever
happens I aint fitting that piece of shite Craddocks have sent
me. I have no desire to tear it all back out again after a few
months. :2mo5pow:

I hear what you're saying about having made space for the S3
slave.... however I'd never use a crappy S3 type mechanism if I
could fit a proper 2a job, ( it's way easier to bleed too )
Trust me, take advantage of the kind offer of assist from
Johnpirate !

Well, I was tempted to change the bellhousings over but after a
soak in petrol, and liberal amounts of GT85 (love that stuff)
the original release bearing freed off. It was basically chock
full of mud. I kept spraying GT85 in until it came back out
clear and felt right. I know that it will probably not last
terribly long, but I reckon it will still last a lot longer than
the shitpart one.
After re-adjusting the brakes which were probably a death
waiting to happen (think nothing one minute, total lock up the
next, randomly) and topping up the gearbox oils (for now, intend
to do a full oil change later) I went for a quick blat and I can
say it's a million times better.
If you recall I could only manage between 15 and 20 MPH on the
M62 up the hills and it would not accelerate, it always felt
like there was something dragging rather than a lack of power.
Well, now it will accelerate decently and I managed 50 MPH from
junction 20 to Junction 19 on the M62 earlier. I didn't have
time to go further but early indications are it's cured.
The new gearbox is, comparatively, silky smooth apart from
dropping from third to second where it grinds a bit, although
this is absent mostly if I double declutch. I can live with it
for now. The clutch is a lot better than before, I can even hold
it on the bite (impossible before) and speaking of, the bite
point is a lot more predictable. The master cylinder is on the
very end of the adjustment though, don't know if that is right.
Just the terrifyingly lethal steering to sort out now, and it
ought to be a thoroughly nice Land Rover. After that I'll be
onto 'enhancements' (like paint that doesn't look like it was
just thrown on, and door seals that...seal)

At least you've got a viable, usable motor now, that's the main
thing ! ...You can always tinker and change bits later if and
when you can be arsed ! :toothless:
