Clutch primary oil seal
Can anyone tell me if it is possible to remove the primary oil seal without removing the housing that it fits into from the engine?
Step by step instructions would be nice. Clutch is already removed.

yes, just dig it out, but when re fitting a new seal, put tape around the primary gear to protect the seal when refitting the replacement.

I read in the Haynes manual that you can pull on the primary gear to remove the seal.
Digging the seal out sounds a little crude and I don't want to damage it's housing. Can anyone confirm the Haynes method? I didn't think the primary gear would fit through the oil seal aperture?

Digging it out wont harm anything as long is you dont grizzlyit. and to fit the seal cut a plastic coke bottle than a slit on the side so the plastic can eclose and open rub a bit of oil on it and ream the seal in with a rubber hammer.

Thanks for the advice.
Job is done now. I have the tool for fitting the seal so getting the new one in was easy.

Leaking oil clutch seal in a pre A-series 1380cc - help!
Hello
Just ran my newly built 1380cc (pre A-series) on the rolling road and notice oil dripping from the clutch cover drain hole. l fiited the engine with the uprated MS oil seal and the engine also has two large breathers from the rocker cover and the transfer gear housing.
l must admit that l did over fill it with oil and will be running it again this weekend to check if reducing the oil will cure it.
Has anyone else had the same problem? If so can it be cured without replacing the oil seal?
Thanks in advance.
J.

Clutch primary seal?
Does your clutch slip at all? If oil is coming out where you say it is (and to be honest it doesnt sound like much) then it may be the primary oil seal that goes round the end of the driveshaft. Its not a hugely difficult thing to replace, just very long winded because you have to remove the clutch assembly. Personally, Id only worry about this if the clutch starts to slip a lot because it is such a pain the replace. My engine looses about 2 lt a month just standing in the garage from the gear lever seal. I dont use the car much, so I dont worry.

oil leak
i recently purchased a 82 mini 1000 imported to germany from the UK, the guy i bought it from was selling it for a friend still in the uk and very little information came with the car so i have been trying to figure out what parts are compatable with my engine/trans. i have located an oil leak that i belieave is coming out of the clutch oil seal and since i am goign to pull it apart i wanted to get the clutch to go with it. my engine number is 12hd17 which i believe is a 89 mg metro engine, so what clutch and oil seal do i need cause its kinda hard to figure out. i have to ship this car to america in a few months so i have to sort out all the engine leaks before then. are austin 1275 parts compatable with this engine?

Upgrade clutch
I have a 1275 engine with a verto clutch and an inertia starter (unfortunatly the engine number is missing). It has an oil leak from the crank seal which is causing the clutch to slip. The engine has been lightly tuned so I would like to upgrade the clutch while repairing the oil leak. what is the best option?

re
Could also be oil leaking onto the clutch. Perhaps the seal has shrunk during the period of being laid up and could do with replacing. There's a little jiggle pin on the bottom of the clutch housing which looks like a split pin. If there's oil dripping from this then it's a sign it could be leaking because that part should be dry.

drip of oil
I would guess it's the oil seal just starting to go - it may only be coincidence that it's happened when you changed oil, certainly that Classic 20/50 ought to be OK.
It does mean that eventually oil may get onto the clutch and it will start to slip. I don't know how long that will take, but when it does you will have to change the clutch and the oil seal. It can be done with the engine in situ, though it can be quite difficult if the flywheel decides it doesn't want to come off!

clutch
Hi, its probably a leaking slave cylinder that is causing youre clutch to drag. to check this have a look at the gap between the clucth cover and the big nut on the end, there should be about a 6mm gap that closes to about a 1mm gap when the clutch pedal is depresed. altenitivly there could be oil on the clutch plate causing it to stick on ( new clutch and seal needed ) or if its been laid up for a while the clutch may be stuck, to fix this put the car in second gear with your feet on the clutch and brake pedals and briefly crank the starter, good luck, Abs.

Oil leak - please help!
No, my clutch doesnt slip at all. Just a lot of oil all under the engine. You say 2l/month from the gear lever? Isnit a little bit too much? In Haynes manual (sec. 7A, pages 6 and 7) there is explained a way to fit a nylon bush O-ring just before the selector shaft oil seal. Perhaps that can help...

Clutch slip
Hi everyone.
I am replacing my clutch (pre verto) because of slippage. I originally thought the problem might have been the primary oil seal but it doesn't appear to be leaking oil. I thought this because I didn't think it was so long since I last changed the clutch but my memory is a little foggy! (too many minis!!)
My question is what is the thickness of a worn clutch plate? Because mine isn't worn to the rivets but there is some (very little) oil in the clutch housing but nothing on flywheel or pressure plate. And as I said the oil seal seems fine. I just don't want to spend money on a clutch plate and put everything together to find out it still slips.
Any thoughts?

Clutch Seal Protector
I think you may be thinking of the oil thrower ring, made out of a nylon type material? it has an internal spline that allows it to slide over the primary gear splines and but up against the primary gear oil seal? If so this is there so that if the primary gear oil seal in the clutch housing fails it will 'throw' the leaking oil off the crank/Primary Gear as opposed to letting it run along the primary gear and onto the clutch plate thereby avoiding the obvious problems friction material and oil combined would cause.
I have had some engines with & some without this thrower. If you have it or can get hold of one I would recommend that you fit it. However it is not designed for a big oil leak just a small amount of seepage that you would see coming out of the 'witness hole' in the bottom of the clutch housing. If oil is dribbling out of this hole no number of throwers will save your clutch plate!!!
Hope This Helps

oh my god!! whats gone wrong????
For it to suddenly go like that I would imagine the oil seal into the clutch bell housing has let go and dumped oil onto the clutch plate. You might be able to see in there through the inspection hole or if you take off the breather. You might find oil dripping out of the bottom of the bell housing too.

Oil leak
Its only a guess, but Id say your clutch oil seal has gone ;-) You can check it without removing the engine by undoing the front lower engine support and the clutch side engine mount (low down in the rh front wheel arch) and then jack up the engine so you can unbolt and remove the clutch housing. It is all a lot easier if you can get the engine out though. It is highly likely this is the cause of the problem given where the oil is coming out.

clutch chatter, PLEASE HELP
After a clutch renewal, In downshifting at low rpms, clutch chatters producing big noise and vibrations. I renewed the non-verto clutch of my 1974 Mini 1000 recently: Ive changed the disc, the spring, the bearing (with new ones from Minispares) and remachined pressure plate and flyweel planes. The oil seal is in good conditions without any leak. Please help!
Posted: Dec 26, 2005 11:13 AM
I assume you have checked and adjusted the clutch push rod and the throw-out stop as per the manual? Mine needs doing quite regularly.
I would change the oil seal and clutch plate regardless (presumably you've already got it stripped down).
