Fixing up a spare motor and gearbox - when the engine is running, I find oil pouring out of the hole under the clutch, you know the one with that big split pin through it.

I think I put in the crankshaft primary gear oil seal a bit crooked.........

Anyway, I've got to pull it apart to fix it but there is another question - should there be a thin washer (alluminium I think) on the end of the crankshaft, before I put on the flywheel housing with a new oil seal on - then the clutch and clutch cover??

Thanks

vcheck to see if the spring is still in the seal.
it should have a thrust washer (brass) with a tapered edge that goes at the back to the crank, then the primary gear thru the bell housing the the locator (round ring with half machined away) then the C clip to hold it all in place.after you check the end flaot (4thou) the backing plate goes on, the the friction plate (clutch plate) then the flywheel, then the diagphram all bolted up with the locator and locking plate on the end of the crankshaft and then the big bolt in the end of the crank.
If i have missed anything im sorry but it shoud all be there. oh yeah the gasket inbetween the bell housing and the gearbox/block.
no aluminium spacer or anything in there as it will chew it up and spit it out.
unless its an aussie thing.

Thanks for the reply so quick. I know that all of the parts were put back when I re-assembled things - it's just that damn oil seal that is causing me the grief, or at least I think that's all the problem is.

I used a brand new oil seal so I assume the "spring" was there but I'll let you know how I go.

they have a tendancy to fall out if you knock the seals in. pull the spring off the back and give it a few more turns to make it tighter to start with. but you might have also damaged the sealing lip if you dont do it properly.
wrap tape around the teeth on the primary gear to stop damaging the seal lip if you dont have the correct tool.
you can cahnge the seals without having to rip the bell housing cover off also.
you must find someone with the correct toop to do it and it takes 5 mins to do it all.

Umm...sorry about the silly question (I'm going to tackle this today).

Assume that I leave on the Bell housing, but remove the primary gear to replace the oil seal....(is that in fact possible??)......if i were to take the spring out of the seal, then put the seal into the hole where it's supposed to go, how do you get the spring back in to the lip on the seal????? Clever manipulation of your little fingers???? AND how do you know that it's all the way in the groove where it's supposed to go??

Cheers

you have to put it all together first them put it in.
You must have the right tool or you will be wasting your time, most garages will have them and maybe a local garage might even lend you one or rent you one.

Any mini garages have them so they are around.

basically you pull the primary gear out and the seal comes out with it. you then install a NEW seal and put it all back in the same way it came out, the special tool pulls the gear out and another toll allows you to put the seal on with out damaging the lip and the 3rd tool allows you to put the the gear and seal in in one motion and seats the seals to the correct depth with out knocking the spring out of the back.

You will be damned lucky to find any garages (apart from Mini shops) with those tools, this side of the ditch..
Not hard to make though, pics are in the factory manuals- both BMC and Leyland Oz.

by the sounds of it this person doesnt have the tooling or capapbility to make such tools.
maybe easy for you who has been doing it for so long.
yeah maybe you can make him a set doc nice of you to offer.

I know they are not that easy to come by as i sen ta set to GR just before xmas and he loves them and wonders how he ever worked without them.

Ok fellow mini freaks (and I mean that in a nice way) - here's how I fixed the problem.

Sure enough, when I pulled things apart, I had damaged the seal last saturday when I put it in - hence the leak.

Bellarine Mini Centre has a small length of metal tube that slips over the primary gear so that you dont damage the new seal when you put it on. Using another length of tube that is slightly bigger than the one over the primary gear, you place your new seal in the hole, then by using an old seal ( that sits perfectly on this second tube) you gently persuade the new seal all the way home. There's very little room so you can't swing a FBH!! The BIG mistake I made with the first seal was that I was in a hurry as I was running late for a wedding - I saw that it was crooked but my state of mind said "stuff it, she'll be right".

Lesson learned - do it right or do it again.

Thanks again for your input Minicranks and Kev.

Hooroo

glad to hear your back on the road. i hope you cleaned up the clutch plate with some brake clean or the likes to stop it slipping a bit later on.
congrats on getting it fixed.

Yep....do it once and do it right heh......

Replaced the clutch plate as it was oiled up (just a bit). All is well now.

Did my explanation make sense to you???

Is there a special tool that you can buy for putting in oil seals??? It seems to be a bit of an art if the one being replaced is still in the car?? Dead easy if you do it on the bench though.

Thanks again
