new BIS clutch

[markymarc]

Hi guys,

Have been having a few problems with a slipping clutch and did adjust which worked for a while but am now thinking of changing.  Just really wanted to know (again from my VW days) are there any seals (gearbox or engine) that are worth looking at or replacing at the same time?!

Many thanks

Hi Marc,
You have got your rear crankshaft seal which of course is on the opposite side of the flywheel to the clutch so if it leaks the oil cannot get on the clutch plate easily. If you have a worn gearbox or it has been overfilled then you can get oil on the clutch in fact I have this on my 500 at the moment. The almost new clutch slips under load or on steep hills and you get an effect a bit like semi-automatic transmission with an anti-stall device. I will have to sort it out but as my 500 is the only running or road legal car I have at the moment I am living with it as it is my daily driver. If you think that you have an oil leak a visual inspection with the little flywheel cover removed may help to spot a problem. If it is all messy in there you can fix a piece of clean card or paper inside that cover then give the engine a little run to see if you get any oil specs thrown out and with a careful measure you can tell which side of the flywheel it is coming from

Hey mate , if I knew all the answers then I would not be relying on a 39 year old Fiat 500 that has done over 100,000 miles as my daily driver , forgot about the MOT on the modern hack (going in on Tuesday) and have a 126 with a screwed gearbox and a new engine that needs a total rebuild after only 400 miles    MOTs due on both the Fiats also 
So if you ain't living on the edge then you are taking up too much room

there is an alternative to leaky gearbox woes just let it all escape and drive with it dry.....i have done so a couple of times.......oops

Hi Markie,

The only seal I had problems with is the seal on the input shaft. If you remove the gearbox from the engine there is a cast spigot support with a seal, a 6mm bolt hold it in place. I did not replace this myself and lost a new clutch after a good run when all was hot .

The problems made worse when you have no cover fitted to the bell housing as the oil atomises and covers the friction plate so you are not aware until it,s to late. The new seal is easy to replace and would recommend covering the splines with tape when fitting a new seal to stop any damage to the new seal on installing it.

Hey Rusty just a tip for your auto slipping clutch, I found that placing the friction plate into a bag off washing powder (Persil etc) this will draw and dry out the plate. Worked for me but will require a few days to work, saves on a new clutch.

Ditto that, you think these little cars are simple until you start messing...

steve do i recall you giving a tip about lifting oil out of driveways using washing powder? i think you may have shares in persil going on the advice you give.
