Rullingen Posted May 25, 2018 Share Posted May 25, 2018 I have a 2007 Roadsport with and EU3 1600 k series married with a type 9 2.8 Ford gearbox. It’s done only about 21K miles.On the way home from Spain last year driving up through France I started to get clutch slip at max torque; in top gear. I got it home OK and haven’t had time to address the issue until now.I separated the engine and gearbox. The clutch looked clean and intact, but there was a light coating of oil across the whole of the inside of the bell housing. There was no evidence to show that this had come from behind the flywheel. When I separated the clutch from the flywheel I found the friction plate to be partially saturated in oil but very little on the clutch cover other than a small amount of oily clutch matter that had been thrown off the friction plate. The car has never deposited so much as a drop of oil on the garage floor.When I read accounts on these forums of oil leaking into the bell housing they all seemed to focus around the seals between the gearbox and bell housing, and the selector shaft in particular. I haven’t seen any that suggest a leak from the input shaft, straight on the centre of the clutch, but this seems to me to be the obvious source of the leak given that if it were at the face of the gearbox then the oil would just run down the inside of the bellhousing and find it’s way out. I can’t understand how it could end up on the clutch friction plate.Please, if I’m missing something crucial, could someone explain? Link to comment Share on other sites More sharing options...
oilyhands Posted May 25, 2018 Share Posted May 25, 2018 There is an oil seal in the nose of the cover that supports the first motion shaft, this could be leaking, which side of the plate is contaminated? It could be the main crank seal.Oily Link to comment Share on other sites More sharing options...
Rullingen Posted May 25, 2018 Author Share Posted May 25, 2018 Pretty sure it's not the crank shaft seal. It's bone dry on the engine side of the flywheel. All of the plate is contaminated. Is it a strip down job to change that seal? I'm struggling to find literature on it.https://photos.app.goo.gl/Y4v5er1mpg9T8Xu43Rob. Link to comment Share on other sites More sharing options...
Rullingen Posted May 25, 2018 Author Share Posted May 25, 2018 I've now got the seal out from the input shaft tube. It's not damaged. It's a SIMBO 28 x 40 x 7mm seal. Not heard of SIMBO before. Not sure on quality. I shall change it anyway.I also noticed it is possible to rock the end of the input shaft up and down 2.5mm from extremity to extremity. I'm guessing this is normal and not indication of a worn bearing since the other end of the input shaft sits in the engine crank shaft.I also now understand the issue with the selector shaft leaking oil, although I didn't see any evidence that this is the cause of my leak.

Jim 123 Posted May 26, 2018 Share Posted May 26, 2018 From your photos, there appears to be rust on one segment of the flywheel, and the lower bell housing looks as though it has had contaminated water collecting in it. Has the car sat in water at any time? Link to comment Share on other sites More sharing options...
Rullingen Posted May 28, 2018 Author Share Posted May 28, 2018 Definitely not Jim. In fact it has only seen rain two, or maybe three days in its life.Rob. Link to comment Share on other sites More sharing options...
