911E Sportomatic Problem

[pyorke]

Hi, Got a '72 911E Sportomatic.

It's been sitting for a few months waiting for an oil tank.

Just fitted it but when I tried to start it the throttle linkages were sticking open. Freed them out now and they seem fine.

Problem is the clutch doesn't seem to want to engage. If you put it in neutral it seems to be fine. Touch the gear stick and the clutch operates and the clutch is depressed.

Put it into gear and let go of the stick and it makes a sound like the clutch is being released, but it stops driving the drive plate. I haven't seen if it is the clutch or the torque converter that is not driving yet.

Is there any special procedure for bleeding the torque converter after changing the oil tank / changing the oil.

Oil level and oil pressure is fine.

Thanks for any help or advice.

Paul.

I've never had to bleed the torque converter and I've never heard of anyone else doing that either. Without seeing it the usual procedure is:-
1. make sure the contact points at the gear stick are working properly, ie not shorting out and making the clutch arm move, you can hear the diaphragm 'clunk'.
2. Get under the car and observe what is going on there, the clutch actuating arm can bend if it meets resistance. If it worked ok before the lay up , it suggests something needs freeing up and lubricating, a sticking clutch component sounds possible? Hope Bernie checks in with more help.

Hi just back from France today! not shure whats happning on this if it worked before it should still be ok! As Bones has said check the contacts at the base of the gear leaver and check that the servo is working, also check the conection on the solonoid. You can adjust the solonoid but it dosent sound as if its that! hard to say from this far away!! Its imposable to set clerance without droping the engine. try the contacts and as Bones said listen for the servo klonk,if no joy report back Regards Berny.

As others point out, no special proceedure that i can think of. But sorry to quote the obvious........do rememeber the sporto takes extra oil when doing a full change, can't remember exactly how much now but 13 litres seems to ring a bell.

Takes about two litres extra Laurence, so spot onish [] but I don't think that even two litres less short of max level would make a difference to the torque converter engaging, sounds like lack of use has led to something 'glueing up' if nothing else becomes obvious.

Yes i think your right. My dim and dark memory on this is...torque convertor is always engaged except when the clutch is depressed to change gear(the convertor actually acts like the clutch and the clutch acts a bit like a switch). Correct revs causing the torque convetor to lock solid and create drive(the bit everyone curses for the time delay). So either the clutch is out (not engaged) or the torque convertor is not locking. Worth checking the vacuum lines in case one got disturbed when the tank was changed or as you say , something gummed up (solenoid?).

It's a few years since I ran my car with a sporto box but did so for nearly ten years. I remember, if the adjustment screw on the control valve body is screwed in too far, it will give a soft and slow clutch engagement. Screwed out it will give a fierce and very fast engagement - sometimes with a bang, on a cold engine. If screwed in past the 'soft engagement' position you can engage a gear and just sit still without the car moving, but still in gear.
Maybe your control valve needs resetting with an engine at normal running temperature. Try turning that screw outwards quarter turn at a time.Handbrake firmly on if the engine is running. (The screw is under a plastic cap on the valve body)
