POSTING AGAIN AS EARLIER POST TODAY WITH PICTURE DOES NOT SHOW
22 DEPOT HACK
Talk about panic. Clutch pedal stuck to floor in low during parade. Suck with overs forward and in neutral. Had to pull it up with edges of shoes.
Just changed oil to Castrol synthetic 10-40w for motorcycles based on readings. Could that be the problem? Was using Castrol 10-30 and also straight 40w prior to the synthetic change. Only had clutch problem when somewhat cold as at end on inclined driveway. But never constant like today.
Thoughts??? Really don't want to run over girl scouts in next parade in July.
I had problems with an old car changed from normal to synthetic. I would avoid it. Better minds speak up as to why spring pressure on clutch band would not release due to oil??
Your clutch linkage is probably improperly adjusted so it goes up and over center causing the pedal to stay on the floor. Nothing to do with the plates or oil.
How much air pressure in the tires ?
Russ; I think the toggle link between your low pedal and the high speed fork arm on the left side of the transmission cover is just a little bit short, allowing the link to go over center, the Ford repair manual describes how to adjust it. If this is not the problem then your low speed band is adjusted too loose. Brad.
Yikes, doncha hate it when that happens!
What you described is, to me, not a clutch problem but a symptom of low band needing adjustment and possibly adjustment of the low speed connection.
I suppose that with the synthetic oil being more slippery you had to depress the low pedal harder to engage and thereby went over center, but adjustment was to be needed very soon anyway.
Good luck with your project, Bill
Read these links regarding other causes:
Simplest reason for getting stuck in low is if the band is worn enough to allow the low cam to pull over to the flat - if everything else was OK before, re-adjust your low speed band.
Russ, these guys got it. Like Dan Treace describes in Erik's second link (scroll down just a bit to the picture), loosen the jam nut on the right side of the trans cover,
turn the adjustment screw IN 1/2 a turn and try again. If that doesn't keep it from sticking, go another 1/2 turn IN. Lock the jam nut when you have it set. :-)
I like to keep the bands loose on my favorite T and that's my adjustment technique for low. When it doesn't stick down, it's good.
I use FIRM foot pressure to test for sticking down. Mine's almost ready for a 1/2 turn IN again as I'm working with new bands yet.
My car was stuck in low at one time and it was because the cotter pins had not been placed along the clutch fingers when the transmission rebuild was done. I did not do the work, incidentally.
I had similar issues, the cams were worn out and got to the point they were wearing so fast I could not keep the band adjusted.
That only happens if you can push the pedal all the way to the floor.
If the band and linkage is properly adjusted, it will never happen.
Thanks everyone. Knowledge + Experience with a generous amount of Wisdom = MTFCA.
FYI, I adjusted the clutch via the right side lock-nut/tightening bolt 1.75 turns..... Bingo!
Blaster oil the day before then 2 pots boiling hot water and a breaker bar + pipe to loosen the lock-nut this morning.
Thanks again everyone
I am happy for you that you have fixed your car.
Not to be too technical or worse, pedantic, but the adjustment you made is to tighten the low speed band.
It is not the clutch.
1.75 turns is a lot when adjusting a band, usually half a turn is enough. What's the distance between the pedal and the floorboard now when in low gear? Shouldn't be more than 1-1/2" , if more the band may be too tight, causing unnecessary friction?
Think that Russ did OK to get the low pedal back. His later post has the problem of rusted stuck lock nut on the low band adj. screw. If that lock nut was that stuck, bet the low band hadn't been adjusted in a long time, so the lining would be rather thin by now, needing a bit more adjustment.
I'm new to 'T's' but I just learned this myself, , linkage and loose band, like really loose! at least two turns with my fingers to even get the slack out, the trans as been rebuilt but I know very little about them, yet, , yep, panic time when pedal stuck down!
