clutch disk backward?

[65swb45]

Did you perhaps have your flywheel surfaced? I noted from your sig line that your vehicle is spec'd as a 71, which would run the three finger pressure plate and early, recessed face flywheel.

When those flywheels are resurfaced, it is a TWO-STEP procedure, requiring them to cut down the MOUNTING face of the flywheel where the pressure plate ATTACHES, as well as the FRICTION face. If they only cut the friction face, you may have TOO MUCH ROOM between the flywheel and pressure plate, allowing the disc to slip.

If this is your scenario, you will need to remove the flywheel to have the mounting face resurfaced.

How is the fork in relation to the pivot?

here's my setup:

1971 FJ-40
1977 2F
4speed bellhousing, flywheel, clutch disk & pressure plate, fork and bearing
1971 slave cylinder
4 speed tranny and t-case (not the split type)


The disk is new but the flywheel and pressure plate are the same I was using.

bull How is the fork in relation to the pivot?

I will look at it but I think it's o.k. since I can rotate the bearing with my hands when there is no pressure on the clutch pedal. Maybe this is where I am making a mistake

I'll be back thursday morning , Thanks to all for your help

Try putting the trans in gear with the engine off, jack up the rear axle and turn the drive shaft by hand. If it turns, you may have a transfer/trans problem, not a clutch issue

"The disk is new but the flywheel and pressure plate are the same I was using."

Looking at Marks post, there seems to be a difference in 4 sp and 3sp flywheels, could the three speed flywheel be recessed, as Mark stated, enough to keep the inputshaft splines from reaching the clutch plate?

 

[Toyo FJ40]

He's using a 4 speed flywheel and pressure plate. The clutch splines are the same for 3 speed or 4 speed. So did you ever see this trans work? I would do what plowboy said and have someone spin the tire while it's in gear and check to see if you can see the clutch plate slipping.

I'm not at home right now but at least I can go on MUD through a PAINFULLY slow computer Anyway.... No I have never seen this tranny and t-case work, but I'm pretty ( I was pretty sure ) that I tried it manually.

Plowboy, thanks for the idea! I'm gonna try it when I get back home.

o.k. here's what I found:

Maybe I have the same problem that Bull had....even if I can rotate the bearing with my hands? I could not turn my rear wheels because I also found out I had a brake binding issue, and my girlfriend is not strong enough to do it
The brake binding is not that hard......

So, what do you guys think of the fork position? does it looks good?

 

[D'Animal]

Fork looks like mine in my 76 FJ 40, 74 FJ 45.5 and my 86 FJ60.

Mine all have the fork coming out the passenger side. How did you get that picture? Or is this something that changed before my vintage.

 

[froggy]

The fork is on the driver side, because I wanted to keep the 3 speed slave cylinder setup that is on the driver side on a 1971. What i'd like to know is : should the bearing's hub be closer to the transmission?

The brg should not contact the fingers on the pressure plate.. here's a handy adjustment guide.......

 

[froggy]

Here's an update.... Looking at the clutch bearing, I found out it was still putting pressure on the pressure plate. When I tried to adjust the slave cylinder, I found out that the rod was bent and the fork was jammed. I changed the rod, look at the adjustment tried it back and it jammed again, and it did bend a liitle ! When I push on the pedal, the disk releases but after that, the slave cylinder does not come back all the way in... The fork moves freely on the shaft. The spring is working, but I don't think he's supposed to do this job antway... Is it possible that I broke the pressure plate when I removed the tranny

This 4 speed convertion is really a PITA

Do you have the return spring on the slave cylinder? Without the spring it won't return all the way and it can pump up with the pedal and over extend.

Did you watch the fork while someone pushed the pedal to see if it was binding on anything?

look at this...

I think that the later model slave cylinder (4speed) have a bigger threaded nut (the one with the round end) . The one I had was going through the fork hole and was binding when I pushed the pedal. At first, this setup looks o.k. but when working, I could see it was not good. I tried this just to be sure I was right

And it's working perfectly Tomorrow , I will fabricated a new threaded nut at the shop. Finaly , I have a working 4 speed Land cruiser!


Thanks to all

yeah looks like the fork was bending the rod.
