Clutch Forks are they all the same

[Dieseler]

I have looked through the EPC a little and see some different part numbers for the fork but my experience that does not mean alot in the Toyota parts world since they use the same parts and change the numbers constantly preceding and superceding each other.

Can anyone who has done a fair amount of clutch work confirm if the Forks are similar in measurements I would assume the length is the same... it is the depth of the fork contacting the pressure plate that i need confirmation if there are different thickness among forks in the 60,61,62,HJ,FJ world.
Also is there different thickness or depth... NOT diameter on the throwout bearings over the years and engine application.

Darn posted this in the morning and it already hit page two where no one looks.
Nobody out there have any forks of various models in their pile of parts they can run a comparison for me.

The only change I'm aware of is early and late clutch forks on the American spec FJ60.

Early (non-spacer transmission) have a tiny hole at the end to attach an external return spring to.

Late (spacer transmission) would not have the hole.

I don't see why any of them would change? All the same transmissions and bell housings? Although I've never seen a diesel set-up.

Hopefully this gets the gears turning for the other guys

There are differences in the early 2f vs the 3f (4/85 - 0n)bell housing and the arm is slightly different as well. The spring hole mentioned above is just one change. The. TO bearing changed around this same time as well as the slave cyl. and it associated parts.

Dyno

Would any of you be able to comfirm the change on bearing was it thinner pre or post change, I am still trying to figure out why my fork rests tight upto the trans bearing cover when dissengauged.
The only 3 things I can think of is:
-Fork thickness at contact point
-Bearing is thicker than original
-Or the flywheel maybe thicker than original

Does anyone know if there is a thickness difference in flywheel from years or from gasser to diesel.
