Clutch set / flywheel combination? (1 Viewer)

[robinvb]

Hi,

I want to replace the clutch on my '72 FJ40. It has the 1F, but the gearbox is a 4 speed (I guess from a '75 or later).

I was recommended by an FJ40 specialist to replace the old 3-finger pressure plate with a later multifinger plate. While installing, I notice that the clutch plate is 1,5cm higher from the part where it mounted onto the flywheel than the old plate. Basically, when I install the clutch and pressure plate, the clutch has around 1,5cm front-back play.

Is this movement ok? Does the new set perhaps require a later model flywheel? Or am I doing something wrong?

The new set is a Nipparts J2002051.

I greatly appreciate your advise! Please see the photos.

Best regards, Robin (Netherlands).

You cannot mix 3 speed clutch components with 4 speed. Flywheel, clutch disc, pressure plate, throw out bearing, its lever and slave cylinder all must be from the same setup.

Only the bellhousing and transmission are interchangeable.

Ok, thank you for your response. My garage thinks otherwise, but I believe you're right.

Best regards, Robin.

'72 FJ40. It has the 1F, but the gearbox is a 4 speed (I guess from a '75 or later).

I’ll just add that the 4-speed came before the 2F. 1974 was a transition year for the transmission and the F engine with the 2F oil system. The engine officially called the F but often called the F.5 or F 1.5.

My 74 has the F.5 and a 4-speed transmission with the 3-finger clutch.

Ah, didn't know that. Mine had an interesting combination of the F engine, 3-finger pressure plate, 3-sp transfer box and a GM 4-speed. After a bolt broke off inside the transfer box, I replaced the gearbox and transferbox for a Toyota 4-speed. So it's not original. Nothing is original on this 40 (incl axle above springs, front moved forward and a lot of other odd conversions). Thanks, previous owner...

Anyhow, I guess it option is to replace the 3-finger clutch with the same.
