Clutch Disc Orientation

[mhdsummers]

Before I bolt up the tranny, I want to make 100% sure I have the clutch disc in correctly. I goes like this right?

I don't remember, but I do remember looking at my FSM when I put mine together.

 

[Ian Rogers]

it only fits one way

 

[mhdsummers]

This is for a 78 FJ40.
I am pretty sure it can fit either way.
Can anyone verify I have it installed correctly?

 

[Mace]

that is correct,
If you install it the other way the hub wil hit the flywheel bolts before the disk contacts the flywheel.

Course, you CAN bolt it together this way...


Also, clean the living hell out of the pressure plate and flywheel (but not the clutch disc) with brake cleaner before assy..

Thanks Mace.
I thought that was correct. I have all new components and I had the flywheel resurfaced. I cleaned up the surfaces pretty well with brake cleaner.

The first picture shows which side of the clutch disc is the flywheel side and the second picture shows the opposite side, or the side that faces the pressure plate/transmission when installed.



FLYWHEEL SIDE

PRESSURE PLATE/TRANSMISSION SIDE

If you try to install the disc the other direction, it will interfere with the flywheel bolts.

I'm guessing this is what happened. My "expert" Land Cruiser restoration mechanic calls and says there is a problem with my clutch while they were swapping in my new 2F engine. I go over there and he shows me the chewed up flywheel bolt heads and the shiny, chewed up clutch disc springs (other side in the attached picture). Two years ago when the vehicle failed inspection the day after I bought it, one of the items squawked was the leaking transmission and transfer case. Of course an old gear head knows that if you are pulling the transmission you put in a new clutch. I was ordering parts from the USA. I bought the complete drum brake kit and clutch kit from CCOT. I have never been happy with the clutch operation. The vehicle sat in the shop for some six months, when it came home it leaked. I ask what is up, they couldn't get the seals and gaskets, so they put it back together!?! So I order the Terrain Tamer kits from CCOT, and I order synchro rings from toyotaoverstock.com. They send me a 3spd and a 4spd ring. Aaaarrgggh. Vehicle comes back home sans transmission so I can re-wire the vehicle while waiting for parts, again. The second time through they also found that the transfer case shift fork had been repaired and needed more work, I ordered another one from the States. While I had The Beast home I wanted to pull the clutch, flywheel and bell housing to verify that the flywheel had been turned per my request when the new clutch was going in. Mind you, I have less than 50km use of the vehicle at that time. I decided I wasn't confident in my ability, tools, equipment to do the job so I didn't pull it. Now it has been in service for over a year, 8,000 miles and find out the expert installed the clutch disc backwards, chewed up the bolts, scored the flywheel and chatter marks galore. One thing for sure, it doesn't matter where in the world you live, you just can't trust anyone else's work.
