EJ throw out bearing trivia

G'day all,

I'm keen to know if anyone has several throw out bearing that you could compare.

Reason is that when I did the clutch change last year I lost all of my adjustment thread on the clutch cable - it's relatively new (2.5yo) so over stretching isn't the issue here - the last clutch before it died had plenty of adjustment left in it.

The clutch fork now sits further back in it's little hole that it pokes out from and I'm pretty sure that it hits the edge of the hole when you've got your foot on the clutch as it seems the clutch pedal doesn't go all the way to the floor. My thinking was to pull the gearbox off the engine and adjust the clutch forks pivot ball - turns out there's no adjustment on these.

This got me thinking that my throw out bearing may be smaller in diametre than the one it replaced - problem is that I can't find the old one as it's probably hiding in the bottom of the scrap metal bin that I don't want to empty then re-fill again.

The replacement throw out bearing is 22mm thick from the rear flat plate to the spinning face that meets the finders on the clutch pressure plate.

The other thing I think it could be is the thickness of the flywheel as I got it machined and didn't take any before and after pics to see what the difference was.

I'm hoping to re-gain some of my adjustment, on thought Dad and I have had is to put a spacer or two behind the pivot ball to push it out further.

Anyone else got some thoughts or measurements of throw out bearings? I was trying to find an L series one to compare. If it's as simple as a new throw out bearing I'll just grab one of them and be done with it.

Cheers

Bennie

EJ N/A all use the same throw out bearing. I would look at the step down on the flywheel, make sure it's at the correct depth. Also look at the crush depth on the pressure plate, maybe there is a lot less than factory. I'd also check that the fork is not bent over too much. Like you've done, extra spacers behind the pivot bolt will give you heaps of extra adjustment, so if it's still not there, then something is not right.

Roger that. I'll knock up those spacers and see how we go.

Oh.. I read it as you had, sorry my bad. Yes definately try a 2mm think washer behind.

BTW.. what model car and engine is this in?

Ruby Scoo. EJ22 with EJ gearbox casings and L series internals

The first clutch setup was probably the one from the factory - when I got the engine it came from a Liberty in the PAP yard that had 127k km on the clock. The clutch plate was well used but the flywheel was good enough, as was the pressure plate.

But when that new clutch plate died last August it killed the pressure plate so I had to get a new clutch kit and I also had the flywheel machined due to over heating it a few times in the past while 4wd'n too hard/not properly.

Now that this new clutch kit is in I've lost all of my adjustment at the clutch fork, I think I was pretty lucky to have done all that work and be able to drive it off after it. My clutch pedal doesn't touch the floor either.

I can't remember if I used the EJ or L series throw out bearing - and I can't remember if they're the same or not as I don't have two to compare, or more to the point, if I do have two to compare, I can't find them

I hope this makes sense.

Cheers

The two bearings I have in the garage are the same mate.

Double check the pivot is in the lower of the two holes (gen 2 casing onward off memory) as the upper is for hydraulic push-type clutch fork.

My old liberty had a cable clutch and I don't think it hit the floor off memory, but I still had the standard 15-20mm free play at the pedal...

EJ case with L internals?!?! You finally get your box build done or did you get someone else onto it?

Same gearbox since the EJ conversion - I did that one myself and guessed the diff backlash etc

It's still going well though.

Yeah it's all still there, now I'm getting stung by imageshack to keep my images current, it's not a huge fee but it's annoying to have another payment... I'm three times over their limit in the free account - this is a new fee by the way!

I did take photos of the gearbox work but not specifically of the throw out bearings...

The only things that have changed are: flywheel machined, clutch disc, clutch pressure plate and the throw out bearing. The pressure plates check out as the same size in thickness...
