6MT throwout bearing and clutch system shenanigans

This thread is one of many on TW regarding these issues. As some may know. I’ve had a “less than good” experience with the whole clutch setup in this truck. From rev-hang to slippage. Squeaking throwout bearings to leaking hydro bearings. TSB parts, pedal squeek, etc. it’s all just a huge pita and it’s really got me down on a vehicle I really enjoy otherwise.

Herein will be my ramblings on the matter...

Sister thread to this one on what was going to be regarding transmission internals is here. As it turns out, that thread morphed into an RC62F swap.

 

So, A lot of people have asked for me to list what parts I used to make all of this work. Here ya go.

Pedal parts:

31301-35270 x 1 Fj clutch pedal

31321-52010 x 1 Pedal pad

90386-14015 x 2 Pedal pivot bushings.

90387-08160 x 1 Collar shaft for pedal pivot. You probably don't need this unless yours is badly worn. I re-used mine.

90389-06055 x 1 Bushing at the top of the pedal for the turnover spring

90541-06036 x 1 Pad where pedal contacts the upper clutch switch.

47131-47070 x 1 Pad I used to contact lower pedal switch.

31453-35010 x Clevis I used to eliminate the damper thingy.

90249-08018 x 1 Pin

90386-08033 x 1 Pin bushing

90206-08001 x 1 Wave washer for pin

90468-15006 x 1 Clip pin to retain


Release bearing parts:

Tilton 60-612 Bearing kit w/o piston and bearing. Tell them that you need this kit with the 61-628 threaded sleeve.

Tilton 62-612 Piston for 40mm i.d. bearing.

Toyota 90363-45013 x 1 Release bearing suitable for the OE clutch with 60mm opening. Will have to source from overseas. I ordered mine off of ebay. It shipped out of Dubai. Took 3-4 days.

11183-62010 x 2. I used these half moons to seal up the 34mm hole where the original release cylinder was.

 

Pics of stuff I bought.

 

RA60F bell housing acquired for measurements and test fitting.

OE throwout bearing.

 

Is this a new OEM RA60 bellhousing?

 

RA60F. Yes.

 

How much did that hell housing run you ?

 

I don't want to be the bearer of bad news but you do know that the whole transmission has to come apart, starting at the rear side, to get that thing on? Neverless, I've followed your travails and you probably already know that. Sorry your hydro bearing has been such a pain...

 

Yes. I’m aware of what needs to happen to replace that. I do not intend to. My existing one is fine. I ordered this thing to get some measurements and to test fit things.

I do however intend to dive inside of mine when it’s out. I have a slight grind going into third that I want to address. I’m also contemplating a swap-out of 6th gear and the countershaft to the .799 OD of the FJcruiser. But, that’s another thread.

 

PM me.

 

d have done

Wished I had been following you a bit closer as I have one and could have done the measurements for you.
I have been into a couple of these now and on your '08 the shift fork for 3rd is immediately suspect (it is crummy cast aluminum). That and the syncromesh keys and springs on the respective clutch hub have been a recurrent failure point (later revised). And naturally the 3rd syncro and its bearing (slop develops).

If you get to the surgery stage I would invite you to PM me before spending any money on parts as there have been a boat load of part revisions quietly upgrading the transmission over the years. In addition there have been two revisions of the entire transmission, for three total versions.

For a long time on this forum I have advocated that IMHO it would be a better idea to find a '13-'15 transmission instead, and preferably a late-'14(from March 2014 on) to late-'15 as you will get the upgraded counter shaft.

 

I love a good ramble...

 

That's good info.

 

You and I will be talking for sure sir. Thank you.

I want to iron out this release problem first. Then I'll get into the guts of the thing.

 

I'm looking at another OEM bearing that might work in place of the stock unit. It's slightly larger in some areas, though it sees use with a 275mm clutch. LMK if you have any interest.

3rd gear bearing slop can be reduced/eliminated by cross drilling the main shaft so it receives oil from the shaft center... though I should ask, is the RA shaft center drilled like the RC? We can move this discussion elsewhere so we don't muddy the T/O bearing info.

 

You should consider making this into a thread all about this throw out bearing issue, since you clearly have some experience with it. It would be cool to have one thread with all known answers, like what causes the problem, and all of the different ways you can “fix” the issue, even though we know none of them work. I would love to start such a thread but I don’t know much about this issue yet, I just started researching it.

 

so far i like the .799 of the ra61f. been running it for about 40k now. i will have to make some time to go in and do 4th synchro for some grinding. i have a bad feeling by the time i get in there i will have to do the gear as well. but if you make a thread for that ill add more.
i do have the clutch masters hydro bearing. starting to get squeaking again in the cold.

 

Yes, please. Do tell on the TO bearing you’re looking at. I’ve been researching for days now. I’ve found few prospects from vehicles that weren’t imported to the states. And they’d need to be modified.
