SM105K's SHO BIBLE/BUILDS/LIFE

[SM105K]

Lexus Update: Worked on the Lexus this weekend. I knew something came apart in the clutch a couple of weeks back. I suspected that a puck came apart and it welded itself to the flywheel. The clutch pedal stuck to the floor which helped my hypothesis. So I dug in.



With the trans being so dirty and oily I was fully expecting a rear main seal leak. However, that wasn't the case. I think it is a valve cover. So I will be looking into that as well.

If look you can see two of the pucks did exactly what I thought. However, they welded themselves to the pressure plate and the flywheel. Good times. Lol.






I drained and cleaned up the transmission. Still have to do more work to it to add the slave cylinder as well. Also need to research and see what is the newest and best transmission oil to run in the ole R154.







I needed to pull out the old pilot bearing. I used a piece of bread, an extension, and my dead blow hammer. Way easier then the slide hammer tool, or packing with with grease. Clean up was a snap.





New flywheel fastened with ARP studs.


Got the new twin disk set up with the new pressure plate installed.



I still have to remove the master and slave from the car. I have it modify the new Wilwood master to fit the IS300 pedal. I bought a complete kit from a MK3 Supra and knew I would need to modify this. Shouldn't be too difficult for my buddy Kyle. Also going to have him add a pedal stop as well.

So yeah. Hopefully I can have the Lexus back on the street next weekend.

Your old clutch plate looks like the one I was using. Interesting way to make flatbread, but is it marketable?

I was looking for marks or something to tell me what clutch it was. My buddy said he vaguely remembered it was a Tilton. Haha flatbread is pretty funny. Marketable? Probably....not. However, it was really easy getting that pilot bearing out.

out of all the clutches I've done I have never seen the bread trick. Always used a slide hammer. learn new shit every day.

I have never seen the bread trick either. I have used a slide hammer as well. I was browsing Youtube looking for some tips and tricks, and one of the guys used bread and grease. After the end, he said, you could probably just use bread and clean up will be really easy. So I did, and he was correct. It was super easy too.

 

[Bluezone]

I had heard of it but I've never actually seen anyone use it. Very cool. Yeah I think that's the same brand clutch plate I had. 10 years ago, so don't quote man.

Lexus Update: I dropped off the new clutch master and pedal assembly off so my buddy Kyle (he built my exhaust for the SHO). The holes don't line up, so he is going to do some massaging of the holes so we can stick them together. Of course I broke the neutral safety switch during removal...lol. SO I will be purchasing another one as well. He is also going to tackle a pedal stop for me as well. I plan on installing the new slave bearing and trying to stab the trans back in today. Wish me luck.

Easiest way to explain it.

Thank you SM,

That bread trick is very cool.

When I worked as a truck mechanic I made a tool for removing those bearings. I took a large 3/4 bolt (I think that was the size) I then took the nut and made it acorn shaped on a grinder. Then I slipped the acorn nut through the pilot bearing hole, turned it to align with the bolt and used an air gun to push out the bearing.

Last time I worked on a manual it was one of my Mustangs. I've seen alot of burned out clutches (not sure why, never powershifted above 6500) but this one you've got is the most radical I've ever seen. Nice work doing the tearback, attention to details keep the 'klunk and coast to a stop' gremlins away.

Yeah, really didn't like the clutch that was in it to be honest. However, back in the mid 2000's that is what was being offered. It chattered a lot, which could have been a tell tale sign of it's impending death. If this SPEC twin disk is anything like my McLeod twin disk, then I will have a lot of fun and we will find the next weak link. LOL.

That's pretty neat.

Lexus Update: So I had to take a mental break from the Lexus. It has been a complete fight. It started with fighting with the transmission. Stabbing a twin disc isn't the easiest. However, in the past I was able to wrestle either a T-5 or a T-56 into place without much difficulty on jack stands before. However the R154 in this car was a complete bitch. I even had a buddy come over and help me, but no dice.

I had to go to a hardware store and get longer bolts and literally had to bit by bit walk the transmission on. After two hours, it was flush and not binding. I was able to get everything back together. I installed the new Wilwood Master Clutch Cylinder and lines. I bled the system and started the car. While in the air the transmission shifted clunky but it shifted. Once I got it on the ground, that was a different story. I could not get the car to go into any gear. I adjusted the rod all the way on the master and finally got it to go into 3rd gear. That being said, I am not getting any pedal pressure until about half way down.

The clutch kit I bought is for a MK3 Supra. So the adaptor that connects the master the car is really thick. I looked online for other adaptors for the IS300 and all of them are really thin. Since my pedal doesn't feel like it is engaging even with the rod extended out, I think cutting the adaptor will fix the situation. So I cut it in a little less than half. However, I haven't had any motivation to put it back together. So when I do I will update. I feel like a #metoo victim... because this car is abusing me.

I had a lift and transmission floor jack for my last few tranny pulls, so I'm spoiled, but got them all out and back in by myself. I'm trying to understand what was binding when you tried to put the trans back in. Splines on the input shaft when they engaged the clutch plate? Pilot bearing with 3 microns of clearance? Throwout bearing engaging too far out? I'm worried that if you had to use longer bolts to coax it in, something is binding that will affect function. The trans spun freely when you had it out, correct?

It was the input shaft going through the clutch disks. I just wasn't able to push it through. I just think it was a case of not being able get the correct angle with the correct pressure. Once I evenly starting putting pressure on the belt housing (via longer bolts) it went on pretty easy. It was just tedious. Everything else was a breeze.

I just think the adaptor is limiting the pedal through, thus not allowing the throw out bearing to extend enough to disengage both disks completely. I will post pics about why I think the adaptor is the main cause. If it isn't, then I will probably have to add spacers behind the throw out bearing (which SPEC says shouldn't be the case)...which means the trans comes out again.

 

[FrankK]

Did you try sliding the clutch plates on and off the trans spline before you mounted to the flywheel? Just to make sure they didn't bind anywhere?

I did. They were tight, but they didn't bind.
