Tilton twin disc is a beast to release. I can't see the stock system lasting very long if people were having problems with a CM unit even if it was due to constant pressure on the system.

Looking to upgrade at least the master cylinder but was wondering if I should step up to an HRB if Tilton can hook me up with compatible goods.

I've been reading about CMS bore size being a factor and that the pedal travel needs to be carefully set to prevent over-travel of the HRB, but I didn't see anything about it helping with pedal effort.

Anyone with HRB experience have any suggestions or advice?

My damn throwout bearing is making some squealing noises right OOTB so I'm going to be taking the transmission out again and if a HRB will help, I may just step up while it's out.

Thanks

why is the throwout bearing squealing? have you adjusted the pedal??? I would think the tilton kit is taller than a aftermarket kit making it ride the throwout bearing...

i remember reading something about a master cylinder which was compatible for our cars which reduced pedal travel by 50% or something like that.

Omni Power Master Cylinder

I don't know why it's making noises and I started pulling it apart yesterday and will have the tranny out today.

I have the pedal set with a bunch of freeplay and it doesn't make any noises until it makes contact with the fingers. The clutch also disengages, just doesn't sound good.

While I was in there, I was wondering if it would be worthwhile to go with a full hydraulic unit.

I am also going to look into getting a larger bore CMC. I'm not sure what the Omni unit is but the Tilton's have specifics. May need to fabricate an adapter plate if the mounting points are different.

My primary goal is to have a lighter pedal. Bmeyer said his left leg was getting bigger and I see why now. Driving in the city would be a chore for sure.

Lol. Well good luck then and let us know what you do.

Wilwood makes universal CMCs in various bores, also.

I believe a larger bore CMC will cause the clutch pedal stroke to decrease and the driver force to increase.

KN_TL

iTrader: (3)

That's correct. The same stroke with larger bore means more fluid transfer iwhich results in faster transition at the slave. Also reading that it will make the pedal effort worse.

Found that Tilton makes a HRB for B series Honda's that fits over the pilot tube. It's the same size as our tube but I have to do some measurements of the clutch fingers to the back of the bell housing to make sure there is enough throw for it to work.

I got my tranny out and I can't see anything that could cause the noise. I thought maybe the throwout bearing was rubbing on something but the fingers have marks on them exactly where it should be and the disc isn't damaged at all from any over-traveling throwout bearing.

what type of noise is it making? when does it happen?

KN_TL

iTrader: (3)

It's a grinding noise that seems to come on as soon as the bearing makes contact with the fingers.

KN_TL

iTrader: (3)

Bert, do you know what the throwout bearing looked like?

Does it have a cone shaped end to it?

I've done some measurements and the HRB is going to come up short. I am going to go ahead and buy it and then take it to a local machine shop to get a spacer made.

Which throwout bearing?

KN_TL

iTrader: (3)

The one for the twin disc.

I just did a bunch of reading. People are mentioning plate rattle.

I wonder if that's all I am hearing?

i had a huge dilema with the twin disc. ill get into detail with a pic of what happened later. theres a lot of speculation of what may have happened and still some unknowns.

basically i chewed up half the spines on one of the discs. kn, if u want, pm me your number and ill call u. i would hate for u to have the same problem. at this point, it is unknown whether or not im the only that had, or will have the problem

libert69

iTrader: (7)

yes its cone shaped. the bearing used in the kit is a oem tl bearing but its modified to fit the new setup.

check the turbo tread for the clutch problem i was talking about

KN_TL

iTrader: (3)

Got my kit today and the bearing face to finger clearance without a spacer is 6.5mm. The instructions say the clearance should be .200" or just over 5mm so I am going to give it a go without any modifications.

The heat finally broke up here so I'll be working on it tomorrow while the temps are back in the high 70's!!

Yikes, getting nervous now

KN_TL

iTrader: (3)

You'll be fine as long as you install the discs back to back instead of facing them in the same direction.

Did you also see that these are supposed to be tougher than the ones I have?

pearlUA7

Haven't been on Tilton in awhile, I'll check her out.

Quick update:

HRB is in and reduced pedal effort by about 1/2. Still stiffer than stock but will not be as big a beast around town. I had to weld a stop to the pedal as the top switch didn't have enough adjustment to bring the pedal off the floor.

The installation of the master cylinder itself was easy because the adapter fit perfectly. I had to cut the length of the plunger to make it work. The pin to the pedal was identical in diameter. The pain was finding a location for the tank. I had to relocate my under hood fuse box to make it work.

Engagement is definitely different and even shifting gears is a new adventure but not as bad as I thought it would. Might still consider installing the flow control valve.

Running Redline Shockproof right now. The shifter is noticeably stiffer and I haven't driven enough to see if my 3rd gear issue returns.

The HRB is a pricey upgrade but it was worth it.

I finally got my car back on the road with the 6speed trans working. some how, my clutch pedal feels a lot more responsive and has less travel. Could be the Pedal adjustment and the Rsx Master Cylinder thats making my pedal much stiffer and engages the clutch with less effort.

If the CMC is a larger bore, it will move more fluid so the pedal does become stiffer.

KN_TL

iTrader: (3)

Finally getting some time on the twin disc and still getting used to the reduction in rotational mass and the on/off characteristics of this clutch, but with the HRB, it makes it so much more drivable.

I was worried that I was going to hate driving it with the new clutch but I am changing my mind. If you can afford an extra $500, it is a worthwhile change.

On the other hand, I am experiencing 3rd gear misses with the RedLine Lightweight Shockproof.....So I'll have to decide if I want to go back to the GM stuff or do a gearset replacement.

libert69

iTrader: (7)

what does 3rd gear misses mean? popping out of gear?

KN_TL

iTrader: (3)

It takes more effort to get it into gear. Was really bad on the original fluid and was totally fixed with the GM stuff. It's now somewhere in between.

That reminds me, do you have an extra set of tranny internals?

libert69

iTrader: (7)

im using the redline mtl and havent noticed any issues.

yes i have spare shafts, gears and syncros from a type-s..need something?

KN_TL

iTrader: (3)

Did you do anything to the used tranny that you installed? I am one of the lucky ones who probably could use the 3rd gear TSB but it's not so bad that the dealer will address it. So if I do anything it'll have to be on my own.

I'm not sure what I want to do at this point. I may hit you up if I need something.

hey kn, did you talk to rodney about this? my clutch and flywheel is still on backorder from the messed up batch the guys ran. happend to libert too. you may wana check in and make sure you don't have the same deal

KN_TL

iTrader: (3)

I am one of the first to get this clutch, just took my clutch a while to burn down enough to replace it. So I don't have the same issues as libert69. I checked all of the clearances and they are fine.

xSilver_Bulletx

Hmm if you have freeplay the TOB shouldn't be making any noise. If it started grinding then it's too late and it's gone. Mine was making noise for a while and I had the pedal readjusted again which made it go away. I'm not running a twin disc setup but I'm running the clutch masters fx300 clutch

KN_TL

iTrader: (3)

Turned out to be plate rattle. It's my first twin disc and after searching, found many youtube vids with the exact same sounds mine is making.

pearlUA7

breaking in period sounds like its almost over for mine, chatter and squeaks but its not bad at all. everythings holding up good and its super easy to drive. might look into this hrb... might, ive been driving daily and in traffic and still love it.

pearlUA7

KN_TL got any issues with first gear? minor issue, first popping out on a level throttle (minor = happens maybe 2 times a week type of thing)

KN_TL

iTrader: (3)

No issues at all.

My third gear is fine as well. I think it was just getting my foot in sync with my hand

Loving this setup except for the plate rattle.
