FYI: W58 slave cylinder differences

[projectsupra]

Just a little FYI for anyone else having trouble with a W58 slave.
Long story short JZA70 clutch master and W58 OEM slave both failed un-spectacularly.
Rebuilt JZA70 master is perfect now, however I purchased a new slave from Advanced (should have went to Toyota?). Come to find out it's almost an 1/8" larger piston than OEM, no amount of adjustment would fully disengage my OS Giken.
Picked up an awesome (and cheap!) PBR slave, custom SS braided line, and couldn't be happier. Plus now I have three different length slave push rods to choose from for some reason.
And here's a pic of my dirty underside just because.

Clutch master and slave are two parts that it's worth buying from Toyota. The parts from elsewhere seem to last about a year of daily use. The parts from Toyota last 15+ years under the same conditions. Well worth the extra cost IMO.

Hm, didn't think the OS clutch was ever intended to be used with a W58.

But anyway, post the 3 lengths of push rods you have, may be of some help to someone in the future.

You're preaching to the choir, mine lasted 22 years. Toyota would usually be my first stop however the local dealership is terrible, no time to order online and wait either. Besides, the quality of this PBR slave appears on par or better than the OEM, and under $20.

I'll see if I can get a pic of the rods, over a half inch difference in those. My TS2B OS技研 is bolted to a 1G-GT BTW.

Damn. This is probably why my clutch engages right off the floor. Cheap slave cylinder FTL.

What's the W58 slave cylinder bore supposed to be anyway?

Hi Projectsupra, I tried sending a PM but your mailbox is full.

Could you tell me the part number for this slave cylinder as I am looking for a bigger-than-OEM bore diameter to suit a W58.

Thanks.

I thought w58 clutches were the same as the ones for the r-154?

Believe they share a disc but not the PP...push vs. pull, etc.

 

[projectsupra]

Sorry, don't have the part number for the old Advanced slave cylinder that was too large, but I do still have the slave cylinder.
I believe the PBR was W0133-1630185.

Got a URL to Advanced?

I'll try and chase it up, as a bigger-than-OEM (for W58 anyway) spec will solve my problems.

Same thing happened to me, went back to oreilly and ordred a different more expensive brand called Beck/Arnley..... Right off the bat I saw it and it looked 20X better than the one with the long push rod. I'm happy with it ...... It prob cost the same as an OEM one thou .....

Having a little trouble with mine as well, could anyone chime in on this? I have a cheapo slave and my clutch refuses to disengage completely, even after being adjusted, but it only started recently and I have had this slave for a while. I measured the bore to be .874" and it has an anodized blue piston inside. Anyone have the measurement for a stock slave?
