clutch slave cylinder spec's??

Does anyone know the service limits of the clutch slave cylinder and piston? Or even what the spec's are on a new one? For my on-going project in 'launching clutch'.

Nope. I thought that was a little wierd. It just says clean and inspect. Then reassemble.

Well, that's cool, but doesn't really help me. Properly working oem is fine for me. I ordered $64.00 worth of cups, seals, springs and new master piston. Time will tell, but I'm sure that my clutch system will be fine.

I've got 35.55 on the piston, 35.68 on the cylinder. The action is very smooth when I slide the (cupless) piston in and out of the cylinder. Feel's ok. If I cant find spec's by the time the part's get here, it's going back together and I'll just runn it and see how it is.

Really wierd that those numbers are this hard to find. Maybe someone could measure a brand new oem?

the aftermarket ones are a larger piston so easier pull over the hard OEM

if it were me i could have sold you used OEM whole clutch slaves for $10 each as they are a dime a dozen and the same ones used on all hondas since at least 1988 til now

measurements of what?

the clutch slave is the most easiest mechanical devise i have ever seen, there is nothing to measure. there is a 35mm piston with a spring and it goes back and forth and has two O rings to stop fluid from passing. there is literally nothing that can go out of spec and $1's worth of new O rings every two decades is all you need to rebuild it if that.

not trying to be a dik just help you move along to where you are not wasting timne for naught.

ding, ding

that is because there is nothing to do except clean them and then reassemble them

There is no metal to metal contact and the springs last forever so replacing the rings (if needed) is about the only thing you will ever need to do with them
