Just purchased a '98 S70 w/5speed, 2w/d, non turbo, and the clutch slave cyl is leaking. Two mechanics have told me the bellhousing will have to be removed to replace the part, and while it's off, may as well replace the clutch. Not a bad idea about the clutch, but does anyone know if removal of the bellhousing is necessary? Need to save whatever I can at this point. Thanks for any help!!

Re: S70 Clutch Slave Cylinder (hohound)

There are two different types of slave cylinders for your year. Volvo went to the "SAC" release bearing 20 weeks into the production of the 1998 models. If you can take a pic of the slave for me I'll tell you what you have and wheter or not you'll have to remove the slave. If the slave is cylindrical with a piston coming out to a metal bar, then you will not have to remove the bell housing.

Re: S70 Clutch Slave Cylinder (gdogg16)

Not set up to send a pic, but from what you say and what I've seen in searching around, mine is the "gotta tear it apart" variety. There is no lever visible on the outside, just a small cylinder with a bleed valve, and the other end disappears into the bell housing thru a rubber boot, without so much as an attaching bolt. Sounds like bad news, eh? What a stupid arrangement! Thanks very much for your reply, even if it wasn't what I wanted to hear!

Thanks again, Walt

Re: S70 Clutch Slave Cylinder (hohound)

this is the Self Adjusting Clutch slave that requires the removal of the trans.
