Slave Cylinder Seeping

How complex (and expensive) is it to repair a seeping slave cylinder on a 348?

 

easy to fix..expenisve to replace..about a g-note by the time your done.

 

When would you need to replace it instead of just repairing it?

 

It all depends on the version of the slave you have. If you have a aluminum version best thing is to replace as an assenbly. If you have the older cast version you can just repalce the 4 seals and the 3 input shaft seals and be done and outa there for less then 200 bucks.

 

Thanks. I'm assuming a 1989 348TB would have the older version. Would you trust this job to a shop that is not a Ferrari specialist? There are no local Ferrari shops.

 

If its just the 4 seals, any competent shop should be able to do it.

 

I wouldn't necessarily assume that -- it all depends on if a Ferrari dealer retrofit the clutch at any time prior in the car's history. They are very simply to distinguish: the old bearings are black cast iron looking. New ones are dull/anodize aluminum looking.

Thanks, No_Doubt, for the link to Club348.com, which I was not aware of. As a 348 Newbie, I'm actually assuming that my problem is in fact a seeping slave cylinder. The symptom is leakage of a mineral oil-type fluid in my garage after I drive my 1989 348 TB. The "slave cylinder seeping" cause was suggested by Norwood Performance. The brake fluid/clutch fluid resevoir level, however, does not seem to be low. Does this seem to be a slave cylinder problem? There is also some occasional difficulty in getting the car into various gears, although I very rarely drive it, due to concerns about what may be the problem. Thanks again for the various replies.

 

FYI, if the car has the original cast iron bearing & housing, there are only 3 internal seals for the bearing. The aluminum bearing & housing will have 4 internal seals.
Then there will be the large O-ring (p/n 143178), the 3 nylon rings (p/n 137249) an oil seal (either a 131651 p/n or 151822 which isn't a traditional oil seal, but more like the shift shaft seals of the 3X8 series), and two tiny O-rings (p/n 121813 or 166432).

 

Thanks very much for the parts numbers.

 

Are there any other potential sources of a clear petroleum fluid that are nearby, like a brake line, lose hydraulic hose to the slave, engine oil, gearbox oil? I am a vintage guy, so not familiar with this model.
