Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

My '99 996 needs new pinion and counter shaft bearings. Unfortunately the local Porsche dealer tells me that these two bearings require 25 tons of force to press them onto their respective shafts. Is this correct? I live in the Cayman Islands so if this is correct, and they can't find a shop locally with a press, they will have to send the shafts and bearings to somewhere in Florida to be mated. Do these bearings really need that much force for a correct installation and if not are there any other installation methods that can be tried if a suitable press is not available? Thanks

Alternatively you could import a used gearbox from a dismantler in the US. They run anywhere from $2K USD to $3500. I have no idea what it would cost to get it to you. Or go directly to Gboxweb.com and buy a refurbished unit from them.

25 ton press not that big of a press. Most any self-respecting machine shop, boat repair shop, even automotive shop should have one. Here's a pic of a 40 ton press at a nearby (to me....) Porsche dealer service department. Years ago I used to assemble various components that required pressing by heating the part to be pressed on a shaft, like a bearing or sleeve, in an oven (minding not to get the part too hot that any seals or lub, etc. would be degraded) and chilling the part -- like a shaft -- on to which the part gets pressed, chilling the part in a tub of acetone and dry ice. However, in the case of what you are attempting to do, I'm not sure if the above can bring the two pieces to a net temp difference that would allow them two parts to be assembled with no press. Sincerely, Macster.
