Update by David S. Wallens to the
Porsche 911 Carrera project car
Jan 31, 2012
While our Porsche engine is out, the work continues.
Our old throw-out bearing clutch release fork is on the right. How much life is left in it? We don't know, so we replaced it. A quarter of a century after Porsche last offered their 915 gearbox, new factory parts are still available.
Before installing the new one, we cleaned and greased its shaft. We also replaced the missing seals.
Replacement just took a few minutes since we already have things apart, instead of several hours for the standalone job.
Add this to the list of jobs we have been attacking while everything is apart on our 1984 Porsche 911 Carrera: We installed a new clutch release fork.
After a couple of decades of use, sometimes these forks will bend before snapping. Other times they’ll simply break without any warning. Either way, clutch action is negatively impacted. We didn’t know when (or if) ours had been replaced, so we ordered a new one.
This fork lives just aft of the clutch disc, so in order to gain access the driveline must be dropped and the engine separated from the transmission. Replacement just took a few minutes since we already have things apart, instead of several hours for the standalone job.
We also cleaned and lubricated the shaft that supports the fork. Some rubber seals were also missing, so we installed those too.
Total cost in parts for this job was about $200. The fork now moves much easier, plus we accomplished a bit of preventative maintenance.
