StStart by putting the top and clam shell into the
service position - remove the storage tray or speakers, carpet and
engine cover - then either purchase or make an engine holder ( this will
hold the back of the engine up when the transmission is removed. - put
both seats in full forward position - remove 4 carpet retainers and
remove carpet - then remove the 10mm bolts and nuts holding the front
inspection panel in place - remove panel |
  
Looking at the front of the engine through the
inspection panel remove the cam covers using a small screwdriver through
the center of the plug (its soft in the center ) and carefully pry it
out -with a 24 mm wrench rotate the crankshaft (clockwise only) until
top dead center ( OT) for #1 cylinder is aligned and the elongated hole
will allow you to insert the pin. You will know this is on #1 when the
smaller side of the cam lobe is facing away from the crank |
 
Now comes the fun part - remove the muffler,
intermediate pipes, diagonal braces, lower tray, rear brace, sway
bar-disconnect shift cables, back up light switch wire, drive shafts and
finally place a jack or whatever you have that is capable of
holding the weight of the transmission ( approx 200#) under the
transmission and remove all mount bolts and rear mounts. pull back and
lower the transmission. Finally remove the clutch and pressure plate (
remove the bolts one turn at a time to prevent warping the press plate)
unless you are replacing it, then just air wrench it off. |
  
Now its time to remove the flywheel ( Porsche
recommends replacing the bolts after each use same with the pressure
plate bolts) Now its time to remove the 2 chain tensioners 35mm wrench I
usually remove the one for Cyl 1-3 first then the crank tensioner - now
remove the IMS cover then the retainer and the LN engineering bearing
removal tool and pool your bearing - BTW you should have frozen the new
bearing with the installation tool so it's good and cold for insertion |
 
AAs stated above the new bearing should have been
frozen overnight for installation - you must align the bearing before
hammering it in place (*** keep in mind when you hammer the bearing in
that the other end of the IMS shaft is position inside the oil pump
housing which is made out of aluminum) you can break the housing if you
hit the bearing too hard - however you must get the bearing past the
retaining groove to be able to install the clip.
THAT's it put everything back in the reverse order - follow specific
torque's for each component and follow all safety precautions
