6. Clutch Replacement TIPS (REMOVAL)
1. Drop the exhaust manifolds and release the exhaust system from the two transmission hangers and differential hangers (Or drop exhaust pipes after CATS only). Drag exhaust out of the way.
2. Place jack under oil pan with 2x4 between oil pan and jack plate. Jack up a tad and go to item 3.
3. Remove "C" Frame Bolts and remove "C" Frame. Have in hand ZF Doc "C" Frame Plates for the re-installation of "C" Frame Later.
4. After "C" frame is removed, Lower engine (jack under oil pan) a few inches.
5. Remove universal joint on drive shaft to rear by differential. Mark drive shaft so you get it installed for possible correct balance later. Pull drive shaft from transmission. Beware of transmission fluid leaking all over once drive shaft is removed from transmission.
6. I would drain transmission fluid before I start this job and replace with new
Castrol TWS 10W-60 later after reinstallation of transmission. Get yourself a 17 mm Allen Wrench also for transmission plugs.
Castrol TWS 10W-60 I just buy
Castrol TWS 10W-60 as well as
Amsoil 10W-40 (Engine) online. Transmission ZF S6-40 takes 4.4 pints or 2.1 Liters of
Castrol TWS 10W-60.
7. On top side remove shifter knob, and shifter boot so you can lower transmission later with shifter attached. The lower you can get the rear of the engine the better but make sure your cam covers do not hit brake booster of fire wall as you lower rear of engine a bit.
8. Remove clutch slave cylinder and leave it hang.
9. Remove transmission bolts (jack under oil pan and with another jack under transmission (the best is transmission jack), use BIG flat head screw driver between transmission and bell housing as it takes some pressure as you jack up and down a bit to free the transmission from the pilot bearing. There are some electrical connections on transmission you remove before pulling the transmission free.
10. Remove bell housing bolts. Pull Bell housing off but watch the throw out bearing as it stays with the pressure plate. The black label and blue label transmissons take different throw out bearings.
11. Remove pressure plate bolts being carefull to loosen bolts equally all around the pressure plate a step at a time. Do not just remove one bolt at a time. Remove pressure plate (it will fall off once all bolts are removed. The clutch plate will also fall off.
12. You might want to now inspect the pressure plate surface and surface of the flywheel.
13. You also want to remove the pilot bearing (there are pilot bearing pullers if it will not come out with flat screw driver wedging it out). I would have a new pilot bearing/bushing on hand.
