paintman Posted January 19, 2009 Share Posted January 19, 2009 Follow the sequence in the manual. If you haven't got one then http://www.green-oval.com The TC should stay on the gearbox throughout the operations. No need to remove it. It is surprisingly heavy & unless the box & TC are new it will have alot of gearbox fluid in it even if you have drained the gearbox. You cannot drain it without removing it. Once you remove the 4 bolts that hold the flex plate to the TC the TC is not connected to the engine so unless the box is tipped downwards it shouldn't slide forward. You might want to put something across it to stop any chance of it doing so. These bolts are accessed by removing the cover plate at the bottom front of the bellhousing. You will need to turn the engine to get at them one at a time as they are at 90deg to each other. When refitting the engine check that the distance from a straight edge laid across the mouth of the gearbox bellhousing to the front of any of the 4 bosses (the threaded lumps that the flex plate is bolted to) on the TC is 50mm. That shows the TC is correctly engaged with the box pump. A couple of lengths of threaded rod screwed into a couple of the bellhousing bolt holes in the rear of the engine will help to line the box & engine up when refitting engine to box (or box to engine). Makes lining up a manual box after a clutch change dead easy. Also reduces the risk of a slip leaving the gearbox hanging on the input shaft. After the two units are pushed together & a couple of the ordinary bolts are in just renmove the threaded roda & fit the bolts. Quote Link to comment Share on other sites More sharing options...
steve_d Posted January 19, 2009 Share Posted January 19, 2009 As Paintman said but when you have unbolted the TC get a lever or big screwdriver and lever the TC back away from the drive plate. There is a spigot in the front of the TC that engages in the end of the crank but it can rust and jam in. If you don't free it first it will pull the TC with it when you take the engine out. It only engages about 10-15mm. It is also a good idea to mark the TC and drive plate so that they go back in the same place or you may have balance issues. I just use a spray paint.
