  Q: How does the Flywheel factor into the removal and reinstallation of a transmission on Mazda MX-5 Miata?

  A:

  In order to eliminate the transmission, raise the vehicle and put it on jackstands, then remove the transmission. In models with a manual transmission, disconnect the clutch disc and the cover of the clutch and it may be recommended to check or replace the clutch components and pilot bearing. Draw alignment marks on flywheel/driveplate and engine rear plate so that they are re-installed correctly in future. Unscrew the bolts that have the flywheel/driveplate attached to the crankshaft, poking the flywheel with a screwdriver in case the crankshaft rotates. Never turn the crankshaft with the flywheel/ driveplate removed to ensure the alignment is not lost, so, when this is required, punch alignment marks on both flywheel and crankshaft before removing. Installation Removal of flywheel/driveplate, driveplate backing plate and adapter (Automatic transmission models) taking note of the orientation of plates. Clean flywheel to eliminate grease and oil, look for cracks, grooves, places of burning and score marks on it, and deal with light scoring with emery cloth. Inspect broken teeth on ring gear and inspect warpage with straightedge and have machined in machine shop. Wipe the mating surfaces of the flywheel/driveplate and crankshaft with oil and inspect them, remove the crankshaft rear seal when it is leaking and replace it before installing again. To install it, take any thread sealant out of the holes of the crankshaft flywheel bolts and bolts, and replace the bolts that can not be completely cleaned. Install the flywheel or adapter, driveplate and backing plate to the crankshaft as the marks made during removal. Use thread sealant on threads of used bolts, but not on new bolts. When tightening the bolts apply the screwdriver to ensure the flywheel/driveplate does not rotate, in a criss-cross pattern, working to the final torque in three or four steps. The rest of the sequence is the opposite, in terms of removal.
