Pontiac 14088765 Engine Crankshaft Flywheel

Since it's a manual transmission, you'll have to unbolt the clutch housing and clutch before you can take out the transmission, only then can the flywheel be unbolted from the crankshaft rear flange. To temporarily lock the crankshaft and thus make the work of loosening bolts easier a piece of wood can be inserted between one of the crankshaft throws and the side of the engine block or an alignment tool can be inserted through the flywheel and pushed up against the block. It is recommended that the surfaces to be mated of the flywheel and the crankshaft be cleaned before proceeding to install the flywheel. For the manual transmission type, the flywheel must be to have the dowel hole in the crankshaft matching a dowel hole in the flywheel, for the automatic transmission type, the flywheel has to be installed in a manner that the torque converter attaching pads face the transmission. Tightening of bolts should be done gradually and up to the recommended torque value and where practical it is advisable to use a thread sealant on the bolts. In the same manner, an arrangement of a block of wood or a center punch tool may be placed against the block, so as to prevent the flywheel from rotating during the tightening process.
