Before finally installing it back, there should be a line drawn from the driveplate to the extremity of the crankshaft as a guide. Third, undo all the bolts holding the driveplate to the crankshaft rear flange while if the crankshaft turning, insert the flat edge of a screwdriver between the driveplate and crankshaft making it impossible for the driveplate to turn. Next, remove the driveplate on board and remember place and position of spacer rings if any were used. Of course, one should wear gloves or cover hands, as teeth on the ring gear are rather sharp. Remove any grease or oil from the driveplate and inspect the starter ring gear teeth for cracks of breaks and place the driveplate on a flat surface to inspect it for warping. Before installing the driveplate to the crankshaft, remove all debris on the mating surfaces of driveplate and crankshaft through cleaning them before placing the driveplate in contact (with) the crankshaft to fit the two marked positions. Use a non hardening thread locking compound to the bolt threads before fitting. There must be an anticlockwise torque of about 110 lb. ft. While tightening the bolts you must ensure that the crankshaft cannot turn by using a screwdriver and after tightening bolts to the specified torque you can tighten them again in two or three steps in a criss-cross fashion. Last but not the least, restore the system to normalcy by using the steps that are involved in the removal process in the reverse method.
