The design of the automatic transmission drive disk is shown in Figure 5.9.
with motor «N62», as standard, an automatic transmission with a drive disc is used. The drive disk, and the automatic transmission torque converter connected to it, serves as a flywheel for the engine.
The drive disk is attached to the crankshaft flange with nine bolts (3). After removing the drive disk, replace the fastening bolts with new ones, with a preliminary application of a locking compound to their threaded part. Due to the presence of a centering sleeve (2), the drive disc can only be installed in one position. Before pressing on the drive disk of the ring gear, it is heated to a temperature of 220-250°C. The installation of the ring gear on the drive disk should be carried out in repair shops at the service station.
bolts (M12x1.5x28) screw the fasteners of the drive disk crosswise, with a torque of 120 Nm (12.0 kgf·m).
The automatic transmission torque converter is attached to the drive disk with four M10x17.5 bolts (4).
Permissible runout of the drive disk, when measured along the outer circumference, is no more than 0.20 mm.
The dual-mass flywheel mounted on a power unit equipped with a manual transmission is similar in design to the flywheel used with engines of models «M54», M62» And «M57».
