CAUTION:Only install the timing belt when the engine has cooled down. The engine must have been switched off for at least four hours. NOTE:Position of the flattened area on the special tool. Check the alignment of the front plate. If necessary, center the front plate. - Front plate
- Crankshaft
- Special Tool
| | -
CAUTION:Carry out Step 3 immediately after Step 2 to prevent the oil seal from contracting. Only remove the support ring immediately prior to installation of the oil seal. NOTE:Position of the flattened area on the special tool. NOTE:The support ring must not yet be removed from the oil seal. NOTE:Fit the oil seal dry. Fit the oil seal, together with the bolt of the crankshaft front timing pulley flange. - Remove the special tool and the support ring.
