Removal and installation the chain drive of the control mechanism
The gearbox is removed. Remove the driven disk. Remove the timing chain protective covers. Remove the camshaft drive chains. Remove the auxiliary chain. drives. For protection against cuts, wrap the cutting edges of the 3.3 mm diameter drill with insulating tape. Press the chain tensioner rail in the "direction of the arrow" and lock the chain tensioner with the 3.3 mm diameter drill "pos. 4". Risk of malfunction due to reverse travel of the already used camshaft drive chain. For reassembly, mark the direction of the drive chain with an arrow, using paint for this. Unscrew bolts "2" and "3" and remove the chain sprockets together with the chain and tensioner bar "1".
Install
Installation in reverse order. Crankshaft "1" is locked in the TDC position using locking bolt "3242". First, install sprocket "2" of the left camshaft drive chain. Install tensioner bar "1" with the drive chain mounted. Install the right camshaft chain sprocket "3". Press the chain guide bar in the direction of the arrow and remove the drill bit "4" from the chain tensioner. Install the auxiliary chain. drives. Install the timing chain protective covers.
