Removal
1. Remove the front covers of both regulators. 2. Set the piston of the first cylinder to the position 45° before TDC.
3. Lock the camshafts using the rods (1).
4. Mark the position of the timing chain relative to the camshaft sprockets.
5. Remove the timing chain tensioner.
6. Remove the upper guide arms. Remove only the right arm for the right adjuster.
7. Remove the right exhaust camshaft sprocket. 8. Unscrew the bolt (3) securing the fittings (4).
9. Unscrew the nut (6), remove the cover (12), the left camshaft sprocket (13) with the adjusting piston (14) and the conical spring (14a). Unscrew the bolts (15) and remove the flange from the inlet camshaft.
Installation
1. Screw the flange (16) onto the intake camshaft (22). Make sure the guide pins (21) are installed correctly. Replace the bolts (15).
2. Insert the spherical spring (14a) and install the adjusting piston (14) on the flange (16) in a fixed position (blocking tooth B).
3. Set the intake camshaft sprocket to the fixed position (blocking tooth B) on the splines of the adjusting piston (14); lift the timing chain upward to perform this procedure.
4. Loosen the stop nut. Hold the regulator assembly for this operation.
5. Install the cover (12).
6. Tighten the nut (6). Hold the camshaft (22) with the wrench (03).
7. Install the fittings (4) in a fixed position.
