Dismantling Height for Piston
H1 : For dismantling of piston and connecting rod at the camshaft side.
H2 : For dismantling of piston and connecting rod passing the alternator. (Remaining cover not removed).
H3 : For dismantling of piston and connecting rod passing the turbocharger.
If lower dismantling height is required, special tools can be delivered. See also B 10 01 1, Low Dismantling Height.
