not at all , the diesel belts have a hard life and the lower the rpm the higher the loads .
The diesel crankshaft at low rpm turns in a series of uneven jerks with each power stoke so the cambelt is constantly tugged ... that's why they have a crank pulley vibration damper on the end of the crankshaft to minimise these tugs ..
