A stiffer turbocharger support was developed for new engines after
vibration had caused problems in the supports of one of the
turbochargers of the first 10RTA96C engine. Excessive transverse
movement of the exhaust manifolds on the first such models was also
recorded. This was remedied by stiffening the manifold support in
the transverse direction, thus halving the manifold movements. Excessive
movements of the manifolds also led to the breakage of cooling water
discharge pipes; the adoption of flexible pipes of a proprietary make
as standard solved the problem
