I know that the 642 seems to not be very forgiving when ever something steps out of line....just briefly. They like plenty of Preventative Maintenance.

So get this though--all the sheave pulleys and the water pump it self on my OM648 failed around 100K miles. the pulleys went first and about 2 months later the pump started leaking. this 642 is way past that mileage and neither of the bearings in the sheaves or the tensioner show any signs of wear and the pump is still snug and dry as new. . .
