Hi Doc,
I don't have a CRD, but maybe I can help out a little. If you post your question in the 'CRD - love that torque!' section, you'll probably get better answers because CRD owners will be looking there. I have read enough about CRDs to remember that the timing belt should be changed about every 100,000 miles, so that will be important to do ASAP. If it breaks or slips, the consequences for your engine can be expensive. I don't know about the harmonic balancer-- that must be a CRD thing. Anyway, good luck!
