Blue River Handpiece Repair

In the handpiece (dental drill) world of dentistry...cleanliness is next to godliness.
They go in your mouth and drill holes, cut fissures, draw pulp in root canals and can make gaping holes for implants.
So, yeah cleanliness, inside and out.
Below...ugh, wtf and whoa, what did they l**e this with?

Midwest RDH in horrible shape. End plates worn, rotor housing scored. Bearings black with sludge. Debris in the gearing. One of the foulest smelling pos i have seen in a long time. Vanes worn so thin they are about to snap in two.
Life expectancy...nil. Retiring. Un-economical to repair.
