How to Flush Gearboxes and Bearing Housings

[FONT=Verdana, Arial, Helvetica, sans-serif]Gearboxes and bearing housings periodically need a thorough flushing rather than a simple drain and fill. Several signs point to this requirement, such as overheating of the sump, gross liquid or solid contamination, and development of a severe wear pattern. Material evidence in the form of sludge, rust, moisture, wear metals, gel or other viscous residue that is present at the beginning of the drain should confirm to the technician that a flush is in order. A thorough flush is also useful for removing construction and assembly contaminants from equipment sumps prior to commissioning.

Ok, I'm confused on posting etiquette:

Article is in a publication - why it is here

Important for maintenance forums - ZVW30, NHW20 and the 'Gen 1' forums ... but replication seems overkill

I look forward to learning how best to handle something like this.
