7.1 Inspection of the PT Meter
Clean and inspect all parts for damage and wear. Replace parts as required. Clean bearings,
journals and thrust washers with solvents and paper towels. Assemble dry. Do not spray
lubricants as either a cleaner or a lubricant.
Upstream and downstream cones should have sharp edges free of nicks. Thrust washers
should be seated flat in cone recesses.
Rotor hub and blade edges should be sharp and free of nicks and debris. Rotor blades
should not be twisted or bent.
The bearing, which is pressed into the rotor hub, should have an equal amount protruding
from both hub faces. The bearing internal surface and journal external surface should be
smooth and free of scratches, wear spots, chips, and nicks. The bearing and journal are a
matched set. For replacement, return the rotor to Daniel Measurement and Control, Inc. It
is not recommended that the bearing be replaced in the field.
