TECO Electric Motor AEHH8PCF

Refer to Table 1 for applicable interval in hours for your specific bearing number and RPM

Is the motor used in belt drive, dirty, high ambient temperature, or high humidity environments?

Select the type of grease used for the motor

Is there a lubrication nameplate attached to the motor?

Ensure identical grease or its equivalents are used when maintaining lubrication schedule

Ensure different kinds of grease are not mixed

SECTION: 2.4 Insulation resistance test during storage

Even during storage, the insulation resistance should be kept above the specified values

Insulation resistance test should be performed once every three months

SECTION: 4.1.2 Measurement of insulation resistance

WARNING — During and immediately after measuring, the terminals must not be touched as they may carry residual dangerous voltages:

Furthermore, if power cables are connected, make sure that the power supplies are clearly disconnected and there are no moving parts

For rated voltage below 1000V, measured with a 500 VDC megger

For rated voltage above 1000V, measured with a 1000VDC megger

In accordance with IEEE 43, clause 9.3, the following formula should be applied: R~ (Rated voltage (v) / 1000 + 1) x 10 (MΩ)

Ensure the volume and quality of lubrication oil are in compliance with specifications

Check motion of the oil ring to ensure it is not clamped

Measure the shaft endplay and ensure it is within the specified range of the red groove of the shaft

Is the shaft endplay within the ±0.118 in. (±3mm) range of the drive-end shaft shoulder?

Bearing Protection — Tilt-Pad Bearings

Rotate the shaft a few revolutions

Pour in approximately one cup of oil

Clean the interior of the bearing housing and flush with clean oil or kerosene

Wipe the bearing halves and shaft journal with a lint-free cloth soaked in clean oil

Inspect all parts for imperfections

Remove imperfections using appropriate methods such as stoning, scraping, or filing, followed by thorough cleaning

Is the floating labyrinth seal free of cracks or chips?

Ensure the bottom half seal's drilled holes are positioned at the bottom toward the inside of the bearing

Apply a bead of Curil-T around the seal half O.D.'s on both sides adjacent to the garter spring groove

Place the bottom seal half on top of the shaft and roll it into position
