RE: Cleaning motors in service
1.Stop the motor
2.Cut off the power
3.Log Out and Tag out
4.Verify the motor don´t start open the connection box and look for damage on leads and power wires.
5.Take an insulation reading(IR) at 500 V from the CCM and record the reading.
6.Uncouple the motor
7.Made a complete visual motor´s inspection looking for damage in motor parts,couplings or pulley, belts and foundations and for unusual services conditions.
8.Clean all motor´s surface with a dry wype
9.Apply new grease to the bearings.Take out the fun and fun cover.
10.Clean the grase excess
11.wash and clean the fun (If is made with plastic)
12.Clean the cover inside
13 Assembly the fun and cover fun.
14.Couple and align the motor
15.Restore the power conditions and start the motor.
16.Take a voltages, Line Current and frame and bearings temperature readings,and vibration levels.
Remember record all readings.
If you don´t have a good IR readings the motor could be sended to shop or could be dry out on site with a blower, the motor may need dissambled.

Note: fun => fan
I would suggest #16 => #1.
That is, measure those values before the motor cools and is otherwise touched.

However one person's "IN service" I could easily see as another person's "LEFT installed".
Because to me, doing anything to a mangler while it is in motion can't be what any sane person would be asking..?
"I'll just reach in here while its off and clean it with this towel" CLACK!

RE: Cleaning motors in service
General solvents we had available for removing spent flux were Chlorothene (trichloroethane) and Triklone (trichloroethylene). There was an unofficial stash of other things like Genklene (no idea), Arklone (don't know that one either), and Methoklone (Dichloromethane) for those jobs where things weren't going too well with conventional solvents. Maintenance used to get the spent solvent from the line when it was too dirty to use in production - we would use it for initial degreasing of machine parts, then move on to fresh solvent.
Some of the oldtimers had some nasty skin problems and, as waross says, 'nervous system problems'. I'm sure carbon tet was used there, but before my time.
The names are the old ICI brand names.

RE: Cleaning motors in service
1- safety of personel
2- "do no harm"
- don't put contaminants into machinery by use of pressurized fluids
- use care in selecting any solvents
Of course since every choice has some undesirable aspects, be certain that the grand sum of undesireable factors and risks are within an absolutely acceptable range.
Please let us all know how this works out for you! and don't forget FAQ731-376
RE: Cleaning motors in service
Thanks for the corrections and suggestion, Yes is better start with the Item 16. The New The list is:
0.With the motor running, Take a voltages, Line Current, frame and bearings temperature readings,and vibration levels.
1.Stop the motor
2.Cut off the power
3.Log Out and Tag out
4.Verify the motor don´t start.Open the connection box and look for damage on leads and power wires.
5.Take an insulation reading(IR) at 500 V from the CCM and record the reading.
6.Uncouple the motor
7.Made a complete visual motor´s inspection looking for damage in motor parts,couplings or pulley, belts and foundations and for unusual services conditions.
8.Clean all motor´s surface with a dry wype.
9.Apply new grease to the bearings.Take out the fan and fan cover.
10.Clean the grase excess
11.Wash and clean the fan (If is made with plastic)
12.Clean the fan cover inside
13 Assembly the fan and cover fan.
14.Couple and align the motor
15.Restore the power conditions and start the motor.
16.Take a voltages, Line Current and frame and bearings temperature readings,and vibration levels and compare with readings taked in the item 0.
Remember record all readings.
If you don´t have a good IR readings the motor could be sended to shop or could be dry out on site with a blower, the motor may need dissambled.
