Joint first post. This machine is 21 years old. It has a metal sheet floor riveted in place with large rivets. The motor, which appears to be a Siemens model, requiring standard brushes, has 6 polyamide thick self locking ties holding the loom to the motor. The two rear 13 mm head mounting bolts are fitted such that the head of one faces the inside of the machine, limiting accessibility.
Should I lie the machine on its rear, such that no weight is borne by the drum, and attempt to change the brushes in situ, working around the pump, and drum dampers, or is there a better way?
The potential problem with motor removal is its successful replacement.

All easily accessible just with the back off. Cut off the cable ties (replace those on completion) and undo both bolts. A 13mm ring spanner ideal and a little gentle persuasion with a hammer helps release the one facing inside. Once motor released be sure to clean away ALL traces of carbon dust from within. Complete strip down of motor preferred (mark carefully the stator position before you do) 😉

Thank you for those helpful comments.I shall proceed as you advise.

Removed motor today. Only 2 wire ties. I mis-counted. I have 2 further, hopefully, final, questions.
Would you clean the stator with a paint brush, or a can of compressed air?
Secondly, this world seems to be one without thread compounds or quoted torque settings. I had to use a socket arm to release the motor bolts. I note the angle of the bolt thread pitch, and the large bolt head flange. They were torqued to circa 120 Newton.metres. Washing machines rotate, and vibrate from uneven loads. Are they held together by all fasteners being tightened according to the strength of the operator, in other words, as tight as possible?

1) Compressed air
2) Hand tight, not necessary to use torque wrench.
