Which lubricants I need to use for a gear motor?
Motor Vehicle Maintenance & Repair Asked on December 1, 2020
I just dismount a micro motor for the electric windows.
I need to lubricate it.
Which is the best way to lubricate the gears? I saw that there is plastic outside. I will not use the MoS2 grease.
EDIT
I don’t have the picture available but I found a similar one gearbox dismounted.
One Answer
This is a difficult question as many greases affect plastics. A silicone grease, most likely to be compatible with plastics, won't provide enough lubrication for the metal gears. In your case I'd try to source some ptfe grease, specified for metal/plastic applications.
It is important to disassemble the gear and painstakingly clean the gear from debris or old grease. Also avoid brake cleaner on the plastic parts..
