Not so much a question as some tips
Kent once again has takin the guess work out installing new brushes.
This is a back bender!
If you're real careful, you don't need to remove the underdash cover(fabric)
Loosen the screws and carefully pull towards the rear of the car.
won't move much, but enough to able to pull the plastic cover away from the "waffle" motor/fan cover.
{Left it in because I couldn't figure out how to yank the cover which is fastened with staples to the duct}
Remember: IF YOU FORCE THINGS THEY WILL BREAK!!!!!
As Kent says "take your time"
Well
Took the housing out and used this stuff called "Tuff Stuff" (spray foam cleaner)and cue tips and carefully rinsed the cage with water. DO NOTE SOAK MOTOR.
Sprayed the armature and such with contact cleaner

I've become the proud owner of an 1986 300sdl turbo!
and have begun doing my part to advance Kent's great place here.
The motor has 151000 miles and appears in good shape(little or no smoke/pickup/etc)
I've ordered new injectors in my excitement and other stuff before realizing that Purging is a good preventative maintence.(Came from a gas home)
will purging before installing the new injectors be of benefit?
Thanks in advance!
And so begins a new romance.....
