Today I went to Pick your Part in Santa Fe Springs for my practice session with the following agenda:

• take apart a/c condenser fan
• purchase trailing shoes for rear drum brakes (and practice R&R if possible)
• remove starter and take it apart
• Inspect wiper linkage

The new client

As you see from the picture, the car had special spike wheel nuts.
So I decided to pop the hub nut cover, undo the rear spindle nut (32mm) and take the wheel , drum and nub as one part


Destroyed nut cap (screwdriver and hammer)



I was able to slide entire assembly off the spindle



Time to take apart the brake system

I tried few removal methods and tools and still need to revise some stuff
Let's do the fan



The blade is attached to the hub with Phillips-flat screws; I used my universal screwdriver



Motor on the shroud (it's spot welded in 3 places)



Back side


Motor is open; its armature looks like HD drive

The brushes are touching flat commutator from the back; the motor uses ring graphite magnet attached to the back cover
In my opinion the motor fails to spin because the shielded bearing in the hub is getting contaminated so in theory the motor could be rebuild after spot welds are carefully drilled out and bearings are replaced as necessary
