TR250 Wiper motor

[Don Malling <dmallin@attglobal.net>]

I have a working wiper motor and gear assembly for my TR250, but the hammerite 
motor cover is rusty. 
I would like to take it apart bead blast it and paint it.

Are these things easy to put back together? I've checked Dan Masters and he 
doesn't say much about 
disassembly and reassembly so I assume it's straight forward.

Also does anyone know if the Spitfire and TR2 TR3 TR4A use the same wiper motor 
as the TR250. They 
look the same, but have different part numbers at Moss. Moss does not list the 
TR250 part number. 
Reason I ask is that I thought I might buy one on eBay and practice on it 
before I try my "good" 
TR250 motor.

Thanks,
