P.D.I. brush and drift clutch
The resistance unit, stabilized brush, sight-stem bushing and drift-clutch arrangement shown together in the manual cutaway.
Follow the mechanism
Relative motion between the stabilized brush and resistance unit supplies the direction indication.
The drift clutch and hub surround the sight stem. The illustrated leads run to remote connections; they are not plugs mounted on this frame.
Geometry follows the cited drawings and photographs. Unmeasured dimensions remain approximate; exploded spacing reveals existing model groups rather than a prescribed disassembly procedure.
