Drycleaning solvent P-D-680 is toxic and flammable. Wear protective goggles and gloves and use only
in a well-ventilated area. Avoid contact with skin, eyes, and clothes and don't breathe vapors. Do not
use near open flame or excessive heat. The flash point is 100-138°F (38-59°C). If you become dizzy,

37. Use a feeler gage and check axle bearing clearance and wear. Radial clearance between axle and bearings is
0.010 inch (0.25 mm). Check that 0.014 inch (0.36 mm) shims are in place between axle cap and traction motor
