Product Description
Webb 65151B 16.5 x 5 Balanced Front Brake Drum – 123589 / 3598X
The Webb 65151B is a 16.5 x 5-inch balanced cast-iron front brake drum designed for steer-axle use. It has an outboard mounting configuration with an 8.78-inch pilot, 11.25-inch bolt circle, and 10 mounting holes measuring 1.31 inches in diameter.
Webb identifies Meritor 123589, ConMet 107453, and Gunite 3598X and 3758X as interchanges for the 65151B. Its dimensions are very close to several other Webb 16.5 x 5 front drums, so the pilot diameter, mounting-hole size, and overall depth are particularly useful when confirming the correct drum.
