Hub dynamo pulley 25/30HP DIN

Este
dynamo pulley hub is for the 25 and early 30 Din Hp engines (36 Hp SAE).These hubs
are usually worn out due to the construction, but mainly due to the wrong
tightening of the large dynamo pulley nut. All 25Hp
engines use 3-piece pulleys with this separate hub and 2 separate pulley halves
for the wide belt (BBT 1941-050)

All 30DinHp
(36SAE) engines use this hub with different pulley halves until engine no
1-120614 (-07/55) for a narrow belt (BBT 1941).

Stop your
search for a good USED or NOS hub now, BBT has had these made from a NOS
specimen to exact dimensions and available new from now on.
