Hello John,

You wrote on the Ferguson Forum:
For your information to help you calculate the pulley size....90,000 engine revolutions = 1 engine hour.
do you agree with this calculation?
90 000 engine revolution in one hour > 1500 engine revolutions per minute
engine révolutions or crankshaft revolutions it's the same is'n it !!
For you, these 90000 engine revolutions per hour is an average ? or 1500 revolutions per minute?
if we accept this value:
The pulley size for the tachometer must be the same than the pulley from the crankshaft?!
diameter # 12 cm.
