1970 RUG AZ speedometer drive tooth number
« on: November 06, 2019, 02:04:27 pm »
Hi all Ive pulled the gearbox to freshen up after 50+ years and realised the speed gear needs replacing as well.  Our car is standard 3.91, rug az close ratio top loader etc.  I read I need a type 1 gear but no idea of teeth number.  Can anyone assist please cause Im a bit lost. Many thanks Craig Mac

Thankyou Jeff brilliant. Excellent formulas. 16 driven gear and 7 drive gear due to the reducer gearbox. Many thanks Craig
