simonb Posted September 4, 2006 Share Posted September 4, 2006 You need to count the pinion teeth as well to work out the ratio.... Quote Link to comment Share on other sites More sharing options...
rtbarton Posted September 4, 2006 Share Posted September 4, 2006 Divide the number of teeth on the crownwheel by the number of teeth on the pinion. Accordign to my notes Rover Pinions have 10 teeth, apart from the 3.54:1 which has 13 So 4.7:1 47 Teeth on crownwheel Std LR & Rover 75 (from the '50's) 4.3:1 43 Rover 90 (may be different if overdrive fitted to car) 3.9:1 39 Rover 3 litre (do) 3.5:1 46 Rover 3.5 litre (do) Range Rover Classic Quote Link to comment Share on other sites More sharing options...
