Einar Posted June 26, 2014 Share Posted June 26, 2014 I’m about to change the steering rack for my Vitesse - LHD. The rack is original from Vitesse 6 which is 6 tooth pinion – fitted to Herald and Vitesse 6. However, there is a 2l engine fitted in the car and I would like to go for the correct one which is 7 tooth pinion – fitted to Mk1 and Mk2, see http://vitesse.no/Projects/Winter-2008-2009/TheCourier289-SteeringRack.pdf . Rimmer list 305931 and 305931HR, where HR is High Ratio. Does anyone know whether HR is the same as 7 tooth pinion (Rimmer didn’t know!!), meaning that I should order 305931HR for having the 7 tooth pinion to fit the heavier 2l engine…… Quote Link to comment Share on other sites More sharing options...
andy thompson Posted June 26, 2014 Share Posted June 26, 2014 http://www.tsoaq.org.au/index.php/triumph-info/technical-information/22-steering-racksI thought that GT6 and Vitesse + 2000 saloon etc had 6 tooth pinions (slow rack) whereas Spit, most Heralds and TR's had 7 tooth pinion "quicker" rack.Anyway a TR6 LHD pinion will sort you - I have access to loads of them if you are desperate - my local Triumph garage converted about 100 TR's from LHD to RHD http://www.rimmerbros.co.uk/Item--i-134688 This will give the "stanpart" higher ratio Quote Link to comment Share on other sites More sharing options...
Encom Posted June 27, 2014 Share Posted June 27, 2014 I asked Rimmers the same question, and was told they are the same ratio! I found new 7 tooth ones from Jagsaw from memory for 98 quid. Quote Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 27, 2014 Share Posted June 27, 2014 slow rack has a small identification groove turned in the input shaft splines to identify it we had an exchange rack before we did any homework , all the same they say... but with a 7 tooth and my old biceps needed 4 shreaded wheat to park the ground anchor weight, then you find out the basics and get the correct one , even went back to the orig weston steering wheel diameter to keep the handwheel loads down its all down to preferencePete Quote Link to comment Share on other sites More sharing options...
