Talkwrench Posted August 28, 2014 Share Posted August 28, 2014 Guys whats the biggest tyre you can stuff under a Herald without modifying the guards? Ive got 175x70x13's on 6" mags however I would really like to get the tallest rear tyres I can get on those 13" rims .. My gearing is terrible with the bigger motor its not even worth me using 1st gear , revs up far too quick.. Quote Link to comment Share on other sites More sharing options...
andy thompson Posted August 28, 2014 Share Posted August 28, 2014 You need a 3.27 diff + possibly different driveshaft flanges - Ask David Markich 9271 4834 if he has one - they were fitted to automatic dolomite 1850 so relatively common.

Nick Jones Posted August 28, 2014 Share Posted August 28, 2014 Failing the 3.27 diff a 3.63 diff (Spit 1500, dolly 1500 auto, TR7 4 speed). If you are still on the Herald 4.11 diff anything else will be an improvement!Nick Quote Link to comment Share on other sites More sharing options...
andy thompson Posted August 28, 2014 Share Posted August 28, 2014 Only 1850 dollys in oz - most TR7 are 5 speed - never seen a 4 speed here? Quote Link to comment Share on other sites More sharing options...
Paudman Posted August 28, 2014 Share Posted August 28, 2014 You can get a tractor tyre under one; gets it right off the ground for changing wheels etc. Quote Link to comment Share on other sites More sharing options...
Talkwrench Posted August 29, 2014 Author Share Posted August 29, 2014 I believe its a vitesse diff in there , I think the ratio by my workings out is roughly 3.7, did they have something like that? IS the diff hard to change? Quote Link to comment Share on other sites More sharing options...
andy thompson Posted August 29, 2014 Share Posted August 29, 2014 Vitesse diff is 3.89 Spit (1500) diff is 3.63 - rareish in Oz?3.27 is best for cruising in any 2.5 small chassis - they can be weak if abused- but so can any small chassis diffDiff change is a bit fiddly but perfectly possible Quote Link to comment Share on other sites More sharing options...

IS the diff hard to change? Just done mine and had a 2" exhaust in the way. They're not light at all and that's the major issue. Getting them out is easy and use a trolley jack with a wide piece of wood on it to stabilise it. also, the higher the car the easier it'll be. Getting it back can be a faff. Especially if you've replaced the rear bushes. Quote Link to comment Share on other sites More sharing options...
Talkwrench Posted August 30, 2014 Author Share Posted August 30, 2014 Kind of why I was thinking of getting a bigger tyre in there and saving all the expense and hassle .. Quote Link to comment Share on other sites More sharing options...
