Prith Posted December 18, 2008 Share Posted December 18, 2008 Hi! Guys, am looking for a used 1968 Series 2A LWB overdrive for the diesel engine. Does any one want to part with a good condition one. Or can anyone inform me where I can get 2nd hand ones or new ones? Rgds Prith Quote Link to comment Share on other sites More sharing options...

Gazzar Posted December 21, 2008 Share Posted December 21, 2008 Note: All most any series overdrive will work, I think only the 1 tonne varient was different. There is also the rocky mountain roverdrive, if you are rich. G. Quote Link to comment Share on other sites More sharing options...

Ashcroft also used to do a set of transfer box gears that provided a different high-ratio. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted December 21, 2008 Share Posted December 21, 2008 Swapping diffs is maybe not such a good option - the 2.25 Diesel may not have enough power to pull the higher ratio all the time, especially when loaded, and if the back axle is Salisbury the swap is that much harder to do.

Prith Posted December 21, 2008 Author Share Posted December 21, 2008 Thanks guys. Wish I could find a cheaper one. Too expensive. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted December 21, 2008 Share Posted December 21, 2008 Fitting slightly larger diameter tyres can help, it's another option. Quote Link to comment Share on other sites More sharing options...

task Posted December 21, 2008 Share Posted December 21, 2008 What do you mean by later axle? 10 spline Range Rover / Defender / Discovery. I used to run a pair from a 90 in my SWB series but that was a Essex V6. Planning on fitting a pair to the SIII I'm building at the moment too, I have a Range Rover I'm breaking up for parts. Although, as FridgeFreezer mentioned, possibly not such a plan with the old 2.25 Diesel engine. I also forgot that a Series LWB may well have a salisbury rear axle.

Snagger Posted December 22, 2008 Share Posted December 22, 2008 Remember to get the speedo recallibrated if you change the diffs or tyre diameter, or you'll be going much faster than you think. The HRTC and overdrive don't affect speedo callibration. Quote Link to comment Share on other sites More sharing options...
Mark Posted December 22, 2008 Share Posted December 22, 2008 Just, as a note, I have a 2.25 diesel 1968 LWB Series 2a and the overdrive is definitely the way to go. The diffs would be too tall for the lower gears, and the high ratio transfer box kit was designed for use behind a v8, so again too tall for a 2.25. A LWB will be running 7.50's anyway, so whilst taller tyres are an option you would need to be looking at 255/85's or the like. Just speaking from experience, but the overdrive is the right choice. Just a question of hunting round to pick one up. As has been said, pretty much any fairey overdrive will fit. hth Mark Quote Link to comment Share on other sites More sharing options...
