chrisstevenson Posted August 23, 2005 Share Posted August 23, 2005 When crusing at 70mph the engine revs on our 2.0XDi are abour 3300rpm when in 5th gear, this is about 500 - 700prm higher then a variety of other landrovers/other cars I've recently driven and the only reason I mention it is because of the noise - and the fact that the engine sounds like its working too hard. The Freelander is a 1999 model, do later gearboxes have a different 5th gear ratio better matched to the engine? Quote Link to comment Share on other sites More sharing options...
jules Posted August 23, 2005 Share Posted August 23, 2005 Yes but the gear box from the td4 will not fit nor will the 1.8. and the v6 is a hole load not worth bothering. heve you unpluged the initions valve it makes the engin labour less.

chrisstevenson Posted August 23, 2005 Author Share Posted August 23, 2005 Hi, Thanks, but what and where is the initions valve? Chris Quote Link to comment Share on other sites More sharing options...
jules Posted August 23, 2005 Share Posted August 23, 2005 Sorry I can't spell Imitions Bulk head next to you fuel pump reset is a funny shaped thing with two fuel lines and two plugs. I have forgoten which one it is and I've sold the car so mmm bugger which one Pass I will get back to you Quote Link to comment Share on other sites More sharing options...
chrisstevenson Posted August 23, 2005 Author Share Posted August 23, 2005 ok thanks, I'll take a photo and post it on here later. What does it do, this gizmo thing? Quote Link to comment Share on other sites More sharing options...
MarkieB Posted August 23, 2005 Share Posted August 23, 2005 An Emissions valve would possibly increase revs to control Emissions, making a diesel less smokey? Quote Link to comment Share on other sites More sharing options...
DEANO3528 Posted August 24, 2005 Share Posted August 24, 2005 Description sounds possibly like an EGR valve? Quote Link to comment Share on other sites More sharing options...
garrycol Posted August 24, 2005 Share Posted August 24, 2005 If you have the inclination replace the IRD with one from TD4 - this will reduce revs to about 2700 at 110kph. The down side is that all gears including first will be slightly higher but this is not a problem in most situations - the upside is that fuel economy improves by about 10%. I have made this change to my 98 XEDI and it works well. Garry Quote Link to comment Share on other sites More sharing options...
jules Posted August 25, 2005 Share Posted August 25, 2005 There is only one IRD on the market there all the same the older one led to the tyre problems that gave the freelader such a bad name so it was changed to the current type. Trust my I have bought enough of them I'm wrong there is a nother one on the market but the gearing is the same it's just much much stronger and a french chap is developing them but there not cheap at about 3500 euro's each.

Given the revs vs speed on the original post I am assuming that he still has the original IRD in the XEDI. You are right about the fact that there is only one IRD on the market now but if you went to a wreckers you could end up with an old one. The difference in revs vs speed between to two is about 300 rpm at 100 kph. In April my original IRD failed in my 98 XEDI - new parts were too expensive (half the cost of the car) so I was able the source an IRD, Viscous Coupling and rear diff out of a 40,000km TD4. Cost was a third of new. I thoughly researched gearing issues because I had concerns about not suffering the same problem again - before fitting, it was obvious the gearing in the newer IRD was different from the old one and when put in the car revs at 100kph dropped from about 3000 rpm to about 2600-2700RPM - is quieter and gives better fuel consumption. As I said if revs are about 3300 at 70mph - this indicates the original IRD is still in the car and some alarm bells should be ringing - when is my IRD and VC going to fail? Solution - change the IRD now to the new one - it will reduce revs and save on the cost of a new VC as well. Garry Quote Link to comment Share on other sites More sharing options...
jules Posted August 26, 2005 Share Posted August 26, 2005 I race as a Beamach Team driver. They supply all the IRD's that I have broken over the last three years competing I have a brand new spare VC but have never needed to repace it. All the parts I get come from Bearmach and I have never had any problems with the freelander parts and there much more reasonably priced.

chrisstevenson Posted April 26, 2006 Author Share Posted April 26, 2006 Well our IRD is finally on its way out [metal dust in the oil], despite a new VC. Never mind, a brand new IRD from Paddocks has arrived and I'll fit it next week, so this will give me a chance to see if it really does make any difference to engine revs at 70mph. Thing is though after speaking to Ashcrofts they told me that the only real difference is the pinion/crownwheel ratio so that the output to the rear diff is slightly faster or slower (cant remember), but this wouldnt have any affect on the output to the front wheels. Am I right in thinking that the front/left side driveshaft connects to the gearbox and not the IRD, so how could the IRD make any difference?

I have forgoten which one it is and I've sold the car so mmm bugger which one The emissions chip (EGR - exhaust gas recirculation) is in the top right hand corner of this picture, I think it is the one by the blue wire. I think it takes unburnt fuel from the exhaust and sticks it back in the engine to be combusted - reducing emissions of hydrocarbons but reducing engine goability[*].

chrisstevenson Posted July 17, 2006 Author Share Posted July 17, 2006 For info: Changed the IRD, it took 3 of us about 4 hours but that did include changing both front struts as the shockers were carp - the job wasnt as bad as I was expecting, its a little fiddly trying to get the new IRD into place but probably easier if you have access to a a hydraulic lift. Hasnt changed the issue of high engine revs at 70mph+ though. Fitting bigger tyres did help bring the revs down a little though. Quote Link to comment Share on other sites More sharing options...
Andy Posted September 5, 2006 Share Posted September 5, 2006 i dont know freebies in detail but i doubt changing the IRD would lower the displayed revs/speed combinations. the speedo would be calibrated for the original gearing & still displaying what it would do with the original IRD surely? unless the speedo pickup is after the IRD in which case im wrong.

angie Posted November 3, 2006 Share Posted November 3, 2006 [hi i have 51 reg V6 freelander steptronic. Lovely car but has started sticking in gears not changing up properly and clonking. Today just cut out on me and would not move, no gearbox warning lights have come up, but if you turn it off and on it will start to go again. Been told could be sensor. does anyone know or can they help Quote Link to comment Share on other sites More sharing options...
