i converted my freelander to a td4 from a v6.i drove for about 300klms and realized that the ird was in bad need of bearings and planetary shims.so rather than wait for shims to arrive to canada. i decided to install my perfectly functioning v6 ird today.it seem to work perfectly.
now the gearing between the two ird's are different.1.467:1 for diesel and 1.359:1 for v6.so my rpms with v6 ird at 60mph are slightly less than rpm2000.at 80mph they are slightly less than 2500rpm.
with torque converter lock up at 50mph it revs at just over 1500rpm
maybe a td4 owner across the pond can compare these rpm figures.and see what differences there are if any.
for the short time i drove with the diesel ird i did not check the rpms
thanks
