acfortier Posted September 15, 2021 Share Posted September 15, 2021 Is this a direct swap? Are there any changes in the individual gauges from '91 to '96 that would make them inoperable? I broke the needle on my gas gauge and got a cluster from a '96 XJ in the junkyard, but the needles on the '96 are whiter than those on my '91, so thought about swapping everything over. Tach should work, since it came from a 4.0... I would think everything else would work? Would the speedo be off? Link to comment Share on other sites More sharing options...
Big Dan Posted September 15, 2021 Share Posted September 15, 2021 Edit - Disregard, you said 91. I'll let an HO guy chime in Link to comment Share on other sites More sharing options...
eaglescout526 Posted September 15, 2021 Share Posted September 15, 2021 I don't see why it wouldn’t work at all. Should be a direct plug n play honestly. Link to comment Share on other sites More sharing options...

eaglescout526 Posted September 15, 2021 Share Posted September 15, 2021 I don’t see why not. Be odd if Chrysler did that. Just the Renix and HO years are what we know to be different except for the temp, oil and volt gauge are the same. Tach might be too. I have a HO full cluster if you ever need more parts. Can’t confirm the year Link to comment Share on other sites More sharing options...
acfortier Posted September 15, 2021 Author Share Posted September 15, 2021 The real question is, how can I swap in the new odometer (which reads 186xxx) to match what is currently on my odometer (231xxx) without spinning it by hand, which will probably take me hours, lol. Might just have to keep the old speedo with it's yellowish needle. Link to comment Share on other sites More sharing options...
eaglescout526 Posted September 15, 2021 Share Posted September 15, 2021 Renix years seem to be the only one with a modifiable speedo but I’m sure you could pull the speedo face off with the needle and swap needles around. I can take my parts cluster this evening and confirm this if you would like. Link to comment Share on other sites More sharing options...

I think the only way to recalibrate the speedo if the needle is removed would be to use a GPS app on my phone and put the needle back where it should be... which doesn't sound like fun. 9 minutes ago, jeeptec1 said: 91 is obd 1 96 is obd2 May not working.

I’ll give it a shot. I took two 84-86 speedos apart but haven’t tested their accuracy yet. The center has a natural return position which as long as you leave the needle there and put it back, it should remain the same. Link to comment Share on other sites More sharing options...
acfortier Posted September 15, 2021 Author Share Posted September 15, 2021 I thought about the natural return position, but I wasn't sure if that was stopping because of the rubber piece that stops the needle. If the needle isn't there to stop it, it may keep going? Link to comment Share on other sites More sharing options...
eaglescout526 Posted September 15, 2021 Share Posted September 15, 2021 The older ones don’t seem to have that stop. I think that’s to stop it from spinning backwards as the Renix ones do run backwards when in reverse. Link to comment Share on other sites More sharing options...
ghetdjc320 Posted September 16, 2021 Share Posted September 16, 2021 I can confirm the 96 cluster works just fine in the 91. All 91-96 xj/mj clusters are interchangeable and there were no canbus (obd2) clusters until 97 in the XJ. You can modify the odometer if you are very gently at working with tiny plastic parts and work gears. You’ll need an exacto knife and some heat to remove the worm gear and then the odometer cylinder. You’ll have to move the mileage forward to get to where you need to go. Link to comment Share on other sites More sharing options...
Minuit Posted September 16, 2021 Share Posted September 16, 2021 I have a 96 full cluster in my 91. It will make things extremely easy if you ever want to use the UK market 125mph speedometer. Link to comment Share on other sites More sharing options...

Didn't know if I want to try to cut through/break that to get the cylinder out... Link to comment Share on other sites More sharing options...

Yeah there are 4tabs on that cylinder that index the numbers and prevent them from being turned until you pull the whole cylinder. If you carefully heat the ends that hold the stew rod it will come out smoothly. It’s just a bit tricky Link to comment Share on other sites More sharing options...
acfortier Posted September 16, 2021 Author Share Posted September 16, 2021 I got the whole cylinder removed, but there isn't a way to move the individual numbers--it's like there's some internal mechanism that's holding them in their proper place. At least I can spin it a lot faster? Link to comment Share on other sites More sharing options...

I'll give it a shot again, but didn't want to break it. Or, I guess I could rip out the other odometer and plop it into this one. Link to comment Share on other sites More sharing options...
87MJTIM Posted September 16, 2021 Share Posted September 16, 2021 There is a "C" clip on the shaft. Remove that clip. That will allow you to spread the counters apart. You can then rotate the counter to the proper numbers - one at a time. When done, you put the clip back on and reinstall everything. Link to comment Share on other sites More sharing options...
acfortier Posted September 16, 2021 Author Share Posted September 16, 2021 Doesn't look like there is a c-clip on this one: Link to comment Share on other sites More sharing options...

eaglescout526 Posted September 16, 2021 Share Posted September 16, 2021 This looks like the same issue I had with the 84-86 clusters. I just ended up swapping the cylinders around to the speedometer I wanted. Link to comment Share on other sites More sharing options...

Wasn't too hard to get the cylinder out of the first one, and I think it'll stay in place once it goes back in. 53 minutes ago, 87MJTIM said: Hmmm...mine has a C clip.

acfortier Posted September 16, 2021 Author Share Posted September 16, 2021 Well, I don't think I'm going to swap them. The new cluster has a different setup than the old one. You can see the difference in the two speedometers: Link to comment Share on other sites More sharing options...
