      Hehehe. Yeah Zack, wondering what my Rubicon X has to do with any of this. You need to stay focused here.

        My buddy has a jeep that leaks, not nearly as effective for undercoating as my rover,but a pretty good attempt.

        Now, as far as this Fairey O/D on my rover turning into loose parts in the future.

        IF I was to use it rarely, and lets say it was disengaged would it still come apart and or would it mess up my new tranny?

        OR would I just be better off leaving it on my old tranny and installing the new one without it since it has that plate already on?

        Basically here is what I am asking, I rarely ever use the O/D anyways and have no problem not installing it on the new one. Especially if it can or will come apart and damage the new unit.

        Any opinions?

          I don't see why a Fairey overdrive would "come apart" and destroy your transmission, but then again, I don't have an overdrive.

          FWIW, in 11 years of hanging around the RN and G&R boards, I've never heard of an OD "coming apart" and destroying a transmission or transfer case. Perhaps others can shed come light on their Fairey OD experience over the decades they've been in service.

          What is it that makes you think your OD will come apart and destroy your newly rebuild transmission+TC?

          Perhaps you should send your OD to me, just to make sure nothing nefarious occurs.

            The gears mesh somewhere or the OD would not do anything to advance the gearing. As was pointed out before, they do come apart, I'm wondering if bits of metal will end up in the rebuilt tranny and damage it. I never mentioned the transfer case, but IF it can happen I would love to know before I get it back together. I could easily live without the Fairey.

            It would be great if we could just rebuild them instead of run them till they break.

            Kinda sad really,

              Faireys don't "blow" they just start screaming. It means the bearings are going. Then you have to take it apart to replace parts. While it's apart you'll want to put the end plate back on the transfer case so that you can still drive the truck. No big thing really, just that the things are fairly danty cmpared with the rest o the vehicl.

                Would you have or know where I can get more technical data on the Fairey? I would be happy to install the bearings and check out tolerances while I have it apart. Granted some parts are more difficult to get, IF I had access to detailed info on this unit it would be very helpful.

                This is my first semi-major upgrade to my Rover so I am flying blind somewhat. I would really like to do it right the first time

                  Presumably George RDS Parts has all the components in the Fairey OD since he is currently producing the ODs again.

                      I would like to thank you guys for your input. It helped make this job better.

                      2 days later, tranny assy swap is complete. It shifts very nice now.

                      Installed new speedo cable........IT WORKS!!!!!

                      I did not install the Fairey OD on the RN rebuild. Easy to install after I get it rebuilt, so for now I can drive my girl around.

                        Not much help in rebuilding, but the parts manual is here:

                          Thanks for the file. I called George about a rebuild......Probably do other things to the old girl before I worry about the OD.

                          Not the highest on my priority list. No matter how I decide to get it rebuilt it will be expensive for what I will gain from having it in my truck.

                            BTW, I have a few tidbits to add before I leave for awhile.

                            I have put 100 miles on this thing, in 4th gear............ she is slow now, since the RN tranny assy swap and thought I would post some observations.

                            1. All linkage was perfectly adjusted and it works like a new one.

                            2. No oil leaks anywhere. Only 2 slight seeps but not enough to drip.

                            3. Other than the price and how little the core is worth, considering return shipping, I am more than pleased with the quality of this unit.

                            Now I have my old tranny assy that needs a 1-2 synchro but works fine otherwise. I'm thinking take it apart later and fix what I know needs replaced and sit in on the floor to age like a fine wine.

                            Or is it even worth it? I will never wear the new one out in my life time so is it even worth the time and effort to mess with?

                              Spend whatever time and money you would on that in pursuit of a clean 1990s vintage Range Rover Classic.

                                I am about ready to send my Fairey OD to George for a rebuild. But It appears he is closed. That is all his website says anyways.

                                I have 2 questions for you guys.

                                I bought the currently installed tranny assy from RN and it obviously did not have a Fairey installed. My removed tranny assy still has that Fairey OD unit hanging on it at this time.

                                Here is my first question, IF manage to get this OD rebuilt, what is required to install it on the RN rebuild in my Rover now? Isn't the drive gear in the way now? Would I have to remove anything internally from the RN tranny to be able to install a rebuilt OD?

                                Hopefully I explained that good enough.

                                And what is the deal with rovers down south? Are they out of business or just shut down temporarily?
