" you don't need to remove the yokes to split the case" Exactly what I was looking for, thank you.

You are welcome!

Incredibly helpful for someone clueless with TCs. THANK YOU for the thorough video.

[@maladroitmechanic]

Glad it was helpful!

Great timing, just took mine apart. All cleaned up and read to assemble so will watch all your videos before. Am doing the 4x2 kit and new chain/seals. I am doing a 1305 but my Honcho has a 1339 which i will swap. I will do the original after a swap. My case didnt have the o ring gasket and i am not sure the vintage of the 1305. The 1339 is in a 1979 so will see next year if it has the rubber o ring.

Thanks for the comment! I now have the output shaft bearings that I have been waiting for so the final assembly video is coming soon. A Honcho build would be so cool....maybe that is my next project.

[@jm-ve8ry]

Any intertest in selling your 1339? I have a 79' wagoneer.

[@roberteve292]

@@jm-ve8ry sorry, but that is the original for my J10. Havent even put the 1305 into it to see if it works with the the part time kit in it. There should be some around as people seem to want to get rid of them .

Great video's I do have a problem with my chain has 48 links and it is to loose so I found another good morse chain 48 links put it on still loose both the chain sprockets have 48 teeth I talked with Ryan at BJ's when I ordered my rebuild parts they have 2 chains one with the standard 48 link and one with 46 link for 16% over drive would you know where this over drive is located and how many teeth should the standard chain sprockets have thank you

[@maladroitmechanic]

Thanks! The MileMarker part-time conversion kit came in 2 options, normal or overdrive. The kit replaces the QT differential with a solid sprocket. The normal sprocket is the same diameter as the differential and has the same number of teeth, 48 or 49(don't remember exactly). The overdrive sprocket has a smaller diameter and less teeth, 41 I think. So, of you have an overdrive sprocket, it should be very obvious. It sounds like you have a non-overdrive sprocket or stock differential. I need more information to speculate on your loose chain. You can send pics to [e-mail] if you like.

@@maladroitmechanic thank you I will take some pictures the jeep is the original all wheel drive that you

[@roberttrujillo-s8w]

great video's I have been having a problem with my 1339 and that is when climbing and under a load I get a load banging sound like banging with a hammer and then the reduction unit pops into neutral I had the same problem with my other transfer case even when I switch on the e-drive any advice as to what may be causing this problem

[@maladroitmechanic]

Are you certain that the bang happens before it goes into neutral? Shifting to neutral under load probably makes a loud bang.

[@roberttrujillo-s8w]

yes I shift into low range on flat ground and then start to climb at the steepest part when the front wheels seem to break traction on the rocky surface it starts banging the shift lever pops into neutral I have to coast down to a flat spot turn the jeep off shift back into high and go on up the hill I still get a bang in high but if I hold the gas just right I was able to make it up the hill @@maladroitmechanic

[@maladroitmechanic]

@@roberttrujillo-s8w I would first check the low range shift linkage. It should not have any tension on it in Hi or Low range because the detent ball holds it in gear. I wonder if you have worn engine and transmission mounts. This could allow excessive torque movement under load which could pull the shift lever.

[@roberttrujillo-s8w]

I have new engine mounts I will check the transmission I checked the linkage everything is good there I also adjusted the trnny linkage everything is good there it starts to bang when one of the front wheels looses traction so I stopped on a slight slope in low range give it some gas and it started banging so I stopped and went up in high the old transfer case started to bang a lot it was worn out lot of metal in the fluid so I picked this one up at the jeep wrecker ran it for a month and changed the fluid it was clean mean while I will check the transmission mounts thank you @@maladroitmechanic

[@roberttrujillo-s8w]

motor mounts and transmission mounts are in good shape as well as the transfer case stabilizer they were out in new when the shop installed the transfer case

[@flywiseman]

I am looking at a CJ7 with this transfer case. Is there any concern that if it ever breaks i wont be able to find parts?

[@maladroitmechanic]

Yes, this is a concern with anything that has been out of production for many years unless the aftermarket carries the torch.
