I noticed you didn't install the metal tube that feeds oil down to the front bearing. Is that not needed, or did i miss something? Thanks for the incredibly detailed video.
@maladroitmechanic 3 ай бұрын
@robertfanning2351 As I understand it, not all cases had these tubes. In fact, I have never opened a case that has one. If anyone has more information, please comment.
@robertfanning2351 3 ай бұрын
The tube runs from the front bearing to a hole in the case that leads to the low range unit. It attaches to a half round sheet metal collar. I believe the unit i have is pretty old, it only has a breather cap on emergency shifter cover.

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 9 ай бұрын
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 [email protected] if you like.

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

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

@@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.

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

I have a question. I have 2 of these. The manual says to put a quart in the reduction. Does that oil mix with the transfer case oil at all or is it a separate unit?
@cowboyonaboat Жыл бұрын
I asked this same question on the IFSJA forum. Waiting on conformation from the FSJ community. I believe the low-range reduction unit fills to a certain level, then overflows into the transfer case.
@maladroitmechanic Жыл бұрын
There are 2 holes in the case where the low range attaches so the fluid can pass back and forth between the main case and the low range unit. I think the only reason you need to add a pint to the low range is that the main case fill port would overflow if you try to add it there. I suspect you could add the entire amount of fluid through only the low range fill port but I have not confirmed that.

I'm not finding your link the the vacuum actuator retaining spring. For some reason, it was the only part not in my transfer case.
@maladroitmechanic Жыл бұрын
Thanks for pointing this out. I need to update the parts list. It is difficult to find exact replacement springs but I identified replacements that are similar. The short vacuum actuator spring is probably the most common missing part from the QTs. The replacement is almost identical to the original except the ends are not ground flat which also makes it slightly longer. I use a file or sandpaper to flatten the ends and the length is then very close to the original. Since you do not have the original to compare, the new spring is 0.38" long and the original is around 0.35". The spring would probably work just fine without grinding the ends flat but it is easy to do. Here is the link. www.thespringstore.com/pc035-188-6500-sst-0380-c-n-in.html
@ericpierron3994 Жыл бұрын
Shame that they have a $40 minimum on orders. I wonder if a spring is actually necessary for the retainer, or if a solid pin of sorts could be put in its place? I'm already changing a few things ....part time kit, vacuum delete and cable shift on low range.
@maladroitmechanic Жыл бұрын
Yes, that is unfortunate. Certainly, there are other ways to retain the actuator. I have seen a set screw in place of the spring. If you want, email your address and I'll mail a spring to you.

Mr. Maladroit THANK YOU, THANK YOU, THANK YOU! You bet there are humanoids out there that will benefit from your time, knowledge, effort and research. I am one of those humanoids. Your series of videos are extremely informative and entertaining. I will be doing a complete rebuild of my Borg Warner 1339 and adding the Mile Marker 4x2 kit. I was worried about finding the unobtainium bearings but no more. I live in El Paso, Texas and I have a source for parts in Chaparral, New Mexico (A Little 4x4). Not a plug. He is my honey hole for classic jeep parts but I know he doesn't have everything I need and that was my main concern until I stumbled upon your videos. My build is a 1976 Jeep Wagoneer Custom, 401/Th400, 95% original one owner beauty. Motor and tranny are done and next is the t case. I sincerely appreciate your videos. Keep up the great work and hope to see more in the future. Good day sir.

Good luck with the build Tony and thank you for the kind comments. I have an update video in the works, but until then, be sure to check the OD of the snap-ring in the large Advanced Adapter bearing. It may be larger that the original and cause some problems, but you can re-use the old snap-ring. Also, I put a few of the custom sleeved output shaft bearings on ebay if you need those. www.ebay.com/itm/304759394548?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=PXaXMlwuQfi&sssrc=2047675&ssuid=&widget_ver=artemis&media=COPY

The TH400 output shaft is the same length for both the 1305 & 1339. If you watch Part 1 I try to show that the drive hub on the 1305 and the planetary gear in the 1339 mount in the same location with the same snap ring. The TH400 shaft engages the drive hub and planetary to the same depth.
