Triumph TR6 Differential rebuild - Part 1 - Dismantling and Assessing

I've replaced seals and some of the bearings on a few TR6 diffs before, but I haven't gone as deep as I did this time. In this miniseries we will go further and we will replace also one of the pinion bearings and the carrier bearings and we will have to readjust shims and spacers in order to get to the correct gear positions, backlash and preload. It was an interesting experience for me and I hope it will be the same for you.

Excellent video. I hope I don’t need to do this anytime soon, but nice to have a crack-a-lacking video to walk us through. Thanks!

Elin, when assembling the diff, you can put the housing in your press, it will aid in shimming up the carrier bearings ! Regards, Sandy 🔧🏴󠁧󠁢󠁳󠁣󠁴󠁿

I like that you use the Rubbermaid lid as an oil catcher. Makes perfect sense. Thank you Elin. 🎅🎅

Thx Elin

Awesome little automobile....The Triumph TR 6.... good video 😎.

[@jamesmathias5708]

I did mine last year with help. I only wish that this video had been available then! Looking forward to the next episodes....

[@larryp6814]

Just another great series! Thank you for the content.

[@charlesbaker4508]

Nice work Elin. Looking forward to the sequel(s). That big flat screen is a nice addition to the shop and showing the expanded diagrams is helpful. I’m hoping one day to change my diff ratio for a taller one if I can ever find a crown gear so these videos will come in handy.

I had thought of doing mine when I replaced the seals but was scared off by what I saw in diagrams. Thanks and i will watch for part 2. Great job

[@graemelliott3942]

Great job Elin!

[@nigelbarton8350]

Great start Elin, looking forward to the rest. It will be interesting to see what the planet gear thrust washers are like. On my MGB GT diff I did last year, they had disintegrated and were in bits in the bottom of the casing. This left so much slack for the gears to ride up and down the centre pin that it had nearly 90 degrees of backlash.

Hi Elin, Ive seen bits and pieces in the manuals but it always looked too complicated and needed special jigs, fixtures and measuring equipment. Look forward to seeing the next episode. Good luck from Spain!!

I just found another video where you changed the side axle seals. You had no trouble separating the hub from the axles in that video using the press.

[@RustyBeauties]

That was a 20ton press at my work place at the time. Mine is 12ton

[@davidwarr8600]

Hi Elin! It seems to me that you were pressing on the flange against itself. Hard to see in the video. I can’t believe that a 12 ton press couldn’t pop that out. On my GT6 the bearings on the axle shafts have to be pulled off with a wedge type puller if you have one. But if changing the bearings you may as well grind them off. The GT6 diff is a little different than the one in a TR6.

[@jaman878]

Believe it. Those flanges microweld themselves to the shaft. We had a 20 ton press and we needed all of that. They let go with an absolutely hellish sound. You definitely need to wrap your work with a blanket and the pillow is a good idea. I don't like the torch idea either because the shafts are heat treated. The best method to pull these shafts apart is a specially designed puller and an impact wrench. The shock of the wrench helps to overcome the coefficient to static friction by disrupting those micro-welds.

[@jimconklin8040]

So far, so good. I hope the square key is not screwed up, it could mean bad keyway in shaft as well. I had a real fun time doing the same, removing the flange, when changing my seals. I used a big press too. Are you sure the owner did not have all the play with the half shaft still on? Bad universal?

[@iceman9678]

I don't trust a mechanic that always wears gloves. Nice job getting in there.

Hello Elin , Always look forward to your videos . Please clarify a couple of items . Why after 40-50 years & everything is apart , is the pinion bearing not being replaced ? Have seen you add the differential drain plug a couple of times , but have to ask why ? Realize the intent is to quickly drain / replace oil , but realistically, who does that ? Went 40+ years without it . Summer driven only driven car , person could spring for a differential cover gasket every couple of years & do a good clean .

[@nigelbarton8350]

If I was replacing pretty much every other bearing, as Elin is doing here, I would for sure do that second pinion bearing as well. But as for the drain plug, if it is the same as the Stag (in terms of access I mean, not the diff itself) you have to remove the whole diff from the car to get the cover off. I’d rather have a drain plug to encourage me to change the oil regularly now it is al nicely rebuilt.

[@grandpar468]

Tanks for the reply . Personally think we would just be creating another leak point 😊

[@larryp6814]

…… I’d be guessing of course, but maybe these are the services his customer requested??

[@grandpar468]

Good guess on your part 😊Because I was told or paid to do something does not enlighten us to the purpose .
