Great vid , thx Richard. Aligning will be a huge improvement, I've been through this with Rexroth hydraulic motors, running the spline in an oil bath was the only 100% fix
Maybe I missed it, but what material is the adapter shaft made from. Also how are the splines lubricated at the t/case end? Looks a lot like fretting corrosion….
Hey you seem to be having a lot of issues with the serptine setup, may be an idea to talk to dandy engines or Moe engines or power house engines, they build a lot of modified high rpm speedway barra engines they may be able to help you out with ideas or products so you don't have further issues
@@nordic5490 HuH 🤔? What are you babbling on about? Talk’n about a better more reliable serpentine belt setup. Not drag car & race car engine mods that effects the roadworthiness. Use ya brain 🧠 Derrrrrrrrr
Working towards an 8HP swap in my 80 series, going with a Domi-works adapter which replaces the transfer case input shaft doing away with spud shaft. As for reliability time will tell.
@@bronsonmercieca2120wonder how it compares as the cruiser one which is off set to the patrol diff input, vs patrol transfer to patrol diff at a bit shorter but straighter?
the design of that adapter isn't optimal. i run similar kinds of adapters in jeeps and the adapters i use run two large bearings on the spud shaft and are actually shorter than the adapter you have there. the adapter is designed to be lubricated using the gearbox oil in my application. if you want to see an example of what i'm talking about take a look at "novak th400 to d20 adapter" or the one i use which is "novak ax15 to d20 adapter" something to look at if you continue having issues or as improvement to future adapters if he is serious about building better adapters.
I have an NA barra in a custom Extra cab long wheelbase on airbags gu patrol. Had heaps of problems with the g box adapter. After countless times removing box l found the adapter was out on one dowel pin by 1.8mm. Very frustrating. Also had the same problem you have with the serpentine built. My high mount Alternator bracket (mine) was a bees dick out, came off at revs smashing the water pump and jamming in the crank pulley. Would not have a new 4x4. Love working on it and making it mine
They are awesome mate! Maybe If they made a little less power then I wouldn’t have this problem 🤣 apart from that though the Barra isn’t at fault at all, the gearbox output is still mint, better than the 79 input!
designed and built .....not reliable 4wd in any way why would u even build something like that in the first place .....waiste of time and money .....toyota engines into Toyotas for a reason in the first place......i will stick to my poverty pack 80 series 1HZ n/a keeps on going and going a reliable touring 4wd simple is better in many ways my 2 cents worth
I'm a mechanical engineer as well, and I can tell you now that fixing the alignment alone won't solve the problem. GU patrol 5th gears failed after 50 - 70,000 kms with this same fault, and the cause is a loose fit spline that allows fretting wear. Lots of patrol gearboxes failed until Nissan released a new design main shaft with much tighter tolerances that was an interference fit. You can google it. Heaps of pics of the failures of the spline are on the internet. The spline needs to have no play at all. You could try loctite 680 as well, to prevent the spline rattling. I know because I rebuilt my GU gearbox with the new parts released by Nissan.
I’ve had a few Barra issues in the past and Brett gave me some help. Very smart and knowledgeable man.
Great bit of work on the mill and even better seeing how nice it all lined up in the end
Cheers Rich, love the detail!!! Hope others are watching. Could watch this all day long. Great ep
Brett is a true legend knows his shit and humble about it 💪👌

It would be good to see a barra swapped Ranger on here.
You do one clown.
Am i the only one impressed with ol mates thumb work on the alan key?
Hopefully it's all sorted for you now, great video thanks 👍
Land Rover had the same issue with input spline wear, they cross drilled the input gear to allow oil to get to it and it fixed the issue.
Wow man really knows his stuff what a legend !!!
Good ep mate, looking forward to the next one. 💯

Build a custom 4wd they said it will be fun they said 🤣

This car is fully engineer approved and road legal. The others are not.
@nordic5490 uhhhh yeah I know, but engineering doesent cover the serpentine setup and making it reliable

Should make mention the video was informative and something that has not been covered elsewhere, thanks for sharing.
Hi, are buying your adaptor from a supplier in Aus, or buying it from overseas?
Already purchased one from the the first batch imported by 8 Speed in QLD. First impression is finish on adapter and input shaft look the part.
Should mention the Domiworks adapter is for BMW 8HP to Toyota transfer.
Although the next part of the trip is no doubt in the past, hopefuly Back to the Future Rich's holiday goes smooth from here. Thanks for sharing
Another great informative video.
Why didn't you use a patrol transfer? I'm sure you cover this but I can't remember.
The 79 transfer is significantly shorter than the patrol transfer which allows a longer tailshaft and better uni angles
Or just buy a Patrol.

How hot does the fluid get with the turbo right there. I get fade had to move to bottom mount turbo.
Would’ve been better with a 1hd-fte grouse engines mate. Barra’s good too, just say’n.
Can you tell us where the dodgy one was from, so we know to avoid the issue ?
We all know who makes that shaft.
It's not a matter of if it's a matter of when.
Why is the old shaft rusty?🙄
It's not rusty. This is fretting corrosion. Google Nissan patrol 5th gear failure pics. All splines have this rust colour. (iron particles)
Too much power! 🦘🤷♂️😳🙈
Just shit gear, thats all thats available nowdays
Barra are so good
They are awesome mate! Maybe If they made a little less power then I wouldn’t have this problem 🤣 apart from that though the Barra isn’t at fault at all, the gearbox output is still mint, better than the 79 input!

Yeh keeping everything standard would make for amazing viewing on RUclips
I think you're missing the point of his channel...he designs and builds unique things...
Maybe he likes to do the speed limit up hills
If the company who supplied the transfer conversion built it correctly there wouldn’t be a problem many people have had the same problems
Why are you here?
