The adapter would have to be another 6" longer to not cant either the transfer or the engine / gearbox. Their Merc version of the adaptor cants it over... and my adaptor makes the connection about 50mm shorter than theirs - and level. So in the case of the merc box it could have been done and not canted. I think the Merc version of the adaptor was the first as well so that part of the adaptor was 'wrong' to start with.

andyg365 Posted December 21, 2020 Author Share Posted December 21, 2020 Thanks for the comments but the gearbox and transfer box are already mated, I did that a years ago. Its the bog warner Tbox. What's the shortest length of rear prop that's advisible!?! Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted December 21, 2020 Share Posted December 21, 2020 It's not really about length to be honest, but angle. If you are running a lift, then it makes the whole thing worse.... So what's the setup? Quote Link to comment Share on other sites More sharing options...

From memory its 2" suspension lift and the body isnt lifted Quote Link to comment Share on other sites More sharing options...
andyg365 Posted December 24, 2020 Author Share Posted December 24, 2020 This is the adaptor plate for mating the transmission to the transfer box. Quote Link to comment Share on other sites More sharing options...
JohnnoK Posted December 26, 2020 Share Posted December 26, 2020 It doesn't get much simpler than that. Well done, that man! 1 Quote Link to comment Share on other sites More sharing options...

Tried and tested by others maybe? Quote Link to comment Share on other sites More sharing options...

I'm using the same props this time so will have to see! Quote Link to comment Share on other sites More sharing options...

Nice (but longish) solution. 🙂 I would add some plating to make it a box like construction with some holes in it to bolt it up. In this state it can flex a lot. 1 Quote Link to comment Share on other sites More sharing options...

Probably useless as a comparison but that headstock on the JCB is 2m wide. I'll try and get a picture of it next to a Tdi R380 for comparison. Edit: I think it's actually narrower. The width (outer edge of tyre to tyre) is 2m. Quote Link to comment Share on other sites More sharing options...

The outputshaft / flange of the autobox looks like it can made shorter. 🤔 Maybe remove the mounting for the donut and weld a new one on it closer to the autobox. Drawback is you need to alter standard parts. The plates are thick and the rods are strong.. but still... 😉 Quote Link to comment Share on other sites More sharing options...
Ed Poore Posted January 17, 2021 Share Posted January 17, 2021 @Carloz the issue with making it shorter is that the sump of the autobox then starts to foul the diff housing on the LT230. Pushing it forwards helps to clear that and means you don't need to cant either the gearbox or transfer box over (both which may introduce issues with oil starvation). 1 Quote Link to comment Share on other sites More sharing options...
Snagger Posted January 18, 2021 Share Posted January 18, 2021 I think you need to add walls on two sides at least. It’s not bending that you have to worry about but twisting. Even just some gussets would help, but two solid walls would stop any torsional movement from the torque loads in the transmission. Quote Link to comment Share on other sites More sharing options...

I agree to stay away from that kind of issues, in that way you from one thing into another. On 1/18/2021 at 5:56 AM, Snagger said: I think you need to add walls on two sides at least.

Adding walls on only two sides doesn't stop twisting. Boxing it is the only way to get it free of twisting. Imagine a U-profile, that is 3 sides closed, it will not bend much but will twist to great extend. Close the 4th side and it is a total different story. But of course, imperfect contructions can be made strong enough when you use enough material. 🙂 Quote Link to comment Share on other sites More sharing options...
