landroversforever Posted September 25, 2015 Share Posted September 25, 2015 Wondering if anyone can shed some light on the following. I'm locating the transmission in the chassis and my only reference is the mount for the LT230 as I'm using the Mercedes engine and box. Now, with the LT230 sat on the mount with a solid aluminium version of the bush (only for build so I've got solid references) it sits nose up slightly. Can anyone confirm how theirs sits in relation to the top of the middle chassis section if that's classed as 'level'? Does the driveline on a defender normally point up towards the front? Which part of the box (if any) is level left-right looking from the rear or front? I need to know what my 'horizontal' is for setting up how the bolt patterns on my adaptor will sit in relation to each other. I should probably add that I'm working from the 200tdi position of the transfer box with 200tdi type rubbers and 200tdi type mounts on the chassis. Thanks in advance all!

Landy-Novice Posted September 25, 2015 Share Posted September 25, 2015 if its any use, i can get you some photos of prop angles on a std 200 90. could help you guestimate the angle to mount lt230? Quote Link to comment Share on other sites More sharing options...
landroversforever Posted September 25, 2015 Author Share Posted September 25, 2015 Not sure prop angles would be much use, too many things to guess then! Thanks anyway Quote Link to comment Share on other sites More sharing options...
landroversforever Posted September 25, 2015 Author Share Posted September 25, 2015 It sits like this on the mount: Quote Link to comment Share on other sites More sharing options...
Landy-Novice Posted September 25, 2015 Share Posted September 25, 2015 front flange is 100mm from bottom of chassis rail if that helps? Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted September 25, 2015 Share Posted September 25, 2015 I believe they sit slightly nose-up on the Tdci models? Only problems I can think of at the moment would be possible oil starvation to the front output bearings and propshaft angles perhaps needing a slight tweak.

Team Idris Posted September 25, 2015 Share Posted September 25, 2015 It all points up on the RRC. The manifold is compensated to keep the carbs level. To miss the sump it's likely they kept the same concept on every 'coiler' after that. Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted September 25, 2015 Share Posted September 25, 2015 Yep, all Coilers I've seen has the engine pointing upwards, the only thing that would worry me here is angle on the front prop. Lubrication shouldn't be an issue seeing how high the oil level is in the Transfer box. But if it would suit your Merc engine better to change the angle either way, I wouldn't hesitate to do that, the transfer and mainbox will do just fine Quote Link to comment Share on other sites More sharing options...
landroversforever Posted September 25, 2015 Author Share Posted September 25, 2015 From an engine point of view, the higher the engine the better as the sump bowl is over the top of the axle currently! However as the front axle is going to end up quite flexible I hope, I may have issues with the front transfer box UJ. Thanks for the thoughts on the front-rear inclination. Any thoughts on the side-side? I assume the top of the high/low selector housing is level side-side? Quote Link to comment Share on other sites More sharing options...
Dave W Posted September 25, 2015 Share Posted September 25, 2015 I'd agree with the thoughts regarding front/rear angle, that looks "by eye" to be about normal in my experience. I think that's why one propshaft is normally phased (front one IIRC) and the other isn't. You are correct re the side to side orientation, the hi-lo selector should be level although I doubt it's all that critical. Quote Link to comment Share on other sites More sharing options...
elbekko Posted September 26, 2015 Share Posted September 26, 2015 I'm thinking the nose pointing upwards may help a little with rear prop angles on a 90 as well. Quote Link to comment Share on other sites More sharing options...
ToyRoverlander Posted September 26, 2015 Share Posted September 26, 2015 Any thoughts on the side-side? I assume the top of the high/low selector housing is level side-side? Keeping the output flange at a 90 degree angle with the chassis would be good idea. A slight misalignment of 1 or 2 degrees is no biggie.

landroversforever Posted September 26, 2015 Author Share Posted September 26, 2015 Thanks all! Couple of things to check and then I can crack on with the adaptor! Quote Link to comment Share on other sites More sharing options...
robertspark Posted September 26, 2015 Share Posted September 26, 2015 How are you making your adapter if i may ask? Flange plates and welded tube or a machined adapter? Quote Link to comment Share on other sites More sharing options...
landroversforever Posted September 26, 2015 Author Share Posted September 26, 2015 I'll be machining a billet one. Probably in two parts, with the Lt230 flange side of the adaptor bolting through the other part onto the merc box. Quote Link to comment Share on other sites More sharing options...
landroversforever Posted October 15, 2015 Author Share Posted October 15, 2015 Another question to add to this then... How does the position of the LT230 change with regards to 200/300/td5/puma? Are the mounts the same but holes in the chassis different or are the holes the same and the mounts different? Quote Link to comment Share on other sites More sharing options...
wanger Posted October 16, 2015 Share Posted October 16, 2015 Not sure but we've measured up using my tdci 110 and my e300 and it looks like it will all line up nicely. I always though the TB was always in the same place. Because you can change props around from 200 to tdci Quote Link to comment Share on other sites More sharing options...
landroversforever Posted October 16, 2015 Author Share Posted October 16, 2015 I don't think it is, as props are different I'm sure. Quote Link to comment Share on other sites More sharing options...

daveturnbull Posted October 16, 2015 Share Posted October 16, 2015 I know 300tdi and td5 props are the same lengths, 200 is different. Not sure about TDCI Quote Link to comment Share on other sites More sharing options...

wanger Posted October 16, 2015 Share Posted October 16, 2015 i have a early...B reg 110 chassis and a later tdci chassis in the house at present. i'll measure the TB position on both and report back. We are talking TB position not prop length. Props are diifernt due to diff nose length, TB etc. Quote Link to comment Share on other sites More sharing options...
muddy Posted October 16, 2015 Share Posted October 16, 2015 No transfer box moves, if you have the standard r380 position this is approx 2" further forward than the LT77 position, thus if you put a salisbury axle on a R380 90 you can use an LT77 rear propshaft Will..

miketomcat Posted October 16, 2015 Share Posted October 16, 2015 Front prop length gives you position of transfer box as all chassis have the front axle in the same place with the same axle/diff. Mike Quote Link to comment Share on other sites More sharing options...
wanger Posted October 16, 2015 Share Posted October 16, 2015 i'll measure from the hckey stickbush to the TB mount on both. Front props cn change length...salisbury axle?! Quote Link to comment Share on other sites More sharing options...
