Steve It's not quite as simple as that, hole's on both are similar pcd but not in alignment so it needs a thick spacer to get all hole's in, 1 uz side will need to be held with Allen bolts first then lt77 offered up Regards Stephen Quote Link to comment Share on other sites More sharing options...

steve b Posted August 13, 2023 Share Posted August 13, 2023 I was thinking take the LR bell bolt face off all together then cut the Lexus housing bell and bolt flange at the right length to fit then weld up, doing away with an adaptor lump ?

Steve I think from memory you'd still need to make a spacer because the LR is quite thick and the A340 bell housing drops down in diameter quite quickly so may not offer the necessary clearance.

Worth a look though as the spacer would only be a plain ring to weld each side with this scheme Steve Quote Link to comment Share on other sites More sharing options...
Ed Poore Posted August 13, 2023 Share Posted August 13, 2023 Versus just drilling and tapping a few extra holes? It has the downside though that you've introduced a "custom" bell housing into the mix to replicate or replace if you need to it would need two more gearboxes.

dangerous doug Posted August 13, 2023 Share Posted August 13, 2023 As you have the lr housing and reference holes now, could you not section some 1” steel up and weld it together using the bellhousing as a jig? You can flatten it off with a multi setup on the mill or a rotary table Quote Link to comment Share on other sites More sharing options...
jad Posted August 13, 2023 Share Posted August 13, 2023 You would also then need to find somewhere to mount the clutch slave cylinder. I can send you my cad if its at all helpful. It was almost perfect.... 52.1mm though. I looked at the spacing from the face of the flywheel. 2 bolt holes didn't line up (internet borrowed dimensions.... Might have been for a different sump design. Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted August 13, 2023 Author Share Posted August 13, 2023 Taking on @steve b's comments I'm going to have a look at cutting a 200tdi engine housing that gearbox mates onto and make a flange out of some 8mm chequer plate for the 1uz side of things hopefully be able to tig something together that does the job and looks half decent........ I'm also part way through making a mould for casting.....couple of options or I could spend a grand......not happening, no way I have a reputation to maintain...lol Regards Stephen 1 Quote Link to comment Share on other sites More sharing options...

Ed Poore Posted August 13, 2023 Share Posted August 13, 2023 And it didn't fit properly which reminds me I need to pick up the flywheel from the mate who bored out the centre for me... 1 Quote Link to comment Share on other sites More sharing options...

Maybe if it was a drag racer with hard launches I might be a little concerned. Quote Link to comment Share on other sites More sharing options...

Just a 1000 pound flange made😁😁 No what's depressing is Stephen made the bit that didn't fit before anyone could blink (the flywheel). When I was thinking of fitting the 1UZ to the Sandringham then I was looking at doing what Stephen had but my lathe wasn't anywhere close to being big enough. Then plans changed and it was being dropped into the Defender and oo look there was an off-the-shelf adapter. I'm drastically time poor(e) at the moment and have been since I moved down here so I had some spare cash and thought why not. Kit arrives - cut off the ring gear from the flex plate and heat it up as Stephen did to drop it on - knock supplied spigot bearing in, bolt up adapter plate find that four bolts are the wrong thread - ah well there's plenty in there for the moment, I can source some later. Right - time to put the flywheel on... Oh... Doesn't fit over the crank - the centre bore is too small. Email Shabs and go through some measurements and the short version is he's adamant that there must be something different with my engine / crank because he's never had an issue before. Hmm., wonder who cocked up a measurement - someone turning out a handful of adapters a year or Toyota who built over 250,000 of them from the 1980s to ~2000. I mean they built 900 prototypes FFS! 1 Quote Link to comment Share on other sites More sharing options...

I know what you mean. The reason, that i allway's take the hard way of fabricating something.. Like Stephen does. It seems as if there is less and less knowhow at companies that should know what they are doing... And if it's not right, they just point a finger Quote Link to comment Share on other sites More sharing options...
