Honestly, your time would be better spent correcting the plate you have. I don't think ACME is interested in correcting the issue because most people don't put enough miles on these conversations for the long term problems from misalignment to arise. If you can find yourself an R150, AX15, etc scrap case the slice is easy to make.
You'll see in the video I have already made a slice and I'm already in the process of correcting my plate. But it grieves me that I should have to, it's not a complicated issue to adjust their CAD drawings surely?
But it's a pretty sh@tty way to operate a business that 5 years on they haven't addressed this and are still selling a known defective item, that's not cheap.
It's a shame because on the whole it's a great design with all the collared studs and tapers to locate it perfectly.... it just locates it perfectly in the wrong place, lol

I thought the consensus was Acme had addressed the issues with their newer kits? I didn't realize the newer kits still had the alignment issues.

There are only a few tdi adapter plate builders. Acme is the only one I've heard of with these issues.
Maybe they sent me old stock to get rid of it, thinking that because im in the UK, it's good enough for us?? From what I've read, they addressed it with the Suzuki plate, but they certainly haven't with the Toyota one, at least, not from what they sent me?!
As said, it's a shame because, other than being a free mm out, that would be so easy to correct on their plans, it's a great and simple adapter.

Says he hasn't been active since 2019?
Probably got fed up with complaints, lol..... sorry, trying to see the bright side, cheers for your help anyway.
I guess all I can add is if anyone is gonna do this conversion, go for it.... it's seriously awesome.... just use someone else for your adapter.
If any one is interested, I can update with my bastardisation of my acme plate... other than that I guess I'l let this thread rest for another few years.... peace out, and thanks for your help 👍

Who all makes tdi to w56 adapters?

North West fab, doomsday diesel and diesel conversion specialists along with Acme are all I'm familiar with.

North West has the reputation for being the best in the industry.

TD Conversions is the only other company I can think of.

I have an Acme R150 adapter and had read that they had fixed the runout issues. I haven't had any issues so far but only have about 15,000km on my swap to date. What are the long term symptoms of this issue?

I'd love to see what exactly you did to fix the problem. I'm at around 60k km on my swap now and it just ate a second clutch. Bad vibrations, crunching sound coming from the bell housing, clutch doesn't disengage completely and shudders badly when engaging. Pretty sure adapter plate runout is the root cause, trying to get a good idea of what to plan for to fix the issue for good.

You should probably start another thread solely pertaining to what you’re after to attract those that have the info you seek

Little update on the effects of engine/transmission runout in an adapter plate. This is my second clutch, a Centerforce II rated for around 370ft-lbs and installed a little under 25k miles ago. Signifiant wear on the pressure plate fingers and throwout bearing, retainers for the clutch hub springs disintegrated and turned into shrapnel flying around in the bell housing, face of the flywheel eaten up from metal fragments, pilot bushing almost gone entirely. Transmission internals unknown at this point, but have parts on order to replace the input shaft bearing.




After talking to some local machine shops I have decided to ditch the ACME kit entirely and have put my name down for a Doomsday Diesel 15º clocked adapter kit.

I know someone who ate up two input shaft bearings with one of those adapter plates.
I don’t know if you’ve seen it, but Jimbote dialed his in. I believe he removed the dowels and welded them in place after centering it

Pretty much. Mine was an early plate without dowels. I centered the bell then welded dowels into the plate from the backside once it was all clamped down.

@jimbote do you have any photos or tips on how to check an adapter plate for runout? I should have a custom plate done by the end of this week or early next week and want to check it prior to full installation to make sure all is good. I have a spare bell housing and empty transmission case, but my mag base and dial indicator are far too big to fit inside the bell housing or in the input shaft bearing bore. Curious what setup you used to measure runout.

I don't but lots of youtube videos covering the procedure.
