duel mass will not fit??? is wiki wrong

[taylorstattoo]

hi ,, it states on the wiki that when using the m40 318is box, that you can use either the m20 skimmed with m20 clutch or the existing duelmass that is on my m52 engine already,, problem is the m40 box does not seem to fit tight, there is about 5/10mm left to sit flush against engine and after trying everything it seems to be that the duelmass clutch plate outer frame thing is hitting the bell houseing,, is thw wiki wrong or am i missing something here,,

thanks steve..

By far the simplest gearbox to fit to your M5x conversion is that fitted to the 318iS. This M42-specific gearbox will bolt straight up to the engine and remove the need for any Drivetrain modification such as different differentials. It is also capable of accepting the E36 clutch and flywheel if required, although it is recommended to fit the M20 flywheel.

i hope im doing something wrong as iv try`ed everthing and it seems to be to big for the bell housing..

I don't know whether the dualmass and the single mass M50/52 flywheels are much different in size but I was running an M50/52 ally flywheel on my 318iS with no issues at all.

[taylorstattoo]

its a m52 328 engine with standard bmw dualmass clutch,, the box is out of my 318is m40/42 i believe,, but like i said it seems to be too big,,,

[Kedge]

I suspect the issue is that you are using the dualmass. I've never hear of anyone using a dualmass flywheel for this swap.

[taylorstattoo]

right ok.. i did not know the m52 could come with either style clutch,, i thought they were all dualmass... also im sure iv read in here and other sites from people using both together,, i must have been getting it wrong somwhere,, lol.. so where do i go now as im running out of time in the garage im in,, do i have to use a m20 setup?? somone has told me befor but why cant you use the m40 setup??

[taylorstattoo]

anyone?

Bit of a stab in the dark but make sure you have your sandwich plate in (bit between the back of the block and the flywheel), more so though check your locating dowels make sure there not stuck in the block from the m52 gearbox and that the m40 box doesnt have them in still, basically you should only have two dowels in. Sorry I'm shite at explaining stuff . Hope this helps, personally I used m20 solid mass in my conversion.

Where in Cornwall are you? I could possibly lend a hand or two if needed

I can't see where it says you can use that flywheel and gearbox cominbation in the Wiki, to be honest the best thread to take information from is the sticky in this section found here:

I think your options are, use the 328i gearbox if you want to use your current flywheel, or get an E30 325i clutch kit, flywheel and starter motor.

i think the m40 box isnt the same as the m42?

[Motorhole]

right ok.. i did not know the m52 could come with either style clutch,, i thought they were all dualmass...

All M52s have dual mass flywheel and associated clutch. Most people who do the swap into E30 bin the dual-mass for an M20 flywheel & clutch. These need to be used with an M20 starter motor and either the flywheel needs skimming (to clear the sump) or a bit of the sump can be ground down out of the way.

this is from the wiki...

Gearbox
By far the simplest gearbox to fit to your M5x conversion is that fitted to the 318iS.

i've an m40 box on my m50 with the dual mass, no problems fitting it

have you got any pics of your build?? the box is only5mm or so away from fitting flush, iv got the plate in, and i tryed taking the clutch and plate off to see and it fitted up fine then....

looks to me like its the clutch cassing hitting the bell housing,, but cant feel or hear it catching just a few marks inside but could of been done taking it on and off,,, or the the shaft like piece at the back of the box around the toothed spine might be too long????

Im sure ive tried to fit an M50 box on the back of a 2.8 before and it hit the clutch, I expect its to do with the 328i using a 240mm clutch rather than the 220mm found on the earlier M50's and M20's etc

get an E30 325i clutch kit, flywheel and starter motor.

This is what you want to be doing, yes you will have to lay a bit more money out at the moment but it makes a big difference to the engine, accelerates faster and feels generally more nimble.

Im sure I have a decent used clutch kit/fly/starter I can put together if your interested?
