Thread: 200Tdi vs 300Tdi bellhousing bolt pattern?

Hmm - maybe I can answer my own questions:

This is a 200Tdi bellhousing prepped to fit a series Gearbox (one stud needs to be removed):


This is a 300Tdi bellhousing:



And this is the same bellhousing prepped to mate to a series gearbox:



I am not sure why the wings at the bottom need to be cut off???

So, it seems that the PCD of 200Tdi and 300Tdi and Series are the same, only the stud spacing differs. It also seems like a 200Tdi engine bellhousing would fit a 300 if you cut the same hole in the middle???

Anyone know what the wings are for on the 300 housing?

The wings have bolts which then extend back towards braces off the R380, bracing supports for the enormous torque I guess.
'edit: hang on a minutes maybe they go forward to the engine mount brackets, cant remebr right now - but thinking engine mounts ATMO'

Does this also mean that a 300 bell housing with some poke jiggery in the studs could be mated to a series gear case??? Flywheel clutch may need some finessing but if PCD are the same?

Yes it certainly can - have a read here: 300TDI flywheel housing mods - before and after photos

And here: http://www.lro.com/forum3/viewtopic....27236&start=10

(Though I personally would redrill the series bellhousing so I could use at least 12 of the 300Tdi bolts - not use only 9 like this guy did).

It seems that 300's are just as easy to fit to a series as a 200.

and they go forward

Any pics of these braces rick? So they run from the engine bellhousing to the engine mounts?

IIRC they go back to the block Ben.

I can get some piccies tomorrow.

If they are incorporated into the ingin mounts, I have a set of 300 mounts on the shed floor at the mo and could take some pics and dimensions if needed Ben?

Thanks for linkies on bolting a 300 to a series box. I am part owner/caretaker of a IIa wagon with some real australian history, it has been converted to a holden 6 (whichi s probably not a major problem ... but???) Soon Ill have an old flogged and dusted 300 taking up shed space which may indeed be a good match, sans hair dryer for a series!

Ben,
I just ducked out and had a squiz.
The 'wings' do indeed bolt to the engine mounts.
The mount which is bolted to the 300block incorporates some 5 ish mm plate which extends back to a bracket which picks up bolts through the flywheel housing wings. This steel engine mount then bolts to the rubber mount then to chassis.

As I mentioned above I have a set of these steel engine mounts seperated on the shed floor. I guess if you are bolting in a 300 you would get these mounts from the donor though? Unless you had a bare block donor engine?

I still think it is to stabilise and control the enormous torque pulses of the 300!
