Whiteblock Flywheel Bolts

This question relates 960 B6254 engine in my 240 with V70 single mass flywheel and an 850R clutch.

I'm wanting to replace the flywheel bolts when I change the flywheel from the dual mass to the single mass. The only volvo part number I have is 9454743.

Anyone know whether the dual mass whiteblock flywheel takes the same bolts as the single mass??

I used to use volvoem.com for searching out part numbers for this sort of stuff. Is there a similar or equivalent online resource or do I need to get one of the parts CDs off ebay??

Any help greatly appreciated?

Cheers

If you look on the Volvo parts site: https://www.volvopartswebstore.com/...78&ukey_trimLevel=24645&searchString=flywheel

EDIT - meant to link the VCNA parts site: https://usparts.volvocars.com/a/Vol..._51507_7338226/Crank-mechanism/GR-423632.html

That is the correct number for the SMF used on NA 850's.

Make sure you buy the correct driver - I used the Matco version - CQ12M2

The WB flywheel bolts I bought look like they need a 11mm XZN bit...the 12mm I bought is too big.
The CQ12M2 driver p/n listed above is 12mm.
11mm is certainly not a common size, but looks like Amazon has one.
A T55 driver fits, but I'd like to use the correct tool.

*EDIT: don't assume the tool is correct.
I bought another 12mm XZN bit and it fits just fine.

Fair warning, this bit may or may not work:

Hi
I know it's been a long time since this thread was active.

what gear box are you using? And do you have parts numbers for the clutch and flywheel. Looking to convert my Volvo 960 2.5 with m90 gearbox to a single mass flywheel and clutch setup.
