Engine Swap Questions: 603 3.5 to 603 3.0

[ChiefRider]

I'm in the middle of building up the new OM603.960 3.0 engine, using many of the 3.5 engine parts.

First question- is there anyone who has done this and used the 3.5 litre flywheel? I am using the 3.0 litre flywheel, so no worries there but the 3.5 flywheel is radically different, and much lighter. Just wondering what experience anyone may have had running the 3.5 flywheel.

Second- The windage tray from the 3.5.

I am using the oil pump and pan from the 3.5, and so am installing the windage tray. I know that tray screws can work lose and get sucked up by the oil pump. Will Loctite be sufficient to prevent this? My original 3.5 had this happen, and I don't want that happening again!

Thanks
