Is there a difference between a 225mm clutch flywheel of later MY Brumby and that of L series ?

think I answered that one during latest slumber.... EA82 fly will have the three markers for no tension on valve springs for timing belt install

Different bolt spacing for flywheel to crank and flywheel to pressure plate.
Starter ring gear offset is different too.

Phiz, think the 225mm clutch pressure plate is same between the 225mmm EA81 later style flywheel and the L Series ain't it - just a smaller number of splines to suit the 4 speed MY input shaft?

I found a spacer plate ? washer from an EA82 flywheel and found its holes line up nice on the back of an EA81 crank - the clincher is the fly to crank bolts EA82 crank bolt thread is a larger size than the EA81. The flange that holds tight in the fly may be same allowing EA82 flywheel on the back of an EA81

Given the new range of motors by Fuji, this stuff is going back in time somewhat and matters to many not much anymore

I also found that the pressure plate has same bolt pattern for the 225mm flywheels whether it be MY or L.

Found visually the quick way to tell is the MY has a HUGE chamfer on the rear of the fly where the timing marks appear and the L fly is quite square. The step looks to be same too
