My industrial parts catalogue shows 6 different flywheel assembly numbers. A flywheel assembly is the flywheel and ring-gear. Three are pictured and all heavier than the automotive and substantially thicker.

512330-0560 - PV type for generators
894135-2140 - PA type for farm tractors (MT7300)
894131-0620 - TPA type for hydraulic excavator
512330-2190 - P04-05 type for hitachi UH053 excavators
894129-7160 - PY1 for hydraulic excavator
894406-7540 - PTH/PH for hitachi ex120 and ex100 excavators.

Cheers.

Some things too keep in mind are the ring gear count and different flywheel housings which are listed with the different flywheels.

Also, why heavier?
