I did replace my DMF at around 411k miles because it was outside the wear limits. Luckily I had a very good used DMF from a scrapper I bought for the bonnet.
Another point with the M47R is that, unlike its M47 sister engine, it has a cast crank instead of a drop forged one. Now there is nothing wrong with cast cranks generally, but there have been a few reports of broken cranks on the M47R, and a solid flywheel will put more strain on the crankshaft.
So for that reason, and for the most refined ride for a stone crusher I'd stick with having a DMF, but each to their own.
