...Installed Gen3 gearbox...We installed the engine hoist and used cargo straps to release the strain on the engine so we could remove all the bolts connected between the engine mounting plate and the engine mount. Once they were all removed, I used a cutoff wheel to remove 2 unneeded mounting bolts left over from Gen1. We installed the tortion flywheel after removing the old flywheel. We lifted the gearbox up and slipped its slpine into the matted hub on the new flywheel after verifying with the Eggenfellner provided alignment tool that all would mate together properly.
