LX865 skid loader was at idle and engine died. When I attempted a restart, the starter spins fast and doesn't sound like it engages engine..... as if a bendix isn't kicking into flywheel, but i was able to raise the boom using the starter. Looking at parts diagram I don't see how the hydro pump would turn with the starter and not the flywheel. Maybe a hard failure of something? Where should I start troubleshooting?
