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?

Seems to be the case....strange. Im trying to think of how to verify this before pulling engine all the way out to pull the pan.

It sounds like the crank has snapped at the rear main journal.

Perhaps the crankshaft isn't broken and the bolts that hold the flywheel to the crankshaft have sheared off?
I haven't pulled engine yet, but preliminary sure looks odd, like a broken crank. The flywheel turns with starter and hydro pumps turn. I'm going to pull it and pull the pan. I will post when I find the issue
finally got back on this. pulled the pan to have a look, nothing abnormal can turn the crank with wrench on fan end, pulled inspection cover for flyweel and that looks normal. need to pull the engine.
question:
best way to pull engine to get at flywheel? should I unhook plumbing to pumps and pull them with the engine? or separate the engine from the bellhousing and leave the pumps?

Anyone have a torque chart for New Holland LX865 engine? 9/16 flywheel bolts and the 3/8 bolts attaching gear to flywheel. Also wondering what everyone is using for sealant around the bell housing to cover? This section runs full of oil for the pump gears
Was there a gasket on there or was it permatex. I would look at the parts diagram and see if NH makes a paper gasket and if so get it.
you never know bolts may been to harded to the point they were brittle, ford is having that issue with exaust valves in some engines now, I heard of a failure at 1500 miles. you know with everything on these machine being fluid powered things do not come to a quick stop as when heavy clutchs were used. so bolts getting sheared is a little puzzling.
Could be some of those good ones from China. I bought a new White tractor and at around 200 hours it sheared all the bolts off the front ring gear. Then again at around 500 same thing. This time I repaired it and had t he bolts tested at work`. They were to soft. One of the engineers did some foot work for me and got the right bolts which I then put in MACHINE AND DR ILLED THEM FOR LACING WIRE. These bolts were still in it 30 years later. Funny thing is a recall was issued several years aftr I did this for bad bolts
Make sure you look at the teeth on the gears driving the hydro pumps in there. I had an LX885 broke a tooth off one of those gears, jammed in the gears and then the crankshaft broke like you initially feared.
Black RTV sealant will be fine there.
