New Holland 634 round baler gear box removal.

[sk252]

Trying to remove gearbox on new holland 634. All bolts are loose but it won't come off the output shaft. Do the chains need loosened on outside of the output shaft? It looks like the shaft should come off the box but it's a no go. Just wondering if I'm missing something. Any help would be greatly appreciated.

Seems to me there is a coupler with grease fittings between the gear box and bearing/chains, is it stuck? Never had gearbox out of our 630, but grease the output shaft.

Take the chains off the drive sprockets and remove the bolts from the bearing flanges on the outboard bearing. The shaft with the sprockets and coupler will slide off the gearbox output shaft with persuasion.
