LTX1046 Hydrostatic rear axle oil fill won't unscrew.

Have slight gear oil leak out of rear axle. Would like to add some gear oil occasionally. Removed battery, removed tin plate. tried to remove oil plug with allen wrench......wouldn't budge. Even tried my Ryobi lipo impact driver. Didn't work either.

Is the plug reverse thread??? Does it have Loctite and must be heated to remove???

Any help would be appreciated.:smile:
