HI, I need to replace the axle seals on a Iseki TXG23. In the manual it looks like an outer and inner 'snap-clips' are used to hold the axle in. Does anyone know if this is correct or are there another fixing inside the gear/differential lock assembly that are holds the axles in. I have tried to take off the seal and outer clip to remove the axles. They will not budge this far and before i put more pressure on the shaft I thought it best to ask. Anyone completed a seal replacement on these little tractors?
