Hi,
Maybe worth a read, the A10 is similar to the A65:

You usually find that the oil seal has a couple of centre pots around it to help hold it in place. I usually find that a large screw driver will hook them out. Tap the new one in. If you have a large diameter piece of tube so much the better for knocking it in.
Check the wear of the spacer which the seal runs on. It should be fine but a bit of metal polish won't go a miss, any deterioration to it whether it be pitting or bits of stuck rubber will destroy the new seal.
