Go to this website and type in PONY for your model number and find your operator manual by your serial number. The operator manual should have detailed instructions on how to replace your seals.
On the Horse model you remove the wheels and then carefully use a couple of screw drivers to pry out the old seals being careful not to scratch the wheel shaft sealing area. Then polish the wheel shaft with fine emery cloth to remove any sharp edges. Then grease the wheel shafts and carefully slide the new wheel seals on and use a piece of plastic PVC pipe cut square that will slide over the shaft and gently drive the seal to the depth the old seals were installed at. You dont even have to drain the gear oil. Getting the wheels off the wheel shaft is sometimes a problem if they are rusted on. if you can get the wheels off its not to hard to change the seals.
