Gearbox seal leaked out gear oil

Difficulty Level:

Remove the spark plug. Consider any safety issues. Drain the gearbox oil.
Remove the tyne hubs by removing a 3/8 ths bolt that goes thru the hub and connects the tyne sleeve to the main shaft. Remove both sides to complete both seals. Once the tyne sleeve is off, use a cordless drill to shoot drywall screws into the seal. you may need to drill small holes first, then use two claw hammers or prying tools to pop the seals up out of the seal boss area. Clean the shaft with emery paper, and clean the bore of the tyne sleeve. With your finger, put a light coat of grease on the shaft, slip the new seal down the shaft and tap it into position. Be certain to get it inserted evenly around the outer circumference of the seal. Replace the sleeve and bolt everything back together.

Total Repair Time:

Tools:
Pliers, Screw drivers
Parts Used:

1. Removed tine
2. Removed the oil seal. (not easy at all)
3. Replaced oil seal.
4. Screwed up the first oil seal so I had to remove that one. (be careful about making sure the seal gets seated uniformly before trying to pound it in)
5. Replaced with 2nd oil seal that I purchased. (made sure I used plenty of g rease on the tine shaft and coated the oil seal and it went in so much smoother. consistent pressure will avoid my mistake.
