Removing and installing a crank oil seal had been around for years and methods and tools has been evolving. I would like to share my new oil seal removal tool innovation that I haven't seen similar on the market and the best tool that every home small engine mechanics wish to have. For only $2 and any heavy scrap thick metal tubing as a hammer, you can make one of this. My YouTube video will show you how to make one which is quite easy but no one thought about it.
