No problem, testers are $30 shipped to buy and to rent it's just the cost of shipping both ways, which is about 11 dollars!
To replace the seals, stator side, remove the flywheel-duh, stator assembly, What i use is a drywall screw with a piece of tape about 3/16" up from the point so i don't go in to far and mess up the bearing. I use a dental pick (real sharp) tap it with a hammer a few times until it peirces a hole in the seal body, then i screw the drywall screw in up to the tapeuse a pair of channel lock and pull that muther out! wipe out the case where it sat with papertowel, put a little white lithium grease on the inner seal lip(that goes around the crank shaft) and gently tap it in evenly till it's flush with the case i made a seal installer out of a piece of 2x4 drilled a 1.5" hole out of it to fit over the crank shaft and just rotate it 90 degrees after every tap. the clutch side uses the same method of removal and install, but you have to remove the clutch basket and the gear on the crank shaft. there is a pic on here some where i'll see if i can find it!
