I am trying too figure out how to get the two speed gears off the shaft??? I know there are pins its says in the manual but I dont see anything?? I bought an entire new 2 speed complete and just want to replace it. Can anyone tell me how to take the old one off the shaft? The steps required as I do not know how. I should be more clear I mean the 2 speed off the transmission shaft. Thanks a bunch in advance!!</p>
