I have a collar to replace the output shaft snap ring to head-off failure of the stock ring. For those of you that have been down this road, mine is a 241HD version which requires removing the original ring through the plug in the top of the output housing. My concern before I get the case apart is how does one re-install the new collar through the small plug in the top of the housing? Don't you have to reassemble in reverse order which means somehow putting the collar on before the housing? Any hands on experience would sure be a great help.
