| + | Below are pics of the shift drum with the fork and fork pin positions for each gear. \\ | ||
| + | You can see at what point along the channel in the shift drum that the forks and their corresponding pins rest per gear select. \\ | ||
| + | With the tranny on the bench, if you notice a lot of movement in a fork, the pin never comes out of it's corresponding channel. \\ | ||
| + | The entire transmission has a certain amount of slop on it's own (on the bench). \\ | ||
| + | But one reason for noticeable slack/ | ||
| + | If the fork is moving, it's traveling along the drum's channel (left to right). \\ | ||
| + | And all 3 forks have enough designed slack in them to act somewhat independant of each other even though they are all key to the drum. \\ | ||
| + | Another reason could be wobbled out holes in the forks where the pins install. \\ | ||
| + | Another reason could be a worn oil boss in the bottom of the channel or simply a worn out channel itself. \\ | ||
| + | The pin being in a straight portion of the channel keeps down side to side movement. \\ | ||
| + | But the pins were not deigned to have a rigid seating and will still allow some fork movement. \\ | ||
| + | And always remember the entire tranny will have flex all around it if it's not affixed on both ends. \\ | ||
