| * The shifter shaft extends out through the primary cover. The foot shift lever is attached onto the shaft splines at the end. The shifter pawl is attached to the shifter shaft allowing the pawl to pull or push the rotating transmission shifter drum into gear as the shifter shaft rotates. In the detailed picture of the pawl, the shifter detent plate has been removed to show the pawl and the end of the shifter drum with it's four protruding pins. | * The shifter shaft extends out through the primary cover.

| * Be sure to carefully adjust the shifter pawl as outlined in the factory service manual. This procedure is critical to center it's travel of movement to create accurate gear shifts. You must use a #32 drill bit for accuracy - no other size works properly.

| - | * The shifter drum pins are an issue. Due to the engine heat cycles and the constant push and pull by the shifter pawl, the drum pins tend to come out (somewhat) from their mounting holes, causing the detent plate to skew from perpendicular. This causes stress on the detent plate retaining clip and causes excessive wear on the detent plate due to the skew. Whenever the shifter assembly is accessible, these pins should be homed into the shifter drum with a __minimal__ tap on them with a hammer & punch.((http://xlforum.net/forums/showthread.php?t=1675146)) | + | * The shifter drum pins are an issue.

((HD Tech Tip #47 dated March 1998)) If you find the pin height outside this range, replace the pins or the shift drum as necessary. |

| - | On installs, be sure to put tape over the splines on the shifter shaft before installing the oil seal to prevent the splines from cutting the seal. | + | To increase the tightness of the oil seal (as often suggested by SportsterPaul), after installing the rubber washer, you might install one or two o-rings to take up the gap between the shift lever and the washer. The o-rings do not seal against leaking oil but, instead, they put additional pressure on the oil seal in the primary cover cavity, which does help to seal against leaks.

| * Another idea to install the detent plate, is to thread the end of the shaft, then use a nut with blue Loctite.
