+===== The Shifter Shaft Seal =====
 **Install On all models:**\\
 The oil seal can be removed without removing the primary cover - remove the lever, then use a pick or screwdriver to pry the seal out of the cavity.
@@ Line 38: / Line 38: @@
 On installs, make sure the shaft is free from debris or rust and 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.

 The Oil Seal is installed first, followed by the washer/spacer (the '04-'05 Parts Manual may show the **WRONG** order).\\
 NOTE: There is a [[http://sportsterpedia.com/lib/exe/fetch.php/pdf-bulletin:tsb1350.pdf|TSB (M-1350)]] related to the 'NEW' Shifter Shaft Seal P/N 11000101 being installed with Special Tool HD-51337. The new seal has a 'garter spring' to help seal the shifter shaft from leaks. In this TSB, the following caution is made: If the tool is not used, install seal to a depth of 0.125-0.135 inches. DO NOT bottom the seal in the bore. Bottoming the seal will damage it and prevent it from sealing properly. (While this bulletin refers to Big Twins with 6-spd transmissions, this shifter shaft seal is used on other models, including the Sportsters.)

+The idea is that if you bottom the seal, the lips around the shaft will be pressed tightly against the primary cover and will not allow the lips to smoothly follow the movement of the shaft. Thus, the tight lips will be thwarting the 'sealing' aspect that the 'garter spring' is designed to enhance.
-NOTE: Some owners have mistakenly gotten 2006-later covers and installed on 2004-05 engines. Neither stock shifter shaft seals would fit correctly, but purchasing an aftermarket seal, 12mm x 22mm x 5mm R23, seems to fit.((See post#15 from 93trident of the XLForum - http://xlforum.net/forums/showthread.php?t=2079676))
+The clearance should be from the deepest edge of the seal cavity in the primary cover. The referenced instructions are for the BT models. Therefore, the Sportster models may not be exactly the same.
+BUT, the principle still applies: Insert the seal slightly below that deepest edge of the cavity and don't bottom out the seal. That gives it the best chance to work correctly.
+NOTE: Be sure to match the right bushing & seal to the shifter shaft of the engine year. An aftermarket seal, 12mm x 22mm x 5mm R23, seems to fit in some cases. The R23 version has double lips compared to single lip on the R21 version. ((See post#15 from 93trident of the XLForum - https://www.xlforum.net/forum/sportster-motorcycle-forum/sportster-motorcycle-motor-engine/sportster-motorcycle-bottom-end/202496-what-s-that-about-then?t=2079676))
+Also see the Sportsterpedia Primary Cover info [[techtalk:evo:priclutch02|HERE]].
 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. (But be sure you are installing the seal correctly as mentioned above, not bottoming in the bore.)
