(But be sure you are installing the seal correctly as mentioned above, not bottoming in the bore.Welcome to our website. 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 may help if you have a leaking 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. That gives it the best chance to work correctly. Therefore, the Sportster models may not be exactly the same.īUT, the principle still applies: Insert the seal slightly below that deepest edge of the cavity and don't bottom out the seal. The referenced instructions are for the BT models. The clearance should be from the deepest edge of the seal cavity in the primary cover. Thus, the tight lips will be thwarting the 'sealing' aspect that the 'garter spring' is designed to enhance. 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. (While this TSB refers to Big Twins with 6-spd transmissions, this shifter shaft seal is used on other models, including the Sportsters.) Bottoming the seal will damage it and prevent it from sealing properly. This allows the spring to keep the lips of the seal against the shaft. 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. The new seal has a 'garter spring' to help seal the shifter shaft from leaks. NOTE: There is a TSB (M-1350) related to the 'NEW' Shifter Shaft Seal P/N 11000101 being installed with Special Tool HD-51337. The Oil Seal is installed first, followed by the washer/spacer.įor 1986-2005, the new shifter shaft oil seal is P/N 11000101. 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 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.
