I have a 1963 Electra with a healthy oil leak at the kick start shaft. The exploded view of the gearbox in my parts manual doesn't show anything resembling an oil seal.
Any suggestions on how I stop this leak?
The square section seal from the NOC shop worked for me. The square section option is not the standard round section O-ring but works better. Fit it on the gear lever as well. You have to take care not to damage it when re-fitting the cover.
Can these O-rings be replaced without removing the gearbox?
You have to take the gearbox cover off but the gears are not affected..
