 I'm now offering this speedo drive gear modification to help seal one of the more persistent leaks on the 914 transmission. By adding a second, lower o-ring to this part it not only gains a second barrier again leaking, but also helps reduce the vibration that can wear the clearances and cause further leaking. This part sits inside the transmission tail cone and the angle drive screws into it, then the cable attaches to the angle drive.  The new internal seal is noticeably smaller on the ID. This means more sealing pressure against the gear shaft, and therefore better sealing against oil leaks.  Now available HERE from 914Rubber. This member (Thanks Eric!) had a significant leak at the speedometer, even while parked. After this modification was done... ZERO LEAKS! Read his story here. |
