I just changed motors a few weeks ago. Now on what was a dry transmission for months is leaking out the front seal like crazy. I had fixed the leaking output seals and speedo seal.
Could a plugged transmission vent cause it the seal to blow out? I drove it around on the old motor maybe only 15 miles. On the new motor it started leaking fairly quick. I was winding it out to about 6000-7000 rpm, will that cause more pressure in the transmission case? I pulled the vent and could not see much in it. I cleaned it out with brake cleaner, should there be valve or something in it? Or is it more likely the input shaft moved around enough mating back to the clutch that the decades old seal gave out? |

Also, To run a 915, you have to flip the ring and pinion gear to the other side. So the vent is on the wrong side, and the spinning ring gear will push gear oil out the vent.
You have to move it diagonally to the other side of the case. Redrill the hole, and plug the original. |
