Whats the correct orientation of the top vent on a 915 trans when set up for use in a 914?
The bottom of the vent tube is cut on a 45 degree angle and the cut is aimed away from the ring gear at a particular angle. However, reversing the R&P changes the relative position of the angle cut to the ring gear. The vent tube must also be repositioned for it to work properly in a 914. If the angle cut orientation is wrong, gear oil will be flung into the vent tube, temporarily sealing the vent and pressurizing the gear case as it heats up, causing oil to go past the flange seals and make a mess on the outside. We had this happen in a 912E once when the customer's local mechanic had filled the trans thru the vent hole and screwed it back in all the way without regard for orientation. So the question is, which direction does the hole in the top of the vent aim in a 914? |
