Ford Model A - Sealing the transmission shaft (gear box)

The transmission can be the cause of an oil leak. Therefore I have modified this part of the gear box.

In the lower part of the picture you can see the two gear shafts.

Here you can see the modified gear shaft on the left hand side with an O-ring. On the left is the old original one. You don't have to make this modification by yourself, you can buy it at Bratton's. Source:  http://www.maurer-markus.ch/ford_a/mod_getriebewelle.en.html
