Hey Guys, I have been working on the trans in my 35 Master. After changing the universal joint, you need to add gear oil to the torque ball. On my trans, the filler hole for the torque ball also doubles as the negative battery cable ground. Anyways, the hole is small and when trying to fill with gear oil, it is very challenging due to air locks. Consequently, you can easily make a mess.
I was at our local Tractor Supply store and saw a large 2 oz syringe (used for large animals). It ends up working perfectly for filling the torque ball with the recommended 8 oz of gear oil.
Here is a picture, hope this is helpful to anyone needing to put oil in their torque ball. :)
