I drew a blue circle on the hole / port on the transmission case picture. It will not help to get a picture of the front because the hole is on the back. I spoke with a ZF rebuilder today
He told me that inside the hole is a 10×70 socket head cap screw. As I suspected.
There is only a few inches between the transmission and the frame at this location. I spent a couple hours today trying to pull out what seems to be a plug of silicone. The silicone is blocking the bolt. Seems the transmission has been out before. I am worried the bolt is loose and would like to check it. But I have about given up . The clearance between the frame and hole is only 3.5 to 4 inches. I might give it one more try.
The hole is about 10" to the right of the output saft and about level with the top of the output shaft.
Any ideas on getting the silicone out of the 3" deep 5/8 diameter hole?
I might remove the left steer cylinder on this terex Ta 30-7 to improve may access.
Thanks

Hi again Philip,
as far as I remember these bolts are supposed to fix the internal suction chamber.
Leakage from there is either a loose or lost or broken bolt. As long as there is no excessive noise from pump when warm I'd just try to tighten bolt, allen head. And try to seal with silicon or similar.
Some pump noise when cold and higher rpm is normal.
