Thanks for that scan Old Magnet, I have 2 of these Bee Gee pumps apart here in Australia that need reconditioning, one off a D4 2T and one off a RD6, on both the drive shaft seal is shot, the D4 was actually pumping hydraulic oil into the D4 transmission and from there into the main clutch housing!
With the help of my Fitter and Turner neighbor Geoff we looked at the D4 pump 2 years back and thought a modern ceramic seal could in theory replace the old seal but are we correct not knowing how much pressure there is in that drive tunnel, in theory it is low pressure but can it get spikes that would blow a modern ceramic seal?
Who makes the "replacement" seal A13449, and that number V-754 is I assume the bronze sleeve in that drive tunnel?
Thanks
Mike

Pressure for the #1400 should not exceed 850 psi. You'd want to be sure you have a functioning pressure relief valve. Leakage along the shaft has been known to warp covers and thrust plates. As far as the seal replacement that's where Associated Tractor comes in. They are the only source I know that offers a replacement seal although I don't think they have anything exclusive.
