Pump rebuild complete, but still leaking



Thanks to everyone who responded about the hydraulic fluid not coming
out of the brake port while priming. It sounds like this is common, and
that that side of the pump doesn't start working until you install it
and bring it up to speed. It even took a little revving of the engine to
get the brake light to go away and the bomb to get pressurized. But then
everything worked fine, sure enough...

...except that the pump is still leaking some, at the joint between the
pump halves. Doing a quick steering lock-to-lock while parked was enough
for the fluid to start showing itself along that joint. Foolishly I
didn't check the flatness of the halves, as Mark Woodland described
recently, so maybe I'll pull it back out and check that. Or if anyone
has any other ideas, let me know. 

In general, the pump looked good inside. It really is a neat thing on
the side, when you see the pistons in their rotary arrangement and all.
The job went pretty well, though the piston caps (with their big +
heads) were awfully tough to get off. I'm not sure if I was using the
hand impact driver right, since I had no success with it, but a 15"
breaker bar worked. I found that you really need to "shape" the drag
link socket just right to get it to work well; otherwise it's all to
easy to round those heads. What an odd fastener.
