Title: Dry-stored pump, salvation tactics?
Post by: Turbinepowered on September 16, 2008, 10:01:21 am

So I found a pump locally that was stored dry. As in, he drained it entirely, then stored it. 1.6TD, hadn't leaked, he broke the Jetta for parts and sold off most of them (I'm snagging a couple more just for my own nefarious purposes).

I've heard bad things about dry-stored pumps, so just wondering if there's some way I can fill it, and something I can fill it with, that will help reduce the potential damage. It was stored indoors, so it wasn't out in this horrid Southeastern humidity, which is probably a plus.

How would one go about filling a disconnected pump?

I would open it up and check to see if there has been any corrosion first.

The veins in the vein pump may stick after being dry for a while.


How long was it sitting?

Remove the "OUT" banjo bolt
  and fill it with ATF. Let it sit for
  a while and, then. try rotating it.

As I understand it the pump has been sitting dry for almost a year.

I'm planning to use it as a core for a rebuild, but I don't want to buy if it's going to be another "Monday" pump, you know?

i think you will be OK if it's just a year and been inside?
 but you never know? fill it and spin it with a drill!
watch the fluid and look for discoloration!

In the shop almost all of our pumps are stored dry. Low humidity is what really matters.

If you are worried pop off the front advance cover and have a look inside. Just watch for shims and springs and any other goodies that may pop out

Sounds like a good, low-invasive tactic the seller might let me do. Don't know if he'd like me disassembling his pump.  :wink:

Thanks for the tips, folks!

Less than a year? Don't suppose it drained 'dry'
 Turn it with fingers and if it feels grating, then raise doubts.
If it feels smooth and little springy at the 4  compression strokes, then it's worth a punt...
