[Vwdiesel] Injection Pump talk ---- ( testing pump for wear )

[SLATERSFB at aol.com]

Water will not pass into pump through check valves unless these have totally 
turned to rust. Good idea to disassemble each one & check. If you find rust, 
probably a good idea to go deeper into pump. Rust on springs or any bearing 
surface will lead to failure; find out now or on the side of the road later. 
Really nice inside & worth a look any ways.

It has seen some weather (sprocket rusty) and had injector lines 
disconnected from pump, and engine standing on end with unions facing up. It 
turns 
freely, and I sprayed some WD-40 into all fuel openings to dispel any water. 
I will put 
it on the bench and test with a dial indicator to see how it looks. Anything 
else I can 
do short of pulling it apart to check for corrosion?
