Seems to me that the "bar" clamp shown in the urq20v illustration 
provides a nice amount of clearance for working with the circlip 
tool. I used an ordinary (but large) "C"-clamp which makes access a 
bit tougher. Peter, I wonder what would be the advantage of using a 
screwdriver (as you described) rather than a nice bar clamp as shown? 
Without using a clamp it might need to be a three-handed operation, 
right?  I guess if no clamp is available at all...then your 
screwdriver trick does the job.

I recall really struggling getting the circlip reinstalled. As I 
recall, my main problem was in having all those little spring-steel 
tabs ("fingers", or are they "toes"?) to lie flat enough so that 
there'd be clearance for the circlip to fit into its groove. To 
"operate" the circlip I ended up filing down the tips of a long 
long-nose pliers (used instead of my Channel-Lock snap-ring pliers, 
which couldn't reach far enough).

I did use a new 6405 rubber seal (ordered from NAPA)--same as shown 
in the illustration. Makes little sense to rebuild without replacing 
that  seal. All the other bits were OK.
