STEP 8)
Verify that S20 and S30 are now the same (or
at least within .05mm). S10 will natively match
with S30 and S20 will natively match with S40.
Depending on the shape of the spindles used, a
close value is good enough. The spindles are not
allowed to touch anywhere, however. If that were
to be the case, the spindles are severely damaged
and probably need to be replaced.
STEP 9)
While hand turning the Spindles, verify that the
shafts turn freely. Also verify, by holding a white
sheet of paper underneath the spindles and then
shining a flashlight upwards, that the gaps are
clear from galls as well.
STEP 10)
Fixate the Gear Synchronization Lock Ring (Pos.
2515) while tightening the EIGHT (8) Socket Head
Cap Screws (Pos. 2186) to 8 Nm (5.9 lb-ft.).
Now you can re-assemble the pump.
