Turn the Spindles with your hands (use gloves)
and inspect that the spindles turn freely and do

condition.
STEP 8)
Hold a white sheet of paper underneath the
spindles and verify that the spindles do not touch.

one of the shafts, and the gearwheel slipped. For
more information, please see Subsection 4.5.8
"Proper Gapping of the Pump" on page 68.
