Discard snap ring (4). Keep spring for reuse.

NOTE: If meter drive units have been timed for
staggered drop on twin row spaced planters, do
not remove drive chain from sprocket without
first noting which sprocket tooth is up. Check
that sprocket is timed with same tooth up when
chain is reinstalled or re-time meters when fin­ished according to the instructions in operator’s
manual.
