John Deere 318 - Manual (Page 114)

NOTE: Early models have FLAT thrust washers. Later
models have TABBED thrust washers. All service
or replacement thrust washers will have the tabs.
IMPORTANT: It is recommended to replace the early
model (flat) thrust washers with the
later model (tabbed) thrust washers.
The early model washers may spin with
their respective shafts, causing wear to
the cover bearing surfaces.

gear with tab (A) pointing up so it will be between the
two cover reinforcement ribs that correspond to the same
case reinforcement ribs.
21. Put other small tabbed thrust washer on intermediate
shaft gear with tab (B) pointing up so it will be between
the two cover reinforcement ribs that correspond to the
same case reinforcement ribs.
22. Put large tabbed thrust washer on output shaft with
tab (C) pointing up so it will be between the two cover
reinforcement ribs that correspond to the same case
reinforcement ribs.
