This is Deeres textbook procedure however Like I said before its not what they use during assembly line production.
Timing of the straw walkers is performed as follows:
NOTE: When bearings or crankshafts are serviced
re-timing is required. If not timed correctly, straw
walkers will fail in a very short time.
1. Disconnect the straw walker drive belt.
2. Tighten hardware on the front bearings to the
recommended torque of 45 N·m (33 lb-ft).
3. Tighten the nuts on all the rear bearings and then
back them off slightly.
4. For each rear bearing, rotate the crank one full
revolution until the throw of the crank is at its bottom
most position. Tighten the bearing.
5. Tighten the bearings in the following sequence:
• Outside Left
• Outside Right
• Inside Left
• Inside Right
• Center (if applicable, on 9600)
6. If a tight area is noted during the revolution of the
crank, loosen and re-tighten the previously set bearing.
7. With all hardware tight, rotate walkers by hand and
check for any resistance.
8. If any resistance is detected, repeat the complete
timing procedure.
9. Walkers should rotate freely.
10. Torque all hardware to 45 N·m (33 lb-ft).
