Sorry guys I forgot to post the procedure, I have it at my shop and will post it tomorrow night. I must say however that the procedure is not just for when you are converting to wood from alloys, it the Deere procedure for timing all walkers no matter the bearings you have.
Dont mean to be rude greengiant but sometimes you cant do one at a time, like when you have all the walkers out of the machine, or you have to change a crank shaft. ALSO you have to start with all the front bearings tight FIRST because the bolt holes in the front of the walkers are NOT slotted and the rears are. If the rears had no slots then you could not time them and there would be binding at several points of rotation with each walker.
Again I will post the exact timing procedure tomorrow but keep in mind that sometimes the procedure does not work so well. I have timed them when they were under constant slow rotation with all the fronts tight first then working back and forth from the outer walkers, tightening them little by little to eliminate any tight spots.
Ill elaborate more later after giving Deeres textbook procedure, which by the way is not the way they do them on the assembly line.

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).
