I. TIMING OF INDIVIDUAL CORER GEAR CASE
The purpose for timing each individual Gear Case is to ensure that the tine will enter and leave
the soil at the proper angle and sequence.
There are three corer gear cases on the Fairway Aerator. The upper and lower crankshaft
flywheels for each Tine Arm must be assembled so the Offset Shafts are located in the same
"clock" position. That is, if the Upper Offset Shaft is positioned at 12 o'clock, then the Lower
Offset Shaft must be at the 12 o'clock position (View A). The upper and lower shafts for the
opposite side of the shared Gear Case will be 180 degrees apart. If the Shaft position on one
side of the Gear Box is at 12 o'clock, then the Shaft position will be at 6 o'clock for the opposite
side.
To achieve the proper "clock" position for each gear case, install Timing Bar (82-3200) to the
upper and lower crankshaft by aligning each Roll Pin and securing with Socket Hex Head Cap
Screws (View B). Timing one side of the gear case will automatically align the opposite side of
the gear case because the two sides are connected by a common shaft.
