TINE REEL REMOVAL AND TINE ROW REPLACEMENT (see parts illustration on page 11)

TINE REEL REMOVAL

NOTE: Tine reel removal is only necessary to replace an entire tine row or for other major unit maintenance. Individual tines can be replaced by following the INDIVIDUAL TINE REPLACEMENT instructions.

1.With the tines in a raised position, secure the unit by chocking the wheels.

2.Remove the four bolts and nuts, two on each side, holding the tine reel bearings in place. BE CAREFUL the tine reel is heavy and sharp. Take precautions to not allow it to fall when the bearing bolts are removed.

3.Lift the reel up and to the side to remove it from the drive chain.

4.See TINE ROW REPLACEMENT for instructions on maintenance.

5.To reinstall the reel follow the above steps in reverse.

TINE ROW REPLACEMENT

1.Remove the tine reel per the TINE REEL REMOVAL instructions.

2.Remove the cotter pin and nut at the end of the tine reel shaft that secures the tine rows in place.

3.Remove the tine rows and spacers as necessary to replace the defective part. Be sure to note the order in which the spacers were removed for later reassembly.

4.Reassemble the tine reel in the exact order that it was disassembled.

5.Tighten the nut that secures the tine rows and spacers on the shaft. Torque the nut to a minimum of 100 ft.lbs. Check that all of the tine rows are tight by attempting to move them by hand.

6.Reinstall the tine reel per the TINE REEL REMOVAL instructions above.

TIP: Spraying tines with a rust preventing lubricant can increase tine life and allow for easier replacement of worn or damaged tines.

INDIVIDUAL TINES REPLACEMENT

1.With the tines in a raised position, secure the unit by chocking the wheels.

2.Loosen but do not remove the outermost nut and carriage bolt that secure the damaged or worn tine.

3.Loosen and remove the innermost nut and carriage bolt that hold the tine in the reel.

4.Use a small pry bar and push the tine plates apart slightly to slide out the tine to be replaced.

5.Slide the new tine in place and secure with the innermost nut and carriage bolt. Tighten completely.

6.Retighten the outermost nut and carriage bolt to completely secure the new tine.

7.Repeat as required to replace all damaged or worn tines.

NOTE: Tines are a normal wear item and should be inspected regularly for signs of wear or damage.

LUBRICATION

BEARINGS-

1.With the tines in a raised position, secure the unit by chocking the wheels.

2.Lubricate all the bearings using a pressurized grease gun with standard lithium based grease.

3.Wipe any excess grease off of all bearings and fittings after each lubrication.

NOTE: If machine is cleaned with a pressure washer, the bearings should be lubricated after each cleaning.
