Check grapple tine tips for wear and replace as needed, following the procedure below. Do not al-
low tips to wear down to the parent material.
Build-up and hard-surfacing of grapple jaws is optional to prevent excessive wear. Depending on
the application, it may or may not be necessary. Use your discretion to determine whether it is
warranted by the severity of the application.
Tip Replacement Procedure
Follow all welding safety precautions found in this manual.
Preheat the area to 350º F (177º C), six to eight inches around the tip. Maintain this temperature
throughout the procedure. Do not exceed 400º F (204º C) interpass temperature.
Air arc to remove the tip. Clean the pocket and chamfer the perimeter at 5/8” x 45º angles.
Position and tack the new tip in place.
Weld with AWS E7018 electrode. Begin with the sides, filling in the chamfered area with single
passes, alternating sides and peening each pass. Weld the back and front following the same
method.
When welding is complete, grind the welds flush on each side.
Cover with heat blanket or insulation and allow to cool slowly.
DO NOT put unit into operation until cool, approximately eight hours.
