CAB BODY REPAIR (CONT)
2.
REQUIRED RIVET SPACING IS DETERMINED BY STRENGTH NEEDED IN JOINT. GENERAL FEEL
FOR STRENGTH REQUIRED CAN BE OBTAINED BY INSPECTING RIVET PATTERNS IN
SURROUNDING AREAS. BODY REPAIRS MADE USING SINGLE ROWS OF RIVETS SHOULD BE
PERFORMED USING RIVET SPACING NOT GREATER THAN 1-1/2 IN. (4 cm), AND NOT LESS
THAN 5/8 IN. (16 mm). USE 1 IN. RIVET SPACING AS GENERAL PRACTICE FOR REPAIRS. RIVET
SPACING USED IN ORIGINAL CONSTRUCTION MAY BE GREATER DUE TO ADDITIONAL
STRENGTH OBTAINED BY USING FOAM ADHESIVE TAPE. DO NOT USE RIVET EDGE
DISTANCES LESS THAN 3/8 IN. (5 mm).
3.
HIGH-STRENGTH JOINTS OR LARGE AREA PATCHES MAY REQUIRE USE OF DOUBLE OR
MULTIPLE ROWS OF RIVETS TO OBTAIN SUFFICIENT STRENGTH.

Be careful not to distort original holes to prevent damage to equipment.
4.
CARE MUST BE TAKEN TO ASSURE RIVET HOLE PATTERNS ARE TRANSFERRED ACCURATELY
IN CASE WHERE PART WITH NO HOLES IS MATED TO ONE WHICH ALREADY HAS RIVET
HOLES. HOLE PATTERNS MAY BE TRANSFERRED USING ONE OF FOLLOWING:
LAY NEW PART IN PLACE AND USE HOLES IN MATING PART AS DRILL TEMPLATE. NEW
PART MUST BE UNDERNEATH MATING PART.
USE REMOVED PART AS DRILL TEMPLATE BY CLAMPING OLD AND NEW PARTS
TOGETHER. PARTS MUST NEST FLAT AND RIVET FLANGE MUST BE UNDISTORTED.
