SECTION A-A

1. APPLICABLE STATNDARDS/SPECIFICATIONS:

A. ASME Y14.100-2004

B. ASME Y14.5M-1994

1.1 APPLY PAINT COATING SYSTEM USING TT-C-490 TYPE I or TYPE II PRETREATMENT, MIL-DTL-53084 or MIL-DTL-53022 TYPE IV PRIMER, AND MIL-DTL-53039, MIL-DTL-64159, OR MIL-PRF-32348 TYPE III TOPCOAT IAW MIL-DTL-53072. TOPCOAT WHEEL WITH COLOR CHIP NUMBER 37030 LUSTERLESS BLACK IAW FED-STD-595.

DO NOT APPLY CARC TOPCOAT PAINT TO BEAD SEAT OF RIM OR PORTIONS ENCLOSED BY TIRE OR AREA THE VALVE STEM CONTACTS THE WHEEL ON THE SURFACE OUTSIDE THE TIRE CAVITY. PAINT COATING SYSTEM THICKNESS SHALL NOT EXCEED 3.5 MILS IN THE WHEEL MATING SURFACE TO HUB (AND OPPOSITE SIDE).

COATING THICKNESS SHALL BE MEASURED AT A MININUM OF FIVE LOCATIONS ON EACH OF THE WHEEL MATING SURFACE TO HUB LOCATIONS (AND OPPOSITE SIDE) BETWEEN BOLT HOLES. EACH LOCATION MEASUREMENT TO BE MEASURED 3 TIMES IN A 1.5'' CIRCLE BETWEEN BOLT HOLES USING THE AVERAGE OF THE 3 READINGS.

2. INSTRUCTIONS FOR ASSEMBLY- HAND MOUNTING:

A. TOOLS REQUIRED:

1 RIM MALLET

1 SELF LOCKING PLIERS

1 SWAN NECKED BEAD TOOL

2 TUBELESS TIRE TOOLS

LUBRICANT

B. MOUNTING (BY HAND)

(1) INSPECT THE TIRE AND RIM FOR ANY DAMAGE. BE SURE TIRE SIZE AND RIM SIZE

MATCH EXACTLY. IF THERE IS ANY RUST OR SCALE ON RIM SURFACES, REMOVE

WITH WIRE BRUSH OR MEDIUM GRIT SAND PAPER FOR SMOOTH FINISH.

(2) INSERT VALVE STEM. PUT VALVE STEM WITH RUBBER GROMMET THROUGH VALVE

HOLE. FROM OPPOSITE SIDE (WEATHER SIDE). SCREW ON VALVE HOLE WASHER AND NUT. FINISH

TIGHTENING WITH WRENCH TORQUE TO 106-133 LB-IN. DO NOT OVER TIGHTEN.

(3) PLACE RIM ON FLOOR WITH RIM SHORT SIDE UP, WITH AN APPROVED TIRE

LUBRICANT, USING A BRUSH OR SWAB, LUBRICATE BOTH BEAD SEATS OF THE RIM

AND BOTH TIRE BEADS.

(4) LAY TIRE ON THE RIM. IF THERE IS A BALANCE MARK (YELLOW DOT) INDICATED ON

A LIGHT SPOT ON THE TIRE LINE THIS MARK UP WITH THE TIRE VALVE STEM. IF THERE

IS A MARK (RED DOT) ON THE TIRE INDICATING THE HEIGHT SPOT OF THE TIRE

RUN OUT, LINE THIS UP WITH THE DIMPLE IN THE WHEEL IF IT IS MARKED. IF NOT,

LINE IT UP WITH THE VALVE STEM. PUSH LOWER BEAD OVER FLANGE AND INTO RIM

WELL USING STRAIGHT END OF THE TOOL WITH STOP RESTING ON RIM FLANGE. REPEAT

PROGRESSIVELY AROUND THE TIRE WORKING WITH SMALL SECTIONS UNTIL THE TIRE

IS COMPLETELY OVER THE RIM.

(5) STAND ON THE TIRE TO START UPPER BEAD OVER THE FLANGE INTO WELL IN RIM. WHEN

NECESSARY, PUT SECTION OF BEAD INTO RIM WELL AND ANCHOR WITH SELF-LOCKING

PLIERS. PINCH PLIERS ONTO RIM FLANGE, SNUB SIDE TOWARD TIRE USING SPOON

END OF TIRE TOOL. WITH STOP TOWARD RIM, WORK PROGRESSIVELY AROUND BEAD. REPEAT

TAKING SMALL SECTIONS AROUND TIRE UNTIL BEAD SLIPS OVER FLANGE ONTO RIM.

IF NECESSARY, INSERT SECOND TIRE IRON AND AGAIN LUBRICATE LAST 8 INCHES OF

BEAD BEFORE COMPLETING PROCEDURE.

CRITICAL SAFETY ITEMS CONTAINED IN NOTE 2.B.6

(6) INFLATE THE TIRE TO NO MORE THAN 5 PSI TO POSITION THE TIRE BEADS ON

FLANGES. TO COMPLETE THE SEATING OF THE BEADS, PLACE THE TIRE ASSEMBLY IN

A SAFETY CAGE OR OTHER OSHA APPROVED SAFETY DEVICE USING AN

EXTENSION HOSE WITH AIR GAGE AND CLIP ON AIR CHUCK, STAND CLEAR OF THE ASSEMBLY

AND INFLATE TO 20 PSI. CHECK THE ASSEMBLY CAREFULLY FOR ANY SIGNS OF

DISTORTION OR TIRE IRREGULARITIES. IF DETECTED, SCRAP THE TIRE. CHECK

TO SEE THAT THE TIRE BEADS ARE PROPERLY SEATED. INFLATE TO 100 3 PSI,

BEFORE REMOVING FROM SAFETY CAGE OR RESTRAINING DEVICE- CHECK TO SEE

THAT THE TIRE BEADS ARE PROPERLY SEATED.

C. MACHINE MOUNTING:

THERE IS A VARIETY OF THE CHANGING MACHINES FOR LARGE TRUCK TIRE/WHEELS. THE

FOLLOWING INFORMATION IS GENERAL INSTRUCTIONS FOR DEMOUNTING AND MOUNTING TIRE BY MACHINE. YOU WILL HAVE TO GET PROPER INSTRUCTIONS FOR THE MACHINE THAT YOU ARE USING.

BE SURE TO CONSULT THE MANUAL FOR THE MACHINE YOU HAVE.

(1) INSPECT THE TIRE AND RIM FOR ANY DAMAGE. BE SURE TIRE AND RIM SIZE MATCH

EXACTLY. IF THERE IS ANY RUST OR SCALE ON RIM SURFACES, REMOVE WITH WIRE BRUSH

OR MEDIUM GRIT SAND PAPER FOR SMOOTH FINISH.

(2) INSERT VALVE STEM. PUT VALVE STEM WITH RUBBER GROMMET THROUGH VALVE

HOLE. FROM OPPOSITE SIDE (WEATHER SIDE). SCREW ON VALVE HOLE WASHER AND NUT. FINISH

TIGHTENING WITH WRENCH, TORQUE TO 106-133 LB-IN. DO NOT OVER TIGHTEN.

(3) PUT WHEEL ON MACHINE, SHORT SIDE OF THE RIM OUT. LOCK THE WHEEL TO THE MACHINE, LUBRICATE WHEEL AND TIRE BEAD, PUT THE TIRE ON THE WHEEL, PUSHING THE BEAD OVER

THE FLANGE AS FAR AS POSSIBLE.

(4) INSERT ROTATING ARM IN CENTRAL HOLE. INSERT THE DISC OF THE MOUNTING TOOL

BETWEEN THE BEAD AND THE RIM FLANGE. ROTATE THE ARM BUTTON TO MOUNT THE TIRE

OVER THE FLANGE LEANING ON THE TIRE TO HELP BUTTON THE BEAD BENEATH THE FLANGE.

(5) IF YOUR MACHINE DOES NOT MOUNT BOTH BEADS AT ONCE, START SECOND BEAD INTO

THE WELL. INSERT TOOL AND ROTATE MACHINE TO MOUNT BEAD IN THE SAME WAY YOU

MOUNTED THE FIRST BEAD.

(6) FOR INFLATION PROCEDURE, SEE NOTE 2.B.6 UNDER MOUNTING BY HAND INSTRUCTIONS.

3. INFLATE TO 100 3 PSI.

4. APPROXIMATE SHIPPING DATE:

DIAMETER: 38.0 IN

WIDTH: 10.9 IN

WEIGHT: 160.0 LB

5. CONTROL METHODS FOR CRITICAL CHARACTERISTICS:

A. CONTROL METHODS:

(1) ONE HUNDRED PERCENT (100%) INSPECTION OR TEST OF THE CRITICAL OR MAJOR

CHARACTERISTIC(S).

(2) AN ALTERNATIVE CONTROL METHOD APPROVED BY THE PROCURING CONTRACTING

OFFICER'S REPRESENTATIVE SUCH AS: DESIGN OF EXPERIMENT (DOE) OR PROCESS

CAPABILITY STUDY (PCS).

B. COMPLETE PERFORMANCE VERIFICATION OF NOTED REQUIREMENTS. SEE NOTE 2.B.6.

C. MATERIAL/ FINISH CERTIFICATION.

D. COMPLETE VERIFICATION OF ALL NOTES, INCLUDING TITLE BLOCK AND IDENTIFICATION

INFORMATION.

E. CRITICAL SAFETY CHARACTERISTICS ARE INDICATED WITH THE SYMBOL.
