Introduction

This Special Instruction provides the instructions that are required in order to install the mounting brackets inside the cab for the above specified Wheel Loaders.

The mounting brackets are to be adhesively bonded to specific surfaces of the cab structure. LORD 606/6GB Acrylic Adhesive is to be used. This Special Instruction will provide guidelines on:

• Proper usage of the adhesive - applying, curing, cleanup, mount bracket removal, shelf life and storage.

• Allowed weight of the equipment to be attached to mount brackets mounted in the cab. The need to drill or weld on the cab structure should be eliminated.

This hardware kit was developed to avoid the likelihood of de-certification of the operator protective structure such as the ROPS, FOPS, or related components.

Any modifications to the operator protective structures such as welding, cutting, or addition of attachments, can change the metallurgy or structural strength. Such changes can reduce the effectiveness of the structures and must be avoided. Depending upon the specific design, some modifications or repairs may be permitted upon authorization from the manufacturer.

Examples of changes that may adversely affect the structural certification are:

• Drilled holes in the ROPS, FOPS, seat mounting, or seat.

• Welding on the ROPS, FOPS, seat mounting, or seat.

• Using existing cab bosses to mount objects that are heavier than allowed by manufacturer specifications.

• Using of the cab mounts that were not tested or certified by manufacturer.

• Use of attachments that exceed the machine certification weight.

• Use of a seat or seat belt other than listed as standard or optional for that machine from the original manufacturer.

• Installing monitoring screens etc., that invades the operator safe zone.

• Any dents or deformation of the ROPS, or FOPS structure.

• Excessive rust of the ROPS, or FOPS structure.

• Heat exposure and/or grinding on the ROPS, or FOPS structure.

Note: Failure to receive advanced approval from the manufacturer for any or all of the above items may result in the voiding of the operator protective structure certification.

Personal Protection In Adhesive Handling

Introduction

Before using LORD 606\6GB acrylic adhesive, refer to the material safety data sheet (MSDS) and label for safe use and handling instructions. This adhesive is for industrial and commercial use only. The adhesive must only be applied by trained personnel. The adhesive is not to be used in household applications. The adhesive not for consumer use.

Engineering Controls

Sufficient ventilation in pattern and volume should be provided in order to maintain air contaminant levels below recommended exposure limits. Sufficient ventilation (using explosion-proof equipment) should be provided to prevent flammable vapor/air mixtures from accumulating.

Respiratory Protection

The adhesive contains a small amount of dimethylaniline (DMA) which has poor odor warning properties. If the exposure limit for DMA is exceeded, an air-supplied respirator is recommended. Otherwise, a NIOSH approved properly fitted organic vapor, air purifying respirator is recommended. For emergency situations, confined space use, or other conditions where exposure limits may be greatly exceeded, use an approved air-supplied respirator. Observe OSHA regulations (29CFR 1910.134) for respirator use.

Skin Protection

Use neoprene, nitrile, or rubber gloves in order to prevent skin contact.

Eye Protection

Use safety eye protection that includes safety glasses with side shields and chemical goggles where splashing may occur.

Other Protective Equipment

Use disposable or impervious clothing if work clothing contamination is likely. Remove and wash contaminated clothing before reuse.

Hygienic Practices

Wash hands before eating, smoking, or using toilet facility. Food or beverages should not be consumed anywhere this product is handled or stored. Wash thoroughly after handling.

Allowed Zones Inside Cab for Brackets and Bolted on Hardware

The allowed zones for brackets and bolted-on hardware were evaluated based on following criteria:

• Locations that are within the reach of operator

• Maintaining clear evacuation passageways

• Safety of the operator in the case of machine rollover

• Visibility to the field and cab controls

• Safety of the operator protective structure

• Availability of space inside cab

The space claim for bolted-on hardware should clear the ROPS structural components called headers by 75 mm (3 inch) or more to prevent possible interference and to stay out of high-strain areas during a rollover condition. Refer to Illustrations 7, 8, 9, 10, 13, 16, 19, 22 and 24 for location of headers and bracket mounting locations designated in yellow.

The space claim for bolted-on hardware should clear the windows glass by 25 mm (1 inch) or more to prevent possible interference.

Considering the safety of operator, the bolted-on hardware should not have any sharp edges. Edges that are not rounded should not be oriented toward the operator.

Guidelines For The Use of Lord 606 Adhesive with 6GB Accelerator

LORD 606 acrylic adhesive when mixed with LORD 6GB accelerator creates a fast setting adhesive that will bond metal, composites, fiber reinforced plastic and similar materials to a metal surface creating an exceptionally strong bond with excellent surface cure and minimal surface preparation.

LORD 606 acrylic adhesive when mixed with 6GB accelerator allows precise control of the adhesive bondline thickness due to the content of glass beads.

If the acrylic adhesive is stored at cooler temperatures, allow the adhesive cartridges to return to room temperature before using. Clean mounting surfaces with isopropyl alcohol. Surfaces should be free of grease, dirt and other contaminants. Mix the LORD 606 with the 6GB accelerator. Handheld cartridges will automatically dispense the correct volumetric ration of each component. Even color distribution visually indicates a thorough mix. Once mixed, the adhesive cures rapidly.

Application Procedure of Lord 606 Adhesive with 6GB Accelerator

4. Attach mixing tip (9) and expel a mixers length of adhesive onto the testing board in order to ensure that the material mixes properly. The dispensed material is to be discarded.

5. Bracket (1) and bracket (4) are painted with E-coat that may be in direct contact with the adhesive. The bonding surfaces of cab structure and mounting brackets do not require any scuffing before applying adhesive.

6. The cab structure should be cleaned with a cleaner such as isopropyl alcohol. If the mounting bracket is to be applied to a structure component that is E-coated, such as a ROPS post, just clean the post. No additional surface preparation is needed. Ensure that the solvent has completely flashed from the surface before applying the adhesive. Do not clean surfaces with soapy water or other household type cleaners as these types of cleaners can leave a residue on the surface that can negatively impact the adhesion.

7. Protect threaded holes from adhesive penetration by plugging the holes with a plug or bolt.

8. Mounting brackets are to be located in such a way that the whole area of a mounting bracket adheres to the mounting surface of the ROPS structure with no overhang. Make marks on ROPS structure in order to designate the final location of mounting brackets.

9. Provide a dry fit-up at the marked location for the bracket and clamps (A). Adjust the elevation of the spindle on the clamp in order to account for 0.5 mm (0.02 inch) of adhesive layer. Remove clamps (A) after the fit-up.

10. Apply adhesive to substrate and mate the parts within the working time of the adhesive. A 5 to 6 mm (0.2 to 0.24 inch) bead every 3.5 to 4 cm (1.38 to 1.57 inch) should be adequate for complete coverage of the mounting bracket surface. Refer to Illustration 31 and Illustration 32 The adhesive contains small glass beads that limit how close the mount bracket can be pushed on to the structure for the ideal distance.

11. Make sure that there is enough adhesive that the whole contact area is covered with adhesive. The excess adhesive should come out through the sides during positioning of the mounting brackets and the clamping process.

12. The mounting bracket should be placed in the final mounting position immediately after applying the adhesive. The curing of the adhesive begins immediately. Follow the marks on the ROPS structure in order to locate the mounting position of the bracket. After placing the bracket with adhesive onto the structure, do not remove or reinstall the mounting bracket. Removing or reinstalling the mounting bracket can trap air pockets in the bond area that can inhibit the curing process of the adhesive. Repositioning of the bracket can be done by sliding the mounting bracket into place as long as the repositioning is done within the open time of the adhesive.

13. Secure mounting bracket in place in the required position with the use of masking tape. Pieces of the tape should be attached to the upper boss of the mounting bracket and should adhere to the ROPS structure above the mounting bracket. The area that is directly above the mounting bracket should stay free of tape. The area that is directly above the mounting bracket is the area designated for upper clamp. Apply pressure on the mounting bracket in order to squeeze out the excess adhesive. Glass beads in the adhesive will prevent the adhesive from being completely squeezed out. Remove the excess adhesive around the perimeter of the mounting bracket.

14. Install clamps (A) in order secure mounting brackets.

    1. Attach clamp (A) to the ROPS structure next to the lower part of the bracket and do not tighten.

    2. Attach the clamp (A) to the ROPS structure next to the upper part of the bracket and do not tighten.

    3. Tighten both clamps simultaneously by pulling the toggle levers down.

    4. Remove the masking tape.

15. The adhesive should be visible around the perimeter of the mounting bracket with no gaps or voids. Having gaps and voids can potentially create pockets that collect water and oil.

16. Special care should be taken in order to make sure that the adhesive will not expand into the location of the clamp.

17. The bead of adhesive around the mount bracket is allowed. Provide the final cleaning around the perimeter of the mounting bracket of the excess adhesive once the adhesive has reached handling strength. Handling strength is normally reached in 15 minutes at room temperature.

Time to 6900 kPa (1000 psi)1000 psi Handling Strength (min)	50	37	25	20	18	13	11

Curing begins immediately once the adhesive and the accelerator have been mixed. Handling strength is achieved within 16 to 24 minutes of mixing. Complete curing will take 8 to 24 hours depending on the temperature and the bondline thickness. Mating surfaces must be held in contact during the entire cure period. Adhesive will cure to a tack free surface.

Equipment Cleanup

Clean the equipment and the tools prior to the adhesive curing with solvents such as isopropyl alcohol, acetone and methyl ethyl ketone (MEK). Once the adhesive has cured, heating the adhesive to 204° C (400° F) or above will soften the adhesive. Softening the adhesive allows for the parts to be separated and the adhesive to be removed more easily.

Removal of Mounting Bracket

Illustration 39	g03819444
Heat gun for the removal of the mounting bracket

In order to remove a mounting bracket, the mounting bracket will need to be heated. Preferably use a heat gun to get the mounting bracket near 260° C (500° F) and apply pulling force. The adhesive will soften and allow the mount bracket to be removed. Once the mounting bracket has been removed, heat the remaining adhesive on the structure and remove the adhesive with a putty knife. After the adhesive has been removed, use solvent for the final cleanup.

Other nonmetallic components that are located next to the mounting bracket may need to be disassembled prior to applying heat as they may get damaged at elevated temperatures. Appropriate burn hazard and eye protection equipment must be worn.

Shelf Life and Storage of Adhesive

Shelf life is six months when stored at temperatures under 27° C (80° F) in the original unopened container. For maximum shelf life of the adhesive, storage temperatures of 4° to −10° C (40° to 50° F) is recommended. If the adhesive is stored at the above cooler temperatures, allow the adhesive to return to room temperature before using. Protect the adhesive from exposure to ultraviolet light.

LORD 606 acrylic adhesive is flammable. Do not store the adhesive or use the adhesive near heat, sparks or open flame.

Mass Carrying Capacity of the Mounting Brackets

The intention of this section is to provide guidance on the amount of mass that can be applied to the adhesively bonded brackets. Mass carrying capacity is given as a function of Load Arm (L = Distance from the CG of mounted piece of equipment to the mount surface with adhesive).

Bracket capacity of mass carrying is based on the stress in adhesive layer.

To install a component in the cab the installer needs to know the component weight. For a given weight the row of the table shows the max allowed distance that this component can be located. This distance value applies to both directions – horizontal and vertical. The installer needs to check both distances from the center of the bracket to CG of component at intended location – the horizontal distance and the vertical distance. The bigger of the two takes the precedence. Refer to Illustration 41 and Illustration 42.

The graphs and the tables represent the same information.

• All the components need to be securely fastened to both bracket bosses. The values in the table (or the graph) apply only to arrangements when the component is tightened securely to both bracket bosses.

• The tabulated data shown (or data on the graph) are valid for the scheme when a single piece of equipment is mounted on a single mount bracket. Other schemes need to be separately evaluated. For example: using two brackets to mount a single piece of equipment. Schemes like this result with increased Load carrying capacity.

• Brackets have to be installed in vertical position – as demonstrated in Illustrations 33, 34, 35 and 36.

• For cases other than described above please contact AVSpare for support.
