Shields and Skirts<br />
Check shields and skirts for cracks at mounting and stress<br />
points. Check fender shields for tire marks, worn spots,<br />
or damage from objects thrown from tire treads. You can<br />
repair cracked or damaged fiberglass fender shields with<br />
fiberglass and resin.<br />
If you find damage at a fastening point, you can gain additional<br />
strength by installing a suitable reinforcing plate.<br />
This plate should be drilled to accept a rivet and laminated<br />
totheshieldwithfiberglass and resin.<br />
Check cab skirts, sills, and brackets for overall condition<br />
and repair them as necessary. Damaged rubber fender<br />
shields or cab skirting cannot be repaired. You will need<br />
to replace it.<br />
Your authorized dealership can perform all of these checks<br />
and repairs or replacements.<br />

may result in serious damage to the engine. If<br />
you do not repair them the engine damage won’t<br />
