The installation of nerf bars on a 66-77 Early Ford Bronco involves securing mounting brackets to the vehicle’s frame and body, followed by attaching the nerf bars themselves. The process requires specific hardware, tools, and careful attention to potential obstructions. This guide details the steps, required components, and safety precautions based on provided documentation.
Kit Contents and Required Tools
The 66-77 Early Ford Bronco Nerf Bar Kit includes the following components:
- 2 Front Mounting Brackets
- 14 3/8” x 1-1/4” Bolts
- 14 3/8” Lock Washers
- 14 3/8” Nuts
- 6 3/8” Flat Washers
The following tools are required for installation:
- Hammer
- Centerpunch
- 9/16” Socket
- Drill Motor
- 3/8” Bit
- Marker
- 1/2” Ratchet
Pre-Installation Safety Precautions
Prior to commencing the installation, a cautionary note emphasizes the importance of thoroughly reading the instructions. A warning is issued regarding potential damage to brake, fuel, or electrical lines during the drilling and tightening phases. It is crucial to inspect for obstructions before tightening bolts or drilling, and re-routing lines if necessary to prevent costly or dangerous consequences.
Front Mounting Bracket Installation – Step 1
The initial step involves locating and removing the front mounting bracket. This bracket is then attached to the welded front bracket on the vehicle using four 3/8” bolts, nuts, and washers. The documentation specifies the use of the hardware provided within the kit.
Rear Mounting and Leveling – Step 2
Following the front bracket installation, the nerf bar is raised until it is level and parallel to the vehicle’s body. At this point, the locations of the holes in the front mounting plate are marked onto the forward side of the front body mount. This marking is essential for the subsequent drilling process.
Drilling and Securing – Step 3
With the bar set aside, 3/8” holes are drilled at the marked locations on the forward side of the front body mount. The bar is then re-positioned and secured, first at the rear using the factory perch nut, and then at the front to the body mount using the 3/8” x 1-1/4” bolts, nuts, and washers provided in the kit. All bolts are then tightened completely.
Opposite Side Installation – Step 4
Steps one through three are repeated on the opposite side of the vehicle to complete the installation of the nerf bars. This ensures symmetrical mounting and even weight distribution.
Post-Installation Maintenance
The documentation recommends periodically checking all bolts and nuts for tightness. The frequency of these checks should be determined by driving conditions and habits. Regular maintenance ensures the continued secure attachment of the nerf bars.
Detailed Breakdown of Hardware
The hardware kit contains specific quantities of each component. A detailed list is provided for inventory and reference during installation:
- Bolts (3/8” x 1-1/4”): 14
- Lock Washers (3/8”): 14
- Nuts (3/8”): 14
- Flat Washers (3/8”): 6
Cautionary Notes Revisited
The documentation reiterates the importance of carefully reading the instructions before beginning the installation. The warning regarding potential damage to vehicle lines remains paramount. Prior to drilling or tightening, a thorough inspection for brake, fuel, and electrical lines is essential. Re-routing these lines, if necessary, is emphasized as a preventative measure against costly repairs or hazardous situations.
Conclusion
The installation of nerf bars on a 66-77 Early Ford Bronco requires a specific set of tools and hardware, along with careful adherence to the provided instructions. Prioritizing safety by checking for obstructions and ensuring proper tightening of all components is crucial for a successful and secure installation. Regular maintenance, including periodic bolt checks, will contribute to the longevity and reliability of the installed nerf bars.
