How to Measure Your Bolt Pattern

Accurate measurement of your wheel’s bolt pattern is essential for selecting the correct 2000 lb Hub and Drum assembly. The bolt pattern consists of two numbers: the number of bolt holes and the diameter of the circle they form.

  • Even Number of Bolts: For wheels with an even number of bolt holes, measure from the center of one bolt hole directly across to the center of the opposite bolt hole.
  • Odd Number of Bolts: For wheels with an odd number of bolt holes (like 5), measure from the center of any bolt hole to a point halfway between the two bolt holes directly opposite.

For a 5 on 4.5″ bolt pattern:

  • Measure from the center of one bolt hole, skip one and measure to the outside of the third. This measurement should be 4.5 inches.

Accurate measurements ensure compatibility and safe operation when installing your hub and drum assembly.

Simple Instructions for Measuring a Trailer Hub and Drum Bolt Pattern and Other Considerations Before Purchasing a Replacement

Part 1: Measuring the Bolt Pattern

Understanding your trailer’s bolt pattern is crucial when selecting a replacement hub and drum. Here’s how to measure it:

Step 1: Identify the Number of Lug Holes

• Count the Lug Holes: Determine how many bolt holes (lugs) are on your hub or wheel. Common configurations are 4, 5, 6, or 8 lug holes.

Step 2: Measure the Bolt Circle Diameter (BCD)

The method to measure the bolt circle diameter varies depending on whether you have an even or odd number of lugs.

For Hubs with an Even Number of Lugs (4, 6, 8 lugs):

1. Measure Across the Center:

• Place a ruler or measuring tape over the center of the hub.

• Measure from the center of one lug hole directly across the hub to the center of the opposite lug hole.

2. Record the Measurement:

• This distance is your bolt circle diameter.

Example: If the distance between opposite lug holes is 4 inches, your bolt pattern is “4 on 4” (4 lugs on a 4-inch circle).

For Hubs with an Odd Number of Lugs (5 lugs):

1. Measure from Center to Outer Edge:

• Measure from the center of one lug hole to the outer edge of a lug hole that is directly across from it (skipping one lug hole in between).

2. Alternatively, Use the Chord Measurement Method:

• Measure the Distance (D) between two adjacent lug holes (center to center).

• Use a Multiplier: Multiply this distance by 1.7012 to calculate the bolt circle diameter.

text{Bolt Circle Diameter (BCD)} = D times 1.7012

3. Record the Measurement:

• Round to the nearest common bolt pattern size (e.g., 4.5 inches, 5 inches).

Example: If the distance between adjacent lug holes is 2.75 inches:

text{BCD} = 2.75” times 1.7012 approx 4.68”

This approximates a 5 on 4.5” bolt pattern.

Step 3: Determine the Bolt Pattern Notation

• Express the Bolt Pattern: Use the format “[Number of Lugs] on [Bolt Circle Diameter]”.

Examples:

• “4 on 4” means 4 lugs on a 4-inch circle.

• “5 on 4.5” means 5 lugs on a 4.5-inch circle.

Part 2: Other Important Considerations Before Purchasing a Replacement Hub and Drum

To ensure safety and compatibility, consider the following factors before buying a replacement hub and drum:

1. Axle Capacity

• Know Your Axle Rating: Check your trailer’s axle weight capacity (e.g., 2,000 lbs, 3,500 lbs).

• Match the Hub and Drum: Purchase a hub and drum assembly rated for the same capacity.

2. Spindle Type and Bearing Sizes

• Identify Spindle Type: Determine if you have a straight or tapered spindle.

• Check Bearing Numbers:

• Remove the hub to access the bearings.

• Look for part numbers stamped on the bearings (e.g., L44649, L68149).

• Measure Bearings if Needed:

• Inner Bearing ID: Diameter of the inner bearing opening.

• Outer Bearing ID: Diameter of the outer bearing opening.

• Ensure Compatibility: The new hub must accommodate the same bearing sizes.

3. Grease Seal Size

• Check Seal Numbers: Look for part numbers on the grease seal.

• Measure if Unmarked:

• Inner Diameter (ID): Diameter where the seal fits over the spindle.

• Outer Diameter (OD): Diameter where the seal fits into the hub.

• Match Seal Size: The new grease seal must match these dimensions to prevent leaks.

4. Brake Type and Compatibility

• Determine Hub Type Needed:

• Idler Hub: For trailers without brakes.

• Hub and Drum Assembly: For trailers with drum brakes.

• Brake Size Compatibility:

• Ensure the drum matches your brake assemblies (common sizes are 7”, 10”, 12”).

• Check Brake Hardware:

• Verify that the hub is compatible with your existing brake components.

5. Wheel Compatibility

• Confirm Bolt Pattern: Ensure the new hub’s bolt pattern matches your wheel.

• Check Wheel Stud Size:

• Common stud sizes are 1/2”-20 or 9/16”-18 threads.

• Center Bore and Offset:

• Make sure the hub’s center bore fits your wheel.

• Consider wheel offset if applicable.

6. Spindle Type: EZ-Lube vs. Standard

• Identify Spindle Type:

• EZ-Lube Spindle: Has a grease fitting on the end for easy lubrication.

• Standard Spindle: Requires manual greasing.

• Select Compatible Components:

• Choose hubs and dust caps designed for your spindle type.

7. Material and Finish

• Environmental Considerations:

• For marine or coastal use, consider galvanized or stainless steel hubs to resist corrosion.

• Durability:

• Quality materials extend the life of your hub and drum.

8. Tools and Supplies Needed

• Essential Tools:

• Wrenches or sockets for lug nuts and spindle nuts.

• Torque wrench for proper tightening.

• Pliers or cutters for cotter pins.

• Supplies:

• High-temperature wheel bearing grease (if not pre-greased).

• Grease gun (for EZ-Lube spindles).

• Safety equipment (gloves, eye protection).

9. Installation Tips

• Proper Torque:

• Follow manufacturer specifications for tightening lug nuts and spindle nuts.

• Safety Checks:

• After installation, check for proper wheel rotation and absence of play.

• Regular Maintenance:

• Periodically inspect and grease bearings to extend the life of your hubs.

10. Consult Manufacturer Specifications

• Owner’s Manual:

• Review your trailer’s manual for specific requirements.

• Professional Advice:

• If unsure, consult with a trailer technician or dealer.

By carefully measuring your bolt pattern and considering these factors, you’ll ensure that you purchase the correct replacement hub and drum for your trailer, leading to safe and reliable performance on the road.
