Liqua-lube Hub Sizing Chart

HOW TO SELECT THE CORRECT LIQUA-LUBE® HUB LUBRICATION SYSTEM

It is important that you are using the correct model of the Liqua-Lube Hub Lubrication System for your trailer. Each Liqua-Lube System contains the correct seal and sleeve to accommodate a specific spindle size. Your dealer can help you in determining the correct model needed. If you choose to install the Liqua-Lube System yourself, use this handy sheet to determine your spindle and hub size by following these three steps:

1. Using a calipers, measure the diameter of the spindle at the point where the seal rides when the hub is on the spindle (A). This measurement corresponds to the spindle diameter on the chart below. If spindle has an existing spindle sleeve, measure the sleeve. The measurement will be .020” to .060” larger than the measurement on the chart.

2. Remove the seal from the hub and measure the inside diameter of the hub where the seal was positioned. This measurement corresponds to the hub inside diameter on the chart.

3. To determine the proper model match your spindle and hub size to the Liqua-Lube part number on the chart below. 

NOTE: One-fourth inch of wall thickness on the face of the hub is needed for the screws to secure the Liqua-Lube® Cap.
