How To Measure Bearings, Seals, And Spindles For An Axle
Question:
Can you tell me what bearings and seals I need from just the axel part number? I have a DEXTER 4178284 ... Capacity 3500 lbs
asked by: Larry H
Expert Reply:
Most axles rated at 3,500 lbs will have the inner bearing, part # L68149, and the outer bearing, part # L44649. This is something you can check. The bearings and seals have numbers. They are actually engraved on the bearings and the seals. If you are unable to get that information, you can take the measurements of the bearings and the seals. You will need a set if digital calipers, something like the 4" Carbon Fiber Digital Caliper, part # PTW80157. You will take measurements of the inner and outer diameters of the bearings, seals, and the spindle of your axle.
I have included a product description link, a video demo link, and instructions on how to measure your bearings and your spindle below.
