How To Determine Bearings and Seals For Older Long Chih Trailer

Question:

I have a very old Long CHIH trailer about 18 years. The inner and outer bearings are the same and size axle size and same size outter diameter and both on the 1inch axle and the outside diameter of the bearing itself is about 2inch probably all metric. The grease seal in the back is on a 1.249inch part of the axle, and the outter diameter is also about 2. Do you have a bearing set for this trailer? The plate with the model has long since fallen off, so I dont know which model this trailer is.

To get the correct bearings and seal kit for your Long Chih trailer, you will want to get the part numbers that are stamped on the bearings of your trailer. There will be an inner and an outer bearing number. With those part numbers, I will be able to determine the bearings and seal you will need for your trailer.

Another way to determine the bearings and seal you will need is to use a digital caliper and measure the bearing and seal dimensions of the spindle on your trailer. Again, these have to be as accurate as possible. I am including a link to a video that will show you how to take the measurements on the spindle.

It sounds like you might have the BT8 Spindle, part # TRU94FR, on your trailer which is for 2,000-lb axles. This spindle uses the Bearing Kit, part # DL21792, that has the same inner (# L44643) and outer (# L44643) bearing and a grease seal (# 34823) with an inner diameter of 1.249 inches and an outer diameter of 1.980 inches.

The # DL21792 bearing kit will include one inner bearing and race, one outer bearing and race, grease seal, cotter pin, and a grease cap.
