There are different types of boat repair jobs which can be both a minor or major work. However, if the damage is on your boat trailer, then you will require the proper tools as well as a detailed guide to help you fix the damages. Below is a step-by-step guide on how to repair common damages to a trailer.
Step 1. Fixing the Lights of a Boat Trailer
If the problem is on your trailer lights, you first need to check which light is malfunctioning. Once you have determined which light is damaged, you can go ahead and fix the problem. To do this, check the pin of the trailer connector to verify if it has enough power. Use the test light for this one, preferably a 12-volt tester.
Step 2. Replacing the Trailer Lights
Once you have found the area where there is no power, unscrew the lights from the terminal and remove any rust or dirt on the connection. Replace the light bulb with a new one, making sure that the new bulb is the same type and size as the old one. Also, replace the old screw before you screw the terminal back onto the connection. Test the lights again.
Step 3. Fixing the Wheel Bearings of the Trailer
If the damage is on the wheel bearings of your trailer, you need to raise the trailer, making sure that you jack only one side at a time. Secure the trailer with a jack stand. Make sure that you remove the wheels and lug nuts before you raise the trailer. Check if there is any grease on the wheel, side hub, or tire. If grease is present, then it means the seal is broken and needs to be replaced.
Step 4. Removing the Wheel Bearings
After securing the trailer with the jack stand, you can now remove the hub by first removing the bearing protector or the cap. Turn the hub once the protector is removed. Once the protector has been removed, remove the cotter pin. To do this, bend the cotter pin so it is straight and use pliers to pull it out. You then have to remove the washer and castle nut as well as the outer bearing. Make sure you have enough rags to catch any grease from splattering.
Step 5. Clean the Bearing Parts
Clean all the parts that you have removed with cleaning fluid, making sure that you remove all the grease stuck on each part. Wipe off any dust as well. Once everything is clean, dry it out with a rag. Make sure that the parts are completely dry.
Step 6. Greasing the Bearing
When everything is dry, repack bearings and install the back one in hub. Install new seal in hub and replace hub on axle. Install outer bearing, washer, and castellated nut. Tighten nut by hand and rotate hub. Do not overtighten nut. Replace cotter-pin and re-install dust cup.
