Rubber boat trailer rollers are an important part of a trailer. They are very useful for putting the boat onto the trailer. They rotate under the boat, and you can move it conveniently.
You may find that you need to replace these rollers, as they wear out with use. Here are a couple of guidelines for replacing the boat trailer rollers:
Step 1: Removing the Rollers
With your boat off the trailer, remove the worn out rollers needing replacement, from the front side of the trailer. Pull the cotter pins with the help of pliers. Now, push out the roller shaft from the brackets.
Step 2: Changing the Roller
Lubricate the roller shaft and the mounting bracket with lubricant spray. Replace the worn-out or damaged roller shafts, rollers and cotter pins wherever required.
Step 3: Fixing the Rollers
Hold the roller between the mounting brackets on its 2 ends. Push the roller shaft into the hole of mounting brackets, through the hole of roller. Tap the shaft with a mallet, if needed.
Step 4: Locking the Roller
Push the cotter pins into the roller shaft protruding from the brackets, to lock them in position. Split the cotter pins, so that they are secured in their places.
