Can a Trailer Jack Be Rebuilt?
Yes, you can rebuild a trailer jack!
You’re going to need several separate components to rebuild a jack. Some of these jack accessories include:
1. A handle and the handle pin.
2. Internal bearing.
3. The top plate
4. Side gear.
5. Base gear.
6. Keeper ring.
However, they might differ according to the type of trailer hack you’re using. You can also choose to purchase a new trailer jack, for instance, any of these electric horse trailer jacks.
Here’s how you rebuild it.
Remove the jack’s cap and lift the upper edge once you’ve pulled on it. If your jack doesn’t need repairs and you only need to replace the cap, just screw a new one on.
However, you can take the rebuilding a few steps further.
The jack will contain quite a bit of grease and potentially some debris. You’ll have to clean that out before you can think of rebuilding it.
How to Fix a Trailer Jack? Steps To Follow
If your trailer jack does not move up and down correctly when it should, this is the guide for you.
Step 1: Get the fault off
Use an adequate side wrench to detach the fault from the side. This will let you take out the handle.
Step 2: Apply the grease
Once you uncover the jack bearings after removing the jack washers, apply a coat of grease inside the bearing and outside. Then, take a look at the inner screw.
Clean it thoroughly before you rub the grease onto it. One of the most likely reasons why your trailer jack might need fixing is that it needs lubrication.
Step 3: Retracing your steps
Fix the bearing right back onto the end of the jack. Test out the jack and see if it is working correctly once again.
Be sure to replace the washers. This should take you anywhere from half an hour to forty-five minutes. There isn’t a lot of difference in trailer jacks.
If you know how to use and fix one, you’ll know how to do it to the rest.
