Today on this enclosed trailer we are going to replace the jack on it and we are going to be using part number BD155032 from Bulldog. This is their round A-Frame jack with topwind handle. The capacity of this jack holding the trailer by itself is 5,000 pounds and also while it is lifting it is ready for 5,000 pounds also. Basically to replace it is going to be pretty easy. Just give it a go and see if it comes apart. We have got these three bolts to remove and you should be able to just remove the jack straight up. You will also notice we have got the trailer hooked up to our truck that way we have it supporting the trailer pretty easily so we can remove the jack. In our case here we are pulling it up and it catches. That is because the bottom of the jack has been ground down from abuse and dragging and what not. So honestly we are going to take a grinder and cut off the bottom. It does not matter because we are going to have to replace the whole thing. 01:04
Lets install the new jack. Now we have got the bolts off and our new jack into place. One thing you want to notice that some bolts from the original manufacturer are probably a little bit shorter than these bolts here. These are nice long length ones so we are going to reuse those and add some washers to the top. You do not have to add the washers but I like the idea of having additional force on the steel itself considering what the head is compared to the slot. If you have the short bolt you might not be able to use the washers but the best way to work around it is to get some more 3/ 8 hardened bolts and start fresh anyway. What we have got here are plenty long so we are going to add three conical tooth washers. They do not have to be conical tooth but just anything to help spread the force around. We just had these lying in the shop so I grabbed those. We will simply run them down, we will snug them down, and then tighten them down hand tight. You can see where the original jack was painted on the trailer. The new jack obviously is not the same one but they all tend to share the same common bolt pattern. There are a few variances so that is why they had to leave the holes as an oval. Once they are all seated maybe 1/ 8 of a turn, 1/ 4 turn. With the bolts tightened down that will finish our install of the new jack. There you have it for part number BD155032 from Bulldog.
