At the start of every project you will need to start hitting nuts and bolts with penetrating oil for rust. This usuall takes a couple of squirts on all bolts that are rusted over. |
|
On the MBT and T3 trailers, there are castle nuts with cotter pins holding them in place. These can be frozen and/or very brittle. First, straighten the cotter pin out with needle nose pliers |
|
Now, take some snipes and clamp down on the top or hook part of the cotter pin and hold tight without cutting. |
|
With a good grip on the snipes, take a hammer and pound the snipes so the force on the cotter pin comes flying out. |
|
If the cotter pin breaks, then follow the same steps with each piece that remains in the hole. If needed, swtich ends, and try from the other side. |
|
With rusty parts, you can still have issues with breakage. If the cotter pin breaks, thus no grip with the snipes, then use a small punch or ice pick and try and tap one side of the cotter pin out where you can grab it. |
|
As a last resort, use a small drill bit, and drill the cotter pin out. Be sure to use a smaller drill bit than the existing hole. |
