In this video me and my dad work on swapping the axles on the farms flatbed straw trailer. We didn’t want to spend too much on job so we tried to do it as economically as possible but still make a good job of it.
My dad removes the old axle while I work on fabricating the beam for the replacement bogie axles to pivot on.
I flame cut the pivot plates out to help get a good round hole for the pin and then quickly ran the reamer through them to clean up the hole. These were tack welded into position onto the 120x120x10 box section using a long pin through them all to line them up. Inevitably the welding distorted the box section so I used the flame straighten technique to help straight the box back out, it wasn’t perfect but near enough for its purpose.
When it came to fitting the axles to the box section we realized the bushes in the axle pivots weren’t actually 2” like we thought, so my dad made up some new bushes while I removed the old ones and cleaned up the holes.
The next issue we ran into was that the axles pivots weren’t inline which meant the half length pin wouldn’t fit. We solved this by using 4 individual pins which was probably a better idea anyway but still the pivots should have been inline.
Once the pins were in, we sat the axles on the trailer and used a string line to make sure they were running straight. After tacking them on I decided the axle beam box section needed notching into the chassis to bring the ride height down, I used the gas bottle to cut a 90mm notch out. The axle was sat into the notch and then I welded around the box section using my new Jasic welder.
