trailer hitch ball size for 1957 aljo trailer

[Primolee]

Hi everybody, I have a 1957 aljo trailer that has not been moved for years and I can not find a trailer ball that will fit it, I tried a 2" and way too big, I tried a 1 7/8" ball and still too bid. Does anyone have an idea or a similar trailer with any info? It has not had a ball in it for years but I believe I have been opening the hitch all the way. If any one can help I would REALLY appreciate it.
Thanks, Bill

Just ignore this.
Use some penetrating oil, and work the latch open and closed. If you are sure it is open all the way and 1 7/8 will not fit, then might as well replace the coupler.

We once had to cut off a 1 3/4" coupler because we couldn't find a ball that size. I don't think anyone makes them anymore.

Maybe asking a vintage club could answer your question

Hi Primolee welcome to the forums.

Could the coupler be rusted shut to the point that no ball is going to go in? You might have to lay on the ground and look up under the tongue. then try moving the latch or lever and observe if the piece that grabs under the ball is moving.
