Adjusting the pin box on 91 Nu-Wa

[Zimectrin]

Son in law just purchased a 91 Nu-Wa Snowbird fiver. We need to change the height of the pin box, but the adjustment method is not obvious.

Can anyone point us in the right direction?

Thank you for your input.

Normally they are held together with 4 to 6 exposed bolts. You take these out and lower or raise the pin 1 bolt hole set. On that age trailer it will probably be rusted and hard to get loose.

It would be easier to raise or lower the 5er hitch . These can usually be raised or lowered several inches much easier than the pin box.
