The trailer was still on my truck, so the jack was suspended. I
applied
force with my foot while turning both ways, but it didn't move. I
probably
should try to really pull it hard while turning, but in effect, I did
try what
you said, hoping it would "catch" in some way.

There is no rotate up to storage position with this jack. I guess
it's
old school! But I know the type you're talking about, with the pin
and rotating on a central bolt.

Thanks for the ideas.

I was turning the manual jack on my boat trailer today when, as the
wheel was just about at the
bottom of the jack, I heard a snap (or something like that) and now
the jack doesn't work. This jack
isn't bolted onto the trailer- it's welded on. So I'd like to try to
fix it.

Does anyone know how to diagnose and fix trailer jacks?

I popped the top cover off the jack and saw the gears and the handle
inserted into the jack
through the side. It all turns fine, and there is plenty of grease.
So it must be somewhere
between those top gears and... I'm not sure!... where the problem
lies.

If I can't fix it, I'll just buy a $30 trailer jack and bolt it on!

You could have over run the ring gear on the gear shaft.

Try jacking up the trailer tongue about six inches, then pull
the shaft down while turning the handle - that might reengage
the ring gear.

Fixing the jack may be problematic. If the above doens't
work, leave the tongue jacked up and rotate the jack to
it's storage position. When it's in that position, try to
pull the inner shaft out. If you can, then you are well and
truly screwed.- Hide quoted text -
