seized jockey wheel help

[PeterM]

Getting round to stuff on my new trailer and I need to free up the jockey wheel and also the light board bars and threaded screw on bits that secure them.

Any suggestions as both are solid....

Stock answer - jump in a time machine and go back and grease them!!

Or penetrating fluid, leave a while, careful application of heat, brute force etc...failing that angle grind the offending parts and replace.

Penetrating oil as per Max's suggestion (Plus Gas is best IME). Get some decent heat into them if you can (blowlamp/oxy acet). Once you get them to turn, don't try to wind them out all in one go. Go backwards and forwards (like you would when cutting a new thread with a tap).

Best portable heat is one of these burning the MAPP gas:

Just about the next best thing to oxyacetylene, the garage have taken a seized on prop off a Halmatic 40 with mine and that's 10+kg of bronze to get hot

First use penetrating oil as above then burn 'em

Note of course that lots of heat doesn't do galvanising a lot of good. I don't know if you'd get to the point of creating the sort of nasty fumes that welding on galv will create, but if you do, hold your breath!
