The top picture is an orvis 150 pinion gear with a frozen shaft. Heating has not been successful in moving it. The bottom is a ted williams 310. Same problem.The shaft spins but doesn't oscillate as shaft is stuck. Suggestions to soak?? I have tried liquid wrench and alternate heating..suggestions
For me, I use a cigar tube (metal or glass or plastic) and let it soak in the tube using PB Blaster. It has worked for me several times. It sometimes takes a couple days but patience has paid off in my case. If you feel the need to use a vise and a hammer to help persuade it a little, I use a hard wood dowel to prevent hitting the shaft with the actual hammer with a towel in the vise. What ever way you do it, good luck!
I soak them for awhile like Randy says, then I put the pinion in a hole in a piece of hardwood or put it a vice so the bearing flange is being supported against something hard and then lightly tap the rear end of the shaft while the crosswind screw is threaded in the hole so as not to mess up the hole or threads. Once the shaft moves a little I remove the screw and tap the shaft on through the pinion tube using a correct size flat ended punch or cut off a correct size nail and use that. Once the shaft is out I burnish the heck out of both the shaft & tube so that the shaft moves freely.
You can also hold the pinion, install the crosswind screw and try to turn the shaft inside the pinion to loosen it up that way, but it looks like someone already tried that. The shaft in the first picture is pretty marred and beat up and is going to take a lot of filing and TLC to get it true and working correctly again. :o
A different set of components but a similar problem for me solved today, a frozen ferrule on a salt water spinner. Been playing with it for months, a little blaster for a week every day in a vertical rod rack. Yank pull twist. Nope. 2 guys yank pull twist. Nope. Simple machines and a fixed point occurs to me.
The cellar has a few stout steel posts bedded into the cement floor.
First attempt clove hitch on the fiberglass below the ferrule with paracord then a few more wraps but tuck the line under itself so each wrap becomes an additional hitch, same on the other side of the ferrule. These multiple clove hitches bind to and don't slide on the glass under load. One end to low stretch PE rope tied to the post The paracord on the other side as tightly as possible to the closed vise jaw. Unfortunatly the post is 20 feet away and the screw as I open the vise pulling on the ferrule just isn't long enough to pull things apart as the fibers in the cordage stretch.
Second try. 2 posts 12 feet apart, tie the paracord directly to one post. Attach a small block and tackle (1/4 braid) to the second post fastened to the paracord on the other side of the ferrule. Tie a loop on the working end of the tackle large enough to pull up like a pair of jockey shorts so I can lean into with by butt thereby powering the entire operation. Straight pull is a failure but the butt bounce maneuver yeilds movement, unfortunately it is the glass pulling a thirty second inch out of the ferrule. Intermission. Return with a torch to tickle the ferrule then the third butt bounce achieves success. A note of interest, the blaster had penetrated all the way into the ferrule.
Perhaps some of my Rube Goldberg solution may be transferable to your problem if you can find an anchor point on the components.

One of the main problems with ferrules is that when they fit extremely tight a suction is created that is near impossible to break free unless there is a slight gap for air to stabilize. Once that sweet spot is found they'll usually separate fairly easily. It's a little different situation when old grease hardens and turns to glue &/or corrosion.
Thanks. The orvis 150 shaft was from a parts bin with broken rotor. Salvaged everything but this shaft. The 310 ted williams was also in this pile and parts bin. Trying to rescue as many parts as i can.
have you considered a press to make the break?
Don't understand the idea of a press? Explain or a link to something on internet. Thanks
Try putting it in the freezer.
Found it works on screws.

It`s a mechanical device to push apart / or install parts .

Some times you can use a drill press in a pinch !
Thanks. Bet you my car mechanic has one!
