Greasing problem

[Woodworks]

Picked up a forwarding trailer and crane some time back and I give the crane a good greasing when used; well so I thought. Was merrily pumping some grease into a hidden away nipple and as I removed the gun noticed the grease nipple was loose and the grease had just come out the back of it and not into the bearing. On close inspection with a torch I don't think any grease had got into the bearing since I got hold of it. I tried to drive out the pin to get the ram off to sort this but the pin will not budge. I can get the other end off the ram which looks the same so have taken a picture of that so can see what I am on about. Any bright ideas on how to get this working again or how to remove the pin without beating seven bells out of it?

 

First two pics are the stuck pin and last one is of the other end of the ram which has the same bearing and greasing arrangement as the bunged up and stuck end.

 

Thanks

Have you tried changing the grease nipple?

Sadly no problem with the nipple as that would be a nice easy fix

Gently heat the metal around the bearing. Enough to make the old grease move fluid. Push it all out by pumping new grease in. The channel is likely blocked with dried out grease. It doesn't need to get mega hot I'd of thought a propane butane mix torch should get it warm enough

That might be worth a go.

 

Access is awkward so do think a hot air gun might work?

The pin should come out, just make sure any retaining pin/bolt/circlip has been removed, pressure is off the ram then give pin a batter with the biggest persuader you can lay your hands on and it should move.

There isn't a roll pin either in the thickness of the frame of the outer eye ,or behind it and between it and the ram eye by any chance. There must be a securing pin somewhere that you just haven't found

Did give it a few whacks but it didn't budge. 20mm drift and a sledge hammer . Had removed the retaining pin and no pressure on the ram. Didn't want to keep hitting it like that in case I rounded over the end of the pin and then it would never come out.

If you look closely at the middle pic you can see the hole where the split pin was. Could there be something else? I removed the other end of the ram without any snags. Just removed pin and few sharp taps and out it popped.

Has the pin been put in and then the metal guard been welded on to stop it coming out? It looks like the one side has a shoulder on it so it has to come out the side of the welded on plate.
