Working on my 56 Javeline cowl. Finally found someone to weld up some damaged spots. I would like some input from you guys as to how to take the hinge pin out without doing to much damage. Or should I leave it alone ?

The Johnson hinge pins that I’ve seen are fluted and made from aluminum. The one that I replaced was broken, and it really gave me a hard time getting it out. There may be a right and wrong direction to drive out the pin.

If memory serves me right, the straight knurled or fluted end of the pin is on the starboard side, meaning it has to be driven out from the port side. Or, it could be the other way around.

The problem is, if it is corroded in place or very tight, the end being driven will expand and lock that end in place. To avoid this, I’ve cut the pin between the hinges and replaced it with an aluminum rod epoxied in place.

On my ’56 30hp cowl, the knurled end was indeed on the starboard side. I seem to recall driving it out with a punch from the port side after I went through a few rounds of heating the 2 ends and apply penetrating oil. It’s a snug fit.

The only reason for removing it is to make it easier too blast and repaint.
If it is split it will fit in my blasting cabinet.
Not sure I want to try to remove it for fear of damaging something!!

I wouldn’t force that pin for sure, you don’t want to damage the cover. Cutting pin will help, but once it’s cut you are locked into removal. I guess I wouldn’t mess with that pin if it doesn’t come out with minimal force (once you figure out which way it should be removed, sorry I don’t know the proper method).

Well I got lucky. A couple good cracks with the hammer and it started to move. Came out the port side.

That’s good news. I worked on mine off and on for a couple hours before I got it to budge.

Came out the port side? It must have been built on a Monday morning or Friday afternoon!
