SKI PYLON RING REMOVAL

Hello all, I want to add a pylon extension to my 75 Ski Tique, but I have to remove the ring on the top of the existing pylon to slide the new one over the top.
   The guy at the shop said to put penetrating oil at the joints for a couple of days and to remove the spring pins with a drift.
The problem is I don't see any spring pins. In fact I dont even see where the chrome plated alloy ring "core" is inside the 2 spring pin holes.
   Could I strap the ring with a come-along and try to pull it out from above?

Any experienced ideas??

I was thinking if I could put an oak dowel inside the ring, close to the inner diameter of the ring and strap it on both sides I wouldn't warp out the ring during removal.
Also, after letting it soak a couple of days in the penetrating oil I could spray the top with chewing gum remover to cool it down and then heat the pylon with a propane torch.
Would the aluminum expand more that the alloy core?
Now that I have spayed it, I have a couple of days to think up wacky ideas.
Maybe I should remove the pylon from its base in the floor and take it to a machine shop.

We pulled and pulled on our pole but it wouldn't budge from the floor, tried jacking it and everything but the fiberglass was gonna give way first so we left the sod in. It could prove pretty frustrating.

I spoke with a mechanical ENGR. He said it might be a pressed fitting in which they make the shaft a few thousandths bigger than the sleeve, heat up the sleeve, and press it in with a 5-10 ton press.

I guess the way to test this would be to saturate it with penetrating oil for a few days, heat and cool it several times, wrap it in leather and put a pipe wrench on it to see if at least it would loosen. The trick would be to use 2 pipe wrenches so you don't twist it out of the floor.

i have no need for an extended pylon but with all the trouble i've heard over the past several years if i did want one i think i would fabricate a base for the extended pylon that mounts like the factory pylon.

Best idea yet, IMHO.

I suggest the pylon be removed from the boat BEFORE trying to remove the ring in order to avoid any damage ot the floor.

Lots of good advice. I am going to soak it for a couple of days.
Just for information purposes, I bought an air boom for a good price that is made to slip over the pylon. It may not turn out to be a good price if I can't fit it to my boat, but anyway, the air boom would be so simple to use since I store the boat in my garage.

75 tique's flight pipe idea might be the simplest way to go. I am also waiting on my brackets and stern plates form alloy marine.

There is a company on Ebay that has hardware to connect to the pylon & keep the ring on. It attaches to the bottom of the pylon & you can use a boom or extended pylon.
Here is the link:

I guess I didn't look close enough. This allows you to add a boom with the extended pylon.
