Coats Tire machine repair - need advice

[malbojah]

I picked up a used Coats RC-20A last year from a widow for good money, the only downside was after I got it home I found that the rotary coupler was ******* air (cracked plastic fitting). I have a new one on order but I was hoping to get it out while I'm waiting.

I have the air cylinder and turntable off, leaving me with the spider legs that feel like they're pressed in. I've already been whacking it with a mallet with no success.

Gear puller? Lube?

Changed a RC on one a couple years ago, was fairly intuitive once I got into it, but can't remember the details.

Use some heat and a two armed gear puller on it.

Well after soaking in penetration oil for 36 hours, the spider legs pulled right off. Somebody previous to me has packed the splines with a lot of grease making it easy to remove. The coupler came off once I put it in the vise and gave a good tug. Now I'm just waiting on UPS to get me the new coupler today.
