NP205 XFer Case, Front Output Yoke Stuck On Shaft

1974 Dodge W200 PowerWagon, NP205 Transfer Case.

The oil seal for the Front Output Yoke is leaking, so I'm Trying to remove the Front Yoke.

I removed the Nut and Washer with an Pneumatic Impact Gun.

I have sprayed the yoke and shaft splines with PB Blaster and Kroil penetrant and let it soak several times. My two jaw puller (medium duty) failed. A bolt sheared and a hook end broke off the puller. Not sure, but I don't think the yoke budged a bit in the attempt.

I am considering buying a Heavy Duty two-jaw puller tomorrow.

If I had the truck at home (it is at a storage site) I might break out the acetylene torch. With as much grease present (haven't owned the truck very long, I still need to scrape/clean it at some point) but as of Right now, it might catch fire if I use an open flame.

I suppose I could try using an electric heat-gun or a propane torch.

Is this unusual for the yoke to be on this tight? Is there any good advice on how to remove this yoke?

I have had luck with a 2 bolt puller in the strap bolt holes.

snug up the puller tight and hit the end with a hammer then torque on the puller tap with hammer ect..

electric or air impact helps to torque puller. add a little heat while the puller is torqued and yoke is under pressure as it heats up then tap with hammer.

good luck

Thanks.
