Just picked up a 76 FXE super glide for dirt cheap. Previous owner left primary cover off and was left out in southeast TX weather for months. The primary is full of sand and rust. As soon as I got it home, I started disassembling the primary. I purchased the puller from harley and attempted to use it. IT WILL NOT BUDGE! I applied heat with MAPP gas and a oxy/ace torch and tried to shock it with a mini sledge. Still nothing. I ended up pulling one of the studs out. Now, I don't have an even pull.
Out of disparity and what I've read on other forums, some have used gear pullers. So, again, used a 3 jaw and 2 jaw pullers and ended up damaging the hub even more. I can't seem to get any kind of leverage to remove it.
ANYONE HAVE ANY TIPS OR SUGGESTIONS TO GETTING THIS HUB OFF?
Thanks!

 

I've seen this before.
I wound up having to cut the clutch hub off the shaft with a ox-acetylene torch.
I was very careful to not hit the transmission shaft but it boiled down to just luck that it was not hurt.
Before you go that far, maybe you can get a 3 inch disc cutoff tool to cut mostly through the thick metal of the hub and then try higher heat from an ox-acetylene torch to heat the hub.
If you have the cutoff tool, cut all the clutch studs off to get them out of your way so you can get to that thick part of the clutch hub.
What you are looking to do is cut as deeply into it as you can without hitting the transmission shaft.
Unless you get lucky I think you are in for a real fight getting that thing off if it doesn't want to cooperate but it can be done.
Oh, before you go to this extreme, have you soaked that thing with penetrating oil for a few days?

 

see this all the time - and contrary to what was said you load the tool ( tighten the bolt ) and with a brass hammer give it a shot then tighten the tool if it did not pop off do it again

 

Thanks for the responses and helpful insight, guys!

I've attempted to use a 5", 4-1/2", and 3" cut off wheel. I cut the studs off and tried to get as close to the key way as possible to hopefully use a chisel or wedge to split the hub. Unfortunately, its a hardened metal and had no luck. And trying to not knick the shaft or damage the inner primary makes it tedious. Even tried drilling and tapping new holes to maybe put a harmonic balancer puller but still no dice.

This past week I've tried the 2 jaw puller and holding tension on the outer-part of the hub. Spraying it with penetration oils and letting it sit with tension. Just not sure if that's enough pressure for it to come loose.

Ive considered using a cutting torch and seen someone do that. Just trying to use that as a last resort. Don't know how confident I am getting close to that transmission shaft but I might have to resort to doing that. Just not having any sort of luck with it...

 

do you know the blue line indication when grinding? when the metal you are grinding gets very thin, it turns blue because it can't dissipate the heat any more. that's when you stop grinding. move to another section and repeat until you can pop the hub off.

 

 

no he cut of the studs used to remove the hub with the tool

 

What's happening with this?
Did ya get it off yet?
Here's another idea if it's still stuck on there, johnjzjz is sure it'll come off with a clutch hub puller.
I know you have cut off the studs to allow for a cutoff tool but if you want to try the puller again you can weld bolts onto the hub and try the puller again.
Weld the heads of the bolts to the hub and use the puller as designed with nuts holding it in place.
Do you have an electric welder?
Mig, tig, or stick will work.
