Rebuilding engine, actuator-sleeve stuck in rear iron, w/pic.
 
Like the title says.

Ive soked the iron in purple-power for hours.
Ive been able to move it a little with pliers, screwdriver, and a hammer, but its not enough. In the process Ive already damaged the sleeve a little, so I don't care for its well-being.

How do I get that thing out of there without damaging the iron?

pry it out with a piece of wood.

also, if that doesn't work. try bashing on it. 6 port irons are cheap.

Forget wood.
I did this with two hammers, two flat head screwdrivers and a punch.

I haven't damaged the iron much, there is a little damage on that edge of the port toward the inside near the oil-seal track. Nothing a little porting cant help.

What I'm pondering next is getting in there with a variety of cutting tools, to chop that sleeve up into little pieces, just to get it outa there.

Any more suggestions will be appreciated.

What caused it to get stuck?

Typically it's carbon or corrosion...
Using a penetrant like WD-40 / Liquid Wrench / P'Blaster should've been a lot more effective. :(

Wow.

+1 for WD40

I'd try running something through the holes and rigging up some sort of reverse press whilst prying on the backside and giving it a good rap.

(sounds alot like what I did to your mother last night!)

That iron looks badly worn anyway, it will need lapping.

Have you tried a slide hammer? Amazing tool for stuff like this...

NoviceRotaryTech. 10-07-07 06:27 PM

Ok, I used PB-blaster, then made a slide hammer using a batt. hold-down rod, bolted the rear end-plate to the table.
And worked away at it.
Nothing much happened except the bolt that I slid through the hole that I made in the sleeve so the slide hammer had something to hook to, tore the hole apart.

So I went back to beating the hell out of that POS sleeve with the hammers, screwdrivers, a punch and a chisel.

And finally got it out. The rear end-plate didn't sustain to much damage.

BTW: last picture, thats carbon build-up in there.

How in the....... Am I missing something?

gxl90rx7 10-07-07 08:54 PM

I was there, that little fucker wouldnt come out for the life of us. we drilled a hole straight through the part of the sleeve that was showing and put a large bolt through it to hammer it out and it wouldnt budge. we tried PB blaster too with no help. he eventually got pissed and just started bashing teh hell out of it with a screwdriver and if finally let go LOL

Alot of the time a camera flash will make irons look alot more worn than they are.

The only way to tell is with a gauge setup, or at least a machinist's straight edge and feeler gauges.
