The RIGHT way to remove the exhaust sleeves...pics!
 

I know that it has been covered here before, but I came across an old thread about someone asking how to remove the exhaust sleeve. I had these pics on my computer, so I figured Id post em up.


So you want to remove that crummy, restrictive exhaust diffuser eh

Heres what you need, welder and vise grips

First start out by cleaning out the roll pin with a pick or some brake cleaner to get rid of any grease or dirt. Please wait a few minutes for the brake cleaner to evaporate before welding ;)
Just tack some weld onto the roll pin and build up a nice bead, just enough to grab onto with your vise grips.

Once both are out, the sleeve shouls just pop right out

And the welding wont damage the aluminum housing any.

To re-install the sleeve just pound the roll pins back in and take a grinder and grind off the bead of weld that is sticking out.


Simple as that...no messing around with stupid wood screws or wrecking drill bits trying to drill them out.

Nice!

I just use a masonry drillbit, works wonders
New exact length pins in as they need to rest against the aluminum rotorhousing, I've had one come loose because the rollpin was not long enough and worked its way out of the sleeve.

The RIGHT way is relative my friend. I don't have a welder or welding knowledge. So thats not the right way for me. And as far as putting the pins back in and then grinding it off without touching the housing would be a feat in itself. If it weren't a sealing surface I'd say to hell with it but I think the screw method is just fine.

I dunno, personally I've never really had any trouble getting the things out with drill bits. Takes a little patience, but worked fine.

Maybe just me though.

I've done it many ways, I use my tig :) couldn't imagine trying to bother with my mig. You can reuse the pins reliably if your good at reworking them. I have done it on different applications that are far more prone to not working than the ones on the exhaust sleeves. I "remove" the weld before I put the pins back in. I have found that the tig is by far the most time saving method of every other way I tried.

right size screw or screw extractor + slide hammer

I get some credit for that??? nice pics..

I tried this long time ago and found that the weld will brake off the spring
steel, worked a couple of times but not all the time.
maybe i didnt put enough weld on to heat the pin enough?
a good tungsten drill bit cuts them out in one go taking all of 5 secs,
just can reuse the pin after.

Yeah I'm a dumb ass. I used a carbide burr and ground out the exhausts sleeve until I could drive the roll pin right through. Then I TIG welded the ground out area back up and ground it back smooth... Hey it worked thats all I know
