Separating mixing elbow from exhaust

[Dubo]

I read several good post regarding mixing elbow. I have a yanmar 2gm20f and i would like to inspect its elbow however once I remove the two clamps it seems the exhaust hose is frozen to the elbow. None of the posts here mention any trouble breaking the exhaust hose free. Is there a method to loosening the exhaust hose? PB Blaster, heat or brute force? I'd rather not destroy the hose since it look fairly solid and is wire reinforced.

Thanks!

This is how I removed mine several years ago.

I uses some WD-40 and a large screw driver to seperate the hose from the elbow.

I run a screw driver between the hose and elbow to break it free. After, I coat the elbow with anti-seize compound before installing the hose. Make sure hose clamps are adequately tight.

There are tools for loosening hoses. Look like an ice pick with a 90 bend near the end. Try NAPA, Auto Zone or whoever you have for automotive tools

I wasn't planning on removing the elbow but that does seem to allow you to get a twist on the connection which would probably be a good thing. I will also see what that tool is about at the auto shop that Bill mentioned.

Thanks for your clues...I'm off to cut up my knuckles!

Try a hair dryer to warm up the rubber. After its warm, use a large screw driver to work the hose off.
