Air Dryer Wrench

I am having trouble removing the air dryer cartridge as my strap wrench just doesn't have enough beef to turn the cartridge. I am using a 1 inch strap wrench with a 1/2" drive socket adapter. I am looking for a stronger setup to loosen the cartridge. I released all the air pressure before the attempt, so that is not the problem. Any ideas? The cartridge is about 7" in diameter.

The strap wrench that I use is about 2" wide and is still 1/2" drive. If it has never been replaced before, it can be a bugger.
Good luck!

Is the strap slipping? If so, try sandpaper between thestrap and filter to see if that helps. That was my problem, I couldn'd get enough of a grip on the filter without the sandpaper.

An 18"-24" breaker bar should solve the problem. Since the cartridge is upside down from normal, be sure you are going in the proper direction. These things tend to be stuck and hard to get started. Be sure to lube the new one and maybe it will be easier next time. Also try to get the strap down close to the dryer body.

Get a good wrench, one with the wide metal band instead of a cloth strap. It gives more griping area. Then use a breaker bar.

Cloth or rubber band is good for nothing in my opinion a good metal band or cup for smaller filter works put in on and pull like a !!!! If you need to put a pipe on the handle. Works every time. I carry one for every size plus a pair of filter pliers.

Heat it with a heat gun if it is where you can do so safely, then try the strap wrench again, if that does not work get a bigger hammer
