Just a shot in the dark here, but might that be pipe thread? Grab a 3/4 and a 1 coupling at the hardware store, or just take your screen into the store and try the fittings out by hand. A few turns will tell the tale.

Pipe threads are tapered... That particular assembly probable uses straight cut threads as threads are so deep in assembly and sealing surface is gasket under "head"...

I would say that is most likely BSPP threads. Same diameter and pitch of a tapered thread but parallel instead of tapered.

What's the TPI on that? And diameter?

Went to two industrial houses. Looks like it is M28-2.0 metric or close to it. Definitely 2.0 for the pitch. They were not super helpful. Neither had a tap in stock so I ordered a M27-2.0 and a M28-2.0 from EBAY shipping from China. My dealer didn't know, thought maybe it was a proprietary thread.
I will let you know in a few weeks when the slow boat from China makes it here.

A tap isn't the best way to repair a thread.

Ideally, you use a chaser.

I prefer a one piece solid chaser. But, I see there is an adjustable one for bigger threads like you have. This would be available to you almost right away. And, it's less than $20.

Scroll down to internal screw, pipe, and conduit repairing tools.

The size is adjustable. And, they include all the different pitch dies.

Coat what ever you use with grease, to keep the metal shavings from ending up inside the housing.

Thanks Ray. That looks like the better option. I can put it in past the bad threads and back it out.

Well it's all fixed. Thanks for all the suggestions, Ray66 idea was the magic one. I had to fab the handle due to lack of space but it did the trick. I will make sure I take the tire off in the future when I remove this filter just to be safe and have a clean path to install it.
Pics of the tool are attached.

Thanks again,
Dale

Great! I think I will put that tool on my list to order.

I would leave the screen alone now. Any debris from when they made it is out now. And, there won't be any new debris until things get worn.

The screen will effectively quarantine those things in the bottom of the sump. So, there is no need to worry about it again for a long time.
