GC 2410 Suction filter threads

[DaleAP]

Anyone know what the thread size and type is on the side filter for the GC transmission? I cross threaded and need to run a chase through.
Thanks

Sorry, no... but I do know it's extremely easy to get that thing cross-threaded!

There is a way to figure it out manually using thread count and a tape measure. I have never tried it but searching how to on this should help.

Being it's possibly a meric tractor, have metric tools?.... End wrench opening will give you diameter, generally with metrics there is only 2 variation of threads per MM per given diameter, one is fine thread one is coarse thread....

And then there is these....

Sorry, searched my MF Service Manual, and my MF Parts Catalog, and the online MF Parts lookup website, and I could not find the information you are looking for.

I would try calling your MF Dealer Parts/Service and maybe they would be able to provide you with the type of threads for the Hydraulic Suction Filter.

Maybe at the last resort, Jack's Small Engine has the "Suction Pipe" part # 4265209(91 for $84, ouch...

Go to Fastenal or other hardware store with a good nut and bolt selection. Go grab some appropriate sizes metric nuts. Start trying to screw them on. Once you get to the one that fits, you know what you got.

I had to get a new suction filter as I messed up the mesh taking it out, or it was like that from the factory, and it's a fairly good sized hole. I want to say it's going to be around M16-M20 x 1.5.

I know the outer nut of the filter is 22mm (7/8" in std) if that helps. I can't recall if it was a course or fine, or what the thread count was. I would possibly contact the service dept of the nearest dealer, they should know or be able to look it up.

I feared I had done that so just cranked in in until the seal seated and said to myself that's the last time I clean that out.

If you have a small machine shop nearby, they could easily measure your screen and tell you size, and thread it its.

I'm not sure where you buy and individual chaser that size, without having to buy a whole set. Perhaps you can get the machine shop will help you out there too?

If you find a chasers that big for sale individually, please post a link.

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?

 

[DaleAP]

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.

 

[DaleAP]

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

 

[DaleAP]

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,

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.
