B7100 (none HST) Seized hydraulic filter nut, and broken gear

[newshb_k]

Hi all

Hope all is doing well and having amazing year start

I have some noise when do I g reverse in my B7100 (non HST), and expected some worn gear in the gear box

today was my first attempt ever in tractor split, all went well except I was unable to remove the hydraulic filter (bottom of gear box), seems the nut is stripped; any ideas to help in removal?

also, I removed the gearbox cover, and based on initial inspection, I saw torn gear; as in the picture, any body knows part number ?

thx a lot

I assume that you are in the country Jordan, not in the USA. So you can’t access the illustrated parts list at Kubota USA, but perhaps there is a website that Kubota has for your geographical region. You may be able to see Messicks illustrated parts lists to locate the part number.

As far as the stripped bolt(?), you can try to grab it with pliers and pull it as you turn it to get it out.

Post a picture of the problem and more ideas will be posted.

Thanks for the reply. I can ship from USA or other country, am not sure about the part number

tomorrow will have picture for the stripped filter nut

I 'think' these may be the tranny gears ( from Canada website B7100...)
If so, pick a picture and number for the gear and I'll see what part number it is.....
I suspect the 'gurus of gears' will KNOW without looking !!

To give you a proper answer need the serial number.

Sure

tomorrow once I complete the stripping, but I believe it is the same gear Marty changed in his gearbox restoration video in YouTube

There are three gear possibilities depending on serial number.

Think a guy can still buy that from Kubota? You might need to order it from a bone yard? A little voice speaks to me that you're gonna find other problems so best to tear it down completely and start making up your shopping list.

On your filter/strainer is the hex stripped or are the case threads messed up?

yeah, I will tear it down completely to inspect everything

for the filter/strainer, it is the hex stripped

Now I am confused about what is wrong….
1) The bolt threads (male) are bad
2) The case threads (female) are bad
3) The corners on the hex head of the bolt or nut are rounded off.

I am guessing you meant 1 or 2 in the original post.
I am guessing you meant 3 in the post above.

Please clarify what the problem is with the pictures when you post them.

Pretty sure its #3. The first time I tried to get the strainer off I didn't have a metric that big so I tried the monkey wrench. It would've done the same. But I ended up buying a large socket at NAPA. It's kind of a weird size that you'd probably never use otherwise.

Use a pipe wrench to get the filter out, and buy a new one, they are not that expensive.

The old gear box B7100 as the OP pictured just has a strainer screen with a big 26mm (or so) head. Between the case and the hex is a big banjo fitting where the UTF is the suction side of the hyd pump on the side of the engine. There is no spin on or cartridge filter.

The S/N of the tractor is B7001-71659

I believe the hex size is 26;

Thank you for the clarification on the hex head being rounded off. I figured that’s what the problem was after looking at illustrated parts lists for your tractor and seeing how the strainer is actually also the banjo bolt.

First off I would order a new strainer and the sealing washers for your tractor with the plan to replace the current damaged one. That way you won’t have trouble in the future.

The current hex on the strainer looks pretty well non existent so the use of the proper size 6 point socket will probably never work. But you should get the proper size 6 point socket (or box end wrench) for installation and future removal.

Here are the processes that I would suggest you try to remove the existing strainer:
Pipe wrench if you have a good one.
Very good channel lock pliers that are designed for nut or round object removal.
Very good vice grip pliers (if the hex head is tall enough)

Then if it is still not loose then move onto more significant attempts that may require welding.

Weld an un-plated hex nut to the head on the top of the strainer nut using the inner diameter of the nut. Use a 6 point socket on the new nut.

Weld a flat bar to the hex head of the strainer using a round hole in the bar. Maybe the hole large enough to fit over the strainer head and weld it all around. The flat bar should be long enough to use to turn the strainer, maybe with the hole at the center of the length if there is room for that.

GOOD LUCK

this...from RK... Weld an un-plated hex nut to the head on the top of the strainer nut using the inner diameter of the nut. Use a 6 point socket on the new nut.
is probably the best solution.
there doesn't appear to be enough 'width' of the chewed up 'nut' to grab really good.maybe new vice grips but a long shot.
weld a nut on, let it cool, 'crack' it a bit, it should come off

probably need 2 new seals #030
