This is the Napa 1324. This is also the "tube connecting", that i ordered directly from bobcat. I thought it would fit the Napa filter, but it's exactly the same as the one on the tractor.
It can't be a coincidence that i ordered both the "tube connecting" and the bobcat 6696286 filter, and they match up exactly, and are exactly what's on my tractor.
The only thing i can think of is that maybe Napa assumed the Kioti was the same as the bobcat and used that as the reference. Maybe some bobcat's use the Kioti stuff, and some the bobcat.

What is the measurement on the other end of that adaptor. Perhaps that is the end that goes in the block.
What is the ID measurement of the bobcat filter.
The bobcat filter you claim you got that fits, is listed at 20mm threads. Exact same as the Napa.
Do you have a picture of the bobcat filter beside the Napa one?
I guess what I am getting at is:
1. We know the Napa filter is 20mm threads
2. The bobcat filter is listed the same.
3. Both should work.
4. You claim the Napa filter is different. Actually, the Napa matches specs exact, so technically you are claiming the bobcat has threads smaller than listed.
You aren't doing a very good job trying to convince.anyone. IE, you are only telling one side of the story.
1. Take a picture of your calipers on The threaded adapfer ON THE BLOCK.
2. Take a picture of the filter threads side by side.
3. Take a picture of your calipers measuring the thread ID of both filters.
Only taking pictures of the Napa filter and showing that it has 20mm threads like it is supposed to does nothing to help figure anything out.

You really don't believe me. I'm not sure it's worth trying harder. I'm not trying to prove you wrong. Just trying to put this info out there, because i've learned from other people's experiences on this forum.
The adapter on the tractor is identical to the one i show in the photo. I threaded the new filter onto it (fit perfect), then i put the new filter on the tractor, where it filters now. It fits perfect, and matches the filter i took off the tractor exactly. I'm not pulling it off.
Where are you seeing the specs for the bobcat filter? The Napa site?
All i'm suggesting is that Napa has an error in their cross reference for the bobcat filter. I'll get my filters from Bobcat. No big deal.
Maybe someone else will benefit from this info, if they come across this problem. Hopefully it helps them.

I am not saying I don't believe you.
I am saying it is hard for anyone to believe what you are saying without proof.
What you are claiming is opposite of all the info I can find online. And opposite of what many of the bobcat and kioti owners here are saying as well.
With no one else claiming to have the same issues, on this website or elsewhere on the web....and with the many many tractors sold with that engine...show us some proof. I don't have a dog on the fight as I don't own a bobcat or kioti. My only interest is getting to the bottom of the issue and getting the facts out there.

Not wanting to cause a riff either but just an obseration. Looking at both the Bobcat CT235 and Kioti CK35 on line parts list the pictures both indicate the large end of that adapter is where the filter screws on. May be a bad drawing but that is what it looks like. Would be interested to know the size of the large end?

I should have taken a photo of that too. The big end drops right into the NAPA filter too. It's too small for the Napa filter.

I just find it odd that
1. EVERY filter cross reference I have seen (fram, napa, wix, etc) crosses that number to a filter with 20mm thread.
2. Every aftermarket filter lookup "by machine" lists a filter with 20mm thread same as the cross reference
3. several other members here use a wix or napa filter with 20mm thread on the same machine
4. there are no other cases of a 20mm filter being the wrong size anywhere on TBN or google searching
5. You didnt measure the bobcat filter OR the napa filter like requested. I am not asking you to take it off, measure the old one
6. You are measuring the small end of the adapter and not the big end.
It could be as simple as the big end of the adapter, and the old bobcat filter as well as the new are both 20mm threads as they should be. And maybe you just got a single bad NAPA filter that had the wrong end put on and slipped past QC? But we arent gonna know any of this without some measurements.
I am curious (and I am sure others are too) as to why the filter dont fit that by all accounts is supposed to. "we" being behind a computer screen have no way of getting closure on this without some effort on your part. Dont leave is hanging.

i will measure the old one. I'll dig it out of the trash.
I agree. I'm freaked out by this too.
The FIRST thing i did when the Napa filter didn't fit, was go to the parts store that sells Wix. I assumed Napa gave me the wrong one. I had gone to a Napa while out of town on business, so i couldn't easily go back to that same one.
I brought in the Napa and Bobcat filters. The parts guy measured both. He pulled the correct Wix, and it matched the NAPA exactly (Confirming the Napa wasn't a foul up). He dug through his books for the better part of a half hour trying to figure out what the old filter was, but couldn't. The threads measured around 18mm on the filter. Could be standard threads i guess, rather then Metric.
That's when i assumed the adapter was changed. So i ordered one. For the **** of it, i ordered the filter too, just because i figured i may have gotten dirt in the NAPA one while screwing around.
The adapter is on correctly, and i measured the correct side. And as i mentioned, BOTH ends of the adapter drop right into the Napa filter. BOTH ends are too small for the 20x1.5 filter threads. That can't be the problem.
I will dig the old one out of the trash and post more photos with measurements. I may even pull the new filter and adapter off the tractor, although, it will be a massive waste of time.
Someone have a Bobcat dealer close by? Go buy a filter and measure it. I don't have one nearby. The closest one is 30 minutes, and is open 7:30 to 4, while i'm at work.

I know this dont help, but I found a few sources online that indicate donaldson makes bobcat filters. (dont know if thats true or not)
So, I crossrefrenced the bobcat 6696286 filter to donaldson. Shows up as a P550935. Which is 20mmx1.5 thread as well. Listed in the specs it shows primary application being a bobcat 6632745, which crosses to a napa 1381. ALSO a 20mm thread. which specs the same but is about 1" shorter but same diameter, micron, and flow ratings.
I have said it before, but IMO there are WAY too many filters out there. There are only a handful of thread sizes and gasket sizes. Sure there are some flow, micron rating, and other differences. So we do need quite a selection of filters. BUT, in the 20mm thread with this sized diameter and gasket, I bet there are 10 different filters with all identical specs, starting at about 3" height and going up in 1/2" increments.
Then take the same specs and threads and gasket size, but increase the diameter by 1/2", and add another 10 filters going up in height in 1/2" increments.
When I get filters, I like to put the largest one on that I can get to fit. Heck, I run a full quart-sized on my little kubota. Fram XG8a to be exact.
I hope we can get to the bottom of this...
