Okay thanks and do the screws go threw the washer too? I only ordered seals I don't have that washer
My question is probably dumb but I don't want to mess anything up


What washer ??
There are no washers in a seal.

Yes you just "pop" them in but they don't just fall in. You will have to tap them in with a hammer and maybe a pipe that fits on the seal. The pipe must fit past the end of the shaft.
Am I making any sense ??

The "circle spring" is actually part of that old seal.
When you get your new seals you will see what I mean.
Also I see that you pulled the whole Engine apart. I thought you were going to do this with the Engine still together.

Ok I think I see what you did there.
That is the old seal and it looks like you tried to smash it towards the bearing. It has to come out the other way.
If you turn the case so that you are looking at the bearing the seal has to go out the other way. You should be able to get a punch and reach through the big hole in the bearing and tap on the seal. It will fall out the other side.

I wanted to clean everything and I am replacing all the gaskets.
... so the metal ring won't come out the way opposite of the bearing.... so am I going to have to remove the bearing?

I'm not sure if I'm missing anything. I'm not a 250 guy. Can someone chime in here and tell us if I'm missing something ??

I'm certain that seal comes out that way because if you over pressure on your leak test you blow the seals out.
CO

Edit: You confuse me when you talk about "a washer" and then "a metal ring". Pretty sure you're talking about the seal (seals are metal ring with a rubber coating and a spring).
Hard to tell when I'm 1000 miles away and not holding parts in my hand.

Are you tapping it all the way around or are you just smashing it in one spot ??
You have to tap all over and "walk" the seal out.

I thought you were just replacing the seals also. Did not know you were slplitting the case. Looks to me like you need a seal puller.
https://www.farmandfleet.com/products/1 ... gJuKvD_BwE

Make sure you keep the bearings clean. Your case looks dirty. If any of that Debis gets in the bearing, it can damage it.

I like to clean thing up, before tearing them apart. Just males sense to me.

It appears to me that you are just kinda going for it here. I hope you have read the manual and that you have some kinda idea what you are doing.

Take your time and keep asking questions.

Did the old seal leak (blow bubbles) in your leak down test?

Another thought, and I mean this in a helpful way, is to have have the parts in hand before you tear things apart. Why? Having the new part you can see what you are dealing with. If you had the new seal you would see that there is no washer, you could see that the steel I molded into the rubber of the seal.

When you replace a seal, you should lube the new seal by putting grease in the groove of the seal. You also want to make sure you do not damage the seal when reassembling the Engine. Example if you still have the key in the crank, it could nick the seal when reassembling.

You also want to spin those bearings after you clean the cases, you should not feel and roughness and there should be not grumbling sound.

Please stop!!!!!!!!!
What do you say we Learn together. If you do the work I and others will walk you through the build.

The seal has to be replaced from the inside.
The metal you see is the inside of the seal that was covered in rubber which is now gone. These type of seal have a metal base which is covered in rubber to foam the seal.

Try this before you damage the case. Take a flat punch ( something round on the end that has a flat surface) Not a screwdriver and try tapping the seal in toward the bearing. Look for a lip on the case that the seal sets against. That will tell you that is can not be removed from the out side.

Do this and report back. Stop all other work, please.

This is a main seal. and it is the seal on the stater side of the Engine or right side case
Step 1 is to learn the lingo.
go to partzilla and look at the fl250 parts list. reference your question to this and we can follow and help.

So, your checking to see if the crankcase main seal on the right side case removes for inside or outside the case.

That is question 1. Please try what I mentioned and find out then we can move forward.

Lets look at the posted pics and see If what I say makes since.

Good job, so we know the seal has to be removed from the inside. We also know the metal you see is the seals interior core. This is an important item to remember as it will play a part in the seals install later.

Lets step back and look at how we came up with that. The parts list showed the seal and the seal size.
Part #6: 25 x 55 x 10, 25 is the inside diameter of the seal or ID, 55 is the outside diameter(OD)of the seal and the 10 is the thickness of the seal. This being in mm (millimeters). Do good in math class ? can you convert inches into mm and back to inches?

if you measure the hole "ID" that you can see in the outside of the case you will find that it is smaller than the OD of the seal. This tells you it has to go IN instead of OUT.
See, Not rocket science, I used an observation. So for the boards sake what was the ID of the case hole at the seal.

I would recommend you get a spiral note book and start taking notes. Skip a few pages and use a heading of main bearings and seals. By documenting this here and now all future fl 250 guys will be able to find and you can chime in with real world experience.

Time for an observation. Looking over what you have, what needs to be done next and a possible way to do it.
So your up.
Take some pics of both sides laid down flat and post. Then tell me what needs to be done and how your going to it. Get a good pic of the lip you observed and comment on that.

My apologies I was wrong.
I thought the seal went in from the outside. Good thing others chimed in.

I didn't know FL250 seals go in from the inside either. See I'm learning too and I'm 60.
