Thanks for getting a new post started.

Sorry for the confusion I said on the last post. I think I said you have to remove that flange. However, now that I look at it again, that is the crank flange, and it does not come off.

Here is a guide that will detail how to do this. It is on a different vehicle, but it is almost identical to your vehicle.

It looks like you still have the two bolts that come up through the pan installed so you are going to have to remove those.

The manual does not have a process on this seal so we are going to have to use this guide, but it will walk you through this except for the fact that you do not need to remove the seal and reuse the housing.

Let's run through this and let me know what questions you have.

Thanks

Hi Kenny,
Thanks again!
I am going to tackle this weekend.
Is the seal and housing pictured complete unit?
I mean the seal is part of assembly?
I don't need any other seal?

No Problem.

Yes, that is a complete assembly. I would just lightly oil the inside edge of the seal just to ensure it slides into place properly.

Let us know how it goes. Thanks for the update.

Hi, the old seal is off. I noticed the new seal assembly has a plastic piece in the back. The old seal does not
I can't see the plastic piece fitting over the crankshaft assembly.
See image.

Are you talking about the plastic part that is on the inside of the sealing part of the ring? If so, that is most likely just a protection ring and should come out.

If I am not seeing what you are talking about, can you get a closer picture of this piece? That will help us figure out what it is. Thanks

Yes, that is what I speak of.
It looks like it pulls out.
Do I use this as a tool?
I think I'm over analyzing this.
I just want to not have any leaks.
Thanks!

Yeah. That is there to protect the seal during transportation and storage.

Use you thumbs to press it out and it while holding the frame and it should pop out.

I have followed prep for crankshaft seal install.
I watched video.
I see on video they are putting a 1/8" bead of silicone on metal seal plate.
Which is slightly different from mine.
See pic.
On my crankshaft seal there is a rubber seal around the metal plate.
So, I am thinking I don't need bead of silicone?
My old seal plate only had sealant on the bottom of plate.
What do you think?

Correct. It sounds like someone just added some to ensure they slept better at night. It is not required but it will not hurt anything if you want to use it. I have found it is about 50/50 if people do or not. Basically, they want to make sure because they don't want to do it again.

I ripped edge of the gasket trying to install.
See 9 o'clock.
I used plastic putty knife and still.
I guess I will get a new one or use the old one.
This is not good.

I see now that the plastic piece stays in the seal to keep the seal retracted
So, you push the seal assembly onto crankshaft and the plastic tool pops out.
There were no instructions with this seal.
So, I finally Googled on how to do this.
After ruining the darn seal.

Totally understand. That is frustrating. Sorry, that happened but glad you got it and provided that info. It has been a while since I did one with those guides but I remember just popping it out and then oiling the seal and it slipped on no problem, but I could be wrong.
