Quick Crank Seal Question..

[mushroom_toy]

Did I go to far with it, or should I drive it in until it stops?

I've always gone till it stops. The only time that's gotten me in trouble is with the axle seals.

Until it stops. You will notice a tone/tapping difference when you reach the stopping point.

All the way in is the way to go...

I made mine flush with the block because the original one was like that, haven't had any issues.

I put mine flush with the block, that's how it's supposed to be. If you go too far you risk pushing the rear lip too far and off the surface.

[mushroom_toy]

Should I pull it out and get another one or do yall think I should leave it in there? If I pull it out thisll be the second scrap one. :(

[russiankid]

I don't remember how the crank is on A20, but any seal that I have done on an engine I have always done it flush with the block.

Better safe than sorry.

[mushroom_toy]

Damn :(

[carotman]

I pushed it all the way in on my civic and B20A Accord

No problem so far

[mushroom_toy]

Yeah I think im gonna leave it like it is and try it like that.

Just wanted to say I think your doing a good job on this one!:thumbup:

What I have done is looking at the hole where the seal sits and how the old seal was installed. If the hole has a seat I would push it all the way in until it seats.
If there is not a seat (like with axle seals) then I would look at the chamfered edge in the hole and push the seal until it is flush with the chamfer (2-3 mm pass the "flush" position)
I left one seal flush on my Civic (camshaft seal) and the next time I looked it was coming out loose

If you put grease in the inside to prevent the spring from coming loose, I would leave the seal as it is

By the way, nice job you are doing.... when are you going to start it?

[2ndGenGuy]

I don't think it matters where it sits so long as it seals against the block, and isn't riding in a groove on the crank. I am pretty sure they give you all that depth in case an old seal wears into the crank. That way you can push the new one in deeper and not have it ride on that old groove.

Thanks man this is my first engine build and unfortunately I dont have sockets long enough and no pvc around the house. XD Im hoping the seal will be fine though.

You will be fine. And you will have what you need for the next one!

my mechanic went thru 2 aftermarket seals, both of which leaked. He had to drop the tranny a total of 3 times, after I told him to only use a Honda OEM seal. Worth the couple of extra bucks.

I'll agree to this.

Important seals such as this should really be replaced with Honda OEM.

I had to take out my tranny to replace a leaky rear main(not oem) with a Honda seal, no problems since.

Good job on the rebuild.

Dammet! I guess I better head over to honda and get me a rear main seal!

[mushroom_toy]

I might pick up a honda rear main then if it isnt too much., but the crank seal is already in...and I think im gonna leave it lol.

Use the old seal to drive in the new one.

[mushroom_toy]

Old seals are long gone. (trash, didnt think this far ahead lol.)

[MessyHonda]

get a honda rear main seal...the guy who replaced mine had to drop my trans to put in a new seal...and bastard dumped all my mtf...that shit cost me alot of money if he would of put the right one in the first time
