How far should they be pushed in?

Do they bottom out against some thing?

Mine is about 4.5 mm in. I kinda thought it was supposed to be flush.

Install it where the other seal WASENT.

If it was bottomed, install the new one a little past flush , or vise versa.

You want the new seal to run on a virgin surface.

If you get it a good ways in.. it isnt going to pop out.

If you push it in too far (bottomed out), don't you run the risk of blocking the crank bearing lube hole?

the seal shoud be recessed about .060-.080"
I made a seal seating set I pictured in another thread somewhere, I also recess the pto side and the counter shaft seal just like oem.

yours looks like its good.
I never install my seals until the cases are loaded and assembled, but new honda cases come complete with seals in them already.

I am afraid that it is too far in. It is a new seal, just wondering if I need to remove it and install another.

looks like roosty and I posted at the same time. i like the "your good" idea. I am about twice the .080 in dimension. What is the end result of seal being too far in?

i'm certain its all good, dont do anything til tommorrow and i'll measure what i'd call max and let you know.

Ahh crap. I just did the same thing as you maddog. About 4.5 fully bottomed. I just read the manual it says flush. Maybe I need to learn to read my manual in future. Heres hoping all will be ok. Mines a new crank so surface will be fine, just a tad worried now. I watch this thread with interest and see what you blokes come up with.

It must be me but that seal, if on the stotor side , looks backwards to me?

must be an optical conclusion. It is in correct.

Speaking about seals, does anybody put anything like Yamabond on them to seal against the cases?

Having a leak down tester is important. Or you can spray the area with brake clean to kill the motor or starting fluid to raise RPM. I use brake clean or leak down test for better results.

if its in to far it may not fail a leak test untill u smoke the crank bearing from no oil to the bearing a seal is 10 bucks rip it out put a new one in if the cylinder aint on yor could try to look down the oil port and see if its partcilly pluged by the seal

the seal is .263" deep, the hole is .410"

so you can safely run it .130 deep before i'd worry about it contacting the bearing, having said that It likely wouldnt get wrecked by sitting against the bearing anyways, its sitting against the crank also right.

Its not like the pto side either where it could restrict the oil hole.

My tool I made to seat them is .100" positive, once i get the seal in there it comes back and measures .080" recess.
