ADA Girdle Head O-Ring Too Big

[brapperdoodle]

I’m finishing building my motor, and was about to install the cylinder head. I was installing the large o-ring on the cylinder head and it’s too long… aren’t these supposed to be an exact fit??

you need to bunch it up; take an inch or so at a time and push it together to shorten it. You stretched it out while installing.

Its cause there is too much sideways force on the o ring and its being stretched out.

 

[brapperdoodle]

That’s weird, I didn’t do anything but take it out of the plastic and start putting it in the groove.

Keep working it, you'll get it.

 

[mthomps]

You cant use any sideways force when you put it on. Just down pressure. Just start pushing backwards on it starting at the part thats not in the groove and it will eventually sit in there like it should

If I can’t get it, I’ll put it in the freezer and see if I can get it to shrink haha.

Nah you wont have to do the freezer bs. Thats a myth anyways. Had a job once where installing new o rings was constant on machines and we would all roll our eyes and bust the new guys balls if he brought up the freezer thing.

start in 4 places evenly. then 8 places evenly then 16 etc. if u work it around the groove u end up with all the excess in one corner. have to work it in evenly

I pushed outward on each side of the piece sticking out and traced the groove with my fingers all the way to the other side. Did that about 3 times and boom. Thanks dudes

I never buy the ada kit and I just buy the o ring rope for the waterjacket. Put it in there and just cut the ends to meet. One dab of 1211 to seal that spot or superglue can be used
