Well I know this has been covered but I could not understand,until now. Those things squeeze out one side then the other. Is this really what they came up with? I thought my Shovelhead pushrod tubes were funky, UH NO! My wifes 2008 sporty has a one piece plate I assume this is better? Are there alternative seals that work better? I got the black ones in an overhaul kit. 99 X1 lightning for those not following my other my build thread.

The yellow to match my frame is Duracoat gun paint, pretty sturdy stuff and temps up to 500 to 700 I was told. I have used this on weapons and it is good stuff and tuff.

HELP Please!

Use a dab of super glue I think it's the trick. If it doesn't seal first time toss it and try a new one. Buy several...

One piece is better.

sil-glyde and superglue.

I learned from Badweb that using superglue to hold the seals to the plate makes it a whole lot easier. It worked for me

Be sure you push the seal slightly into a more seated position before you glue them so they don't distort when you tighten the plates. I got it right the second time.

I put them in by starting the retaining ring with the bolt till it starts squishing the seal and make it squish out an accessible side. I then work the seal in with the side of a small pick or screwdriver as I tighten the bolt. Seems to work for me.

Collapsible tubes are the worst. The first time they are pulled up to adjust they'll all be leakin.'

I scrapped the one piece style and went back to the stockers. They are crap, but they are easier to put in at least.

Today was a better day. Thanks for the help, I got it today, only had to glue one of them. Yesterday I got a little carried away on the lube. Today I cleaned them with de-greaser and put the seal in the housing,then I lubed the first part of the tube where it gets bigger and pushed down on the housing on a flat table. Worked just fine.

Wow, call me old fashioned but (from memory) I:

* Make sure the retainer is clean and free from grease
* Put the heads on
* Put some silicon grease on the inside of the seal (not the outside)
* Push the seal 2/3 the way down the tube
* Drop the retainer down to sit on the seal
* Lube the donuts and push them onto the tube
* Push the tubes on by one carefully into the head (mechanical sympathy needed) then push the bottom inwards to be in line with the tappet
* Push the seal down (careful no lube gets on the outer of the seal) then follow it down with the retainer
* Locate retainer and tighten

I find getting the head on after the pushrod tubes more troublesome than getting the tubes on afterwards.

I did mine the way Pash describes, and yes it leaked the first time. The rockers on the older ones are a bit of a challenge as well.

I think the problem occurs when there is lube on the outside of the seal, cos it makes it easier to for it to squash out of the retainer.

I have not had a leak, but I once put some NHRS pushrod bases on once and I had lube on the outer of the seal and could see it being forced out as I pulled the base down. I had not run the engine to see it leak, but I bet it would have done. It was frustrating to have to pull the base up and wipe the seal clean and try again.

The instructions said not to get lube on the outside, I hadn't done it intentionally, but like sand, it can get everywhere

Mine would not seat correctly until a dremel was used on the upper I.D. of the retainer. Once this was clearenced it allowed the seal to properly seat.> The seals ability to seat inside of the retainer can be pre-checked on the tube.. I.E. place the seal on the tube and then slide the retainer on.> Try to seat the seal inside of the retainer.. If it will not fit then take a small amount of material out of the upper i.d... This will prevent the seal from being squished out while being torqued. +1 on the lube also.. Used a small amount of Racetech suspension grease and it did the trick.

Thanks

Super glue did the trick for me just a short time ago. Before I did the super glue trick, I just couldn't see how you could keep the seal in.

Like Pash said, I think the lube on the outside of the seal makes it too easy for the seal to squish out of the retainer.

Electrical contact cleaner is great for cleaning the retainer and the outer surface of the seal. Did some today, and they are a PITA unless you get rid of all the grease...
