Question How do you install the RSR seals???

Hello,

I am trying to install the RSR seals on my rocker shafts. I can not get them to stand up to fit in the groove. Am I missing something here??? Is there an easy way to slide them in??? Also, should I put some Dow 111 on the seals?

Thanks
Rick

Pull them on the shaft and pull them PAST the groove, then sliding the seal back towards the end. As it hits the groove almost all of mine "dropped" in almost totally, a few required me pulling "out" (away from the shat) slightly. The first one took me 10 minutes, the remainder took about 20 seconds each
I don't think I'd use any 111, search for threads, several real experts recommend dry with some oil applied to the oiling hole in the rocker

rlane,

Thanks so much. I was not pushing them passed the groove. I will check on putting them in dry.

Did anyone one find a cost effective source for these little overpriced buggers? Almost $5.00 bucks apiece from our host.

I too installed mine dry and added oil to the rocker openings. I only had slight problem with one rocker arm seal but it went in after careful handling.

Absolutely coat them with silicon grease. I did that and they went in fine. No leaks.

The Dow stuff is not only a lubricant but it helps resist deterioration of o-rings. The stuff is very solvent resistant, so oil doesn't break it down. That being said, you don't want to over-do the use of it. A little bit goes a long way. Big blobs of residual Dow paste are not going to dissolve and could clug up a tiny oil passage, like a camshaft spray bar hole for instance?

I don't like lubricants here. The Dow stuff is intended for O ringed joints where the O ring is expected to move a bit back and forth . For instance, the oil return tubes, which move some with thermal changes.

Here you want the ends of the shaft to expand, creating friction against the bore to keep the shaft in place. I don't want any lube there. Maybe that is a baseless fear, since some oil always seems to get out past this metal to metal seal (and past any RSR o rings, too, on my engines) to collect grime. Comes from somewhere anyway.

I worried that these seals would add friction, making the install/remove process more diffucult. Especially if one had to replace a rocker at the track or otherwise with the motor together. However, they seem to go in about as normal.

Which also made me wonder how they were going to do much good. Perhaps expansion of the shaft ends also pinches the ring, forcing it outward? I ought to put hardware in a shaft, measure the gaps, and tighten and remeasure. I may have done this with no measureable change, but am not sure.

Now, if the gap does close some, maybe that creates a role for lubricant - allowing the ring to pinch outward more easily?

I always recommend using a little oil or DC 111 as it's easy to cut the edge of the seal as you push the shaft in. I have seen this happen as the bore edges can be sharp!

Those edges of the rocker shaft bore can cut some rubber off the rocker shaft seals when pushing the shafts in. Then the seal won't do it's job as well and may let oil leak by slowly.

I like the idea to take some 1200 grit wet or dry sand paper and using a folded up small piece over the end of your finger - smooth off the sharp edges of the rocker shaft bores just a little bit while the cam tower is off the motor so you can clean it real good afterwards.
If you don't scratch the bores doing that it won't hurt anything and should help the rocker shaft seal slide in there without catching on the previously sharp edge and damaging the rubber seal.

I just put an order in for a set of the seals with EBS. No joke, I received a tracking number from UPS in less than 20 minutes. Unreal turnaround time.
