RSP Sector shaft brace help!

Hey guys:

I got a RSP sector shaft from a member a while ago, with one issue. The seal that holds the grease had went missing in the process, obviously this should of been an easy fix if the company had not went out of business. In addition to that, the company that made the seal for whatever reason ceased production of this one size. So after looking for other companies that had something compatible, I am doing something I should have done long ago and asked anyone on here if they had this seal or any extras laying around because i know they were only sold in like sets of six or something like that.

The seal is called a heim joint rod end seal and was made by "Seals-it", as Im already sure one would know if they had them laying around but I thought I would include that anyway. The size that is needed and that they stopped producing is 7/8". I would like to throw this brace on, but I have nothing to hold the grease in. If any of you have any of these around or even an alternative that would suffice for my needs that would be greatly appreciated! Thanks!

Also: This link below displays the seal itself in a couple of the pictures if you're not entirely clear on what Im looking for and actually have the brace around. Thanks!

Good news, maybe...
I hadn't installed my RSP unit yet (don't ask ) and decided to check it out...my seal is either the 25mm or 1".
The boot covers all the way out to the orange and there's enough "washer" to be engaged by the nut, tho' there may be some "centering" of the seal called for when tightening it up to keep it concentric.
The 7/8" seal's boot, according to the specs, would leave 1/10" of the bearing race exposed but likely doesn't need any attention to centering upon install.
I'd rather have the race completely covered, that's not a part I think I'm gonna find if/when it gets corroded, even if it means paying a little more attention to the install.
I didn't check the torque for the nut...that could be an issue if it's relatively high, possible squishing the washer out. I'm gonna check the instructions.

So, if I'm understanding this correctly you're saying I can order the 1'' and get away with it?

Okay. 185ft/lbs. The coverage of the washer looks enough. However, another issue reared it's head. If the nut seats all the way into the race, the seal gets inverted. It still provides coverage but I'm thinkin' a cup would be better than a cone that inverts.
Gonna look for a cupped option, like a motorcycle steering stem bearing seal, just in case...needs to be 42-51mm in diameter.

The 7/8" seal fits the shaft but the nut may interfere with the rubber boot...could be why yours tore.
The 1" seal has the boot sitting almost completely over the nut, almost centers itself, and the washer covers enough of the nut that I'm okay with it.
I don't know if you had the issue of the boot inverting its cone when the the nut gets installed into the bearing, but I'm looking into a remedy.

I dont think the boot ever tore. We just were unable to locate it, after he took it off he had it sitting around for a while and then couldnt find the boot before giving it to me.

Oh. Well that changes things. I thought I read somewhere that someone had torn their boot...thought it was you.
So, if I have a 1" seal, maybe that's what they came with. ?
Still gonna look for another option.

Im pretty sure there was 5 different versions so I wonder if they changed it over time, do you happen to know which one you ended up with?

BTW: only took me 5 years to get to 100 posts in here!!

Instructions say 5.0 but, after a few phone calls about making one for me, I'm sure I got his latest version, 5.1.
This was some time ago...I'm in that other thread.

Just an FYI, this will be installed with a MetalCloak trackbar and, eventually, with high-steer Reids. Neither have been installed, along with all the other MC stuff. I'm slackin'...big time.

I can take pics of the RSP. If you want anything specific, let me know.

Ok, but you're confident you have the 1" seal? if so i may just order some of those.

Measured it with a caliper...1.010" or 25.6*mm.

Waiting on a reply from a bearing/seal MFG now for a more appropriate seal.
The supplied joint seal is designed to wrap around a sphere, but it does appear to be capable of the task if the gap on the OD is also full of grease. I'd just rather have a proper fitting seal, like this...

Oh, yeah. It's the correct type of seal for this application...assuming the nut sits all the way into the bearing and we can find a usable size.

I've heard from the seal distributor, but I'm pullin' teeth.

Will update when I hear back...

I found a seal...ID25mm, OD47mm. I'm gonna order it. The 47mm OD will put the seal right in the middle of the outer race.

I won't be installing mine for some time yet and, of course, I don't have the seal yet...no pics.
If the seal doesn't sit flush with the race after install, you should be able to give it a bit of a convex shape by supporting the OD on a big socket as you push on the ID with a smaller socket or ball. Conversely, if it's too tight on the race, you can put a concave shape to it using the same method.
At $1.80 a piece, I'll prolly order two.

They shared some of their database with me and I can't get it to load here, but here are the narrowed down choices.

Part# ID OD Thickness
33-1001 26mm 47mm 3.5mm (This one seems the least desirable.)
33-1023 26.5mm 52mm 3.5mm (This one will have the OD riding on the orange part of the bracket by .5mm, or on the seam between the bracket and race which might tear the seal up if the bracket's not smooth. Either way, it will ensure the bare steel of the race is always covered. I don't like the ID, tho'...might not sit concentrically.)
33-1024 26mm 48mm 5mm (This one's kinda tall. If the nut doesn't sit completely in the race, it might be a consideration.)
33-1025 25mm 47mm 3mm (I'm gamblin' on this to be the one...low and concentrically tight.)

Given the prices, I think they're all $1.80, I might just buy a 1023 and 1024, also, now that I think about it.

Stuff to think about and, if you have the access to the shaft, something to measure...
The outer race of the bracket's bearing has an ID of 42mm and an OD of 51mm.
The nut's thread ID is 20.4mm. Take into account the threads on the shaft will likely add ~1.5mm and we're at 22mm.
How big does the shaft get before stepping up to the splines? This is where the seal will sit. I'm guessin' around 24mm.

The heim seal provided by RSP was prolly a leftover from previous versions where, from internet pics, it looks like the nut sat higher than the bearing housing. I can totally see using the heim seal in those applications.
