Ridetech Spindle Machined Wrong?

[exwestracer]

Hub seals may or may not have a flange because the stop may be machined into the hub. It might be the wrong shape seal lip (???), but it's pointed the right direction.

I noticed that the original seal from Wilwood was angled and even on a description on O'Reilly's website that it said angled as well. It's angled back in towards the hub. I wonder if they make a seal that isn't angled and if that would give me that much more of a seal on the spindle side to get past the bevel to the flat part? I went in with a mirror and the race is seated all the way I believe. There is no lip that it sits next to though. My only problem is that it fit and sealed fine on the stock spindle that basically had no bevel on the edge of the large diameter of the spindle. The ridetech's have a huge bevel and it's not sealing. But ridetech said all of theirs are like that and they said they put a wilwood disc brake on my spindle with no problem?

Here's a diagram of a typical Wilwood hub


The bearing race is the blue piece. Note the lip machined into the hub behind the race. If you couldn't see/feel a gap in there, then the race is probably seated. If there was a space there from a burr, debris, or whatever; the bearing would ride too far out of the hub and too close to the the seal lip. They are all CNC'd, so you may have got some that accidentally weren't bored deep enough for the bearing???

I understand that the 2 spindles are machined slightly differently and that the hub does seal on your old spindle. I can only keep saying: the...seal...should...not...be...that...close...to ...the...edge...

It could also be a design issue. Wilwood may have cut the seal depth tolerance close on a stock spindle to save a little weight. I know ridetech said their set fit fine, but that was a different person looking at a different set.

Did you double check that the bearing installs all the way up to the face of the spindle boss?

Here are some pictures that I took this afternoon. It is a hodge podge worth of stuff. The spindles in the picture are the stock factory spindles as I have not received the ridetech spindles back from them yet. The measurements from the inside of the inner race to outside of the hub measured 7/8". The inner race was bottomed out as you can see in ther picture. From the outside of the race to the outside of the hub was around 3/8". From the back of the bearing seated in the race to the outside of the hub is 1/4". Let me know what you think. Thanks!

Picture #1,2 &3….shows the seal with the “open” side turned outward from the hub. Plenty of seal surface this way, but according to the instructions , the open side goes inward.



Picture #4 & #5…. shows how the seal would be contacting the spindle IF there was no chamfer on the ridetech spindle, the seal surface contact is complete. Add the chamfer and the seal would be riding on the chamfer edge compromising the seal surface.

(The seal is ¼’’ thick and was positioned flush, where the bearing would seat against the spindle shoulder.)



Picture #6…. Simply shows both sides of the seal



Picture #7….with the bearing & race seated fully in the bore, the seal pressed in correctly in its bore, the measurement is ¼’’.



Picture #8…. confirms race has bottomed out in the bore.



Pic #17…. shows another angle of the seal on the stock spindle with the “open” side out.



Pic #19…. with grease applied to the seal lip, the hub with the bearings and seal was installed on the stock spindle and then removed. You can see, by the grease mark that was left, if the chamfer was not cut on the ridetech spindles the seal would have plenty of surface area to seal. With the chamfer there is no place except on the “corner” of the that chamfer for the seal to ride.

We also did check to see if the bearing goes all the way up to the spindle. It did. Thanks guys for all your help!

You really should check that on the ridetech spindles when you get them back. That's where the problem was after all.

Do you have a set of stock hubs?

If so, check the dimensions shown in this picture against a stock one.

Here is a comparison of just your stock and ridetech spindles (your photos, cropped) for everyone to look at. I'm still of the opinion that the seal should be further up on the step than the difference in chamfer. It does look like the ridetech may have a slightly larger radius chamfer where the bearing rides, but not much...

Great pics in your last post BTW. The bearing races are definitely seated in the hubs...

All i can say is i had a Kore C5 brake kit on my stock spindles and i put the ridetech spindles on and put everything off my stock spindles onto the ridetech spindles, and no problems.

I talked wilwood about my brakes a while ago and they said there kits only work with stock spindals and heidts spindals. might check with wilwood. todd

Is this as far as the hub will go on the spindle? I may be wrong but if so, I don't think its all the way in.

[piratebaseball]

Yes sir, at that point there the back of the bearing is up against the spindle.

Picture #8…. confirms race has bottomed out in the bore.

It's kind of hard to tell in the pic but it looks like the front race bottomed out but the rear still has room before it bottoms out.

Hey guys just wanted to give you an update. The disc hub that they put on my spindles at ridetech turned out not being a wilwood. It was a baer hub instead. So does anybody know if wilwood discs fit on these spindles? I believe ridetech is order a hub set to test them and see what the deal is. Now that's customer service!

[piratebaseball]

Just wanted to give you an update. I got my spindles and brake hub back from ridetech today. Wilwood's brakes will not fit on the ridetech spindle and barely fit on a stock spindle and seal on the back side. Ridetech customer service was great. They really went out of their way to help me out. They sent me two new seals that'll fit to actually seal on the backside and I have to install the seals backwards. I'll get the seal numbers so if you guys run into the same thing, you'll know how to fix it. I'll also get some pics too of the install to show you. Thanks guys for all your help and to ridetech as well!

[exwestracer]

So did you figure out exactly WHAT the difference was? I'm sure there are some others out there who would like to know. Installing a grease seal backwards might fix the problem, but there's obviously a design issue somewhere...

[camrat68]

So are you saying that Wilwood brakes WILL fit on a ridetech spindle as long as you change the seal on the backside?

I'm bumping this to see if maybe the p/n for the seal can be posted. I have Wilwood brakes on my car and want to use ridetech's Tru Turn on my car in the near future.
