Inner Primary Race upgrade

[JDhog211]

Hello all, I'm thinking of replacing the inner primary race and bearing with the new upgrade. Instead of the inner race being pulled and pressed on the trans shaft, the bearing is now upgraded into a sealed bearing installed into the primary housing itself.This bearing will then have a slip fit onto the transmission shaft.
I know you know the companies offering these upgraded bearings.
I would appreciate your input.
Thank you!
BTW it's my 2004 FLHT 88ci I'm referring too.

Do a search on this site for inner primary bearing race.  You should find plenty of discussions.

I think how you ride and what kind of power you use may be critical to your decision.  The S&S race is popular and foolproof.  Some have moved away from the bearing you describe (including myself this winter).   Those individuals are putting lots of power to the pavement regularly and some have experienced failures.  Again. do a search and pick up on the conversations.

Tried that back in the day. The bearings don't last. I even tried removing the seals on the bearing. Same thing, still didn't last.

The Shovel Heads used a single roller bearing in the inner primary for the transmission mainshaft. I never could get more that 15,000 to 20,000 miles from them.  I think they're a terrible idea.

Back wood move . Get the S&S race & HD outer bearing.

 I'm installing a standard race on my 2004 88ci 5 speed transmission. I have the proper install tool for this.
Do I put it on dry, or do I use a lubricant to help prevent galling.
This is a standard All Balls Race, not S&S.
Thank you!

[Dan89flstc]

The All Balls race is not a standard race.

[JDhog211]

Dan, it's standard size wise, it's not a OEM Harley Part if that's what you mean.

[smoserx1]

At least oil the shaft or the inside of the race, or both.

[JSD]

I recommend loctite retaining at main shaft as i have found the All balls walk towards seal

   you beat me to it by seconds.

Ok, I definitely got talked into the S&S inner race.
Once installed as per instructions, can it be removed if it had too by using the standard horse shoe tool?
As I understand it fully installed there will be a gap of .100 inch between the race and the end of the drive gear.
Am I right on this?
Thanks for any response.

The pic on that site ( 74629 ) sure looks like the pic belonging to S&S   

[FSG]

Yes and Yes

don't force it during installation as they can crack

[smoserx1]

As I understand it fully installed there will be a gap of .100 inch between the race and the end of the drive gear.

Below is a pic of mine when I did it.  I would say that gap was more like 0.2 inches but the race was getting so tight I was afraid to push it anymore.  I would suggest after installing the race you coat it real good with grease and then temporarily install the inner primary.  Snug up the bolts (you don;t need to torque them yet), then remove the primary.  You will be able to see how far the seal in the primary pushed the grease on the race.  As long as the grease line stops on the race you will be fine (hope that makes sense).

Yeah. But a lot LESS $$$$.   I've used many over the years.

Thanks for all your responses guys, appreciate it.

Smoserx1  My local Harley Davidson stealer Lead mechanic stated to me to install the race dry. Clean the shaft well, but press it on dry.

[Ohio HD]

I always lube them. When you press dry you may get a galled surface which reduces grip.

[JDhog211]

Ohio HD.  What kind of lube, oil, grease, Assembly Lube?
Thank you for your input, much appreciated.
The service manager stated that by lubricating it will increase the chance of walking.
Ohio, I personally can't see installing dry steel over dry steel.
What would you use?

[Ohio HD]

The optimum lube would be something made for machine shop use. But some clean light weight oil will allow it to get some relief from drag.

[Ohio HD]

Here's the S&S instruction for the race.

[JDhog211]

Ohio HD,   I saw that info for the S&S race install. I'll be using the standard OEM HD race for my 2004 FLHT 88 engine.
My original race never walked so that's why I'm replacing with the HD OEM PART.
What lube would you use now?
Thank you

I believe Ohio answered that question in post #23 after you first asked him in post #22.      I can't speak for him but I doubt you will ever see him using OEM when the S&S is sooo much better.

I would still lube it as described above. I wasn't speaking to the S&S race, I was speaking to any inner primary race.

[JDhog211]

Thank you Ohio HD. Just got off the phone with San Jose HD here in CA. and their mechanics there recommend motor oil. So that, along with your recommendation, that's what I'll do.
Thanks again.

well if you're not going to use the S&S offering then at least spot tig the OEM race so it can't walk

[JDhog211]

Hello All, I do want to thank all who responded to my post.
I ended up making the decision to go with the S&S race after all.
Pressing the race on was easy, it walked right up to its stop on the shaft, could actually feel it seat against the the stop.
Thanks for convincing me to go with the S&S.

[FSG]

    well done 

[Ohio HD]

One and done. You can check that box off as fixed for good. 

[smoserx1]

Pressing the race on was easy, it walked right up to its stop on the shaft, could actually feel it seat against the the stop.

That is the way it is supposed to go on, but it was not my experience.  The S&S race was far tighter when pressing it on than the 2 or 3 OEM races I had previously replaced.  I could not detect the stop and it finally got so tight I was afraid to go any further.  I guess mine was just on the tight side of the tolerance range.

[Hilly13]

On my old wideglide i put the race in the oven, hit the shaft with a chill spray(sorry can't remember what it was exactly now) and it went on easy as, suppose i should put one in the slim.... eventually.
