Default primary oil in starter

2010 Utra Classic 103, stage 2.
Replaced my starter with an AllBalls starter several months ago, after the OEM failed. A week after replacing it, I noticed a fluid leak underneath and traced it to the O ring between the starter and the case. I replaced that O ring and the leak stopped..... until now... about 9 months later. I found primary oil leaking all over the top of the transmission.
Traced it again to the starter, but this time, it seems that the oil is seeping out of the starter housing...? How did it get in there? How do I stop that?

Thanks

Just a guess on my part, but....

If you look at the exploded diagram of the 2010 starter, there are TWO o-rings for the starter.

There is one between the inner primary and the starter case, #5 in the parts diagram. I suspect that one is the one you replaced already and keeps the primary fluid from leaking between the starter and the inner primary case.

There is another one in the Starter Clutch mechanism, #4 in the diagram. I believe that one keeps the primary oil from getting into the starter housing.

I would guess the #4 o-ring is damaged or missing and that's how the oil is getting into the starter housing...

That makes a lot of sense. Yes, I replaced the #5 o-ring. Loos like the next step is to open up that starter and check for that #4 0-ring. Headed to the garage right now
I'll be back.

You are right. I opened up the starter housing and found that #4 0-ring part had disintegrated. Also found that the lip of the solenoid housing that meets the starter motor housing was partially torn away. But that #4 o-ring is the culprit for the oil inside of the housing I believe.

This is an All ***** Racing starter, #80-1013. Bought it in early December, 2022. On the website its supposed to have a limited lifetime warranty. But the only way I can see to contact All *****, is thru their website email system, and I'm keeping my fingers crossed that they answer soon.

Now, another question.....
I have the OEM starter that I replaced. Can I mix the two starters to make an unbroken one? Thinking of attaching the solenoid housing of the OEM to the starter motor housing of the All *****. That would eliminate the broken housing lip issue. The OEM a still has an unbroken #4 o-ring. This is my daily transportation and every day its down, so am I.
Thoughts?

So the disintegrated #4 o-ring and the broken housing lip were on a Brand NEW All ***** Racing Starter.....???

That sucks....!!

I've read a few posts about some All ***** Wheel Bearings that were shipped with issues right out of the box.... They used to have a stellar reputation... hope they are not just another good company that has hit the skids....

I have never held, or seen an All ***** Racing Starter in person. If you believe the parts you need to use from the old starter will fit into the new All ***** Starter, then I guess they would work...

I know All ***** charges a premium price for their products. I'd be a little pissed that I bought a new starter from them, with a broken housing lip AND a disintegrated O-ring.... I would want them to send me a fully functioning new starter as that is what I paid for. I suspect if you get it back on the road with mixed parts, All ***** won't warranty their starter...

On the other hand, I know what it's like to need to get a bike back on the road.

From Sept.1978 until June1984 I had just moved to SoCal, and my only transportation was my 1978 Harley FXS. That is until it got stolen in 3/1980 and I replaced it with a new 1980 Harley FXS... I'm embarrassed to admit I took more than a few short cuts to keep those bikes on the road, as they were my only transportation... Back then there was no such thing as an overnight repair.. Everything was started and finished in one day..!

Good luck and keep us posted with both how you get it back on the road, and what All ***** says about how they shipped a broken starter, and what they did to make it right...

That's a faulty casting to break like that, they don't just let go suddenly without some serious mishandling or bad alignment abuse.
