YES I'VE SEARCH ALL THE THREADS. Alright now I'm either a Fucktard or people are smoking crack. I've got an 06 Mastiff that's getting oil in the starter. I have pulled it and went to the local bigdog shop looking for the jackshaft seal kit that everyone talks about and they look at me like I'm crazy. Have gone to every seal and bearing place in town and am being told it doesn't need it and even if it did they don't have what it takes. I know its leaking and there is a fix for it. So if anyone out there can tell me which seal to get I would appreciate it. None of the threads show what I might need.

It's your starter not the jackshaft. Pull your starter and take it apart. You will find that the seals on the armature and selinoid don't make complete contact all the way around. Also, newer versions have a dremaled notch in the case to allow what oil gets in there to drain back to the primary. Fix it yourself like I did. You get a new starter and it'll just have the same oring seals in it that don't seal.

Or wait till Kaptiian America and I start doing starter re-builds on here for all of you.

Here are the two seals that are too smalll and don't really seal. I increased the size of them and sealed it up so oil doesn't get into the armeture or selenoid



Carving out a drain grove that newer starters have


This is the most important o-ring you want to replace


This picture is not good enough but the oring doesn't even seal 50% around the case so this is the one you want to increase


Also, when this bearing goes into the case it just spins. The wear marks were obvious on the case so using some bearing Loctite (green) we sealed in the bearing so it worked the way it was supposed to work


Sealing up all those drain holes that cause all the oil to leak on your bike


My starter is locked down tight now and after buying a re-manufactured one from Shovelheadkicker on ebay we took them both apart and after cleaning them up (the re-built one looked like shit) we assembled a rock proof on that has been going strong in my bike now.

Sealing it up tight. Nothing coming in or going out




Two different casings. Seal those holes


The holes are there to drain out what gets in. Once you seal it up like I said nothing will get in so seal up the holes


Here is a pic of the two armatures. Believe it or not but the dirty one came out of the re-built starter


Locking it up



Just to liven things up!!! :)

And seal up all those drain holes with J-B weld that will allow water in. Once you lock it up you won't need the drain holes. The two holes in the fourth picture. My starter I removed only had one hole. My re-built starter had two.

So what yall are saying is that the seal just below the gear around the shaft doesn't matter. Seems to me thats how the oil is getting there in the first place .

Just look at where those two orings fit in and see if they are making a seal all the way around the case. You will find they are not so replace them with a size larger or until you get a seal. Remember the bearing seal is some special brown seal. Forgot the name of it but it's different and your specialty shop will have it.

That's just it I've been to them and none of them can match it up . That's why I think I'm losing my mind. Obviously someone made the dam thing . You would think I could get it replaced.

This seal is the one that I am having trouble with. I have replace mine twice and its leaking again.

Ray,
What did you do different with this seal?

I have found a different starter and ordered one. Will let everyone know how it works out.

Yeah happy friday.....Just picked up my starter from my local shop and this is what they handed me. It was just rebuilt by Spyke 3 weeks ago. WTF.....Also the bearing number that is in there is
C&S
6004RS It is a brown seal bearing. I put a call into spyke to find out what they put in.

I got 23K out of the remanufactured starter that was in the bike when I bought it off the floor. I will try to buy one off shovelheadkicker on ebay or bdm performance ($375). I don't mind shelling out money when needed but it sucks when you don't even know if it will work.
