Oil seal

[tatajoe]

Attempting to replace the Stator on my 06 Mastiff. There's this leak coming from the crank. What can I do? Is it hard to replace?

 

[knothead]

Screw 2 sheet metal screws or wood screw across from each other and not deep because of the bearing....then take a set of pliers on each side and pull it out...maybe a pain and you may have to do it again but it will eventually come out

Get a replacement first so you can see the depth you are working with. You don't want to damage the area around or behind.
Wildsteedworks has the seal and spacer you need too.

Awesome, thanks you all

Ok , back to the stator, ordered one from bigdogpartsking and got one that didn't go in, the stator went in no problem but the rotor didn't. What part # and from who is anyone that needs one get it from. 06 Mastiff. They received the part back no problem and issued a refund, good guys over there.thanks in advance brothers

It is probably rubbing the aluminum inner primary like most do rub... you have to die grind the primary in that area slightly to make it clear...it doesnt take much to do it...but make sure you cover the stator and seal area covered real real good so not to get shaving in it...this is a common problem

Thanks for your reply, also the crank shaft oil seal is leaking, I understand about drilling the holes to remove it, but can it be done without removing the inner primary cover?? I see the back side of that oil seal facing me

 

[knothead]

Inner primary doesnt have to come off to do it

I use a long wallboard screw. Grind the tip to a needle, but it's a robust tip like a shallow shaft pencil tip. Hammer thru the seal, then screw it in a few turns and note the bite. Vice grip on the screw shaft and it pops out. I have an old Joe Bolger tool. You saw the instructors welded vice grip with the slide shaft welded to it? More like double L two vice grips and hammer the vertical grip.

You'll notice or I've noticed two types of center collars that seal off that shaft. The one I think can be pulled and has a straight taper off the collar. The other style [HD wise] and that year design change is a tapered collar. That style can only be removed when seal is removed. So if you are forcing it or it's this style collar, can't ding that collar when using the screw. Centering the first hit is key.

With the old seal, I could walk it up the taper well before it would stop. The new one would move up half the taper and stop. Where the old seal would practically spin on the collar, and the new one had some sealing effect to its spin. I pack seal lips with grease, be it engine, forks, or wheels.

Working on the recent wreck made me change all the seals; seeing it being an old bike, and showed its ugly face sitting exposed with the primary off and showed the same leak at the crank seal. Didn't catch the trans seal walked when it went on the side stand. Had to remove everything back off and should have videoed the trans clutch collar coming off and back on. That was some fancy [first time for me] Meguyveering with just that one horseshoe tool that did not fit behind the collar. It was how I moved the collar out so I could get the U-hook behind the collar... which I did not need once I tacked how to move the flucking thing.

Oil from stator

Hello all....been a while since I have been on here. Hope you all are well. Two years ago I had a bad motor plate bearing on my 3” BDL open primary. Took everything off and then had a severe medical issue that caused my work to abruptly stop. I fogged it, took it off my lift, and covered it. It...

Good morning, this collars come off while pulling the seal, will one of you tell me which end goes towards the bearing. Thank you

Just like your holding it goes in first...shoulder side against the bearing...put it on first... then put the seal in...lip of the seal point out toward you...

Knothead, you're the greatest!!! Thank you.

Your welcome thats what we are all here for

What in my world is wrong!!! I've ordered the stator kit twice now and I keep getting the same part, different vendors, all state Big Dog parts but the rotor won't go in. It's too big. Don't want to be a problem child but I'm at my wits end here

 

[tatajoe]

I'm not sure but I'm thinking someone mentioned to dremmel the front of the primary case. Can I.??
