starter pinion gear

Anyone know if the Jackshaft pinion gear is supposed to be beveled on both sides of the teeth(that go into ring gear for starting),trying to figure out if that is normal or maybe causing my WHIZZZZZ.It's Starting to get a little embarrassing,always when someone is checking the bike out,,never fails

Ok thanks,,although my cuts are not as clean as those,,that answers my question...back to scratching my F'n head..
 
I assume when you say "whiz" you mean its not engaging with the ring gear.
I've found, in many cases on LSDs, that it has to do with excessive spacing between the ring gear and the pinion.
I've generally been able to resolve it with a shim or by changing to a solid jack shaft to make spacing easier.

That's an interesting take,,how would one add a spacer to the pinion side of the equation?,,can I run this by you?,the inner section of the jackshaft(inside the starter,where the plunger plunges into)there is a ball bearing(I assume that's where it fell out of anyway),,would doubiling the ball bearing force the pinion gear out a little farther?,,or am I smoking too much funny stuff(probably the case)?
Thanks
 
Between 9 and 10. It usually only needs a 1/16" or so but it varys.
The idea is to push the entire assembly out to get the pinion gear a little closer to the ring gear.
Needs to be around .075 - .125.
I would do Svens technique first as the LSDs have a little play in them and it can frequently be just an alignment issue..

Say the theory to abstract goes something like this:
1. I want whatever covers off to see the ring gear and starter gear mesh.
2. I want my neg cable off the battery and my armature cover off the starter end call it.
3. I want [this time] have my starter motor bolts loose enough so the armature shaft is free floating.
4. I want to measure my cover to shaft and note if my throw needs shimming, I've already tightened my motor so the static X to Y at the starter to ring... is smooth insert no matter where I spin the ring gear, she slides in, slides out.

Shim City Special = X:
Say I can't move the beauty cover over to the inner primary, the starter shaft is the problem:
A. I can cut a pattern out of cray paper and build a shim(s) from there until the outer cover flushes.
B. I can cut aluminum sheet with sheers.
C. I can cut a check at a machine shop and pay thru the nose, but it's trick none the less.

Slot My Jaw = Y:
i. I moved my motor back in the X position so the cover is on, but the tooth drags off ring gear.
ii. I slot my motor [hole(s)] blocks with a rat-tail file so the starter gear is still deep in the ring tooth.
iii. I am here at Z is my cover is on and my tooth pattern smacks in the middle I use a marker pen and wipe some teeth.

#4 = This puppy is going to send itself into the outer cover so I can:
A. Push the outer and move the motor, I have no motor bolts in place. Did I move away motor wise.
B. I can place my left hand over the outer cover, motor is held with right hand, now I shift both back and forth.
C. I now extend the shaft #5 at its full extension, I have to hold that shaft out so #4 is sent in all the way is that shimming process so motor and cover are dealing with that #5's full thrown distance.

Make sense who is move1 X to Y and who is move2 in the X to Y line up of shaft and tooth playbook? Meaning, I need to move ring to tooth is in or out and my cover goes on and homes itself or not I pull the motor back.

Ok,,I've either got to put the bong down or spark it up more,,,I'll read what Sven wrote another 4times till it makes sense,,,no fault of his,he knows what he's talking about,,thanks Curtis for the cliff notes
 
LOLOLOLOL...Sven always has a great multi line story.
Move this, push that, slide this.
The bottom line is if you work with the alignment and you still have the problem then you need to get the pinion gear/ring gear air space thinner. Or you can just buy a better starter that is stronger and be done with the issue.

I prolly fkd it all up, but I just flipped the ring gear and gave myself a brand new surface(so to speak) for the pinion gear to engage....jmo. No problem since.....

That was a cheap fix, I just replaced my starter ring gear also but it was part of the clutch assembly for the right side drive, I couldn't flip it

I think the starter is an All Balls(just posted a picture I took after taking it apart),I'm going to guess the douche bag who sold it to me and installed it,put in a used one at a new one price...I don't think it's an alignment issue because the original never had an issue,and jacks haft or any other inner workings were never changed

Don't get it,after taking my 2.0kw apart,inspecting everything,replaced missing bearing,,put it all back together,ground down a small burr on the face plate(thought that may be cocking the starter a little,felt really good thinking if fixed it.....F'ing NOPE!!!!,it's def. not internal,everything lines up perfectly when installed,,,can't for the life of me figure out this F'n whizzz,,,there's no rhyme or reason,the pinion gear just intermittanly misses..Major PIA,,any other thoughts?,,would it be worth it having the origional 1.4kw rebuilt(never whizzed)?,Idon't want to spend another $300 on a new starter to have the same results..
