Engine Vibration continues

ILL call you SCOTT

Call me what
its the tool maker in me

Well i guess i got the ball rolling.
i like the ball bearing (it seem by looking at it)do u think that the ball bearing would center the lifter and keep the lifter from moving off center and cause vibs or do we still have the small vibs at around 3000 rpms with the bearing style?
warp i thing u are wright if removing the lifter causes oil pressure drop i would not recommend doing that.

IT is puzzling that the little lifter could cause that much vibration I would think the ball bearing would keep it from vibrating or we could use a tighter bearing

i did not think that the ball bearing would fix the vibs i was just saying if the lifter was the problem then people with the bearing then there bikes would be very smooth compared to mine.
of coarse all of this is just info but it would be nice if some one would say i did this and now it is really smooth. wrecka give us one example which was nice i have not balanced my throttle bodies but i do not think that is what causes my vibs cause it runs pretty smooth until i get to 3000 rpms.

My question is how much vibration comes from the straight ct primary gears? They are much stronger, however, prone to noise and vibration.

First Helical gears are much stronger then spur (straight cut) gears in fact inside a helical gear is a spur (straight cut) gear sitting at a angle The difference in both tooth elements and gear elements is the difference between the Real Diametral Pitch and the Normal Diametral pitch. Normal being a spur gear real is once the angle of helix alters. Oh since its metrics its probably Modal Pitch but the same gear theory. All gears have a calculated back lash which is why to start the clearance in the bottom of the tooth is proportional to the tooth size as with calculated back lash. this is measured on the Pitch circle of the gear. with the large back lash eliminator on the main drive from engine to clutch the fact that the gears are floating on a film of oil except for a couple permanent ones like first and second on the input shaft and fifth gear on the output shaft I would say if there is vibration in there she lost oil and one of the bushings the gears ride on is galled up. I would say highly unlikely and if so you have major oil problems elsewhere like up at the cams. No I bet not.

Ya can you tell I used to teach machinist in my old unretired life.

warps definition of the gears is excellent i wish i could explain like warp. he has a special talent and along with the pics he is a special guy and a real benefit to this rocket site.
i will add a line although the angle cut gears makes more contact they produce more thrust while u r adding torque and in the opposite direction when u let off the throttle so when using angle cut gears u have to use thrust washers to keep the gears apart. also because of the thrust it would put a lot of pressure front or rear and the gears would tend to pop out of gear. so that is why they use straight cut gears on motor homes and large trucks. and they tend to be a little more noisier the angle cut.

Yes, Scott is a great guy and a real asset to this forum. I've read you loose a little HP through angle cut gears.
