When do you replace a broken rotor bar?
When do you replace a broken rotor bar?
From the spectrum we can see 1x harmonic running speed with pole pass freq sideband; this indicates a rotor bar problem (broken or cracked rotor). Electric & mechanic team replaced motor on April 6th, 2016. We did re-alignment with thermal growth 0.25mm in the vertical level (motor set to +0.25 mm). Result: Vibration OK!
Is the FP sideband of a cracked rotor OK?
Result: Vibration OK! After motor changing, there is no Fp sideband appearing around 1x harmonic running speed. After the motor was dismantled, we inspected the rotor and found the rotor was cracked. He was graduated from Universitas Islam Indonesia, a well known reputable University in Indonesia.
What causes a car to make vibration when making a tight turn?
Differential vibrations are almost always caused by lack of lubrication. In some cases, this silicone oil can leak out of the coupler. When that occurs, the coupler will no longer lock and unlock properly. This causes the clutch plates to drag and bind, which makes a chatter and vibration that occurs when making tight turns. Correct LSD oil
Where did the crack in the rotor come from?
After the motor was dismantled, we inspected the rotor and found the rotor was cracked. He was graduated from Universitas Islam Indonesia, a well known reputable University in Indonesia. His background was bachelor degree of Informatics Engineering (IT).
When do you change rotors does the vibration go away?
Starts around 40/45 gets worse through about 60/65, then starts to mellow out, although it doesn’t fully go away. No pulsation or vibration when braking. Since then, I have had the wheels balanced, replaced bad control arm bushings and still have the vibration. Went in today and cleaned the wheel mating surface on the rotor hat.
Which is the best throttle body rebuild kit?
Get an exact fit for your vehicle. Notes: Complete Overhaul Kit. Compare to original Notes: OEM #E63E-EA. Compare to original Notes: OEM #E6AE-CA, DA.
When does vibration occur on a Harley Davidson?
The vibration only occurs when in gear, in neutral you can rev it to the top, release the throttle and it comes down smooth as silk. I have had the bike in 3 different Harley dealer shops and none of them know or seem to care what the problem is. If I cannot solve the problem I have to get another ride.
Why do I get vibration when I brake?
No pulsation or vibration when braking. Since then, I have had the wheels balanced, replaced bad control arm bushings and still have the vibration. Went in today and cleaned the wheel mating surface on the rotor hat. Made no difference. At this point, I am thinking I have a rotor that is not balanced.
