if the piolet bearing is bad, could it cause the clutch area ,and trans to vibrate and chatter. i put in a new clutch a trans wit low miles ,and a drive shaft . and its still vibrateing while trying to reach higher rpms , the timing still needs to be done also its good right now but breaks up a bit up high, and low still but is driveable. any help is most thankfull.

 

get the timing done first of all, bad timing can cause wierd vibrations.

 

Does it vibrate while revving in Neutral?

 

it does a little. it was doing this wit the old motor i had in the car before the motor blew , and that motor was fine as far as the timing was concerned , with the old motor i changed the throw out bearing but it still made the vibration up high everynow and then , so im guessing it is the piolet bearing

 

If you changed engines, then you changed pilot bearings as well since the pilot lives in the end of the eccentric.

 

no we never changed piolet bearings the piolet bearing in the motor is from the car we took it out of ,so thats why it is most likely the culprit.

 

so, you swapped pilot bearings? From the bad motor to the new one?

I would be more apt to blame bad mounts (engine, tranny, etc) then a pilot bearing. But swapping pilot bearings isnt what I consider to be the smartest idea. chances are, its damaged, just from the swap.

we never swaped piolt bearings , we just ripped the engine out put it my car and put on new clutch etc . we left the pilot bearing the way it was from the motor we pulled so we dont know if it was bad to begin wit
