Re: Noise on take off 700 1990

posted by  someone claiming to be steve mahnken on  Thu Sep 27 07:49 CST 2001 [RELATED]

Hi, this is a common problem on the 700 series. It is caused by the center bearing support on the drive shaft. The bearing is rubber mounted and softens with age. This tends to be worse when you load the rear axle because it changes the angle between the drive shaft and the propeller shaft (tends to straighten it out). There is a solution invloving putting spacers between the bearing pillow block and the chassis to increase the relative angle between the shafts. Check archives for center bearing support and you should find the actual instructions.

good luck
