My friend on the forum, YukonBob, has a '68 950 loader. It's working well, except when you touch the steering, it shakes right and left erratically. We are not sure where to begin. Bob fixed a similar issue in 966 loader back in 1985, but cannot recall what he did! Anybody have any thoughts about where to begin? Thanks as always!

Hi OF,
Scans below from a 966B are basically the same setup and so may help--it is an accumulation of wear in the ball joints and other areas as outlined--wear can also be in the box itself at the signal lever that connects to the hydraulic valve where the end of the lever engages the sleeve groove and so moves the lever as the worm rises and falls as turns are made--usually this is a place of lost motion that causes slow turns.
The rose joints on said linkage rod can be worn causing lost motion also.
One scan covers turn centering and the amount of turn so it does not clash with the stops when turning.

Had several machines with bent front frame connection arm being bent due to accident damage or being forced to turn when engine not running--in this scenario the steer wheel needs to be turned to keep up with turning speed prevent loading the connection arm when outside force is used to say straighten a machine for pushing with dead engine or such.

Hope this helps.
Cheers,
Eddie B.

Thanks, Eddie B.! I'll see Bob tomorrow and we can review your scans. Really appreciated!

Hi Team,
looking for something else I found this Service Magazine article and have added the scans below.

Thank you again, Eddie B.!

funny my new to me 1970's japan built 950 has about the same problem. it's smooth and works well when doing big wide turns when moving but trying to steer fine adjustments it shakes back and forth really bad. it's going in the shop this winter for a good once over. thanks for the info and the head start on why it's shaking and banging about that's the main reason why I don't use it.
