MF 150 steering arm remova'l

[Mike tn]

Trying to take off the steering arm that attaches to the splined shaft at the base of power steering cylinder. Got it loose but not enough clearance to drop it down over the main axle. It also appears that the splined shaft will prevent removal of the main axle member from being removed by taking out the pivot bushing.

All i want to to is install new tie rods. The tie rod screws into a female thread in the steering arm, plus there is a pin going through it tat needs to come out. Any suggestions on how to get the steering arm off?..

Thanks, mike
