AL-KO Overrun Shaft Play?

[Morganic]

Whilst checking the friction pads on my AL-KO 1300 stabilizer I noticed some vertical play in the overrun shaft (bit that comes out of A frame and is attached to coupling head). How much should there be? Also noticed that greasing shaft via two nipples on top took up some of the play but after a while it returned.

Is it normal to have some vertical plat on this shaft?

there will always be a very slight amount of play, but if excessive new bushes are needed

The maximum allowable amount of vertical play on the shaft is 3mm.

Many thanks to you both for advice. Play is well within tolerance. How much grease should be put into the grease nipples? I just seem to need to keep pumping-is there a time when the assembly is full?
