I have my 900 Tre oil pump out at present, chasing down the source of Fe particles in the oil (see TNT post). Before I removed the pump, I noticed what appears to be a very large amount of sideways play in the pump drive shaft.

Once out, I measured the distance between the top of a spline, to the inside of the shaft bore. When moved from side to side, this measured from 2.15 to 2.45mm. This seems to me to be an excessive amount.

The pump is still working fine, but I wonder if anyone who has had one apart, can confirm these kinds of measurements as standard.

Perhaps someone can measure one?
