Hi
Im busy doing the Beisan Systems anti rattle kit on my s62, question I have is once the vanos sprocket is re assembled with the new parts, how much of resistance should the shaft have when turned? How easily or stiff should it turn? How much of play should it have?
Im a bit confused on how to gauge whats the correct 'feel' on the shaft.
Please help
This is an insert from the Beisan systems site..........

"Inspect splined shaft bearing axial play.
Hold splined shaft and rotate splined shaft stud to note resistance to rotation.
Hold splined shaft and tilt (rock) splined shaft stud to each side to note bearing axial play (free space).
Note: Axial fit cannot be properly assessed until splined shaft cover is fully tightened.
Note: Radial play, side to side movement, is normal and necessary. This should not be confused with axial play, in/out movement.

If splined shaft stud binds and is difficult to rotate then axial fit is too tight and loosening adjustment is needed.
If splined shaft stud has any tilt movement then axial play is present and tightening adjustment is needed.
Any level of resistance (pre-load), without binding, in splined shaft stud rotation indicates no axial play and is considered an optimal fit."

you should be able to rotate the stud easily and freely with no resistance. You also should not be able to push or pull the stud in or out, which is the axial play they are talking about, (that is play along the plane of the axis the stud rotates on).

If the stud can be pulled in and out, you need to remove material from the centre sleeve, if its tight remove the material from the washers.


Radial play is if you held the stud firm, and then tried to move it towards the outside diameter of the helical gear, not pulling or pushing it in or out, and any play there is normal, it cannot be adjusted.

Thanks Jamie..... I knew u would know about this stuff....


what is the tilt they talking about?

the tilt is another way of describing the in/out movement. Imagine grabbing the stud and trying to "bend" it out of the gear, you'd tilt the stud ever ever so slightly if there was any axial play as the stud wants to move slightly in and out.

I simply used in/out as an easier way for you to visualize the movement you are trying to eradicate
