Tightening the Hyperstrada head stock bearings

alantomkins · Jun 5, 2016

Hi All, Has anyone tightened the headstock on their Hyperstrada?

I just got my first MOT on the bike and it was an advisory. There is a small amount of movement but I am not sure how to adjust the bearings. Anyone done this?

Adjusting the steering head bearing play
Excessive handlebar play or shaking forks in the steering head indicate that the play in the steering head bearings requires adjustment. Proceed as follows:
Loosen the clamp screw (1) that holds the steering tube to the steering head.

Slacken the clamp screws (2) securing the steering head to both fork legs.

Using a suitable wrench (A) part no. 88713.1058 tighten ring nut (3) to 30 Nm Â±5% after having applied specified grease.
Push steering head fully against ring nut (3) and tighten screw (1) to 18 Nm Â±5% and screw (2) (in the sequence (1-2-1) to 10 Nm Â±5% after having applied the specified grease on all screws.

Grease B is GREASE B - SHELL Retinax HDX2
Molybdenum disulphide grease, high mechanical stress and high temperature resistant. -good luck finding this obscurity - must be something generic out there - let us know.

It tells you that it's a moly disulfide grease. That should be fairly easy to find.

Lots of greases like that available. Some have 5% moly, some are 60% moly. More moly never hurt anyone right?

I just love how Ducati uses this obscure circular pin thing to tighten the steering bearing rather than, say, a hex.

Thanks

Thanks guys, great response. I've ordered the special tool Â£10.90.

Your help is most appreciated.

It looks nice.

Regarding the steering bearing cap, it's probably not too critical, but they also recommend the grease for most blind bolts like the ones that hold the brake calipers and front axle. That's where I wonder what grease people are using.

I found some nasty stuff, and so far no issues. One thing - use gloves.
