Head bearing tool
« on: February 17, 2020, 12:48:15 AM »
Hi,

I was just wondering if anybody has a part number for the correct BMW Head bearing tool.

mine is coming loose for the second time,
I already nipped it up the first time without a tool, but seeing as it is happening again would like to make sure I torque to correctly.

thanks

Ed

I think Ed74 should whip up a batch of these while he has his bike apart and can measure for them! :164: :015: :030:

Hope BMW have not cocked up the head bearings again, on our older F series bikes it was an annual repair, always under warranty. Over the last 46 years riding I cannot remember any bike except BMWS having a head bearing issue.

 I ended up using a pin punch to turn it... it wasnt scientific but it worked.

I did notice that the top triple head stem nut wasnt torqued down properly and didnt have any thread lock.

so no it is torqued to 130Nm and has thread lock.

Procedure was to undo the bar clamps and remove the bars,
Loosen off the top steering stem nut and top fork pinch bolts
remove top clamp.
the bike was supported on a stand when i did this so the front wheel could move lock to lock.
i turned the steering full right and proceeded to gently tap the lower steering stem nut around.
About a quarter turn or so, until i could feel light resistance (factory spec is only 12Nm).
i then moved steering lock to lock and made sure it wasnt tight through the range.
then reassembled and torqued to spec.
All Ok.
was the 2nd time I did it as the first time, I didnt torque up to 130Nm or apply thread lock to the top stem nut and it vibrated loose.

sorry no video.. if I do it again, which i dont expect to, I will video it.

Hope this helps
Ed
