Check your nuts! Reminder.

Postby battleshaft » Thu Sep 07, 2017 7:05 pm

Hello All,

Most of you will already be aware of this as a common occurrence but I thought I'd share.

These are the two most serious of the fixings that I have found to be loose (upon first check):

Front Sprocket Nut. Saved by lock washer!

Rear Sprocket bolts - 4 out of 5 were loose, 2 of which were finger tight only!

I checked my rear sprocket while I had the rear wheel out for a pre track-day tyre change.

Just thought I'd reiterate in case anyone was in two minds about checking. CHECK THEM! If they're loose, clean adequately, apply Loctite 243 and torque them to spec.

:D

Good advice. What are the torque specs for those bolts?

The manual has torque settings Steve, well the manuals for the 1290s dose. On my 1290R (2014) on my first rear tyre change, i brought a 60mm socket, put it on my impact driver, braced myself, but it flew un done at a great rate on knots, no load on that sucker bro. Clips held it. My 1290GT was a different story, my cheep impact driver wouldn't budge it. so 2 meter pipe on my breaker bar, wife on the bike, with her foot heavily on the foot brake, and in first gear, annnnnnnnd of she came. (thank fuk).
2005 640, full system, 18 litre tank, flatside carb. 2010 Black multistrada 1200 Ohlins-with SCU. 2016 1290 GT, Remus muffler and link pipe, Rottweiler plates, and dongles.

Rear sprocket bolts: Loctite 243 + 50 Nm
Front sprocket nut: Loctite 243 + 100 Nm (Sourced this through SD.net as wasn't in manual)

Note: Do not torque the front sprocket nut with the bike in gear as you may damage the gearbox. Get a friend to sit on the bike while you torque it or sit and torque yourself.
