Having at my swing arm bearings for cleaning, inspection and lube (or possibly renewal) this weekend.
When reassembling*, is loctite on the pivot pins needed? If so, which one (loctite) do people use?
Cheers
*this of course assumes I can get the SA off in the first place!

No loctite needed, or recommended  . |

Get that loctite on. You'll need the "loctite 270"
If your having trouble removing them use a little heat gun or a gentle flame to soften the old thread lock.

I have an official Yamaha service manual for the XJ600 and no loctite type substance is suggested for that. It is very unlikely Yamaha would suggest it for the 900 but not the 600. If you want some "unscheduled excitement" may I suggest hiring an SUV and going for a drive in New York |

If you put loctite on there's nothing more you can do. Your eliminating the risk of it falling off. just because you like cutting corners no need for anyone else to. There's always a first, and the sate of some of your recent bikes........ |

I have never claimed to be a mechanic, so it would be difficult to give up something I am not! I just wondered why Yamaha fitted them, if they were no good at locking the nuts! |

You should be asking why Yamaha used a thread lock........

Make your mind up...... my mind is made up, it's your mind having the problem, the lock nuts work fine, the thread lock is to seal the threads from moisture, in much the same way as using copper ease, except thread lock won't get washed out, and it's another level of security for the pin, which is an advantage to a manufacturer over using copper ease! |

Of course...... |

The Yamaha repair manual for the 900 implies no need for threadlock, just torque up the bolts. I've also reinstalled the swingarm bolts a few times without threadlock and it's been no problem:  |

I have met him once or twice although I think Trevor knows him better [/quote] Brewers Whoop is the result of a tasting of homebrew that has turned out well. A cousin once removed of brewers droop, I believe..... When I got the SA off, found one pin (the left) loctited, the other not. Which sort of matched divided opinion here! The left (loctited) side bearing was fine, the right was knackered. Wonder if this was due to the right hand one having never been changed due to the level of PITA-ness in getting the race out, or the absence of loctite. Anyway, thanks for advice all. |

I didn't use threadlock on the suspension linkage bolts because its almost impossible to properly degrease the threads. I never had any sign of anything coming loose. Anyone really worried could drill the nuts and wire lock them.
Both of my swing arm bearings were dry and knotchy. The frame around the top shock mount was paint-free and rusty.
