Hi. Little embarresed, but here we go: Trying to remove the swing arm, to change the bearings, the pivot was stuck solid. Not a new problem for me, since I am a BSA owner too. Tried heating, oiling and brute force. Is this common? I must say I'm blushing a bit, but it won't move one mm. Christer  home.online.no/~cfolke |

I have had one such case, plenty have been hard to remove but the one instance that was a real pain we had to press the pivot shaft out in a press! The shaft and the needle rollers had made a permanent friendship..... the shaft had needle roller marks a mm or two deep ! It should slide out without too much trouble so ahhh you have a little problem...try some rostoff for a few days maybe???

Thank you.
Maybe if I heat the pivot/surronding areas first, and
then spray on some penetrating oil, and let it rest for
a few days.

Hi Christer, That can be a pain...try as has been discussed. You'll need to try to get the penetrating oil into the middle somehow...Not an easy thing...sometimes a press is the only answer. Last resort though... I have been there with a large hammer and a drift before...not on SR's but on other bikes...a real pain. Good luck... SR  |

Hi christer, if your swingarm has a grease nipple fitted,just remove the nipple and use the hole to fill it up with penetrating oil. If not drill a 3mm hole in the underside and use that. When the jobs done just fill the hole with a spot of weld and grind it back. cheers franky b.

Good advice.
If I don't have a grease nipple, I will drill a hole. Then
I will.....sorry don't know the english term.....but......
install a grease nipple, to avoid this problem in the future.
Thanks again guys.

Hi. Tried to force the pivot out with thick washers under the nut, an old socket wrench and a generously sized hammer. A few blows....and....snap....it moved......1,5mm!!! Progress! It's late in the evening here in Norway, so I will continue tomorrow. The swing arm had no grease nipple, as you probably knew already, but I will certainly fit one. So, new headbearings, swing arm bearings, new turn signals, back tire etc........added to the christmas wish list. Christer |

I had a tough job with my pivot shaft too. But the hard work pays off when you can re-install it with grease nipples at each end, and you know it'll never be a problem again!  Rgdz CL |

I had the opposite problem, my pivot shaft fell out mid corner at Eastern Creek. One end sheared and the thread and nut disappeared into the undergrowth and the shaft slid out, only just hanging in there. No problems with seizing but I think I prefer seized to falling out too easily!
Once you get it all out, if you need new parts, try eBay member Biebo (Germany), I just bought a swingarm bearing kit from him for 88 EUR and waiting for it to arrive. Compared to Yamaha prices, this is cheap! but I don't think it includes the pivot shaft and nuts. These are Yamaha parts, A$65 for the shaft and A$15 for each nut.
Anyone know a local source in Oz for the flat bearings that fit inside the swingarm thrust cover? I have tried a bearing place and apparently these are not a generic part.

I think you mean the thrust bearings...Yamaha part, make sure you're sitting down and prepared for a shock when you enquire the price. About £40 UK if memory serves!! That's each.

Part no. 93342-22205.
Not cheap - several people I know have said that. Gotta pick up some parts from my dealer tomorrow. Will check the price then, and get back to you.

Have confirmed with my local Yamaha dealer, pivot shaft thrust bearings (part no. 93342-22205) are AUD$100 - each!  They didn't believe either, that they're a generic part.  Rgdz CL |

Hi, Sit down when you price the needle bearing for the gearbox as well... SR  |
