Swing arm Movement?

[WayneUK]

Hi
I seem to have some slight movement on one side of the swing arm, will this be the bearings?

[coffee]

Wouldn't know for certain but I wouldn't have thought any play was built in so I'd go for bearings or bushes whatever's in there.

Max 1mm of play at the end of the swingarm.  Basically if you can feel any knocking at all and the shaft is correctly torqued, your bearings are shot.  Make sure you don't confuse swingarm play with wheel bearing play.

There is a knock when I pull the swing arm to the left

How much movement at the swingarm end?  Check the swingarm pivot nut for correct torque, i.e. loosen it and re-torque it, does it still move/knock?

It's possible the bearings have become dry, due to a failed thrust/cover seal or lack of maintenance.  If you're lucky and you've caught it in time a repack of grease and the seals are ok (check if they're dry/going brittle replace) you may get away with it, but it's also very possible they're shot and you'll have to replace the bearings and thrust/covers.  You should be ok with the pivot shaft, but it's possible it's damaged too, depending how bad a going over with fine wet/dry may sort it, but if it worn by more than a few thou it's also buggered, if you use it and it's worn it will bugger the new bearings in short order.

I've ordered some new bearings, I'll have a look at the pivot shaft when I take it apart when the bearings come.
Will I be ok to take the swing arm off with the bike on the center stand?

Don't forget to check the thrust/cover seals, it's bee a while since I taken them off but I'm fairly certain there's a seal built in, if it's buggered they'll need replacing and you don't want to have to do the job again

Yes, just make sure you take off any top boxes/panniers etc and bungee/cable tie the front level also be aware with lateral pushing/pulling.    The swingarm should come out fairly easily, if you're forcing anything it's wrong stop and recheck

Thank you for the advice, not done anything like this before, looked at a few vids and diagrams looks pretty straight forward, so I'll keep you updated how things go

Will I be ok to follow these steps or will I need to do or should do anything differently as this looks like a 600?

morning WAYNE, yes that`s a 600 Fazer and a very good guide with some very useful tips...slow but sure is the way to go, if you get stuck or are unsure about anything just ask on here...let us know how you get on.

Not a bad guide 

I would add clean the whole back end first, I mean proper de-grease and jet wash the under tray, get off all the old chain lub and dirt.

Ok so having a look around while waiting for the bearings to come, in case I'd need the pivot shaft, in the guide he calling the pivot shaft wrong?He has the bush and bearing and the pivot shaft is the one that bolts the swing arm on with the bolt on?

The bush (pivot shaft/s) new/old in the picture are at the bottom, the bolt or officially named pivot shaft is above these, with a washer and nut on, it goes through the bush (pivot shaft) which is hollow.

Look here https://www.fowlersparts.co.uk/parts/417...a/rear-arm bush is No 2, pivot shaft No 5.

Yes thats what I was looking at, but he said he got a new pivot shaft No. 5 but it shows a new Bush No.2 and not a pivot shaft No.5 , which are two different items.

Taken back wheel off to have a look and it looks like the arm relay bearings ? :rolleyes

[Gnasher]

T looks like the arm relay bearings ? :rolleyes

Yep, its not the pivot shaft bearings its the arm relay bearings

[Gnasher]

Mate if the end of the swingarm is moving side to side it's not the shock relay bearing.  Now hold a minute, when you say your swingarm is moving are you meaning up and down or side to side?

Sorry yes its up and down

Gnasher will correct me where Im wrong or am bike agnostic -

But that could be the swing arm bearing, one of the bearings in the suspension linkages, or possibly even a rear wheel bearing. When you say you have up/down play how are you seeing/feeling this..? When an MOT tester checks all of the above for free-play, they stand behind the bike and put both hands on the rim of the rear wheel and gently but firmly pull upwards a few times. And as others have asked, how much free play are you seeing/feeling? If the movement is almost imperceptible, then that's most likely an MOT advisory. But back to narrowing down where the play is -

• If you haven't done so already the first thing to so is remove the rear wheel, then with the sprocket carrier and axel in-place put your knee/chest on the top of the wheel and again pully gently but firmly on the axel and check for free-play - there should be none that you can feel, if there is you should replace all the wheel bearing as you can replace just one (good pattern bearings are cheap enough now)
  
• When the rear wheel out same as before grab the ends of the swing-arm and check for free-play. If you feel any its either a linkage bearing or swing-arm bearing.
  
• Remove the suspension linkage and using the bolts that go through the roller bearing check for lateral movement, as in up/down or diagonally. If there is any movement the bearings and/or the bolts will need to be replaced. Note - I think the bearings in the linkage may need to be pressed out and new ones pressed in, but don't quote me on this.
  
• If your wheel bearings and your suspension linkage bearings are fine, then that only leave the swing arm bearings. The only test I can think that 'might' show wear is to hold both arms and try a gently but firm twisting motion. If there is any free-play then replace the bearing and check the swing-arm excel for wear.
