Pointy swing arm side play.

I have still few months to think but plan is to machine bearing spacer. Then I can be sure that correct parts are contacting each other and I don't have to use any extra parts (washers).

If someone has opinion I would like to hear answer (once more, my swing arm is too narrow compared to the lenght of two bearing spacers and center spacer): if gap is 1.50mm, should I machine more/less/exactly 1.50mm away from bearing spacer? I think best is something like 1.60mm. Then there is no gap at all and as shaft is torqued up to only 15Nm it allows swing arm to move freely.

Good morning all.


I have seen quite a few SV's like with this problem. Like Davie, I tend to turn shims to overcome the issue.

I have on occasion shortened the internal spacer. If the gap is 1.5mm shorten the spacer by around 1.2mm, fit it all, & see how it is. If there's still a little play shorten it a touch more.
As Sid says, it's a bit of a faff to have to keep re-fitting the swinging arm, & torquing everything up. However, if you take too much off the spacer you will have stuffed it!
How do I know this? On one occasion, (& in a moment of cleverness). I shortened the spacer by exactly the amount of play I had measured. It was beautifully smooth with no end float when I had torqued the spindle to 15nm. However, when I torqued the spindle nut up, it was binding slightly. BUG*ER!
Fortunately, having a big Lathe, & plenty of bar stock, I was able to make a new spacer quickly. It was still a bloody pain though.


Cheers.

Thats why you load up the bearings on the bench with the spindle and a spacer or screwd-rod to test it before fitting it to the bike.

It's just Suzuki quality
Mine wasn't wear, it still had paint on the end of the bearing tube.

Just fit shims

It is no bother fitting & removing the swing arm a few times to get it right, it's only one shaft...

I think DarrenSV650S has some shims left over, PM him.

Just checked my bearings , a reassuring amount of grease but movement is a bit gritty , will see if I can get away with cleaning and regreaseing... the spacers are pretty discoloured , should I worry about it?

Also what's considered excessive play? Service book is pretty vague. When pulling the spacers in and out there's some side to side movement but nothing drastic , how much Is there supposed to be?

[yorkie_chris]

None!

[Dave20046]

Stupid manual ,why didn't it just say check there's no play then
Its marginal and only when they're pulled out a fair bit but I'll just replace them. Where's best to go?

[yorkie_chris]

How do you mean pulled out?

What you are interested in is what it feels like when all on bike and torqued up.

THe manual says pull the spacers out and see if there's excessive movement while they're half out .
Will torque it back up and check movement

[yorkie_chris]

What is excessive?

Only good thing you can do with it in bits is to rotate each bearing to see if it is smooth.

Exactly and no they're not smooth atm
Will put it back in
