Swingarm Bearings

[Fry]

OK guys and gals, its been a long time since I logged into the site, and even more since I last worked on the GS project.

With winter coming I have renewed interest in getting the project complete, and thus have taken up where I last left off, a problem.

I need a complete set of bearings for the swing arm, and the linkage. Can anyone point me to a aftermarket source?

Also I could use a PDF file of the swingarm parts diagram.....

Thanks much, pics and updates to follow soon. Im real close to an entire mock up of the bike for final fitment before I tear it down again, yet this is holding me up....

Not a pdf, but there you go. Should be able to take the bearings to a bearing house and get standard replacement bearings, generally cheaper by far than "motorcycle parts" unless the bearings are quite non-standard. Haven't replaced mine, so I don't know for certain on this part, but in general that's true. $15 each at BB for the part #2, and $16 for part #3, which is more the shock mount than the swingarm, but on the parts page/diagram. I'd guess the other bearings in the linkage are on a different diagram.

I dont remember the exact details but if memory serve me right all 4 of the needle-rollers bearings in the swingarm and 2 of the ones in the lever are all ISO standard items and available from a bearing supplier but I think the remaining 2 in the lever along with all the hardened rollers that fit inside are only available from Suzuki as OEM parts.
best thing to do is get them out and take them to a shop, let them ID what they can, give you a price and compare it to the cost of the OEM parts.

Here are the OEM Part no's for the LINKAGE bearings that you might be able to get from local bearing suppliers:
KOYO BHKM1726JUU   -you need x1
KOYO BKM2026JUU    -you need x1
IKO 6 TA172425U303   -you need x2

I know oh sublime one, but I couldn't find the OEM numbers so thought it would be a useful post

I had to weld my bearings to shrink them out.

Its all in there 

Getting them out can be tricky, if you try drifting them out there is a chance the lips on the ends will break off making it even more difficult and at the same time its easy to damage the housings.

Best to use the correct tool.

[slipperymongoose]

Sometimes you just don't have easy access to the right tool. Welder works just as good

[sledge]

Yep......and sometimes you don't have access to a welder either  Also the possibilty of heat distortion would concern me.

[slipperymongoose]

Nuclear war concerns me as well

Nuclear war concerns me as well

Me too 

But if someone was to come in here and say to you......

"I have followed your advice to the letter and welded the swing arm bearings to get them out, but now the housings seem to have turned oval and I cant get the new ones in"....or......"I have fitted the new bearings but the pivot bolt wont line up inside them"........how concerned would you be? 

[slipperymongoose]

Unconcerned. Cause a smart person would ask how much to weld and how to do it and what to watch for. 3 small tacks was all that was needed to shrink the bearings enough and gave me a nice place to punch them out.

That's a good point slips.... You being an active metal worker and having to do that kind of thing EVERY week .. Working on trains and stuff... Actual proven practical experience!  .. I like that! 

Holy crap! ... Epiphany! ... Just realised... John already has a thumbs up like button... Looks like this 

Takes me awhile.. But I get there! 

[slipperymongoose]

Why thank you janx it's not often you compliment me haha

It ain't easy!

Maybe, maybe not...... its impossible to say 

However, considering you are a metal worker and therefore (should be) aware of the possibility of heat distortion and the problems it can cause perhaps you should have specified that your method carries inherent risks rather than me having to do it for you and to not assume people are `smart` enough to already know 

[Jimbob]

If in doubt ask

[slipperymongoose]

Oh cool so now I have my own personal speaker. Cool hey sledge I want to punch a baby how should I do it? From an engineers perspective?

[codajastal]

OMFG will you people just grow the f%$k up.
If something works for you then use it and if not then dont and if you are not sure then ask someone that is...... simples
