Bearings

[sefer]

Hey thanks for that.

Who knew finding a bearing was going to be so hard :slap:

The general opinion so far is that unless I go genunine I won't find a match, and while I'm still waiting for a price from kawasaki I'm thinking it's going to be a lot.

I'm thinking it's going to come down to three options (excluding genunine on assumtion that I'm not going to want to pay their cost.. ) :

1: I use Loctite bearing retainer and a $8 6205 bearing (easiest, but safe?)

2: I shave the set ring .3 each side and use a $20 6205 n bearing (should be easy enought to do myself with no special tools, but probably not ideal)

3: I find someone to machine either a $8 6205, or $20 6205 n bearing to the right specs (harder, cost of labour unknown, prob safest)

Option 4: Buy the factory part

Friend of mine who knows his stuff doesn't recommend the loctite only, bearing may still move. I trust this guy implicitly, so I retract my earlier suggestion.

Now I remember the guy from Saeco here in Chch, it's Phil. iirc they have two branches, and iirc he's at Blenhiem road way? Ask about, you'll find him, he knows his stuff (used to be at South Island Bearnings when they were still Mainland Bearings). Tell him Malcolm from Safe Rs suggested he'd be the man with the knowledge

Option 4 is only an option if they're reasonably priced in my book

Thanks for that info. I've given up on the direct approach for today (i.e. actually going into places), but have emailed a buch of places to see what they say. Probably a good idea all told, gives them a chance to check their details without having to worry about me waiting.

I've actually done quite a bit of reseach on this myself now, having found some NTN catalogues online, and have discovered that the standard 6205n bearing does have a wider groove at a min of 1.65mm. Still not quite wide enough, but I could get the ring down to fit that without too much effort (without calipers, the ring itself is around 1.6 - 1.8mm).

I've actually just finished looking into the loctite option, and it's not as bad as I though it might be. The tech sheets show that it should work no problem if you use the strongest retainer product they have, as it doesn't degrade in strength at all over 1000 hrs in use in a 125 degree oil environment (where as the med strength one degrades to about 80% at that time). Still I'd probably only use it in conjunction with option 2.

Yeah, you wouldn't be the first to loctite a bearing in. No chance of getting a thinner clip to fit? Try Paykels engineering supplies here in town.

ONly thing to watch if using loctite is that the clip may locate as well as secure. So you will need to be VERY careful that you get the bearing in exactly the right position . Sometimes this controls things like endfloat on shafts and such like (can't say if this is the case in your situation).

I probably could, but then there will probably be too much movement in it from the case groove.

I think that if I can't get anything else tomorrow I'll get them to order me in some of the NTN 6205n bearings and shave the ring. Shouldn't be too hard as I'll probably only need to take 1-2mm off.

Yeah I have considered that too. I probably won't go that way anyway now, but if it ends up that way I'll try to measure up the placement based on where the old bearing locates.

A picture is better than words, plus is probably of intrest to those zxr owners who wouldn't dare split their case (bright bastards )

First picture shows the transmission with the output shaft in place. The clutch shaft has an identical set-up as far as the bearings go.

Yay, Kawasaki finally got back to me today, and I was suprised, the bearings actually aren't that much at $27 each. The catch....ex Japan at least three weeks wait

Well I am not waiting that long, so I'm going to shoot off emails to every kawa dealer I can now seeing if they have them in stock. Then I'm going to see if I can order the NTN bearings with the slightly wider groove and what they cost. I'll just go with the first place to be able to get me either.

option 5
get the bearing with the 1.35 mm groove,get a 1.35 mm retaining ring at the same time.
And use retaining compound as well,paying attention to what Ixion said in post #20

[sefer]

Wow! and I thought Kawasaki parts were expensive. I just called Honda to find out what they charge for the same bearing (managed to find a part number for it).......$70! Granted it's an older bike ('83) and seems to be the only model to use this bearing, but f**k what a difference!


Apparently Saeco now have the bearings I want in stock, so I'll give it till Monday on the off chance that one of the Kawa dealers have some in stock. If not I'll get the ones from Saeco, assuming the price is about the same (never actually priced them there as it came down to I needed them).

Thanks for all the advice and efforts on my behalf guys. I'll let you know how I get on. Hopefully I'll have a roaring (...ok whining) baby by Tuesday
