K5 clutch info

[Snapey]

I've got the clutch apart again and looking for information on sizes. My K2 manual tells me there are three different drive plates which I have but bigger in diameter to the manual. The K5 supplement says they're all the same in thickness but all different part numbers. I've searched through here but found nothing.

I'm totally confused so if anyone knows the thickness, number of pads and internal diameters of K5 clutch plate could you please let me know.

[Snapey]

Not only am I confused so is Mr Suzuki. The part numbers of Nos. 1, 2 & 3 drive plates are the same for K2 and K5 but the manual and the supplement have them different sizes.

Stuffed if I know.

Later clutch

From looking at part numbers both early and later clutches use the same 3 cork covered plates the first and last plates are different to each other and the other plates and all the others plates are the same as each other but all the part numbers are common for each of the 3 different plates across all years .
Hope this helps

Sorry Seth that's no help but thanks anyway.     The inside diameter of nine of the plates according to the K2 manual should be 101mm ... my K5 are 112mm and that's what started this search for K5 information only to see they have the same part numbers. That being the case I'd expect K2 & K5 to be the same product.

Thickness of the plates is an issue and what do you believe? The K2 manual says service limit  is .095" and K5 .115. I also measured a spring which was 30mm ... manual says 73.9 ... now that's a good mistake.

I'm sure someone more knowledgeable than me will be able to sort this for you Snapey, however, my take on reading the above posts is, if the manual & Seths info says it should be 'this' & you have 'different' in there, maybe the wrong bits have been put in by a PO?     I take it it's the r&b we're talking about here.

[Snapey]

That's the one Col. The plates are still sticking & I thought I'd make sure it's assembled by the book. When I saw the difference between my plates and the sizes my K2 factory manual had I thought they must have changed things in the later models. I'll pull it apart again & check but I don't think there's a No. 2 plate. It might just be the oil so I'll try a semi synthetic 15w40 this time. It didn't like diesel or 10w30 but when it's free the clutch is brilliant.

Judging by the misprint on the spring size I'd say the manual is full of mistakes.

According to my genuine factory manwell the clutch springs on all models is 28.96mm (1.140) and have a limit of 27.6 (1.087) and the clutch drive plate thickness for number 1,2 and 3 is 3.22 -3.38mm (0.127-0133) and they are the same for all years as far as I can see.

@Snapey
I'd say the plates are common across all years I'd say that the specs you seen has a missprint and go with the below wear limits.

Snapey, im guessing you know all this already but just trying to help. 3 diff friction plates. inside with lager internal diameter. outside with smaller pads, fits into shallow slots. 19 plates all up. Spring length as above, min thickness friction plates as above. Checked on 3 diff manuals i have. Why it drags? No idea.

[Snapey]

Would Suzuki update a component but retain the original part number? That seems to be the case here. I haven't found a std/spec size for drive plates in my K2 manual, only the service limit of 2.42mm (0.095") which I'm well above at 0.131"

Page 3-37: Clutch spring free length service limit: 73.9mm (2.909") mine are 30mm. I hope Suzuki sacked the proof reader.

Another question regarding the manual: Did Suzuki print a new manual for each year of production or just a supplementary or update and did they stop at K5? My 2001 manual has quite a few revision pages glued in also.

[seth]

They do update part numbers but those parts replace the older part directly and then the older part is deleted so all older bikes will use the new parts .
But normally they say the old part number and say it's been replaced by the newer part number .
The later models only had updated pages for the differences .
I'm sure that @gsxbarmy has put them in the downloads section so you can get them here if you look .

Snapey, any update on clutch ?

[gsxbarmy]

@Snapey @seth

I've just done a clutch component comparison between all models

Cheers @gsxbarmy
It seams from the comparison
There are 2 part numbers for the clutch basket (with k4 on being the same) and the plates having 3 numbers on the later ones rather than the 1, 10A and 10 B on the earlier ones but sharing the same part number for the same parts.
The clutches are the same across all years apart from the baskets on very early models(k2-k3).
Unless I've missed something.

Nope - That's exactly how I read it @seth .....
