Butterfly Shaft Seals

[BadBird403]

Anyone know a good source for butterfly shaft seals for a 99 kat 600? Haven't been able to find any so far.

I don't know that they are sold separately

[Kreylyn]

They are just felt washers. Or are you looking for the nomex spacers?

I'm trying to find the rubber seals that fit around the shaft.

It's been a while since I pulled a set of 98+ down that far, so remind me... you have a pic of one of the seals? Are they something other than just viton o-rings or felt washers? Both can be sourced with out buying oem parts for much cheaper.

Mcmaster-carr or grainger for orings often is cheaper buying qty of 25 vs 1 OEM part.
A felt source and a hold punch - felt seals.

Help us help you, post some pics... :P

I tried to upload a pic, but its telling me I "don't have authorization to create or remove attachments" lol. This link shows a picture of one on a Mikuni. They call it a throttle shaft seal.

Um... Okay, honestly I'm confused, so bear with me here...

I'm not aware of that seal being used on the 99 Katana. I just don't remember ever running across it before, and it's not listed as far as I can find.

I've found the seal used on the older metal capped carbs used on the 1100 or 88 600. Part number 13651-51010 if you wanna source it from any OEM parts dealer.

The 89-97 BST33ss and BST36SS used on the 600s/750s used just felt washers as seals.

The 98+ BSR (you did list a 99 model yes? ) does not list that seal either.

It is listed on the 99 gsxR model. Is that what your asking about?

Anyways, to post a pic...

Yep, 99. Definitely a kat 600, with plastic tops. Link for the carb pics below. I've rebuilt older Mikuni and Hitachi carbs, so far I've never seen a carb not have these. This is my first time on a katana though.

I'd acquire one of the Part number 13651-51010 listed for the other bikes I mentioned above. It's very common for Suzuki to have parts like that, they don't manufacture, cross over to multiple bikes. It's likely the same part, but if you order 1 you can verify that prior to spending a lot of investment on them.

That's a first for me in working on those carbs for 14+ years

[BadBird403]

Thanks Kreylyn. I ordered one to test fit. Hope it works!

[Dylan Katanabruin]

who wouldve known lol? cant wait to hear if it fits

[BadBird403]

Update: I got the seal in from partzilla and it's a direct fit. Looks like I'll be ordering more to finish out the other carbs. Now if I can just get the stripped butterfly screws out........... lol
