550 F2 started!

[Laverdaroo]

Honda top set starts 06110, bottom set 06111. 500 is then 323 550 is 374 last 3 numbers more or less dont matter

so 550 top set would be 06110374S01
bottom set would be 06111374T00               jst had a quick look up at DSS

thanks Bryan, youre a ledge mate. I havent forgotten about your parts book its permanently on the kitchen table being studied on a daily basis. Am I ok to hang onto it a bit longer ......soz to be cheeky!

[Bryanj]

Youre fine, i know where it is!

[Laverdaroo]

Thanks mate, you're a gent.

On a different matter........... I posted up in the desperately seeking page but I'll bob a copy up on here too,    more exposure etc

Hi all,

******Has anybody got one of these lurking anywhere that they want rid of? My tank didnt come with one on so hard to lift once the catch it disengaged. I've a new lock for it fitted but just need the spring...............Anybody?

Part number 177353-90000 fuel filler spring (CB550, 750 et al)

So, interesting. I’ve spent the last couple of nights stripping the wheels down to get them sorted but have got a bit stumped. All going well, wheels stripped, hubs in dishwasher to get the crap off etc.
But when trying to part number up the Cush drive I hit a snag. My rear hub, as shown, has 4 Cush inserts that the wheel studs push into, just like the 400. When I look in the parts book all I can find are the part numbers snd diagrams for the hub with the removable Cush blocks, like what you get on more modern bikes still.

Did the 550 have this hub arrangement or not snd if not what the bloody hell have I ended up with? The rims are Akront ally ones and are in fair nick but this hub has me a bit stumped. Any ideas for Cush drive part numbers anyone?

That's not a 550 hub Roo. no idea what it is. It looks like a Honda, the brake plate looks like a 550 one though. Probably replaced by PO when the brake liner broke up, as they do.

[Bryanj]

I agree nott a 500 or 550, could it be a 450, ask Ash

[deltarider]

I've seen them on the CB350F and CB400F.

[Laverdaroo]

I havent chucked a tape at it yet but I thought 400 wben I first noticed it, Ash, any idea?

I'll measure it this arvo when I get home and into the burrow.


Bit odd s its been laced to the 550 rim. Soes anybody have one of teh cush inserts that they can measure for me? When I took them out they were flush with the top of the rim as they shpould be but had a 7mm gap underneath and didnt go all the way down to the bottom of the recess like tehy do on the 400. Also when you turn the hub over there are holes in the back so you can tap out the bushes, (not that I didnt have to muler them into submission and drill them out).

So some similarities to the 400 but not quite and still need to get these cush's sorted! The spokes are passable so I'll probably reuse them which is a bit easier as at least somebody else has had the faff of sizing them but As mentioned, a bit stumped tbh!

Looks Honda but stamping isn't Honda. No 617 model, they stopped using middle number just before 500.

Either way it's not the right one.

[Laverdaroo]

NI I kno but holing to matcch something up with it hence the request for the dims of the rear cush inserts.

[Laverdaroo]

Can anybody just clarify something for me?
I've taken the bearings out of my 'mystery hub' and see that the two sizes are 6305LU and 6304LU (single rubber shield) As it seems that the majority of manufacturers /suppliers only carry the 2RS (twin rubber shield) variants and it' order only for the LU, would it be detrimental to fit a 2RS item?
I appreciate that the spindle is lubricated but does part of that lubrication spread to the back of the bearing when in use hence the open rear side of the bearing? Kind of answering my own question but thought to ask before purchasing through a bearing supplier rather than DSS?

[Bryanj]

Fine to use 2rs, if you insist on only one but the 2 and remove one side(not)

[Laverdaroo]

Nice one, thanks Bryan
