Hi Brian,

This is the bolt I have and I THINK is the one shown in the parts list, it has a very small shoulder which is why is am unsure as the thread sits inside the bush.

Looks like you've got the rear shocks on the wrong sides. The bolt head goes on the outside, swap left to right etc and they should line up better thread wise.

I always prefer to fit a flat washer under the head of that bolt to stop it digging into the damper body. If doing so use a 10 x 35mm bolt

I also can't see any D washers in the top yoke?

Correct Bryan, saw it was a 500 frame and thought it must be a 500, keep forgetting about the 550K as we never got them. Wondered why the flanged nuts looked 7mm.

Yup Honda was very confusing, CB500K1 for UK, CB500K2 for USA and CB550K0 all being produced at same time

Response from seal supplier is that they are 35x48x11 which is the OEM size, so guess they'll be fine?

Hello once again,

Moving onto electrics.

I'm going to get an m-unit. And will likely get an li-ion or anti-gravity battery (depends on how small they come).

One item I'm unsure of is the voltage regulator/rectifier. Seems like Rick's unit is the recommended by reading past posts here, but there are dozens out there ranging from £20 to £120 and wondering if there's anything recent that may have changed this opinion?

My honest opinion is the charging system on these old Hondas is t crude for the super small li-on batteries and gell batteries, maybe a glass matt type which can use the ordinary rectifier and regulator. All the electronic ones are toast if connected backwards for even a second and same if for some reason the connection to battery is lost and volts climb

As always appreciate the advise Bryan!

I'm kinda committed to the small battery route as that's what I intended when making the electronics route.

I'll do a bit more research though.

Hi all,
Trying to get the rear wheel together but I'm unsure which way the D-ring is supposed to go?

I'm assuming with the flat side in the groove? But I'm struggling to get the hub all the way down. Or is it the other way around?

Thanks!

Flat side upwards IIRC. If it was flat side down the round side would face up, might as well use a fully round ring in that case.

Make sure you grease the ring where the bearing is located as well as the metal surface that rubs against it on the sprocket carrier, there should be 4 sunken grooves in the carrier, make sure they are full of grease. As the sprocket gets pulled forward by the chain it exerts so much pressure the rubbers inside the hub compress, the carrier moves on that surface slightly forward and gets returned by the pressure from the rubbers, if no grease everything wears and eventually the hub starts to oscillate and that means a new hub.

Brilliant, thanks Oddjob.

I was worried that with thle flat side up it would catch and possibly tear, when inserting the hub. I'll flip it and go again and will grease as recommended  8)

Just for once i am going to disagree with Ken and say flat side down as the groove is flat and you want the round bit to seal against the carrier, plus when i had a few nos ones thats the way they sat out of the packet,
Yes to lots of lube/grease on assembly and carfull with the screw in ring although i do believe mr silver sells pattern ones now.

You may well be right Bryan, I was working it out logically, although to be honest most grooves for o-rings are flat
