Doms CB550F1 project

Thought the original spec was 180mm with a max spec of 181mm, which that drum clearly shows to be the same max spec.

Plus it's supposed to be the equivalent of the 42610-SB2-010 which you listed.

As i have already stated on this thread, you have to be careful of aftermarket drums. It needs to be 180mm spot on or like the old Honda ones were 179.850mm. The AP lockheed will be a tad over 180mm.
Try a Brembo 14.5069.10  or a Bosch 0 986 477 063

These were the last one i bought for Mick's and Roo's hub >>>https://www.autodoc.co.uk/brembo/1657868

The specs listed show it as being 180mm. AP Lockheed are a decent make.

That Brembo one is mage expensive, especially when all you want is the liner.

[Trigger]

Not expensive at £60 per drum. You get what you pay for.

My mate who is a window fitter had worn out his OEM brake disc's after 75000 miles on his van and he replaced them with cheap shite from europarts. They only lasted 10000miles

Before I commit to getting this hub relined, what's going on here with the alignment?

[Oddjob]

Alignment Dom? Please clarify.

Correct me if I’m wrong here but weren’t AP Lockheed original equipment on some 750f models?

Will do when I can but for some reason I can't upload photos today?!

When using a 500 air filter in a 550 airbox how do I prevent it dropping it the bottom?

Hmm, I've had to resize my photos which I've not needed to do before.  Here you go Trigger.

Sorry Dom, hard to tell from those pictures. I thought you had the wheel stripped down and that is the picture i was after to ID the hub

I did have but put it back together so I can move it about in my cramped garage.  It's a standard 550f rear hub so I could send you photos from one on ebay?

I got it started today after a carb rebuild, it sounded a bit rough but I've only done the cam chain adjustment so not looked at the tappets or timing! I remembered I'd not checked the compression so did a test after it's brief time running.  The results were worryingly poor, 70,75, 80, 82ish, as its not been started since 2016/17 I'm guessing I've got either piston ring wear or very poorly adjusted tappets. Is this likely to be the case on 32k?

I have found that it's not running on points but electronic ignition (Dyna S) which was a nice surprise as its one less thing to have to mess around with.

When using a 500 air filter in a 550 airbox how do I prevent it dropping it the bottom?

AFAIK the filter will sit correctly. I seem to recall it's the same psychical shape and size, just with a hole in the bottom on the 550.

It will sit down too far meaning it doesn't line up with the airbox hole. I think the 550 filter is held up by the metal pipe and gauge screen.

Regarding the rear hub alignment I mentioned earlier, there is a photo a few posts back where the sprocket carrier isn't in alignment with the hub.
