Headlamp Bowl
« on: January 02, 2020, 07:31:18 PM »
I would like to replace the headlamp bowl as it has a few cracks, I have found several on ebay but they are different to mine as they all have a large indent to one side (photo) mine is quite shallow and it is very difficult to get all the wiring in, perhaps mine is not the correct one?  why the large indent?

You need a CB550/ F 1 or F2 bowl. You are looking at 550k, 500 four or 750/4 K. Your wiring goes in a separate box which is under the tank. If you can hang on until tomorrow, I may have the one you need. Just thinking out loud now, what model wiring loom has your bike got on it 🤔

I don't have a box under the tank - all the wires join in the headlamp and the ignition switch is between the clocks, the loom reaches the headlamp bowl with ease it's just hard to squeeze the rats nest inside when fitting the headlamp.

OK. So it sounds like you have a CB550/4 F2 headlamp bowl, which is shallow, as the wiring all goes back to a bundle under the tank on the F2. So, assuming yours is an F1 as you don't have the electrics box under the tank, all the wiring goes in the headlamp bowl, and the bowl should be deeper... That's why you are having trouble cramming it all in there.

Yes that makes sense but it's hard to see the depth of the bowl in a photo online, which one do I need - I assume the one with the side indent would be no good.

All the ones on Ebay have the side indent and they do look deeper than mine so I think I would be okay with that, mine is almost impossible to get the wiring in, any idea why there is an indent in just one side?

The switch gear wiring on a 550 F1/F2 runs to a box under the tank and that is the main connection place and the bowl on a F is very shallow as it doesn't have many connectors in it.

Here is a pic of a F bowl and you will see that it is not as deep as the ones from the rest of the 550's.

Ah yes that's the one I have and explains why the wiring is so hard to fit in. My bike does seem to be a bit of a mix up of parts.

A CB550 F1/F2 will have the code HM32M on the back of it. It is the same set up as a 400 Four but a larger dia bowl  ;)
