CB500/550 / Re: Headlight reflector
« Last post by McCabe-Thiele (Ted) on Today at 06:36:06 PM »
My 500 headlamp is  a standard UK style 7" unit.
It has the three lugs similar to those on the old sealed beam headlights.

I fitted a Land Rover Defender 90 type LED headlamp unit but pretty much any old style 7" headlamp will fit.

How to remove the output bearing.

Remove the gear next to to bearing, fit the shaft loosely in a vice so not to mark it and allow it to move and knock the bearing off the shaft so that it moves away from the collar, once it moves a little it will come off easily. Protect the end of the shaft when hitting it. Once off there is a really thin oring fitted between the bearing and the collar, on no account try to remove the collar unless it’s ruined. Do not under any circumstances insert anything between the bearing and the collar.

I've added the picture, it didn't work at first.

I don't think the bearing first over the collar? The collar seems to be bigger than the bearing.

Its the collar that I cant seem to remove. I've not tried heating it up yet, I'm going to try later.

Iirc there is an O ring between that collar and the gears so heat would ruin that.

CB500/550 / Headlight reflector

Is a CB550 and 750 reflector the same? Mine on my 550 is a Stanley 001-1217 but a previous owner has fitted a strange bulb that has meant they've used an oil seal to hold it in place.  Can I retro fit an H4 Led to it?

I would be tempted to get some local heat onto the spacer (not the shaft itself) followed by some gentle taps with a suitable thin and flat wooden wedge GENTLY inserted between the spacer and the bearing going slowly all the way round, these things usually let go with heat and gentle persuasion. If the wooden wedge doesn’t work get that old flat blade screwdriver out that you use to stir paint with! Good Luck.

I've just noticed the oil seal is not on the end of the camshaft, did it fall off when you took the rocker cover off?
Yes, that’s to one side for now

I would expect to see a bit more oil in the oil bath below the cams if the engine has been running for 3-4 minutes. Did the top end sound rattly when first started and did it quieten down after the oil began to circulate or did it sound the same? I am not really experienced with these engines but if one side of the head has more oil than the other I would be concerned the oil jet on one side is restricted and not delivering the correct amount of oil to that side.

The cam chain is picking up oil from the bottom of the engine as it goes around the crankshaft sprocket and it could be splashing oil at the top end as it comes back up to the camshaft. The oil filter is also in the bottom end where oil pressure is likely to be unrestricted.

It will be very messy but I’d be tempted to run the engine on the starter motor in short bursts with the rocker cover (and fuel tank) taken off and see if the oil is reaching the top end.

Well I convinced myself that I wasn’t getting any oil to the top end. I tried with the white paper for a couple of minutes but didn’t get any splashes. I’ve whipped the rocker cover off and I did have some oil up there.

As you can see the right hand oil bath has oil covering the bottom all over, the right hand bath has some oil but not as much. There are signs of oil on the tensioner bolt head and the valves but to be honest, I was expecting more, there is oil in the centrifugal filter as well and the rockers have a layer of oil on them.

The bike has probably run for around 3-4 minutes or so I guess, would this be about normal for a short start up after a rebuild?

Is the fact that there is some oil up there a good enough sign to put it back together and run it until winter?

I’m getting myself in a bit of a tizz as I know how weak these engines are regarding the oil delivery and camshaft and journals.

Any opinions would be welcome.
