CB500/550 / Re: Rocker Housing - Stuck??
« Last post by Mike_Berkshire on Today at 09:43:04 PM »
Mine was fairly solid, might be worth tapping it back down where it is sligjhtly raised. I found my big rubber mallet worked making sure I  tapped it all round including some upper blows on the intake side.
I also sprayed WD40 type stuff all around the dealing area.
Thanks Ted. I have just given it another good squirting and a firmer tapping with a plastic headed mallet to no avail. I havent tried tapping upwards from the intake side; i will try that tomorrow morning after an overnight soak. Where did you bash it upwards on the intake side?

I can slide a polished paint scraper around between the castings to the right hand dowel but not the left hand one so I guess its seized on the left one. Im assuming the dowels are supposed to be locked into the head as opposed to the rocker housing?

I've noticed quite a few Websites where phone numbers, actual postal address are missing as well as a lack of e-mail address.
Some that have them keep them well hidden it seems with lots of navigation needed.

If you are a limited company in the UK you must put (at least) your registered address on your website.

That address is often one of a row of brass plaques at an office full of letter boxes!

I'll put it out there, plug fouling can also be caused by oil burning.
Worn rings or valve stem seals/ guide wear.

Only if someone complains Andy.

There’s nothing stopping people selling stuff on here.

If members find it useful then good…

Im assuming that the dowels are designed to be retained in the head and not in the rocker housing? Giving the top end of the dowel a few taps with a blunt punch might hep free off some of the corrosion?

2 solid dowels there, you can see the top of them, soak with penetrating oil and leave it with overnight. If still stuck, gentle diffused heat will help. Don't forget to remove the all the tappets before trying to remove the rocker cover.
Thanks Julie. I will douse them in penetrating oil and leave overnight as suggested. Its probably a good idea to put the bolts back in to keep the castings flush? I will see how things are tomorrow morning.
