I'm trying to remove the oil filter rotor on my '72 Cb450. I bought the spanner, but using it just turns the motor. Clymer says to straighten the tab on the washer - does that mean "bash" it flat, thus allowing the bolt to turn? The Honda Manual doesn't mention the washer. How did they install that washer and bend the tab up?

Any thoughts on how to remove the nut holding the rotor on?

Stafford... Yes, using a pin punch or small screwdriver, move the tab out of the slot and tap it flat.... One or two pennies jammed between the primary gears will "lock" the crankshaft allowing the "nut" to be removed.... the "cup" part of the filter will then pull off. You should have already removed the "rotor" or "spinner" from the center of the "cup". (remove circlip/thread 6mm bolt in, etc.....)

the lock washer (part #11) will have a (or 2) tab bent down into the nut slots just use a small punch to bend them up, put the motor in low gear and stand on the brake to keep engine from turning when you loosen the nut, that is if you don't have the side case off, otherwise the penny trick will work ok

Jayel.... I just assumed anyone/everyone would remove the cover and check/clean the oil pick-up screen while they were at it..... I do it as SOP.....

Should I remove the side cover? I thought that cleaning the rotor and cup is all that is necessary. Doesn't removing the side cover mean a new gasket every time the cover is removed? If so, is gasket thickness critical, or can I make my own?

two schools of thought on side case removal, if you pull it off and don't have one you're SOL until you get one, if you have one and don't need it you will sooner or later, so get the gasket they're cheap enough and it is better to check that lower oil screen,don't think thickness is critical but again the real gasket is cheap and availible, your call :)

I make it a point to keep a complete gasket kit on hand for each bike - you just never know with these old bikes......
I wait till one drops through the cracks on EBay, pick them up cheap.

It seems as though my last post didn't make it.

I have a gasket for the right side cover, no problem. It appears that I have to remove both the footrest and the exhaust (another gasket) in order to remove the side cover. Is this right? Seem like a lot to do just to clean the oil filter. I have been labouring under the impression that removing the rotor and cap would allow access to anything that needs to be cleaned. I guess not.

Any thoughts will be welcome. Is there an easier way to do this, or is this really what needs to be done to clean the oil filter?
