I looked at the parts diagram and it shows the 2 washers. I only have the front washer on mine and it keeps working loose. 1981 CX500C 1983 GL650I Restored    Report

Yes, check for the washer on the cam shaft or in the impeller.  The first time I pulled mine, it stayed on the cam shaft, and I almost added the new one on top of it.  The second time, it stayed with the impeller, and I couldn't figure out why it would not come off the cam shaft. Also, the copper, outer, washer should be replaced (or heated with a propane torch) every time it's removed.  It IS the seal between the impeller and cam shaft.

Maybe that's why I'm getting water in the oil. I replaced mechanical seal, oil seal, head gaskets and it's still getting in. I have it disassembled right now should I get new washers or use the old 10mm? I also have pitting on the whole camshaft end. 1981 CX500C 1983 GL650I Restored    Report

Only ever have the ONE on there. The washer on the impeller nut side is a copper,"Crush" washer.If in good condition it can be re-annealed by heating to cherry red and natural cooling.

Some pitting is normal.  The area that the oil seal rides on needs to be smooth, and usually will be. Water in oil - make sure you replace the two water passage o-rings (on the case - to - rear cover seam).  A good source of water in oil and not the oil seal's fault.
