The service manual says to use white lead on O-rings. Never heard of white lead. What is the best thing to use? Push straight down or twist? Hold them down with a bolt and washers so they don't pop out till the head is on? Use any kind of sealer on them? Thanks
 
Most use liquid dish soap. Something water based that is slippery is what most will say.

Remember that the sleeve must be able to drop all the way down and be able to turn by hand without the o rings before trying to install with o rings.
 
Dick is right. Don't use anything petroleum-based. I'll add: be sure the seal grooves and lower bores are perfectly clean, no burrs, and the seals don't get twisted when the sleeves go in.
 
Yes clean and then clean again the bottom and top areas where the sleeves will go. The with out the o-rings on them test fit them to see if they fit right. I used Dawn dish soap on all the ones I installed. No bolt or any thing to hold them in they should fit tight enough to hold them self's in
 
I just got a set of cylinder kits for a Buda this week. Instructions say to wash them thoroughly with hot water an detergent. They look perfectly clean but I'll do it anyway. The bores are honed and that can leave some abrasive behind. Can't be too clean when there's that much cost involved.
 
Oh, and about the white lead. I haven't seen that stuff for years. It's an off-white colored heavy paste. Used to be used in paints and in machine shops as a tapping and reaming lube. Best stuff ever for thread cutting in stringy, hard to machine steels. Toxic, of course. In this case it would lubricate and help to seal the sleeves. Seal ring should seal without any help.
 
The seals go on the sleeves on the B, C, CA, RC and more. The o rings go in the block on the D-10 thru the D-15.
