When installing new sleeves, what do you guys use to lubricate the "O" rings? I'm rebuilding an allis chalmer RC engine.

Vasaline, it won't swell the O rings like engine oil does.

straight Dawn liquid dish soap. "They" claim any petroleum base lube will turn to carbon over time with heat and become abrasive to o-rings as there is always minute working of sleeves in blocks using sleeves. Is it true? I don't know.

Use what the sleeve/o-ring manufacture tells you to use.

Glycerin works great. We also use it to lubricate the syringes in our vet kit.  
In expensive and available at any pharmacy.

Dawn dish soap is always good, and it won't swell the O-rings or degrade them, it just disolves. But best bet is to go to product website and see what they recomend. Petroleum products are not the best because of the previous reasons mentioned for sure. Good luck and let us all know what you decide to use and what was recomended.

I was taught many years ago to use liquid dish soap. Have ever since, and never had any issue. Was also taught to put very thin bead of high quality silicone in the corner of counterbore to help ensure sealing at top of sleeve. Olivers would leak there and leak coolant at sides of head gasket.

my IT manual says hydraulic brake fluid, or thick soap solution. Since brake fluid today may or may not be the same stuff as when that was written, I think I will use "thick soap solution" aka dish soap

I was told by an old AC mechanic that his son rebuilt a 200 and used oil and it swelled the sleeves enough to seize the engine.

We always used castor oil at dads shop. I always assumed that he had picked that up at an allis training school. That castor oil makes those O-rings super slick, the sleeves usually pop right into place when using it. Another thing we always did was before lubing the o-rings, use a small pocket screwdriver or pick and work it around the inside circumference of the o-ring. Purpose being to take any twist out of the o-ring. If you examine the outside of the o-ring you can see the seem, look closely!

Pankey, do you just apply the 111 to the o-rings after putting them on the sleeve or should you smear some on the block also? Second question does it firm up like regular silicone or stay in a gell state like dielectric grease? Third and final question can i obtain it from the local parts store, interested in giving it a try if its not too much trouble to find. Thanks alot!!

I was taught by an Allis mechanic to use very heavy water pump grease to lubricate the o rings and take a small round screw driver and put it under the o ring and go around the cylinder a few times to get out any twists in the o ring. He never had one go bad in the past 40 years I seen it used. I always used it on my WD and D17 also.
