Installing sleeves in 730

[J. R. McVay, Sr.]

I'm going to install sleeves in a 730 block. I read in 2 different manuals--one said use vaseline and the other said petroleum jelly. What do you all say?

 

[Mike in Mn.]

I think there the same thing, I use ultra-copper silicone sealer and have real good luck with that.

 

[John Saeli]

Vaseoline is petroleum jelly.

Just looking to learn something today!! I thought that petroleum and rubber o-rings were not to be used together. I have read/heard that vegatable oil is what to use. ie, fluffo crisco. Anything to all of this or is this just personal choices---just wondering---have not BTDT--gobble

Those o-rings will come in contact with oil from the crankcase.

John deere sells some o-ring soap that works very well it is a little expensive but will last a long time. Dump the soap in a container big enough for the o-rings to fit in. After they have all sat in it for a while place them on the sleeve then return remaining soap back to the container.

I have also used almost every kind of liquid dish soap you can thank of. best of luck.

There is a special soap that is made just for that purpose. You have to buy it in quarts which is a lifetime supply for most of us. I have my lifetimes supply that I would gladly share with you if you were close by. Most good dealerships should have it or be able to get it.

My wifes grandfather used to use some nasty old black tar looking paint on the o ring, sleeve and block surface. I can't believe it worked but one WD45 was overhauled in 67 and the other in 70 and neither is leaking yet. Personally wouldn't try it.

Whatever you do, DON'T use permatex. Tried it years ago on a 1030, it caused the O-ring to swell up and actually compress the sleeves enough and score the pistons.

I run emery cloth around the sleeve hole and smooth up where the o-ring sits. Usually just use motor oil but have used vaseline/petroleum on the newer 504 motors. No problems yet.

As John S said Vasoline is petrolium jelly. We used GoJo hand cleaner, (wright or wrong), because Vasoline wasn't a common thing in the shop. We always tried to push the sleeves in by hand, but if they didn't go, we used the hammer handle to tunk them down. If the sleeve didn't seam to be seated tight, and wanted to push back up, it was odvious that the O ring had rolled, rather than sliding into the bore. You should be able to tell when the sleeve is setting happy in the block.

Cummins recommends,believe it or not KY Jelly,water soluble you know.and won't damage the rubber O rings.LOL

If the orings are silicone material[usually a color other than black] do not use a petroleum base lube. It swells the silicone ones and they will fail, trust me ,I learned the hard way. As mentioned earlier the soap lube is the way to go if you are not sure what kind of orings your kit is using. Years ago the CASE supplied kits switched to silicone base orings for the 504's in some models. Their service manual said to use petroleum jelly for lube on installation, WRONG, these orings failed on those jobs. I asked for warranty and basiclly I was told tough crap. I ate those jobs. Don"t make the same mistake I did. Rod.

Sometimes the oring kit tells u what to use .But if it does not i use dish soap just to be safe

In 1965 at the Case Factory School they wanted us to use Brake fluid.
