Grease on the O-rings on the sleeves, Case 1370

What kind of grease shall I use on the 3 big O-rings on the sleeves?
The manual says vaseline or water soluble grease.
Why should it be water soluble?
Can I not use some ordinary grease or oil?
Some says soap or brake fluid.
 
This is one of those questions where you will get as many different answers as you have mechanics, personally I prefer a good dish soap, certainly slippery but will not attack the orings.

I would not use brake fluid at all, Have also used Vaseline and the gel hand soaps without the grit or pumice.

The important thing is cleanliness and if you do that right as far as preparing the bores, with a good lube you should be able to push the sleeves in without driving them.

Also, after the orings are on the sleeve I pick them up one place and put a smooth tool such a s a oring pick under all three and rotate it around the sleeve to allow the orings to untwist as can happen when you roll them into the grooves.

How should I clean the bore?
The sleeves were really hard to get out. By pressing from beneath I lift the tractor up in the front while pressing it out.
Shall I just clean it? Or can I use a sandpaper?
The manual says it would be possible to but the sleeve in again without the O-rings by hand and turn it by hand. Is it so?
 
Preparation is as important as installation. Sleeve bores must be totally clean, both upper & lower. No hints of carbon. I lightly hone the lower sleeve bores with sandpaper wrapped around my honing stones. Bores must be inspected for pitting and electrolysis tracking. When the block is ready for the sleeves, the sleeves, without the o rings installed, should fall into place. It is at this point that Sleeve Protrusion is measured.
When installing O Rings, The CASE Service Manual says to use Vaseoline, so why question it. It says to use it lightly, & only on the surface of the O Rings, don't get any behind it. Also, lightly lube the bore.
I've never used dowels on the heads either, as Mel says, the manifolds will do the aligning for you. I always lightly bolt all 3 manifolds on, drop in all the Head Bolts, lightly snug, then remove the manifolds.
Good luck.
 
I like to use a lubricating soap like Mel mentioned. Deere and Co. sells a soap product formulated for sleeve oring installation. Many of todays orings are made of materials different than when CASE printed the manuals years ago. Petroleum products can cause damage to many of the newer orings. Lubricating soap can be safely used on them all. Rod.
 
Grease can and will corrode ,petroleum jelly will not turn rancid like grease , one could also use mineral oil which also is s very good penetrating oil.
 
Rod: Several years ago I overhauled a 855 cu in Cummins & the instructions said to "use a petroleum grease to swell the O Rings". Said it in black & white. The bottom O Ring of any engine always receives oil splash.
 
I also recommend Deere oring soap oil will make the Orings swell up and become mushy. In a pinch I think straight antifreeze would be slippery enough to install the sleeves with.
 
Hi John, yes if the manufacturer specifies petroleum products, then that is proper for the application. Lubricating soap is the safe bet for those unknown products. I have samples of orings that the manufacturer refused warranty because a petroleum based lube was used for installation. Instruction with the kit did not state to avoid its use. Yes, I have had the eat a couple jobs because of that situation. I no longer guess, if I do not know, I use the soap. Rod.
 
We over hauled a 2590 about three years ago and had to tear apart again because o rings went bad. we had used assembly lube on them
