Question about finding heavy oil

Larry B 1486 · May 7, 2009

This has nothing to do with IH tractors but I am always am on this board and everytime I have a question I always get a answer and do really appriciate it very much. What I have today is I bought a used disc mower from a HONEST dealer where a little old lady only used it on sunday afternoon. I had to rebuild the whole bar and put bearings in it and it was welded on. Have it all together and it leaks a little oil, not much just a little wet and can not find the leak. I have 90w gear oil in it. Is there a oil between 90/140 and gun grease? I am going to try to find the heaviest oil before you are into grease. Anyone might know what kind of oil I might try to find?

John Deere Multi-Lube is certainly heavier and readily available. If you are not famaliar with it, it is used in their single point pump baler lubricators and has a thin jelly consistency. I don't know whether it would be suitable in that application. Someone here may know, or there might be a JD technical assistance number that could help you.

We used to use some gear grease that was 120 a number of years ago. Used it in some heavy duty industrial bear boxes and as I recall it was made by Mobil. We have an Exxon/Mobil distributor locally that we bought most of our lubricants from... you may need to contact a wholesale distributor like that to find something if the "Tractor Supply type" stores do not have it. If it leaks now, it will still leak later with the heavier lube, especially when it gets hot.

The only thing I know of that is thicker than 85w-140 would be the John Deere corn head grease -- I know people use it in the gear boxes for steering on H's and M's, but I don't know if it would work in a gear box.

Best bet is to fix the leak...

Might try this stuff. Mobil 600W cylinder oil, used in steam engines. It can be purchased in small retail quantities from most anyplace that deals in Ford Model A parts, since the Model A transmission uses this oil. Like was said below, though, if it leaks 90W, it will leak 600W, it will just leak slower.

Mobil 600W Cylinder Oil

Just quickly...the Mobil 600W steam cylinder oil is a worm gear lube for when bronze is present. The EP additives in a "rear axle" oil ala 90W or 85W140 or the like are for steel on steel and will slowly break down bronze.

Mobil has started spec'ing SHC634 as a replacment for the 600W in some applications.

Next I'd look at a #0 or #00 grease. We used #00 grease in 5-axis robots I worked with, the motor had a spline machined into the servo motor output shafts and these mated with an internal planetary setup. This style of grease could still be "placed" like drywall mud but was much softer than the standard #2 grease we get out of tubes.

Another thought is to get a couple bottles of STP oil treatment...that stuff is viscous! I'm not sure how it rates as a standalone lubricant...but thick it is...

the one shot lube systems used 140 gear oil.
