im looking for caterpillar NLGI2 greases replacaments especially from mobil, then from texaco and other companies cat greases spec below cat advanced 3% moly cat ultra 5% moly
For Mobil grease you need to be looking at the Mobilgrease XHP Premium Series. Off the top of my head I would use XHP462 Moly in NLGI #2 as a replacement for Cat Advanced Moly 3 and XHP681 Mine as a replacement for Ultra Moly 5 but it's only available in NLGI #1 but not NLGI #2. Is your system manual greasing or automatic..?
D-A Lubricants Inc. ALL D-A Products are exceptional: Grease: MagnaPlex is 3% Moly 5 is 5% DuraPlex is 3% www.dalube.com
However good the products are I doubt they're available in Poland......
Schaeffers has more than one grease that meets these specs.... And I ship to Poland. Please contact me,
Nige, No, the sell throughout Europe, North and South America, Asia and Australia. Look at there web site. Bob
My apologies. I'd never heard of them so assumed they were simply in N America. That'll teach me to do my homework better next time ...........
Mobilgrease 322 mine looks like cat 5% moly except thickener type. .. mobil got lithium. cat calcium. Whats the difference ?
In reality, nothing. Effectively there are 2 major types of thickening agent used in most brands of grease. Cat happens to use calcium sulfonate, Mobil uses lithium. The end result in as much as how the grease works in a machine will be exactly the same.
Ok one more thing. .. mobilgrease 462moly. .. got viscosity cst at 40. .. 460 and cat 3% moly got 320... which viscosity is better and why ?
Maybe we are getting off track here and focusing too much on specifications and details. What exactly is the application for both greases you originally mentioned and are they being used in automatic gease systems or is the grease applied manually using an external grease gun.
Backhoe loader and grease gun
In that case Mobil 322 would be fine for your application. Base Oil Stock Viscosity really only becomes a factor when the grease is applied via an automatic lubricator system. For high-performance greases for use in an automatic system the first thing you look at is the NLGI Number to see how pumpable it is, taking into account the ambient climate conditions where the machine in working. For example in a desert you might need an NLGI #2, in the middle of Siberia you might need an NLGI #00 or even 000 to make it pumpable. Then look at the results for the 4-ball weld test and the scar test. The higher the value in 4-ball indicates a grease more capable of supporting heavier loads than one with a lower value, for the scar test the shorter the scar length the more capable the grease is of maintaining a lubricant film before breaking down. Low-speed high-load applications generally need 5% moly and the size of the moly particles can also be a factor, the smaller the particle size (in general terms) the better.
When you change greases, pump a little extra and a little sooner than otherwise. Just for a few greasings to be sure you don't plug up a joint from incompatible greases. Not sure if this is a cause, but I have my suspicions...
Always a good plan if you change grease brands, even if the 2 brands are allegedly compatible.
