Question 1 : Why is 15W-50 heavy duty engine oil a good alternative for my farming diesel equipment?
Question 2: What is the best grease recommended for agricultural equipment and what type of grease will provide the longest service life between re-lubrication?
Question 3: What do you recommend to extend the life of the hydraulic and drive-line components in farm equipment?
Question 4: What would be the proper grease to use in manure pump impeller and driveline bearings that are submerged, would there be a benefit to using the Mystik Multi Purpose with the calcium soap thickener. Is the antimony the best anticorrosive for this type of operating environment?
Question 5: I own a Wood Mizer LT HD 40 portable sawmill. In their hydraulic system manual they recommend Amoco Rykon, Mobil Multipurpose ATF or Mobil SHC 526 in cold weather. The hydraulic fluid I use in my tractors is your Mystik JT-5 Trans-Hydraulic. Can I use this in the saw mill?
Question 6: Does Mystik make a Gear Lubricant that is comparable or better than the 600W gear lube? The 600W gear lube is what Henry Ford used in the Model A transmissions and differentials. It consisted of a 140W oil with some kind of sticky additive blended with it. It is also very dark in color. I am looking for a lube that is more amber in color, so I can tell if I have problems when I drain the lube.
Question 7: Is ISOVG46 hydraulic oil compatible with universal tractor hydraulic oil? My equipment currently has ISOVG46 in it. When changing oil, I can not remove 100% of the oil (maybe 90-95%). Is it alright to refill with universal tractor type with out damaging the hydraulic system? I am mainly concerned about my GEHL 6635 skid steer loaders.
Question 8 : Which Mystik grease is best for boat trailer wheel bearings, JT-6, JT-6 High Temp, or the SX-6 synthetic?Answers
Answer 1: 15W-50 offers better wear protection and oil consumption control, especially in severe duty applications. The added measure of film strength contributed by higher temperature viscosity provides additional protection compared to other 15W oils.
Answer 2: Farm equipment, like most construction equipment operating in heavily contaminated applications, can benefit from greases that contain high molysulfide (moly). Moly greases offer a wide temperature range protection and equipment wear protection from the abrasion caused by dust. Greases that have higher temperature ranges with good adhesion properties will stay in service longer while reducing wear.
Answer 3: Use a universal tractor hydraulic fluid. Make sure you get one of the highest quality type available from your lubricant supplier. For example, some products available are of such quality that they offer extended component life warranty when used over the life of the equipment. Some farm managers have found that utilizing used oil analysis can also provide answers to lubricant service life as well as detecting potential problems.
Answer 4: Because of its excellent water resistance, Mystik JT-6 Multi-Purpose Grease is an excellent grease for submerged applications. This is a result of the Anhydrous Calcium thickener and the polymer-fortified base oils. Mystik JT-6 Multi-Purpose Grease does contain rust inhibitors that provide corrosion protection, though not Antimony. Antimony is used as an Extreme Pressure additive.
Answer 5: The hydraulic system manual for your sawmill recommends a number of different types of fluid. The Amoco Rykon is an Antiwear Hydraulic Oil, the Mobil Multipurpose ATF is an Automatic Transmission Fluid, and the Mobil SHC 526 is a synthetic Antiwear Hydraulic Oil. Based on these recommendations, I would recommend the use of Mystik JT-5 which is similar in viscosity to the other products and will provide excellent antiwear properties for the hydraulic pump in your system.
Answer 7: You should not experience any compatibility issues mixing Anti-wear hydraulic 46 fluid with universal tractor hydraulic fluid in the conditions you have related. I would caution you that if the system contains wet brakes and PTO clutches, the anti-wear hydraulic fluid does not have the friction properties that are typically required for these applications. Consequently you would be better served to remain with the universal tractor hydraulic fluid.
Answer 8: Actually, both the Mystik JT-6 High Temp and Mystik SX-6 will work well for this application. My actual preference is for SX-6 because of the synthetic component that actually reduces operating temperatures of the bearings. JT-6 Multi-purpose grease is formulated for chassis, fifth wheels, etc. It is not a high speed wheel bearing grease.
