Mixing Oil and Water: A Recipe for Downtime

While the oil may be below saturation during operation, as the temperature cools down, water comes out of solution and becomes free or emulsified. As an example, a circulating lube oil at 140⁰F may have 500 ppm of water (0.05%) present in the dissolved phase, but cooling that oil down to 80⁰F may result in as much as 400 ppm coming out of.

Normal Operating Temperature for an Automatic Transmission

 · However, if your transmission is slipping a lot or you are pulling something heavy, the coolant may not be enough to cool the transmission efficiency and the temperature may rise drastically to temperatures over 240 degrees.. The older automatic transmission may not use coolant lines to the transmission, and these are even more sensitive to high loads.

Gear Lubricant Characteristics and Viscosity

An oil viscosity that is too high will result in excess friction and degradation of oil properties associated with high oil operating temperature. In cold climates gear lubricants should flow easily at low temperature. Gear oils should have a minimum pour point of 5° C (9° F) lower than the lowest expected temperature. The pour point for.

Lubrication Checkup: Gearbox Overheating

 · An oil-temperature rise reacts according to the Arrhenius rule—a temperature- change-dependent failure-rate rule—that states for every 18 degrees F (10 degrees C) increase in temperature of the oil, the lubricant life cycle is halved. Your higher gearbox temperature means the unit is in danger of a premature failure.

Troubleshooter: Engine Temps

 · Diesel engines generate high internal temperatures and this heat wreaks havoc with the various systems. In addition to keeping the engine from overheating, the cooling system on a modern diesel must also maintain the temperature of the lubrication oil, transmission oil, air intake, and fuel.

Causes of Overheating in Outboard Motors

 · A water flow problem is indicated if the water temperature is excessively high. Lack of fresh water can be noted if there is a large increase in temperature between the inlet and and outlet of the heat exchanger. Water pump failure can also be caused by ….

Cummins ISX High Oil Temp!

 · Oil temp is running way too hot. 250 plus when loaded. Truck is not being used until this is resolved. The rad was replaced a month ago and coolant temp rarley goes above 195. Stays about 180 most of the time. The oil temp sensor, oil cooler and oil thermostat have all been replaced since the problem started. I'm completely baffled. Please help.

 · 7 Causes of High Oil Pressure. Cold Engine. Wrong Oil grade. Blocked passage. Faulty oil pressure sensor. Faulty relief valve. Contaminated or damaged Oil Filter. Poor quality oil. Here is a more detailed list of the most common causes of high oil pressure.

Marine Transmissions

 · Transmission oil pressure remains roughly the same when the engine is in gear, whether at idle or full rpm. Oil temperature varies with propeller load and seawater temperature, but should also be monitored for uncharacteristic change. "The majority of transmissions run cooler than they are designed to run," Brunn says.

Transmission Temperature Chart

Keeping the transmission temperature between 175 and 200 degrees will allow the fluid to last the longest. This is the normal operating temperature for a transmission. Remember the fluid is the life line or blood of the transmission.

Possible Causes of Gearbox Overheating

The problem is worse when using a mineral oil with an ISO viscosity grade of 320." Gearbox overheating can be linked to many different root causes. To perform a proper investigation into why this gearbox may be experiencing overheating, an in-depth list of data must be collected, including the following: Operating temperatures; Ambient temperatures.

Important Temperatures to Monitor When Towing and How to

The key temperatures to monitor when towing are the transmission fluid, engine oil and coolant temperatures. Each of these fluids will have different ranges that you will want to stay within. For transmission fluid, the ideal operating temperature is between 160 and 200 degrees.

The reason why the gearbox oil temperature is too high

 · Insufficient Gear Injection Or Misalignment Of The Oil Hole Will Result In a High Gear Temperature, Which In Turn Will Be Transmitted To The Bearing Closer To The Gear To Make The Bearing Temperature High. 4.Oil Temperature Is Too High. In The Case Of Insufficient Cooling, The Oil Temperature Is Too High, So That The High-Speed Bearing.

Understand How Temperatures Affect Gearboxes

 · Either scenario puts gear drives at risk. (NOTE: To help overcome environmental extremes, oil heaters are often employed to maintain a minimum oil temperature of 40 F to 50 F during colder months, and air-to-oil or water/glycol-to-oil coolers are used to control oil operating temperatures during extreme heat.)
