Technical: Overheating

The most frequent cause of gearbox overheating is oil level and can be either too much or too little. Make sure the level is as specified by Cotta. Too little oil may result in reduced delivery or no delivery to moving parts and cause high friction and heat. Conversely, too much oil increases agitation by gears, bearings, and other moving parts which generates unwanted heat. Avoid the inclination to add more oil than necessary “just in case”. Oil levels are determined experimentally at the Cotta factory. If there are special operating circumstances such as pitch or roll, or, jerky motion that can cause the oil level to change, contact Cotta Engineering to discuss the best way to re-locate the oil level.
