The manufacturer spec states the grease operating temp is only down to -20degC. The ambient temp was around -15degC. The manufacturer has suggested a lower temp grease as the would not recommend using at the lower end of the spec as the norm.
The temperature may have previously been lower...
The manufacturer was Millers Oils Delta EP2 Lithium based grease.
The ambient environment temperature was in the order of -15 deg C.
The seals were not reported to be hard but there was a leak detected.
I have experienced the use of a -20deg lithium based grease at low temperatures (about -15deg). The grease is used to lubricate some seawater seals and these were found to be passing. On inspection there was evidence of solidification and crytals present. Does anyone know if the grease expands...
Hi Guys
Thanks for the help, the grease is only used when fitting the seals, although it fills the cavities of the seals. There is no constant grease charging system.
I was interested to know if the grease expands, would this contribute to the seals leaking.
We replaced the grease with lower...
