Oil filter


Oil filter

Overpressure deforming the oil filter, immediately after starting the ice-cold engine, happened twice during the 2013 Polar Ice Ride. Once in Barrow and once on the frozen Beaufort Sea. A too thick oil couldn’t have caused it, because that poured out like it was water. Maybe the thin oil made it possible for the oil pump to build up a pressure that the ice-cold filter couldn’t handle. Every oil filter holds a valve or O-ring inside, which should open a bypass in case of overpressure. In extreme cold this can fail, with the result of blowing up the oil filter. After I winded a 220V – 100W resistance wire around it and pre-heated the filter it still occurred. Because this didn’t solve the problem, I’m going to try to have a special filter developed for the North Pole Ride. For sure I’ll take an original filter with me as a spare and make a hole on the inside beforehand. This way the oil can circulate without having to pass through the filter material itself and overpressure will be avoided.
If there is a company out there willing to do this for me, please inform me!
