I have a Nortrack 254 ( jinma 25 hp) and the oil pressure gauge needle is reading very high pressure. I do not think that there is an engine problem, with the readings so high I figure that some seal somewhere would be blown. I am thinking that I have a bad guage. Does anyone know how I could check to see if it is a gauge and if so where to buy a new one.
Check on your oil filter bracket there may be an adjusting nut. Mine was way too high after warmup. I adjusted it down into a more reasonable range. Although checking with a manual guage to check would also be a good to check your tractor guage
