engine oil pressure///jd440ic

Post by dtoots1 » Mon Sep 25, 2017 12:04 pm

Finally got a new oil pressure gauge with numbers....the old electric operated original? kept showing up on the redline///shutoff line.....scary...

new gauges shows that i have something over 20psi oil pressure....gauge reads 20 40 60 and have to kinda guess at approximately 23 to 25psi. i think that i am running 10w30....book calls for 20w and says is ok to use 10w30. does not call for 30weight.

i do have a donor engine with oil pump in it could maybe rebuild and replace mine....but i don't know if this one has to be timed to work properly or if pressure i have will still be ok at 20 something,

need your inputs please

thanks

Pressure is fine, any good multi weight gas rated oil is fine as well.

that is great news..... thanks...

now question.....there is an oil port just a bit behind the hydraulic pump on the right side of engine...it has a nipple and a plug in it.....is this a test port for the hydraulic pressure.?if so i don't want to put a low pressure gauge on that......on a 2010 that is location for the oil pressure gauge. i don't find an access port on the hydraulic valve body...it is a six way blade.
i used the port for the sending unit when i put the oil pressure gauge in...that is located at the oil filter base....
thanks

It can be, it is normally where the pressure switch for electric hour meter goes.
