I have a 1982 KZ1000 K LTD with the J motor. I would like to remove (delete) the oil cooler.
So looking at the service manual it looks like the oil outlets at the pressure sensor and end of the gallery on the side should be common.
So just as an experiment I tried putting a rubber plug on both of the cooler connections on the engine. Thinking that the oil pressure on this
motor is only 3 or so psi the plug should hold on it's own.
So I just disconnected the ignition so it wouldn't start and just ran the starter a few seconds. The plug by the oil pressure sensor popped off and shot oil
across the floor. Nothing from the side connection.
I removed the plug from the side gallery connection and tried the plug on the sensor again. The sensor side popped off again and nothing came out of the side connection.
Next I tried just connecting the two connections together with a hose. Now everything works normally.
So I guess these connections are not common to the gallery in this motor ? Seems I have to use the hose to get oil into the rest of the engine.
I missed your pics after your PM. I was looking for a new post. The one I have I'll send to you for postage but chances are the PO blocked off the port going into the oil galley. (commonly done) I suggest taking it off and looking. If so remove the blockage and get a gauge kit or male threaded plug for the inspection port on the side. Yeah 3 psi is the running pressure but with these pumps it will build pressure until it blows or breaks something. (no relief valve)
So what you are saying SWest is that when the oil cooler was installed they blocked off the oil gallery from under the pressure switch
housing and rerouted that oil through the oil cooler and back to the side gallery plug ?
What would that plug look like and how do I remove it.
I can't find a picture of what under the pressure switch housing would look like normally.
If there is a plug in there Steve it would have to be part of the oil cooler installation.
This does look to be an aftermarket installation.
I guess I will have to do some searching for oil cooler install procedures.
