2390 oil suction screen

Ranchingelec · Apr 15, 2013

Do you have to split the tractor to clean or flush the oil suction
screen or is there access through any of drain plate or shift
housing? Got no pressure after the charge pump.

To do a good thorough cleaning the tractor does need to be split. However one can get most of the debris by removing the PTO unit and then fabricating a long thin suction tube approx. 5 ft. long. and carefully going from the rear and sucking the junk off the screen. It is not easy and you won't get all of it but it is possible to get it clean enough that the hyd's work properly. This does correct the problem, where did the debris come from. Repair the area that is faulty, sometimes you have to split the tractor anyway, Rod.

Also don't be to quick to blame the suction screen, the charge pump can be faulty, Rod.

Rod: I also removed the pump bolted to the tractor belly, & the shifter control from the right side. We fed a hose back from the pump suction to the center of the screen & blew back, and also got another angle to clean from by using the shifter control opening.

We jack the front of the tractor up as high as we can. Remove the pto and side shift cover. I have a fuel pump that we restrict down to shoot a stream of diesel fuel. We flush the diesel thru the shift cover hole and from the rear many many times. Some lower pressure air on a stem will help knock some of it loose so it will flush out also. Thad

John that's a very good point and the shifter cover is another place to access the screen. Around here all the rear wheels are set in to 30 inch rows making it difficult to squeeze between tire and housing so I find myself trying to do the clean up effort from the rear. The old saying there's more than one way to skin a cat, applies to this also, lol. Rod.

You have been some good advise from the others.

If the problem is the screen then more than likely you have another problem.

I’m the guy that replaced the oil in a cherry 1370 only to have the oil dissolve the glue right out from underneath the fiber disks.

The oil I used was something other than Hytran

I split the tractor and cleaned it out but in the end I also pulled the PTO housing and took a long steel brake line tub that I bent a half moon shape on the end so I could blow the screen clean.

I also washed the screen with a flood of diesel fuel.

You will have to do this several times because the amount of fiber is so great it will plug you off if you leave a little.

You can also blow the screen free by installing a tire type screw in valve at the filter pressure port.

This will allow you to run the tractor at idle for a short amount of time before the screen plugs up again.

I have cleaned the screen by jacking the front of the tractor up, remove the charge pump, pumping diesel fuel through the center of the screen and flushing it from the inside out. You can remove the side cover and pto if you would like. I have also removed the side cover and used a long screw driver to punch holes in the upper part of the screen so the fiber from the discs could get caught by the filters.
