Hydraulic help cat 65

Hello my 65 tractor was used for planting folded up the drill drove up the road 10 miles I have no hydraulics on any four of my levers I've tried a couple different ones at the same time nothing happens the reservoirs are full No fluid on the ground no fluid in the frame area need help locating the hydraulic pump location does this model have two pumps on it. does anybody have any input or any help that would guide me in the right way

Difficult to provide info without a Serial Number. There are half a dozen different models of 65.

Ok when i get home i can find that This is 65 only no letters

Had alot of rain an sorry i did not get time for serial number

From what I can see it only has one hydraulic pump. Do you have gauges for testing pressure.? This is a piston pump and the pressure testing procedure is not a simple job because it requires an understanding of how the pump and the circuit operates. My first suggestion would be to remove the hydraulic filter and cut it open to look for debris. If the pum[p has grenaded that's where you'll find the shrapnel. Someone's going to need the Serial Number at some point because there are different test procedures depending whether the Serial Number is above or below 7YC1900.

It has been awhile

7yc00726

Is it still broke.?

Harvest season is here. Is the 65 still broken? Will the soybeans ever get harvested?

You're going to have to do some fairly involved testing on the implement hydraulic system. How well are you set up for pressure gauges, etc.? You will also need a differential pressure gauge. See the attachment. Start at Page 8 with the "Pump Compensator Tests" for:-

1. Low Pressure Standby.
2. Margin Pressure.
3. High Pressure Stall. Don't try to adjust anything at this point in time. Just do the testing and come back with the results.

I'll have to check with the boys that run the tractor shop in the next town over .. have you every see or heard of the pump just stop working? Does the 65 only have one hydraulic pump that runs the implement side? And is the hydraulic pump located on the left front?

See the attachment for an explanation of how the implement hydraulic system works. Question: Have you removed the hydraulic filter and dut it open looking for debris yet.? If you haven't it might be a good idea to do that before anything else. See this VIDEO

• I know it's for an engine oil filter but the principle is exactly the same. Post photos of anything you might find.

My guess is the compensator has failed, or one of the 3-way checks that controls pilot pressure to the compensator. The hydraulic pump in mounted to the front of the transmission, top left side.
