No lift after rebuild Farmall Super A

[Logov76]

Hello I am new here I was looking for some advice I just rebuilt the touch control and pump on my farmall super a. After solving a no spark issue I cannot get hydraulic pump to prime I would check pressure on manifold but I cannot get the check plugs lose. I am pretty certain that I put all the valve of back correctly on touch control and the pump was working before resealing it any advice would be appreciated

Thanks

try putting oil in the lines so the pump is not dry

I should clarify I primed pump before installing and filled reservoir with a nipple in the fill hole and funnel to get oil in the lines so I know for a fact there is oil to the pump is there some kind of bleeder screw than I can take loose on the pump or do I need to get the check plugs out on the manifold?

if it has oil and does not work I would put a gauge in the line to see if the pump makes pressure, no or low pressure pump issue, good pressure touch control issue

I know there were multiple pumps used on the Super A. So I'm not sure how much of the following will apply in your specific case. However, there are mistakes that can be made in assembling a pump that will give you this problem.

Take a look at this post (and the surrounding thread).

So I put a gauge on and I have fluid movement but no pressure

Check the orifice and orifice screen for trash. You can access it through the pipe plug in the head.

So after messing with it I tried using a hydraulic power pack that I have and pumped directly in pressure port and it is dumping straight to the reservoir. I will pull apart soon but is there any valve that may cause this? The only other thing I know is the two bleeder style plugs in the bottom I had one fall out as I was removing the cover so I had a total of three the two in the bottom were still in place I assumed whoever was there last lost that loose one in the reservoir

Any more suggestions?

Does anyone have the service manual for touch control?

[Jim Becker]

It is in the PDF manuals. Use the quick links at the top left of this page. Then go to: "Service Manuals" then to "Blue Ribbon Service Manuals".

Update tractor is working I removed lift box and checked with air and found I had control valve sticking for front lift but was not my no lift issue. After referencing hydraulic pump manual found that spring plate behind pump bearings was stuck and after cleaning and reassembly works great thanks for all the help
