1070 no reverse

Barker Farm · Jan 21, 2012

This is going to be kinda vague, I am doing this for my father in law not having seen the tractor.

Over the summer stopped driving entirely, was found to be a cracked torque plate. This did nothing for it. Split it again and shimmed something. This got the forward gears to work fine, but it still has no reverse.

Any help would be greatly appreciated.

Thanks

I guess that the shift lever is going into the R position but it just don't move, is that right or is the lever being kept from R position? Pressure readings are essential for diagnosing the shift problems in these tractros. Actually would be ideal if you had a 4 gage setup to put in the valve pressure check ports on top of the tranny, when you get ready to do a hands on let us know, Of particular interest is the C2-C4 combination which makes up reverse and also clutch down which is a tranny brake function. We are looking for a C4 problem as all other clutches are involved in ranges that you say work fine. There are several on forum who know this system well and all will respond with their own thoughts.

What pressures would the gauges need to go up to? I can probably get a set of 4 that are good for 600psi.

What thread are the test ports?

The test ports are 1/8 pipe and the working pressure is 180-210 lbs so 600 lb gages would be fine. A factory setup would have the gages mounted on a bar with long enough hoses to sit in the seat and work the clutch and shift ranges. Once you have the gages in place, write the pressures you see in each powershift range including clutch down and reverse on a sheet of paper then get back to us. mEl

This can all be done with the range in neutral so it doesn't move?

Yes, 4 speed in neutral, the power shift is a seperate unit from the main tranny and it does not make any difference in gear or out. mEl

I guess I will also need to know where the test ports are located.

Under the floorplate on the top of the powershift valve cover.

Just an update will hopefully be doing the pressure check this weekend
