Case puma Auto difflock problem

[Drillman]

The Auto difflock on our puma isn't always staying engaged. I am fairly certain its down to the steering angle potentiometer being in need of adjustment or cleaning. How do i go about this?

A exploded diagram would be helpful if anyone has one.

Cheers

Normally a error code comes up when steering angle sensor faulty.

Check your brake pedal switches are working properly.

Probably just needs EMU calibration, be a similar procedure to your TMs, hopefully in the book. My 155 was a pig to turn at one end when ploughing, found that diff was staying in when turning one way, because it didn't know where straight ahead was. Cal sorted it. It does still play up at times but that's because the radar has a habit of telling it that we're going at 100mph and the diff drops out. Have to disconnect it when buckraking to avoid embarrassment.

No error codes. If i steer slightly left hand down it works. fine, If i go straight or abit right hand down it drops out.

The wire going to sensor can sometimes get broken at the top of the axle, just off the the right hand side of centre if I remember correctly

The manual says the dealer can adjust the amount of lock at which the diff disengages yours could be set to sensitive I imagine it's a laptop job

It's calibration we had the same thing on a T7.200. I think the dealer has to do it unless you have the plug that goes in to the cab pillar.

There are three settings for when the auto diff drops out, laptop job to change it. I had it done on my T7.210 as I was fed up off trying to plough with only one wheel driving.

Not a laptop job, you ideally need the diagnostic plug but you can do it with a jumper wire.

Fair enough. He used the laptop when he did mine.

Unless the Case is different to a NH? You can do an awfull lot with the diagnostic plug to be fair!
