Air conditioning unit on New Holland tractors TM140 and TS110

[mac_J]

We have 2 Newholland tractors TM140 and TS110. The airconditioning units have lost their gas charges. I have to fined the leaks and then recharge.

Would like to know if any Engineers on here have experience working on those units, would like some guidance.

Regards

Put some oxygen free nitrogen in the systems and use soap on all r404 the joints,pressure it up to around 100 psi to start with.

if its had a clutch the self sealers rarely work another issue is the trianary switches leak also they dont clamp the pipes very well they chatter and vibrate unfortunatley the nh aint built like the fords with ac like cad says nitro it check trianary and pipework the ts also have issues with the prv on the back of the comps

sorry my computer spelt 404a,mistake 134a is the refrigerant used but ofn oxygen free nitrogen should be used to leak test the joints then when leakage is sorted blow off nitro and vac and charge as per oems recomended wieght,sorry for the confusion.
