Newholland Hydro Overheating CX820

[Mafarmer]

Hi,

We have a CX820 combine that overheats its hydrostatic oil when on the road or pushed hard in the field which causes it to shut the forward speed down. The cooler has been cleaned out, all oil and filters changed.

Local dealers don't seem to have any ideas. Has anyone on here had anything similar. Any advice much appreciated

Thanks

Cooler cleaned how, and what actual oil temps have you recorded ???

Is there a gauze filter on my cx8030 where the pipe goes into the oil cooler. Maybe worth a check is not already. Assuming it's the same on the older ones.

Cooler blown out then washed using coil cleaning detergent. Not recorded temps but temperature hits transmission de-rate threshold. Thanks

Thanks @JJT I will take a look

Is the oil actually hot or is the sensor goosed and showing a false high?

Agreed

We had a problem with a pressure relief valve on a TX64 blowing off at a lower pressure than the system runs at. This was on the hydraulic side but the overheat on a TX is for both hydraulic and hyrostatic.
