Gavster640 Posted February 7, 2020 Report Share Posted February 7, 2020 We have an old Ford 3910H tractor, which we use solely for motorbike events, so probably only does 100 hours a year. Towards the end of last year the usual people who use the tractor were away, and a member of the bike club used the tractor to set the track up. Now for some unknown reason it was left idling for upto 48hours!! It still runs fine but we have a warning light on the dash, we originally thought this was oil pressure, so did an oil & filter change along with the oil pressure switch, which has made no difference. I have attached an image of the light that's on if anyone has any ideas it would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
TIGHTCHOKE Posted February 7, 2020 Report Share Posted February 7, 2020 A Norfolk Specialist known only to me says; someone is running a post “Ford 3910”...............tell him it is not the engine oil light but the hydraulic oil light 1. the oil needs changing and the filter 2. it needs topping up Quote Link to comment Share on other sites More sharing options...
john deere Posted February 7, 2020 Report Share Posted February 7, 2020 Transmission oil overheated. Quote Link to comment Share on other sites More sharing options...
Old Boggy Posted February 8, 2020 Report Share Posted February 8, 2020 The oil light is the back end oil ......... The gearbox ........ and the hydraulics and the back axle all share the same oil. Top it up with "Universal" oil. Check the dipstick and the light should go out. How do I know all this technical stuff ? I got it second hand via Fat Sarah.

Westward Posted February 8, 2020 Report Share Posted February 8, 2020 I heard Fat Sarah knows quite a lot about dipsticks but it might be just a rumour. Quote Link to comment Share on other sites More sharing options...
