N.O.S. Posted October 18, 2016 Share Posted October 18, 2016 Yes - one potential obvious being lack of oil. Only had a cab tilt pump stop through low oil - if this was the culprit in your case, possibly it caused an air lock in a non-return valve?

paulob1 Posted October 19, 2016 Author Share Posted October 19, 2016 we haven't topped it up yet so will have a go at that tonight, its an awkward cuss to check, but we will get it...it does feel like it is pumping air at times... Quote Link to comment Share on other sites More sharing options...

Cab lifters can be a pain, because they are not used very often when you go for them the gremlin is waiting. Quote Link to comment Share on other sites More sharing options...
N.O.S. Posted October 19, 2016 Share Posted October 19, 2016 If it ran out of oil it will probably not lower until refilled with oil as the non-return valves will not unseat. At least that is my experience. If you are topping up oil with cab partially raised, be sure to leave filler cap off until you've lowered it to avoid blowing up the reservoir if it then has too much oil in (reservoir is only just big enough with little spare capacity).

paulob1 Posted October 19, 2016 Author Share Posted October 19, 2016 thanks for the advice, we have her down now, so we will top up with oil today and then see how she goes, she is off for her MOT in a couple of weeks so we need her spic and spam...
