Cat Lift Trucks (& Caterpillar) EP16KT:
Hydraulic Fluid Frothy After Being Stood Overnight

Hi There
We have a EP16KT and its fine during the day onece it has been used a few times but in the morning when we go to use it again the oil gets throthy.
The steering also makes a loud whining noise until the froth has gone.
we usually lift the forks up and down (lowering slowly) around 20 times and then all is good for the rest of the day.
weve changed the oil and filters recently.
we do notice oil under the middle back wheels in the morning but we think this is coming from the overflow pipe and is just surplus oil that has throthed over.
any ideas greatly appreciated

think you need to pull the battery out, clean all the corrosion out, change the main suction line to the pump and also closely eyeball all the other hoses, including the power steering pressure lines, looking for any place a bit of hose has rubbed through, or gotten "spongy" from battery acid. also check for loose fittings including any fitting with an O ring.

I would check the suction hoses and clamps on both pumps. Maybe when it is cold air is getting sucked in but once it warms up a bit the air leak stops.
