Hi guys.
Last night my operator called that the hyd oil was low as it had cavitated when he was pushing up a pile. This is a D8N 9TC02252.
It was fine in the morning and after seven hours it had lost 45 L. It was dark but we could see it dripping from a stump pan. The transmission oil was also over the full mark which was puzzling.
This morning we dropped the pans and turns out the leak is from the diagnostic port on the lubrication supply line to the left side of the flywheel housing.
Great this is an easy fix I thought for about 5 seconds before I realized it was leaking transmission oil.
I have since come to the conclusion it is leaking hyd oil into the transmission and that this transmission oil leak is totally unrelated.
Am I correct in thinking that the only places it could leak hyd oil into the transmission is either the hydraulic pump or the steering motor?
Is there any way without bench testing the pump and steering motor to narrow it down which is the issue?
All the hyd circuits are working fine otherwise.
Thanks.
