Terex hr18 problem

Ok so it sounds like the returning oil can’t get back to tank! Simply when tracking and it slows the returning oil has a blockage or restriction when returning to the tank, by using the dipper it allows a percentage of the oil into the larger half of the cylinder so less oil needs to go back to tank!

What do you think could be the problem then

A blockage.

A blockage.

What the easiest way to solve that

could well have a return line from the main valve block delaminating internally and causing a partial obstruction which worsens in hot oil ..... or a chunk of rubber in a port somewhere ..

Need to check all return lines back to tank!
