Wilson, new hoses do not solve noise problem. I have 27 new lindes I take care of and all 27 make this noise. Have changed the hydralic hoses at the hyd tank and it did no good. These are new units and linde will not own up to it. Noise sounds like cavitation. Its not. Noise happens when using hyd functions. Preformance of the units is ok. Its the noise.Linde warranty department stated they would supply 2 new hoses and thats as far as they will go.They will not pay for labor to replace or travel time. Also to, same customer bought 13 new units 2 years ago and after 800 hours noise starts. The 27 new ones stareted soon as we recieved them. Not sure what was changed in the system but linde should own up to it and fix it. The models are H35. LP units. Cant push for customer to buy a linde when linde wont fix what is suppose to be warranty. Clark, Doosan. They stand behind their units.. I love the Linde trucks. But its bad when they wont fix their flaws.
