Gday Guys first time posting, from Australia in need of help, I have a hd16dc with s/n 6172 and engine s/n 16-05291, First problem I have is no clutch or brake power on left side, problem two is the oil in the torque converter tank is milky but not watery more of a condensation build up I think,
But the oil in the tank at the front near bottom of radiator is good, are these two tanks connected? We changed the oils when we got the machine,which didn't fix the problem, plus now the blade and ripper don't lift, no Hydraulic functions, is there a way of testing the hydraulic pressure and pumps?air in the system maybe, if so how to bleed, appreciate any help, don't know much about these machines.

Tank in front is Tools, Reservoir to rear is Trans/machine operating controls supply, totally separate. Unless did not get fully filled should have self bled air as have Positive Displacement Pumps. Filters been changed? Steering was there prior to drain and refill?
