80 series, 1HD-FT, RHD.
Compressor seized solid. Internal failure, not the clutch — debris through the system. Full replacement done: compressor, condenser, expansion valve, drier, flush, oil to spec, new o-rings.
Cooling correct, vacuum held.
One problem. Idle drops when the compressor engages. No idle-up at all.
Assuming the idle-up actuator line at the injection pump wasn't reconnected. Anyone confirm the routing on the 1HD-FT — which line feeds it and where it terminates at the pump?
