Crown RR5700:
Carriage drifts up when reach is extended or retracted

The MTC handle has been recalibrated with no effect. Fluid level is good. No debris in the filter. Pulled valves from the main manifold but found nothing obviously wrong. Had suspicions about SCby so it was swapped out but no improvement. PCA, PCL and PVA were changed out as well with the same results. There's no external signs of cracking of the manifold but could it be leaking internally?

Replace handle base, that's most likely the culprit.

try checking for broken or shorted wires in mast and reach assembly. Have seen that happen before on RD5200
