Cheers lad. Ploughing with it at the minute. Just when I was moving fields der it kept goin into neutral. Wood it be OK ya think to finish out to day.. I don't nó much about the cases or nh.,I've just remembered there's also a dump coil on the 50k valve block to make sure it's not dragging when your in any other gear, this could be sticking and dumping pressure out of the pack.
