Hi Dan, A simple check to start is to attach an implement that the system will not lift at the moment. Remove the top link and attach a chain or similar between the implement and a pin fitted through the 3 lugs on the rear centre housing. Ensure that the load is taken by two of the lugs. Don't use the top link attachment point. If there is a problem there it can cause the system to move towards 'neutral' when it should be lifting. If it lifts OK with this test then the control spring assembly will require attention. If there is no improvement check the tightness of the 4 13/16" nuts on the top of the hydraulic cover. If all are tight drain the oil back to the level of the bottom bolt on the RH round side cover. Remove the cover and using a flashlight look upwards inside for any sign of oil falling down when the system is in 'lift'. Let us know what you find. DavidP, South Wales
