Ford New Holland 8670 Common Problems This Manual Covers
New Holland 8670 remote valve leaking, can't identify the correct seal kit part number
Check the hydraulic parts diagram and match the leaking valve to its exploded view. Pull the seal kit number from the parts number list, then verify it against your serial number range. Measure the old seal's outer diameter to the nearest 0.5 mm before ordering.
Manual Section: Hydraulic SystemTransmission input shaft bearing rough, not sure which bearing and snap ring to order
Remove the old bearing and measure its outside diameter in millimeters with a micrometer. Match the input shaft assembly in the drivetrain parts diagram, note the callout numbers, then confirm both the bearing and snap ring part numbers in the parts number list before ordering.
Manual Section: TransmissionSteering cylinder leaking again after a rebuild, need the complete cylinder assembly number
Check the chassis parts diagram for the steering cylinder exploded view and note the assembly callout. Confirm the number in the parts number list against your serial number range. Measure the rod diameter in millimeters and check for scoring; a scored rod won't hold new seals, so order the complete assembly.
Manual Section: Steering SystemHeater and AC hoses cracked, can't match hose assemblies to catalog callouts
Inspect the cab and interior parts diagram and trace each hose to its callout number. Verify the assembly numbers in the parts number list. Measure the inside diameter of each cracked hose in millimeters and compare when ordering, since heater and AC lines look alike once the insulation is off.
Manual Section: Air Conditioning/HeatingCatalog lists metric hardware but only inch wrenches and thread gauges on hand
Measure the screw diameter and length in millimeters with calipers, then convert using the metric to inches table on page 494. Verify the callout against the exploded view before ordering; mixed hardware on older units is common, so check every fastener individually rather than assuming one size fits the whole assembly.
