Ford 8630, 8630 6 CYL AG Common Problems This Manual Covers
Ford 8630 hydraulic lift cylinder leaking at the rod end, can't identify the correct seal kit part numbers
Check the hydraulic system exploded view and match each seal to its callout number. Verify dimensions before you order: the check plug seal measures 59.85mm and its O-ring 63.5mm, both listed on page 303. Cross-reference the callout number in the parts number list against your serial range.
Manual Section: Hydraulic Lift CylinderHydraulic pump plugs look nearly identical, can't tell the check plug from the center plugs when ordering
Measure the plug diameter before you order. The check plug housing and dome center plug both run 63.5mm, while the flat center plug measures 59.85mm, all listed on page 302. Match your measurement to the correct callout in the hydraulic exploded view, then pull the part number from the parts number list.
Manual Section: Hydraulic Lift Cylinder p. 302Hydraulic hoses weeping at the fittings, caliper reads metric but some parts listings show inch sizes
Measure the fitting and hose dimensions in millimeters, then convert with the metric to inches table on pages 538-539; 63.5mm, for example, works out to 2.5 inches. Trace the hose run in the hydraulic exploded view and confirm the part number in the parts number list.
Manual Section: General Infomation - Metric to Inches p. 538Parts list descriptions packed with abbreviations, hard to confirm which seal or plug the line describes
Check the abbreviations list starting on page 524 whenever a parts description reads unclear. Decode the line first, then confirm the dimension against the spec pages; a check plug seal, for example, measures 59.85mm per page 303. Verify the callout in the hydraulic exploded view before ordering anything.
