Part of the Case Repair Manuals.
All 206 pages of this Case F4 Series Engine Repair Manual (OEM #87630273 NA) target one job: rebuilding the F4GE9454H, F4GE9454J, F4GE9484D, F4HE9484A, and F4HE9484C engines in Case backhoe loaders. Inside: page after page of exploded component views covering crankshaft, piston, and valve assembly, plus wiring diagrams and connector pinouts for the complete EDC7UC31 electrical system. You also get a full troubleshooting section covering conditions from no-start to runaway, torque tables split by engine family, and fuel pressure test values for both mechanical and Common Rail injection systems. Torque your F4GE injectors to 55-65 Nm; on the F4HE, bring the M6 injector bolts to 8.15-8.85 Nm before the 75-degree final rotation. Your engine is apart and the right spec isn't on a forum. Bookmarked by section so you search any value, pull it up on your phone, and get back to work.
