Part of the Case Repair Manuals.
You are about to tee a gauge into the loader valve or unbolt the SCR catalyst on an 821F or 921F. This is Case service manual 84487565, 1st edition, April 2011, for the Tier 4 wheel loaders.
Tracing an SCR code or a weak lift circuit without specs is how a half-day job turns into a week. This book has the pressure test points, the fault code tables, the removal steps and the fold-out electrical and hydraulic schematics for both models.
Print it. You can take the pages to the bench, get hydraulic oil on them and still read the wheel bolt torque off page 794.
