This Case factory service manual covers the Alpha Series Tier 4A SR220, SR250, SV250 and SV300 skid steers and the TR320 and TV380 track loaders, with both mechanical and EH controls.
It covers engine removal, EGR and DPF aftertreatment, the chain drive and the hydrostatic pump and drive motors. It also covers the loader valve, enhanced high flow, quick coupler, rubber tracks and cab climate. For the wiring there are schematic sheets, connector views and fault code tests.
A job usually stalls for want of one number: the relief setting, the track sag or how much oil goes back in. Print it, so the pages can go to the bench and get dirty.
