Cat D4H LGP and 2 related models specifications

Read the D4H weight as an equipped-machine statement

Cat's standard Series II brochure defines operating weight with the PAT blade, hydraulic controls, canopy, full fuel and operator. Its shipping figure uses a small fuel fill and a different inclusion basis. Neither number describes every D4H with a cab, winch or ripper.

Confirm the fitted equipment before using the standard tractor's weight to arrange transport. The same brochure identifies a turbocharged 3204 engine for that standard arrangement; the engine plate remains important on a machine that may have received replacement components.

A hydraulic sight gauge does not mean every fluid compartment shares a fill. The service schedule separates the implement hydraulic system from the hydraulic tank, and lists each final drive individually. Keep the compartment wording with the quantity.

Ordering hydraulic oil from a complete-system capacity as though it were a routine tank refill can misstate the amount required.

Powershift and direct drive require different fault checks

The original D4H powertrain description traces powershift drive through a torque converter and planetary transmission before the steering clutches, brakes and final drives. Its direct-drive diagram instead shows a separate clutch and countershaft transmission. Both ultimately drive the tracks, but a failure to travel does not identify the same suspect component in both machines.

Establish which system is fitted before applying a transmission diagnosis. Cat's description assigns three forward and reverse speeds to powershift and six in each direction to direct drive. A specification copied from one arrangement cannot identify the other.

Equalizer-bar revisions affect a repair quotation

Cat's equalizer-bar specification presents earlier and later assemblies separately for the identified D4H application. The bearing-installation depths differ between those drawings. The later illustration also notes that some earlier machines use grease fittings where the illustrated arrangement has external lines at the center pin.

Photograph the installed lubrication arrangement and identify the bar version before accepting a rebuild kit or installation dimension. Mixing the drawings would hide a real revision. The document's applicability must match the tractor; it is not a blanket instruction to replace an earlier assembly with the later one.
