What to check before ordering WP12 parts
Confirm the engine model and serial number from the nameplate, not only the machine model - the same truck can carry different ratings.
Measure the liner bore, piston crown height and crankshaft journal sizes before ordering a rebuild set.
For overhaul work order the full kit: liner kit, piston and ring set, bearings, gasket set and valve train parts together, so tolerances match.
