Torco MPZ Engine Assembly Lube Tube - 12 ounce, (Case of 12) is favored by professional mechanics for assembling many internal mechanical components including wrist pins, pistons, bushings, plain bearings, ball bearings, roller bearings, journals and transmission components. The MPZ EAL is a high viscosity, oil soluble lubricant which contains a concentrate of anti-wear, anti-friction and anti-shock chemistries featuring the highest degree of protection. It has excellent adhesion properties and will slowly run and drip leaving protective film on treated parts. In engine applications, it is recommended as a pre-lube for valve train parts, wrist pins, rod bearings, main bearing, etc. In driveline applications, it is recommended as a pre-lube for gears, bushings, roller bearings, ball bearings in manual and automatic transmissions, transaxles, transfer cases, rear axles and marine v-drives. It protects assembled engines, transmissions and rear axles from rust and corrosion during storage and shipment to vehicle assembly plants.
