A: Mechanics must flush the upper slewing platform completely to clear metal debris before mounting. Fill the gear casing with specialized heavy-viscosity gear oil to the precise mark, ensuring the outer pinion meshes cleanly with the main ring gear.
A: Absolutely. The internal induction-hardened gears are structurally optimized to withstand sudden hydraulic deceleration and clockwise-to-counterclockwise transitions without suffering tooth shear or stress fractures.
A: Count the teeth on your existing drive pinion gear and measure its outer diameter. Send these exact dimensions along with your chassis serial number to our technical department for structural compatibility confirmation.
A: These assemblies use reinforced double-lip heavy oil seals at the bottom shaft output. This design blocks dirt and fine grit from contaminating internal grease, maintaining smooth rotation in arid quarries.
