Introduction
This guide shows how to remove the oil pan on a Honda HRS216K6 lawn mower to access internal engine components.
Drain the fuel from the fuel tank before you begin this procedure. Any fuel remaining in the tank will spill out. Be ready to contain any spillage.
Drain the oil from the motor before you begin this procedure. Any engine oil remaining in the motor will spill out. Be ready to contain any spillage.
You will need to refill the engine oil after this procedure. The lawn mower requires up to 0.55 liters of SAE 10W-30 oil.
You will need to reapply liquid gasket after this procedure. Use ThreeBond 1216, Hondabond HT, or equivalent.
You may need a blowtorch to help heat up and loosen the flywheel.
