Remove the breather filter cap when the engine is stopped and the breather cap is cool enough to touch by hand.Slowly loosen the breather filter cap in order to release any pressure in the oil tank. Be careful of hot hydraulic oil when any lines are disconnected from the components of the power train.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Inspect the O-ring seals. If necessary, replace any O-ring seals.Note: Before the installation of the seals, use 1U-6396 O-Ring Assembly Compound in order to lubricate the seals.
