1 Oil capacities are based on filling from dry condition. Less oil may be needed depending on emptiness of oil reservoir(s) after draining. Always fill the gear housing until oil drips out of the oil level hole. Replace plugs in their respective holes. Following this procedure will ensure proper oil level.

2 Gear End amounts apply to all CP Series blowers.

3 Drive End amounts apply only to Splash Lubrication models.

* Maximum conditions based upon 70°F (21°C) inlet temperature and 14.7 psi (1 bar) absolute inlet pressure.
