Overview – SENSOR-LEVEL (OIL TANK) 193-0566
193-0566 is the oil tank level sensor used on CUMMINS Onan generator sets to monitor the oil level in the engine oil tank and protect the set from low-oil operation. We can supply this sensor as well as the related lubrication service parts, in stock or available on order – welcome to enquire by part number.
Parts Characteristics
The sensor is built to the original mounting and electrical arrangement, with the threaded body and seal matched to the oil tank opening. The sensing element and connector are matched to the CUMMINS Onan control circuit so the level signal is correct. The housing is sealed against the oil and vibration of generator service. As an OEM-spec sensor, it screws into the original tank port without adapters.
Applicable Models & Applications
This oil tank level sensor is used on CUMMINS Onan generator sets where the oil level is monitored by the control panel, including the generator models fitted with the original 193-0566 sensor. Confirm the thread size, probe length and connector style against the sensor removed from your oil tank before ordering.
Maintenance & Replacement
A faulty level sensor shows up as false low-oil shutdowns, missing alarms or an incorrect oil level reading on the panel. Inspect the sensor for a cracked body, damaged connector and leaking seal during generator service. When replacing, drain the oil below the sensor port, remove the old sensor, fit the new one with a fresh seal to the original torque, and refill the oil to the correct level.
Price Reference (USD)
The reference price for this SENSOR-LEVEL (OIL TANK) (193-0566) is approximately USD 60 – 250 per unit depending on grade, quantity and shipping destination. This is a planning estimate only – confirm current pricing and availability with our sales team before ordering.
Value & Service
A sensor with the wrong probe length reads the oil level incorrectly, so we verify 193-0566 against the original CUMMINS Onan tank and connector specification before dispatch. We stock the sensor together with the tank seals and oil filter kit, and they can ship in one tracked order. Our team will confirm the correct sensor for your generator set before you buy.
