Product Description
Cummins 69550 plain Woodruff key for compatible 855 and NT855 Series diesel engines. Designed to secure the camshaft gear or accessory drive components to the shaft, helping maintain proper alignment and prevent rotational movement between mating components.
This straight, non-offset Woodruff key features a nominal 1-inch diameter and 5/16-inch width. Used in select Cummins camshaft timing gear and accessory drive assemblies.
Related parts include Cummins 3021601 and Interstate-McBee M-69550. Cummins 3021601 is a shorter 3/4-inch timing-equivalent key and should not be substituted without verifying the required dimensions.
Cummins identifies 69550 as a plain Woodruff key for 855 engines and publishes a shipment weight of 0.03 lbs. FP Diesel's catalog identifies it as a 1-inch camshaft gear key. The 3021601 reference is a shorter timing-equivalent key, not an identical dimensional replacement.
Verify engine model, serial number, keyway dimensions, and original equipment part number before ordering. Sold individually unless otherwise specified.
