Bolt O-ring flange for Terex PT80

The 2035-298 flange bolt with O-ring is a specialized fastener used in the undercarriage assembly of Terex PT80 compact track loaders, specifically for units with serial numbers DTI 01310 and later. This component is engineered with a socket head and an integrated flange designed to accommodate an O-ring seal. The bolt features a 5/8-18 thread specification, indicating a 5/8-inch diameter with 18 threads per inch.

This fastener serves a dual purpose by providing mechanical fixation and maintaining a sealed connection in areas where fluid containment is necessary. By compressing the O-ring against the mating surface, the bolt creates a seal that prevents fluid leakage and keeps external contaminants from entering sensitive undercarriage components such as bearings. Proper installation of these bolts ensures the integrity of the undercarriage system, maintaining the required pressure and lubrication levels during machine operation.
