Hola a todos, mi consulta sería sobre los "wells" de los brazos hidráulicos, es un texto sobre camiones de reciclaje y su mantenimiento. Entiendo que "wells" podrían ser "pocillos" pero en este caso no aplicaría.

Contexto:
Clean equipment windows for unobstructed views.
Remove build-up of materials within engine compartments, including around the radiator, transmission, & base/belly pan.
Clean the equipment cab & ensure there are no loose objects that could obstruct operation.
Remove debris from hydraulic arm wells.

Muchas gracias!
