Found some extra parts in Doosan Solar 340 LC

Found these behind the seat. They are 20mm diameter, 40 mm high. Are they relief springs?. All functions work great except bucket curl is a little weak. Thanks

They look like the brake springs from inside a travel motor or slew motor.

Good day
Maybe spool springs.
Kind regards
