I have what I believe is a Case 530 AG (no serial number) with a model 31 backhoe (#4041946) and model 31 loader (#4048518). So beginner mistake I loaded a large rock in hoe and panicked when swinging downhill and managed to break the trunnion socket on the swing cylinder. You can see the damage in this video https://www.youtube.com/watch?v=nsyQIlXK0aQ at 6:30 minutes. So is that piece available? Do I need to replace the complete cylinder? Where would I find the trunnion socket or cylinder (part #D25025 or D27750). Do cylinders from a model 32 fit? Is this totally operator error or is there something I need to adjust. Thanks Ron
