📩 Customer Note
Please verify part compatibility with your specific tractor model variant, hydraulic line configuration, and chassis serial break numbers before purchase. Flushing the entire hydraulic oil reservoir system and installing fresh filters is strongly required when replacing a main gear pump to prevent trapped metal contaminants from scratching new internal gear faces.
