FAQ
Q: What causes a hydraulic pump's rear cover to crack around the main bolt flanges?
A: Cracking is usually caused by over-torqueing the mounting bolts during assembly, or by severe pressure spikes from a malfunctioning main relief valve. The RITO 1027131 features reinforced flange areas to help prevent these structural failures.
Q: Does this pump casing end cover come with the required O-rings and mounting bolts included?
A: This SKU includes the precision-machined rear cover itself. We recommend ordering a matching pump seal kit to ensure you have all the fresh O-rings needed for a leak-free installation.
Q: How can we confirm this rear cover matches the port configuration of our specific Hitachi model?
A: You can verify compatibility by checking that your factory part number matches 1027131, or by sending your pump nameplate data to our team to confirm the port locations match your machine.
A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
