FAQ
Q: Why is part number 340701 compatible across different brands like Hyundai, Volvo, and Caterpillar?
A: These manufacturers all use the Kawasaki K5V160 main hydraulic pump model in their 30-ton excavator classes. The internal rotating components of the pump are identical, allowing this single kit to fit multiple machine brands.
Q: What installation steps are necessary to ensure the valve plate seats perfectly against the cylinder block?
A: Ensure the positioning pins are aligned correctly and the internal spring washers apply even pressure. The face of the RITO 340701 valve plate must be clean and coated with fresh hydraulic oil before closing the pump housing.
Q: How does this cylinder block handle rapid temperature spikes when an operator breaks through hard rock?
A: The bimetallic bronze liner is molecularly bonded to the steel block to provide rapid heat dissipation. This prevents localized heat buildup, keeping the pistons sliding smoothly even at temperatures up to 115°C.
Q: Can we order this kit in large quantities for a rebuilding workshop, and what is the lead time?
A: Yes, we support bulk procurement for rebuilding shops and parts wholesalers. We maintain a large inventory of 340701 kits, allowing us to offer quick processing and short lead times for wholesale orders.
A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
