K3V112DT pump leaking from the housing or bearing seat damaged on your R210-7? A cracked or worn K3V112DT pump housing allows oil to escape the casing and loses the structural support that keeps the shaft bearing concentric. RITO supplies this Tong Myung pump housing to restore sealed, structurally sound K3V112DT casing on your Hyundai excavator.

In StockK3V112DT Pump Housing (Casing) for Kawasaki K3V112DT piston pumps on Hyundai R210-7, R210LC-7, R215-7 and R220-7 excavators. The pump housing is the structural backbone of the K3V112DT: it positions the rotating group, mounts the regulator and swashplate assembly, and seals the case-drain circuit. Precision-bored bearing seat and machined seal grooves maintain the alignment and sealing integrity required for long-service K3V112DT operation.

Shaft bearing seat machined to OEM H7 tolerance, maintaining shaft concentricity that protects the K3V112DT rotating group from the deflection loads that accelerate barrel and piston wear.
All O-ring seal grooves machined to OEM dimensions for correct seal squeeze, preventing case-drain leakage at the housing mating faces under K3V112DT operating pressure.
Regulator mounting boss and swashplate trunnion bores machined to OEM position, ensuring correct servo geometry after housing replacement without shimming or adjustment.
Housing geometry confirmed for K3V112DT pumps on R210-7, R210LC-7, R215-7 and R220-7 for direct assembly inside the existing pump without machine modification.
FAQ
Q: When should I replace the K3V112DT pump housing rather than repair it?
A: Replace when the housing has stress cracks propagating from the bearing seat, bearing seat bore is oversize beyond OEM service limit from spinning outer race, or seal groove dimensions are out of specification from previous O-ring failure.
Q: Can I reuse the old K3V112DT regulator and swashplate with the new housing?
A: Yes if regulator and swashplate components pass dimensional inspection. The new housing is machined to the same OEM mounting geometry, so existing serviceable components fit directly.
Q: What O-ring material is correct for the K3V112DT housing seals on R210-7?
A: Use FKM (Viton) O-rings rated for hydraulic oil at 100 degrees C or above. Refer to the Hyundai R210-7 service manual for the exact O-ring size specification at each housing joint.
Q: How to confirm this K3V112DT housing fits my R210-7?
A: Confirm the pump model is K3V112DT and the machine model is R210-7, R210LC-7, R215-7 or R220-7. Provide the pump serial number to our team for cross-reference confirmation.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
