cummins engine oil pump

The Cummins engine oil pump is manufactured as an internal gear type (Gerotor) with an inner and outer rotor. The rotor material is powder metallurgy steel with a density of 7.4 grams per cubic centimeter. The number of teeth on the inner rotor in the 6BT model equals 7 and on the outer rotor equals 8 teeth. The outer diameter of the complete rotor assembly in this model is 65 millimeters and the thickness is 20 millimeters. The radial clearance at the tooth tips (tip clearance) in the original sample is set between 0.08 and 0.12 millimeters. The axial clearance between the rotor and pump housing (end play) is 0.04 to 0.08 millimeters. The oil displacement volume per pump revolution in the 6BT model equals 22 cubic centimeters. The KTA19 model features a larger rotor with a diameter of 95 millimeters and a thickness of 32 millimeters. The displacement volume in the KTA19 reaches 65 cubic centimeters per revolution. The pump housing is cast from grey cast iron GCI-250 with a pressure tolerance of 14 bar.

The Cummins oil pump supplies oil pressure of 2.5 to 5.5 bar at rated engine speed. The volumetric flow rate in the 6BT model at 2500 RPM equals 65 liters per minute. The QSL9 model has a flow rate of 110 liters per minute and the KTA19 model has a flow rate of 180 liters per m

Cummins engine oil cooler

The Cummins engine oil cooler is manufactured as a plate type with parallel channels. The plate material is aluminum 6061 with thermal conductivity of 200 watts per meter-Kelvin. Each plate thickness in the standard model is 1.2 millimeters and the spacing between plates is 2.5 millimeters. The number of plates in the 6BT model equals 35 and in the NTA855 model equals 55. The total heat exchange surface area in the 6BT sample is calculated at approximately 0.45 square meters. This value in the NTA855 model reaches 0.85 square meters. The allowable working pressure of the oil cooler is 12 bar and the hydrostatic test pressure is 18 bar. The nominal oil flow rate in the 6BT model equals 35 liters per minute. This flow rate in the NTA855 model increases to 60 liters per minute. The incoming oil temperature reaches up to 130 degrees and the outgoing temperature after cooling drops to 95 degrees. A temperature difference of 35 degrees indicates an efficiency of 82 percent.

The Cummins oil cooler is capable of dissipating 25 to 45 kilowatts of heat from the engine oil. In construction machinery applications, maximum heat dissipation of 35 kilowatts is sufficient for 6-cylinder engines. Marine applications require 45 kilowatts dissipation because engine speed remains high. Generator

Volvo loader L90 and L120 wheel oil seal

The wheel oil seal in Volvo L90 and Volvo L120 is installed at the interface between the wheel hub and the front or rear axle housing. It is positioned outboard of the tapered roller bearings and inboard of the hub flange. Its primary function is to retain differential oil and prevent the ingress of dust, water, and abrasive particles. The inner diameter typically ranges from 110 mm to 160 mm depending on axle configuration. Seal width is generally between 15 mm and 25 mm. Lip materials are commonly NBR or FKM, with thermal resistance up to 120 degrees Celsius. Internal pressure is usually below 0.5 bar, while shaft peripheral speed can reach 8 m per second. The garter spring provides a consistent radial load of approximately 15 to 25 N.

From an engineering perspective, the wheel hub seal operates through controlled interference between the elastomeric sealing lip and a hardened shaft surface. The recommended shaft surface roughness is Ra 0.2 to 0.8 microns to minimize wear and heat generation. Contact surface hardness is typically 55 to 60 HRC to resist scoring and micro pitting. Bearing radial play exceeding 0.3 mm can accelerate leakage and reduce seal service life. Under heavy mining conditions, average seal durability ranges from 4000 to 8000 operating hours.

Volvo loader oil temperature sensor

The oil temperature sensor in Volvo L90 and L120 wheel loaders measures hydraulic or engine oil temperature accurately and transmits data to the ECU and cabin display. The sensor uses a resistive element with ±1°C accuracy and can monitor oil temperatures ranging from -20 to 120°C. It is typically installed in the oil return line to the tank or at the hydraulic pump outlet to capture real-time temperature under varying load conditions. Proper sensor operation is critical for protecting the pump, cylinders, and other hydraulic components, preventing overheating that can reduce oil viscosity and increase wear on moving parts.

For L90 and L120 loaders, oil temperature sensors are supplied with OEM part numbers VOE15153124 and VOE11419485, providing an output signal to the ECU in the range of 0.5–4.5 volts corresponding to temperature.
