AllService Magazine SEPD0343, 03 February 1997, "New Metering Pump Groups For Steering Control Prevent Oil Leaks". Disregard this article. See the replacement article that follows.Description of Change: New metering pump groups (steering control units) use improved seals, a new end cap, and a spacer to prevent oil leaks.New round cross section o-ring seals replace the former square cross section seals between the sections of the gerotor assembly. The former square cross section seals could twist during the assembly of the metering pump. The o-ring seals are installed with the steering control unit facing up, to eliminate blind assembly of the o-rings.The bolts that mount the end cap and gerotor assembly to the metering body, were changed from 12 point bolts to self-sealing 6 point Torx head bolts.A one piece shaft seal replaced the former three piece shaft seal for low input torque steering units.Adaptable To: The new metering pump groups are direct replacements for the former metering pump groups listed in the following chart.Note: The former metering pump groups can be updated by installing one of the conversion kits listed in the chart.Note: Former metering pump groups, having low input torque shaft seals, can be updated with a one piece shaft seal, replacing the former three piece arrangement.Seal kits to update former metering pump groups are listed in the chart
