Article 97-2-16 is being republished in its entirety as part of a consolidated 7.3L diagnostic aid booklet.
A high number of high pressure Rexroth pumps and Injection Pressure Regulators (IPR) are being replaced due to oil leaking, when all that is required is a new gasket or seal on either the pump or IPR.
If a suspected oil leak is being observed from either component, replace the pump gasket with new gaskets. Pump or IPR replacement is not appropriate for an oil leak. Any pumps and/or IPR's returned must have location of oil leak noted on the diagnostic form which must accompany the returned part. Refer to the appropriate Service Manual for specific details.
