C 20 P/U 2WD V8-305 5.0L (1985)
SERVICE NOTES:
(Figure No. 3)
The pump body bushing is included in the above pump body assembly, however, the procedure for installing a service bushing has been changed.
Because of the stepped bore in the oil pump body, the bushing is now installed from the rear (using Kent-Moore tool J 34196-12) and fits tight against
the step in the bore.
