We have a couple of good updates for you. This update will focus on swapping out the low pressure 1962 Corvette Oil Pump. The following one will focus on the jack modification.
When we did this before it was pre-website. After reading this you’ll feel like you’ve done this yourself.
After removing the exhaust cross-over and the oil pan, the oil pump is exposed. One bolt and a set of pins hold it in place.
On the left is the Corvette’s oil pump, on the right is a new pump. We don’t want to install the new pump, we just want the pressure regulation spring from it.
Here is the pressure regulation spring. The stronger the spring, the higher the oil pressure. The spring is retained by the pin shown.
To remove the pin, the four retaining screws that hold oil pump pressure regulator housing need to be removed.
Here is the inside of the the oil pump. Access to both sides of the retaining pin allows to pin to be driven out with a pin driver.
The pin is easily driven out with the driver and a hammer.
Once the pin is driven out, the pressure regulating spring will pop out.
Here are the springs from both pumps. On the right is the spring that we clipped for the PV that gives a lower oil pressure. On the right is a regular oil pump’s spring.
To reinstall, the pin is set back into place, and the spring is held in place with one of the drivers. The pin is tapped back into place to retain the spring. The pump is then reinstalled along with the oil pan and exhaust cross-over.
