Subject: RE:What tool did you use to prime your LT1 oil pump? by Slalom4me on 2008/2/21 3:43:43 biggrizzly, the shaft you provided a link to is the shaft that transmits motion from the stub shaft or distributor to the pump. It has a collar at one end and a female tang at the other - it is not what you want. Quote: They make a tool for priming Gen 1 SBCs. I am unaware of anyone Actually, if the LTx intake is removed, along with the stub shaft that is used to drive the pump from the dist gear on the rear of the cam, then a large flat blade screwdriver can be turned by hand to prime an SBC oil pump. With enough wrist action, oil will flow to the galleries and bearing faces. The catch about using a screwdriver or one of the aftermarket shafts that do not include collars is that no oil will be pressurized through the passenger side lifter gallery - normally the lower portion of the LT1 stub shaft or the bottom end of a Gen 1 conventional dist housing seals the hole in the valley that receives the dist housing. This vertical hole intersects with the pass side lifter gallery. The collars on the better pump priming tools act to seal the leak at this point. A cord or cordless drill with some power will spin the pump and you should expect to see good pressure displayed on the dash gauge. ARP #130-8802  Proform #66896  . |
