DeLuxe Engine Priming Tool

Our new "DeLuxe" engine oil priming tool is a super cool item that every Mopar guy should have in their toolbox. Featuring a CNC machined 6061 Aluminum housing with sealed ball bearings, this pops into the distributor hole and holds the priming rod exactly straight. But more importantly, it takes all the pressure off the oil pump rotors. The intermediate shaft in a big block Mopar is designed to "float" above the oil pump gears. Normally it's recommend to check for .050"-.070" of clearance between the hex end (bottom) of the intermediate shaft and the bottom of the oil pump gear during assembly. If there is no space there, and the shaft is bottoming out into the gear, it will press on the gear, causing it to grind into and score the oil pump cover. With a standard priming tool, it's very hard to take the pressure off of the tool when you've got a large electric 1/2" drill hanging off it it. With the adjustable collars on this tool, you can set the endplay exactly where you want it. And the adjustable collars also allow you to use it with any engine type, such as RB, B or even small block engines!
