Re: Crossbred, 454 into an '85 Ram

The crank has been install and all the clearances checked. Also installed was the rear main seal, which i offset a bit (can't hurt and i have always done it). I also put some anerobic sealer under the #5 main from the rear seal out to the edge, this keeps any oil from seeping under the cap and causing a very hard to diagnose oil leak---hopefully there won't be any of those however. For those that do not know, an anerobic sealer only dries in the absence of air--such as between two tight fitting metal surfaces (such as a main cap and block--or on more modern manual transmission case halves). I also cleaned the crank with a can of brakleen and a small brush from my engine brush set to get into the oil holes. I thought i had it fairly clean already, but those brushes really pull some junk out. Always clean it the best you can.


Crank installed on bearings dry. Getting ready to check with clearances with plastigauge




Here is the #3 main cap pulled and bearing clearance being checked. My clearances ended up at .003" for #1-4 mains and .0035" for the #5 main





Torquing the main caps in place, i gave the crank some light taps back and forth to seat the thrust surface on the main cap before tightening.





Checking the endplay of the crank. I know the picture isn't great, but i ended up with .008" of endplay is what it's showing on the indicator.
