utvolman99 Posted March 1, 2004 Share Posted March 1, 2004 Okay, this is a little hard to admit but this is my first Chevy build. When installing the camshaft what holds it in in the front and back? It looks like there is nothing in the front except for the timing gear? There is no place to bolt anything only three oil channels. In the back there is a silver plug (kind of like a feeze-out plug but not as deep and bigger around. Is this the cam wear plate? Is this all that holds the cam in? Also, which direction does the back plug wear plate dudad go? I have it in like a normal freeze-out plug but a friend of mine told me that it is suppose to go in lip first? Thanks for your help!

dmyntti Posted March 1, 2004 Share Posted March 1, 2004 On flat tappet lifters nothing the cam is held back by a slight taper on the cam lobes. This causes the lifterts to turn and also holds the cam back in the block. If you use a roller cam then you need to use a cam button on the front of the cam that pushes against the timing chain cover to hold the cam in place. As I recall the plug at the rear of the block is installed just like a freeze plug. Quote Link to comment Share on other sites More sharing options...

I guess there is not a huge amount of stress on it though. Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted March 1, 2004 Share Posted March 1, 2004 the rear cam plug is chevy part # 10241154, its instalkled cup sid out and I normally use a small amount of hard set sealant on the outer edge and use a punch to lightly lock it in place the cam button installed in the cam gear is a great saftey item and dirt cheap! leave about .015 clearance between the cover and the cam button http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=2680&prmenbr=361 http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=2667&prmenbr=361 Quote Link to comment Share on other sites More sharing options...
80LS1T Posted March 2, 2004 Share Posted March 2, 2004 There's no cam button on an LT1 is there? I dont recall seeing one when I rebuilt my engine? It did have a plate with 2 bolts that held the front of the cam from coming out of the block? Would that be the same purpose as a cam button?

wheelman Posted March 2, 2004 Share Posted March 2, 2004 80LT1, You're right about no button on an LT1. The cam has a ridge machined on the front and uses the retainer plate you mentioned. Wheelman Quote Link to comment Share on other sites More sharing options...
