howdy ya'll

so i finished my top end rebuild, new cam(261 C) and timing chain replacment only to find i think my timing chain is 1 link off on the bottom crankshaft sproket. i tried firing her up and it dident even sound like the valves were opening. my manual told me to line up the dowel pin on the cam at 12 o clock and the top chain sprocket at 12o clock. but my top sprocket looks like its in the 1 o clock position.can i just pry on the tensioner and try to jimmy her over a link. or must i take off the timing chain cover?

thanks mike
 
so i decided to quit messing around trying to move it over a link and take the cover off and am replacing the gasket again today as the 3 day old one ripped. i tried for a while to try n move it over a link but the guides press it in towards the sprocket. it's sure frusterating having to go back and do things twice:bang:. i spent alot of time droping the axle to replace the oil pan gasket,and it ripped off with the cover. my confidence level is dropping quick. i guess hoping for a flawless start up is only a dream for first timers.

advice to other: dont blaze and work on your truck.
especially if its your first time.:whoops:
 
dont blaze and what? wheres my 17mm? where the hell is my 17mm? oh wait its in my pocket. I forget what I was doing. been there done that. Suggestion: take your time, when you rush its easy to forget things and make stupid mistakes. Its better to do it right once even if it takes you twice as long, because if you do it again you wasted however much time it took to screw it up in the first place.
now onto the engine: do you think the block or head has even been shaved or planed? if it has this shortens up the distance between the crank and cam sprocket, therefore your effective chain length is shorter, so your cam timing will be retarded unless you get a thicker head gasket and adjustable cam gear. it is also possible to skip the cam gear one tooth if you poke a long screwdriver down there to pry the tensioner back, ive done it before.
 
1st off. How else you gonna learn, if you don't make mistakes? :confused:


I bet no one here has got where they are, and not made any mistakes.

No.



How to move a cam sprocket: (also seen in the FSM, which you can (and should) get for free in the FAQ here)




pry bar under the cam sprocket NOT ON THE TEETH, the part that the bolt that holds it, touches


cam (leverage) the pry bar at the point the "hidden bolt" hole or "half moon gasket" is.

Hold pry bar with L or right hand.


Place any type of wrench you want on the crank. As long as you can turn it L & R.


Turn crank in minor increments, both L and Right. As you do it, apply gentle pressure to the pry bar. It will work its way up and slide right over the cam.

It may not go on all the way. More than likely the dowel will be misaligned. No biggie. Just get it on enough you can let it go, and turn the crank until it matches and slip'er right on.



BUT MAKE SURE, the match marks line up. A couple of teeth off and you might bend a valve. One or two and you should be o.k (as far as not bending any valves).

The timing cover (if it's a good one) has little guides that keep the chain from being able to come off the lower sprocket.

Hang in there. Wait till you've put 20 together that just, "fell together" and you get one that just won't go back to save its life.

then you'll really know burnt out :smokin:
