Guest ZmeFly Posted December 31, 2003 Share Posted December 31, 2003 Ok I think this is simple enough but just to clarify and or see if my thinking is wrong or not. If say I wanted to move the cam position from position 2 to position one, would I make sure the engine is at TDC compression stroke, and then remove the cam sproket and turn the cam to the desired position or?? Thanks for any help James Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted December 31, 2003 Share Posted December 31, 2003 No. You bring the balancer up to TDC, after breaking loose the nut on the front of the cam. Then you stake the timing chain in place, and remove the sprocket, and rotate it until the hole you want lines up with the dowel on the cam. Then put the nut back in, tighten to spec, and remove the timing chain stake. It helps to make sure your balancer is on at TDC to, which you can also verify by removing the spark plug and looking in the hole and making sure the piston is at TDC. Also the front two cam lobes should be in the up but spread apart position. Kind a like a peace sign. good luck. I always liked the number 2 position.

JMortensen Posted December 31, 2003 Share Posted December 31, 2003 Just a tip to make life easier (something you may already know): get a long 10mm wrench and loosen the top of the curved chain guide and push it back so that you have a little more slack on the chain. Otherwise getting the cam gear back on is a PITA. Jon Quote Link to comment Share on other sites More sharing options...
TimZ Posted January 1, 2004 Share Posted January 1, 2004 No. You bring the balancer up to TDC, after breaking loose the nut on the front of the cam. Then you stake the timing chain in place, and remove the sprocket, and rotate it until the hole you want lines up with the dowel on the cam. Then put the nut back in, tighten to spec, and remove the timing chain stake. You also need to make absolutely sure that the chain link that was on the sprocket tooth marked #1 is now on the sprocket tooth marked #2. The timing chain usually has two links on it that are brighter than the rest (silver instead of black) - these are for aligning the crank and cam properly on installation. I usually rotate the engine by hand until one of the bright links come up on the #1 tooth before I pull the sprocket - it's much easier to get it right this way.

Jon Well, I did that once and the slight movement of the chain guide apparently loosened the bottom chain guide screw ever so slightly and it ended up coming all the way out so I would suggest only doing that as a last resort.
