Looks like he added it to the post with the "better" pic, edited there. I guess. Hope you get 'er dialed in Darko!

I've never claimed to be perfect here folks,even goofed in this thread here looking at the "new" pic and typed before I really looked closer (post 18),the marks on the crank gear are very hard to see in these pics,even the new pic.
But the visible marks that I can see counter-clockwise are the - marks,so looking at the solo crank gear pic the + mark is the next mark clockwise from those marks,so the + mark (advanced) has to be the mark being used to line this up currently,even though it kinda looks like a "dot" now... But without the context of the other marks and keyways,any comments were just lucky guesses,and really without degreeing to find out for sure,they're still nothing more than guesses,as I have run into more than a few low-cost/budget multi-key crank gears that were mismarked. Dont take anything for granted. |

4 cycle engine,720 degrees of crankshaft rotation to make a full engine cycle,two full rotations of the crank,and one full rotation of the cam. There are four strokes,intake,compression,power,exhaust. TDC/BDC for both the intake and exhaust events. Basic engine theory. For those that are lazy and hate math,use an online calculator like the one at wallace racing: Just click the hotlink camcalc here. Once you determine the intake and exhaust opening and closing points the rest falls into place more or less. It can be done without a timing card,tedious,but possible. Lift is even easier to determine,just measure the lobe lift and mutliply by the rocker ratio and you get the lift at the valve. Or you can pull the cam,then you could determine the maker and the part number likely as that info is often stamped on the rear face of the cam journal. Then you can look up the specs and often find a cam card online. HTH. Bret. |

That's fine, keep digging.
Bret, Nice "edit" you Internet Moron! Why don't you stop living on the computer, reading books, and attempting to be a professional? Try getting a car running then you might get some respect. Just being a long winded "blow-hard" doesn't make you right. You live by the "Baffle them with BS theory and deliver it in tons. You edited your commentNice cover up) "There is NO way to degree a camshaft without multiple key ways". I called BS on you!, your the one who blew up, started crying like the girl you are, and posted the way you did. "News FLASH" your not an expert and probably won't live long enough to ever become one! Keep up the "name calling" little man because sooner or later, "God Willing", we will have the chance to meet in person. Then we will "clarify" exactly where you stand in the "pecking" order. Please feel free to enjoy yourself in the time being!

The gearsets with multiple keyways always confuse the heck out of me. I set them up striaght and degree the cam with offset keys then confirm with a degree wheel and dial indicator on #1 intake lobe.
