little cyrcle on cam gear, and a little cyrcle on crank gear. Cam cyrcle should be down and crank cyrcle should be up. They should line straight up and down?
There are two timing marks on a 350 chev one for the cam shaft gear and one for the crank gear. The timing mark on the crank or the on on the bottom of the motor should be facing straight up and the cam shaft gear should be facing straight down this will put you lined up and top dead center.
Put the crank shaft at TDC. There is a dot on one of the crank gear teeth. It should be pointing toward the cam gear. Put the cam gear on without the chain. Turn the cam until the hole in the cam gear is pointing toward the crank. In other words, the hole in the cam gear and the dot on the crank gear should be in line. Then simply remove cam gear and apply the chain. The computer does the fine timing. Nothing to adjust.
The timing marks for the cam sprocket on a 98 S10 is on the front. The marks for the crank shaft is on the oil pump gear.
on the cam gear the mark should be at 6:00 or in other words the mark will be at the bottom of the gear when installed, on the crank gear the mark should be at 12:00 or at the top of the gear when installed, both marks will line up with each other.
The crank gear dot is at 12 oclock when #1 piston is at TDC, Top dead center. Cam gear dot is at 6 oclock. Both dots should be in a stright line over top of each other.
Get a new timing set (crank gear, cam gear, chain) Install crank gear and turn crank so mark on gear is straight up. Loosely install cam gear, turn so mark on gear is straight down. Remove distributor cap, verify rotor is pointing at #1 plug wire. #1 is drivers side front cylinder. If rotor is 180 degrees out (pointing at #6 wire rather than #1) turn crank one full turn clockwise to bring rotor to #1. Marks on both gears should now be directly adjacent to each other, Crank mark up, cam mark down. Gently remove cam gear so as not to rotate cam. Install chain around crank and cam gear, being sure to maintain mark orientation. Bolt cam gear back in place. Check alignment of timing marks, if they are not right remove cam gear and try again. Torque to spec. Your engine is now at TDC #1 on compression stroke. Should fire right up.
the cam should be at 6:00 and the crank at 12:00
one is on the cam gear and the other is on the crank timing belt gear. spark timing is on the crank to the rear of the engine
Crank gear dot should point stright up / 12o clock with #1 pistion at TDC.all the way up at the top of #1 cylinder.The cam gear dot should point stright down At 6o clock. That will make both dots stright over top of each other. Then the crank and cam will be in time.
The crank gear should be in the 12: oclock position & the cam gear should be in the 6: oclock position facing each other this is top dead center on compression stroke.
on the balencer there is a timing mark and om the motor theres a tab there is also a mark on the cam gear, when lined up, both marks on the crank gear and cam gear point up.
The crank gear dot should be at 12 o'clock stright up when #1 pistion is all the way to the top of the cylinder. The cam gear dot should be at 6 o'clock stright over top of the crank gear dot. Then put it back together.
For the crank shaft, there is a mark on the oil pump gear which should be straight up, same as the key way if you want to go by that. On the cam the pulley has a mark that should be pointing straight up toward the "V" in the cover behind the pulley. Hope this helps.
NO... The crank gear is at 12oclock with #1 piston at TDC Top dead center means The piston is all the way up in the cylinder on the compression stroke. The cam gear dot should be at 6oclock in a stright line over top of the crank gear dot. STRIGHT OVER TOP OF EACH OTHER.
The dot on crank gear should be stright up at 12oclock. Cam gear dot stright down at 6 oclock. Both dots should be stright over top of each other.
the cam gear mark is set at 6 o' clock and the crank gear mark is set at 12 o'clock.
ignition timing marks are on front cover above crank pully. Timing belt marks, above crank gear at 2 o'clock position there is a notch, and top cam gear has hole which lines up with hole in cover with 1\8 drill bit.
The cam gear is on top/ and the crank gear is on top. Both at 12:00.
I thought that timing was measured off the crank gear and the cam gear. Not the flywheel :P
First set the crank shaft gear inline with its pointer or timing mark and do the same with the oil pump, as for the cam gear set up there are two marks. These two marks of indent on the cam gear are to basically be lined up with the brim of the cylinder head. There should be one on the left side and one on the rite side and in between these two marks the word "UP" which is on the cam gear shud be pointin up while the two makrs are dead even with the brim or top of the head. make sure the arms are adjusted on the cam as well
It has a chain with a cam gear and crank gear.
Align it with the dot on the crank gear.
the cam gear slot is set at 6:00 and the crank gear slot is at 12:00.
there should be little dots on the crank and cam gears.... just line them up when you put the cam and the timing chain on and you should be good. the cam gear you cant screw up because it has a dowel the goes into the cam gear and the crank is keyed so it gets pressed on the right spot... very easy
