Align it with the dot on the crank gear.
the cam gear and the crank gear are dot to dot
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.
abuse, not keep your car maintained. it can blow an engine. If the belt was replaced and then began shredding, the shim washer on the crank may have been installed between the lower crank gear and the block. The shim washer should be between the the crank gear and the crank pulley.
there should be a dot or line cut in each gear. the cam gear mark should be at the six o'clock position (all the way down) and the crank mark at the 12 o'clock(all the way up). line them up and you should have it made. spin the crank just to be sure the marks mesh correctly
check your crank gear it is worn out replace the gear and key
The cam gear is on top/ and the crank gear is on top. Both at 12:00.
You do it when you're building the engine. You can do it without any visual aids, but it's easiest to do this if you buy a bottle of model paint. The cam timing system on an aircooled VW engine has a fairly small gear on the crankshaft, and a large one on the camshaft. The gear on the cam has a dot ground into one tooth; the gear on the crank has a dot on two adjacent teeth. You paint the teeth to make it easier to pick them out because those dots aren't very large at all. But whether you do or not, lay a case half on the table with the side the crank goes in facing up and install the crank and cam bearing shells in the case. Set the crank into them, and rotate it until you can see the two teeth on the crank gear. Mesh the cam gear with the crank gear so the dot on the cam gear is between the two dots on the crank gear. Roll the cam down into its bearings. (You DID put some assembly lube on them, right?) Now rotate the crank a few revolutions while watching the gears. If the dotted tooth on the cam gear always winds up right between the dotted teeth on the crank gear, you've done it right.
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
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.
It has a chain with a cam gear and crank gear.
A round piece of pipe, that fits over the crank snout, and a big hammer.
