if the engine is removed from vehicle you need to remove the intake, the valve covers, the rocker arms, pushrods, and lifters; then you remove the timing cover, then line up the marks on the sprockets by turning the engine over by hand, then remove the cam and crank sprockets and timing chain; then pull out the cam and install the new one; line up the marks on the sprockets and reinstall them turning the cam if necessary; reverse the rest of the procedure.

How do you install a new timing belt and gears in a 1997 Dodge Neon?

Why would you have to install new gears? They are actually cogged sprockets. It depends if you have a single overhead cam or dual overhead cam engine. All assecory belts need to be removed and front right engine mount. Remove crankshaft pulley with applicable puller. Remove timing cover. Loosen timing belt tensioner. Align all cam and crank marks install belt and tighten and re assemble. Not a job you want to do under a shade tree!


How do you reset the cam timing and ignition timing on a 305 small block?

Cam timing you line up the dots on your crank and cam gears. Ignition, put #1 at TDC on compression stoke. With cap off distributor, turn rotor so it points towards #1 cylinder. Do not drop dist onto the oil pump slot. Turn the crank counter clockwise 1 full revolution until your distributor falls down on the oil pump. Then it should fire when you re-install the cap. Adjust timing accordingly with a timing light.
