How can I remove gear-to-gear timing cam? - 1998 Chevrolet S-10 Pickup

Replacing the chain and gears requires removing the water pump, dropping the oil pan, removing the balancer and timing cover. Rotate the crank so the dots on the cam gear and crank gear line up at the 6 and 12 o clock positions respectively. Unbolt the cam gear and remove it and the chain. If you need to remove the crank gear you can use a three jaw puller or something similar to pull it off. Reinstall the crank gear lining up the gear with the keyway on the crank and press it on with the appropriate tool. Install the cam gear with the chain and make sure dots line up again. It may be necessary to remove the valve covers and rocker arms as well to rotate the cam shaft if need be.

22R 4 cyl.Get # 1 piston to TDC(stick the harmonic balancer back on temporary)setting the mark to O on the timing tab,pull the balancer back off and slip the chain on the crank gear after finding the single dot on the chain.Set the mark on the cam gear at very top and put the chain mark on that mark on the cam gear.Stick the cam gear back on the cam and bolt it back on.Your set now.

Without writing a book, jack up the car and remove the passanger side tire...best access via the wheel opening...you must remove the harmonic balancer, water pump and timing cover to replace the timing gear. Unless you have lots of miles they go a long time.
The cam magnet is behind the cam sensor, remove it and manually rotate the engine until the hole in the cam is visible. You might find the old magnet. Clean out the hole, glue in the plastic holder and magnet.

Same as any other v-8 dis-assemble the front of the engine to get to the timing cover. Loosen the oil pan bolts to allow the timing cover to be slipped out. unbolt and remove the timing cover. Turn the engine over by hand until the dot on the crankshaft gear( the small one) is at the top 12 oclock position, and the dot on the cam gear(large gear) is at the bottom 6 oclock position remove the old cam gear and old chain. Install new gear and chain with the marks in the same places. Re assemble engine. DO NOT be tempted to just put in a new chain, replace the chain and cam gear as a set, wear on the cam gear will cause the chain to be slack, which in turn causes the cam timing to be late.

That motor has a timing chain, not a timing belt. Replacing it requires removing the water pump, dropping the oil pan, removing the balancer and timing cover. Rotate the crank so the dots on the cam gear and crank gear line up at the 6 and 12 o clock positions respectively. Unbolt the cam gear and remove it and the chain. If you need to remove the crank gear you can use a three jaw puller or something similar to pull it off. Reinstall the crank gear lining up the gear with the keyway on the crank and press it on with the appropriate tool. Install the cam gear with the chain and make sure dots line up again. It may be necessary to remove the valve covers and rocker arms as well to rotate the cam shaft if need be.

To change the timing belt first place the right side of the vehicle on a jack stand and remove the right front tire. Remove the plastic cover inside the wheel well to expose the harmonic balancer. Remove the serpentine belt (standard 3/8" rachet will set in the belt tensioner to relieve tension). Remove the harmonic balancer (19mm). Place a jack under the engine on the right side of the vehicle, then remove the engine mount from the top of the fender well, (17mm deep well socket and 17mm wrench required) it is not necessary to remove the mount from the side of the engine. Remove the timing cover, (10mm) it has 2 nuts. Loosen the timing belt tensioner, (10mm) then pry it away to relieve the tension. Slide the timing belt off of the cam gear.

To position the new belt, the cam gear has a arrow on it, and the cylinder head has a small dot. Align the arrow with dot, and make sure it is aligned (the arrow must point up). The crank gear has a notch and the engine has a groove to align the notch. Again, make sure the notch and groove are aligned (they again will be up). Place the new timing belt in position around the crank gear, the water pump and belt tensioner and leave the slack at the top. Again relieve any tension from the belt tensioner, and slide the belt on to the cam gear. Place a slight bit of tension on the belt and tighten the belt tensioner. Use the 19mm bolt from the harmonic balancer and turn the engine 2 complete turns and verify that the cam gear and crank gear are in their proper positions and aligned with the dots and notches. After 2 complete turns of the engine, and verifying everything is still aligned, re-assemble in reverse. No further adjustment is necessary.

Note:There is no timing adjustment for this vehicle, and if you are not properly aligned on the cam gear and crank gear it will not run properly.

if this is 6VD1 engine it has single cam gear each head, but is still a 2 cams per head, engine
if belt has broke or you have turned any gear you must remove rocker covers to check positions of camshafts front lobes are in certain spot as well as timming mark on belt driven cam gear to cover
this cam gear is a 3:1 ratio (3 turns of cam gear = 1 turn of cams)

There is no timing adjustment "at all" for a 1999 escort. If your timing is out, your timing belt has slipped and needs to be replaced.

To change the timing belt first disconnect your negative battery cable, then place the right side of the vehicle on a jack stand and remove the right front tire. Remove the plastic cover inside the wheel well to expose the harmonic balancer. Remove the serpentine belt (standard 3/8" rachet will set in the belt tensioner to relieve tension). Remove the harmonic balancer (19mm). Place a jack under the engine on the right side of the vehicle, then remove the engine mount from the top of the fender well, (17mm deep well socket and 17mm wrench required) it is not necessary to remove the mount from the side of the engine. Remove the timing cover, (10mm) it has 6 bolts and nuts. Loosen the timing belt tensioner, (10mm) then use a 3/8" rachet in the belt tensioner to relieve the tension. While relieving the tension slide the timing belt off of the cam gear.

To position the new belt, the cam gear has a arrow on it, and the cylinder head has a small dot. Align the arrow with dot, and make sure it is aligned (the arrow must point up). The crank gear has a notch and the engine has a groove to align the notch. Again, make sure the notch and groove are aligned (they again will be up). Place the new timing belt in position around the crank gear, the water pump and belt tensioner and leave the slack at the top.

get number 1 cylinder all the way up then line up the timing marks on the gears with the marks on the housing

In order to replace the cam gear, you have to take it to a machine shop and have it pressed on and off.
