I am removing the intake cam to test and replace the VVTi Timing Gears. It is necessary to place a service bolt in the Exhaust Camshaft Gear to keep it from moving. This went fine on the front since the service bolt was right on top. The rear shaft places the service bolt hole on the bottom and inaccessible. Can I just turn the shaft to get at the service bolt location and turn it back to return timing to * to * markings or will this cause damage? It was placed at top dead center prior to starting this repair and both shafts show matching * to * timing marks.
Hi there:I dont have this diagram for 2S-ELC, 3S-FE and 5S-FE Engines, but pay attention at this... To install:
Align the cutouts of the oil pump pulley and shaft, and slide the pulley on. Retain the pulley while tightening the nut to 21 ft. lbs. (28 Nm).
Align the crankshaft timing pulley set key with the key groove of the crankshaft pulley, then slide the pulley on.
Install the No. 2 idler pulley with the bolt and tighten to 31 ft. lbs. (42 Nm). Be sure the pulley moves smoothly.
Remove any oil or water on the idler pulley and keep it clean.
Temporarily install the No. 1 idler pulley with the retaining bolt. Hint: use a 1.65 inch (42mm) bolt in length. Do not tighten the bolt yet. Install the tension spring. Pry the pulley toward the left as far as it will go, then tighten the bolt.
Turn the crankshaft until the key groove in the crankshaft timing pulley is facing upward. Install the timing belt on the crankshaft timing, oil pump, No. 2 idler and water pump pulleys.
If the old timing belt is being reinstalled, make sure the directional arrow is facing in the original direction and that the belt and crankshaft gear matchmarks are properly aligned.
Install the lower (No. 1) timing belt cover and new gasket with the four bolts.
Align the crankshaft pulley set key with the pulley key groove. Install the pulley. Tighten the pulley bolt to 80 ft. lbs. (108 Nm).
On 2S-ELC engines, turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
Align the camshaft knock pin with the matchmarks on the oil seal retainer.
On 2S-ELC/USA engines, align the knock pin with the pin hole on the timing pulley E mark side. On 2S-ELC/Canadian engines, align the knock pin with the pin hole on the timing pulley. On 3S-FE and 5S-FE engines, align the knock pin with the groove of the pulley, and slide the pulley onto the camshaft with the plate washer and set bolt.
On 2S-ELC engines, make sure that the Matchmark on the oil seal retainer and center hole of the small hole on the camshaft timing pulley are aligned.
Using the removal tool to hold the pulley stationary, install and tighten the pulley set bolt to 40 ft. lbs. (54 Nm) on the 2S-ELC and the 3S-FE. On the 5S-FE, tighten the set bolt to 27 ft. lbs. (37 Nm).
On 3S-FE and 5S-FE engines, turn the crankshaft pulley and align the 0 mark on the lower (No. 1) timing belt cover.
Install the timing belt and check the valve timing as follows:
Align the matchmarks that you made previously, and install the timing belt onto the camshaft pulley.
Loosen the No. 1 idler pulley set bolt 1 / 2 turn.
Turn the crankshaft pulley two complete revolutions TDC to TDC. ALWAYS turn the crankshaft CLOCKWISE. Check that the pulleys are still in alignment with the timing marks.
Tighten the No. 1 idler pulley set bolt to 31 ft. lbs. (42 Nm).
Make sure there is belt tension between the crankshaft and camshaft timing pulleys.
Install the upper (No. 2) timing cover with a new gasket(s). On the 5S-FE, align the two clamps for the engine wiring harness with the cover mounting bolts.
Install the spark plugs.
Install the right mounting insulator with bracket. Tighten the bracket bolts to 38 ft. lbs. (52 Nm), insulator nuts to 38 ft. lbs. (52 Nm) and thru-bolt to 52 ft. lbs. (71 Nm). On the 5S-FE, install the No. 2 engine mount bracket and tighten to 38 ft. lbs. (52 Nm); install the control rod and tighten the bolts to 47 ft. lbs. (64 Nm).
Lower the engine.
On 3S-FE and 5S-FE engines, install the alternator and alternator bracket. On 2S-ELC engines, install the power steering reservoir tank.
Install the drive belt and adjust the tension.

It's a BIG job. It requires removing everything from the top of the engine (intake manifold, throttle body, all plumbing, valve covers) then removing the harmonic damper, most of the accessories, and then the timing cover. That's just to get to the timing chain. You have to remove the chain guides and tensioner, then cam gears and crank gear. If you're going this route, also replace the two chains (intake cam to exhaust cam) on top of the heads, the water pump, and the tensioners. Be very precise in reinstalling the three timing chains so that everything is in time.
The link shows the details of the chain itself, but be aware that your engine is packed into your Intrepid with limited work space in some areas. Chrysler Sebring Concorde 300 2 7L timing replacement Cloyes kit 9 0397SA
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.

During most engine rebuilds, a completely new timing assembly should
be installed. If wear exists on any component, replacement of the entire
assembly is necessary. Wear in the chain, gears, or sprockets means a
timing lag, which results in poor engine performance.
The timing chain or belt is generally installed with the gears in
their correct positions. Before installing a new chain, soak it in oil. OHC (Overhead Cam) Engines
Some OHC engines use a chain drive; others use a belt drive. Removing
the cover on some OHC engines that have timing chains is more
difficult, because the cover often fits between the oil pan and the
cylinder head. There are special procedures for replacing cam timing
components in these engines.
Before a chain repair job, perform a leakage test on non-freewheeling
engines to check for bent valves, so that an accurate repair estimate
can be made. OHV (Overhead Valve) Pushrod Engines
On many OHV pushrod engines, the crankshaft sprocket is installed on
the crankshaft nose and the crankshaft is rotated to position piston #1
at TDC. At this point, a mark stamped onto the crankshaft sprocket is
pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used
to rotate the cam until a mark stamped on the cam sprocket is pointing
directly downward (toward the crankshaft). The sprocket is then removed
from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam
gear is positioned directly downward, and the chain is looped around the
crankshaft sprocket. When the cam sprocket is attached to the cam, the
timing marks on the crank and cam sprockets should be pointing toward
one another. NOTE THIS IS FOR 2WD 4.0
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. Again use a 3/8" ratchet to 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 position 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.
