Question about Ford Focus

1 Answer

I have a 1925 vintage Riley sidevalve car engine. How tight/slack should the chain be over the sprockets? There is no tensioner but the dynamo has an eccentric shaft driven by the chain, and the dynamo can be turned in either direction to tighten or slacken the chain. At present I have over 1" play in the chain over the longest run - about 8 inches. Your make and model options below do not include my car, so I have put Ford/Focus in order to process my question. I hope you can advise. Thank you.

Sounds like a bit of logic will accomplish a level of tension that will allow running without permitting the chain to climb the teeth to a point where a skip or jump off chain occurs. Just beyond that tension would seem practical while minimizing wear.
Sounds like a fun car. Maybe you will become the only Riley specialist !

  4. Make sure all of the slack is above the tensioner. Gently pry off timing chain tensioner spring retainer, then remove the spring. NOTE: On the 2.3L engine two styles of tensioners are used. Early production engines will have a spring post and late production ones will not. Both styles are identical in operation and are interchangeable.
  5. Remove the timing chain tensioner shoe retainer.
  6. Make sure all the slack in the timing chain is above the tensioner assembly; remove the chain tensioner shoe. The timing chain must be disengaged from the wear grooves in the tensioner shoe in order to remove the shoe. Slide a suitable small prybar under the timing chain while pulling shoe outward.
  7. If difficulty is encountered while removing chain tensioner shoe, proceed as follows:
    1. Lower the vehicle.
    2. Hold the intake camshaft sprocket with a camshaft sprocket wrench - J 39579 or equivalent holding tool and remove the sprocket bolt and washer.
    3. Remove the washer from the bolt and re-thread the bolt back into the camshaft by hand. The bolt provides a surface to push against.
    4. Remove intake camshaft sprocket using a 3-jaw puller in the 3 relief holes in the sprocket. NOTE: Do NOT try to pry the sprocket off the camshaft or damage to the sprocket or chain housing could occur.
  8. Unfasten the tensioner assembly attaching bolts, then remove the tensioner. CAUTION
    The tensioner piston is spring loaded and could fly out causing personal injury. Use care when removing.
  9. Matchmark the timing chain outer surface for reassembly purposes.
  10. If equipped, remove the chain housing to block stud, which is actually the timing chain tensioner shoe pivot.
  11. Remove the timing chain.
  12. Inspect the parts for wear, then replace if necessary. Some scoring of the timing chain shoe and guides is normal. Clean the old sealant off of the bolt with a wire brush. Clean the threaded hole in the camshaft with a round nylon bristle brush. To install: WARNING
    Failure to following installation procedures can result in severe engine damage.
  13. Install the intake camshaft sprocket onto the camshaft with the marked surface showing. Install the sprocket retaining bolt and washer. Use an adhesive compound 12345493 or equivalent on the bolt. Tighten the bolt to 52 ft. lbs. (70 Nm), while holding the sprocket with tool J-36013, J 39579 or equivalent, if removed.
  14. Install tool J 36800 or equivalent, through hole(s) in the camshaft sprocket(s) into the holes in the timing chain housing. This positions the camshafts for correct timing. Fig. 3: Placing the camshaft sprockets onto the marked surface of the camshaft 91063g30.gif
  15. If the camshafts are out of position and must be rotated more than 1?8 turn in order to install the alignment dowel pins:
    1. The crankshaft must be rotated 90°clockwise off of TDC in order to give the valves adequate clearance to open.
    2. Once the camshafts are in position and the dowels installed, rotate the crankshaft COUNTERCLOCKWISE back to TDC. NOTE: Do NOT rotate the crankshaft clockwise to TDC, or valve and piston damage could occur. WARNING
      The side of the timing chain that was marked must be facing outward when installed.
  16. For DOHC engines only, install the timing chain over the exhaust camshaft sprocket, around the idler sprocket and around the crankshaft sprocket.
  17. Remove the alignment dowel pin from the intake (DOHC only) camshaft. Using dowel pin remover tool J 39579 or equivalent, rotate the intake (DOHC only) camshaft sprocket counterclockwise enough to slide the timing chain over the intake (DOHC only) camshaft sprocket. Release the camshaft sprocket wrench. The length of chain between the two camshaft sprockets will tighten. If properly timed, the intake camshaft alignment dowel pin should slide in easily. If the dowel pin does not fully index, the camshafts are not timed correctly and the procedure must be repeated. Fig. 4: Place the timing chain over the exhaust camshaft and around the idler sprocket and around the crankshaft sprocketDOHC engines 91063g31.gif
  18. Leave the alignment dowel pins installed.
  19. Raise and safely support the vehicle.
  20. With slack removed from chain between intake camshaft sprocket (camshaft sprocket for SOHC engines) and crankshaft sprocket, the timing marks on the crankshaft and the cylinder block should be aligned. If marks are not aligned, move the chain one tooth forward or rearward, remove the slack and recheck the marks.
  21. If equipped, tighten the chain housing to block stud. The stud is installed under the timing chain. Tighten to 19 ft. lbs. (26 Nm).
  22. For vehicles through 1991, reload timing chain tensioner assembly to its "zero'' position as follows:
    1. Assemble restraint cylinder, spring and nylon plug into plunger. Index slot in restraint cylinder with peg in plunger. While rotating the restraint cylinder clockwise, push the restraint cylinder into the plunger until it bottoms. Keep rotating the restraint cylinder clockwise but allow the spring to push it out of the plunger. The pin in the plunger will lock the restraint in the loaded position.
    2. Install tool J-36589 or equivalent, onto plunger assembly.
    3. Install plunger assembly into tensioner body with the long end toward the crankshaft when installed.
  23. For 1992-98 vehicles, reload timing chain tensioner assembly to its "zero'' position as follows:
    1. Form a keeper from a piece of heavy gauge wire. See the accompanying figure.
    2. Apply slight force on the tensioner blade to compress the plunger.
    3. Insert a small prybar into the reset access hole, then pry the racket pawl away from the ratchet teeth while forcing the plunger completely in the hole.
    4. Install the keeper between the access hole and the blade. Fig. 5: View of reloading the timing chain tensioner assembly to its "zero'' position - 1992-98 vehicles 86883177.gif
  24. Install the tensioner assembly to the chain housing. Recheck the plunger assembly installation. It is correctly installed when the long end is toward the crankshaft.
  25. Install and tighten timing chain tensioner bolts. Tighten to 89 inch lbs. (10 Nm).
  26. Install the tensioner shoe and tensioner shoe retainer. Remove the special tool J-36589, then squeeze the plunger assembly into the tensioner body to unload the plunger assembly.
  27. Lower vehicle enough to reach and remove the alignment dowel pins.
  28. Rotate crankshaft clockwise (normal rotation) two full rotations. Align the crankshaft keyway with the mark on the cylinder block, then reinstall the alignment dowel pins. The pins will slide in easily if the engine is timed correctly. WARNING
    If the engine is not correctly timed, severe engine damage could occur.
  29. Install the timing chain guides and, if equipped, the crankshaft oil slinger.
  30. Install the timing chain front cover. For details, please refer to the procedure located in this section.
  31. Connect the negative battery cable, then start the engine and check for oil leaks.

My 1990 nissan sentra has a noisy timing chain when running idle.


Your timing chain tensioner is using oil pressure to stay tight.Could be your oil pressure is so low at idle the tensioner just can't stay tight.At the next oil change you could go for a thicker oil and see if the tensioner keeps the chain tighter at idle.

Timing specs


Here is All Lititure But Pictures Wont show up on FixYa for some reason, I can Email it ALL to you Just Send Me A Request to my Nickname here @aol.com


SPECIAL TOOLS REQUIRED (or equivalents)
  • J-36008, Camshaft sprocket timing alignment pins.
  • J-39579, Camshaft sprocket wrench.
CAUTIONS:
  • The timing chain on the 1996 LD9 (VIN T) Twin Cam Engine is not to be replaced with the timing chain from any other model year. The timing sprockets are different on the Twin Cam Engine and the shape of the links matches the sprockets. Engine damage may result if the wrong timing chain is used.
  • The timing chain and crankshaft sprocket MUST be marked so that they are reinstalled with the same side facing out at the time of reassembly.
  • Failure to follow the removal and installation procedures could result in severe engine damage.
REMOVE OR DISCONNECT
  1. Negative battery cable.
  2. Front cover, refer to Timing Cover / Service and Repair .
  3. Rotate crankshaft in clockwise direction until camshaft and crankshaft timing marks are aligned.
  4. Timing chain guides.
  5. Raise and support vehicle.
  6. Ensure slack in timing chain is above tensioner assembly, then remove chain tensioner. The timing chain must be disengaged from grooves in tensioner shoe to permit removal of shoe. Position a suitable screwdriver under timing chain while pulling shoe outward. If difficulty is encountered in removing tensioner shoe, proceed as follows:
    1. Lower vehicle, then while holding the intake camshaft sprocket with J-39579, remove sprocket bolt and washer.
    2. Remove washer, then install bolt into camshaft by hand.
    3. Position a suitable three jaw puller into intake camshaft sprocket relief holes and remove sprocket. CAUTION: Do NOT pry on camshaft sprocket as damage to sprocket or timing chain housing may result.
  1. Tensioner assembly attaching bolts and tensioner assembly.
  2. MARK CRANKSHAFT SPROCKET AND TIMING CHAIN outer surface for reassembly.
  3. Timing chain.
INSTALL OR CONNECT
  1. Intake camshaft sprocket onto camshaft with surface marked during removal showing.
  2. Intake camshaft sprocket retaining bolt and washer, torque to 70 Nm (52 ft lbs) while holding the sprocket with J-39579 (if removed).
  3. Timing pins, J-36008, through holes in camshaft sprockets into holes in timing chain housing to position camshafts for proper timing. If camshafts are out of position and must be rotated more that 1/8 turn to insert timing pins:
    1. Crankshaft MUST be rotated 90°clockwise off of TDC in order to give the valves adequate clearance to open.
    2. Once the camshafts are in position and the timing pins have been installed rotate crankshaft COUNTERCLOCKWISE to TDC. CAUTION: Do NOT rotate the crankshaft clockwise to TDC, valve or piston damage could occur.
  1. Timing chain over exhaust camshaft sprocket, around idler sprocket and around crankshaft sprocket.
  2. Set camshaft sprockets at timed position and install timing chain. Remove timing pin from intake camshaft. Using J-39579, rotate the intake camshaft sprocket counterclockwise until timing chain can be installed over sprocket. Release J-39579 after timing chain has been installed over sprocket. The length of chain between intake and exhaust camshaft sprockets should tighten. The timing pin should easily fit through intake camshaft sprocket timing hole into timing chain housing timing hole. If timing pin does not fully index, the camshafts are NOT timed correctly and the procedure MUST be repeated.
  3. With timing pins installed, raise and support vehicle.
  4. With slack removed from timing chain between intake camshaft sprocket and crankshaft sprocket, timing marks on crankshaft and engine block should be aligned. If the marks are not aligned, move timing chain one tooth forward or rearward to align marks. Remove slack and recheck marks.
  5. Reload tensioner assembly to zero position as follows:
    1. Form a keeper out of heavy gauge wire into a U-shaped piece with a half inch opening.
    2. Apply slight force on tensioner blade to compress plunger.
    3. Insert small screwdriver into reset access hole and pry rachet pawl away from ratchet teeth while forcing the plunger completely in the hole.
    4. Install keeper between access hole and blade.
  1. Tensioner assembly to chain housing and recheck plunger assembly installation, noting long end is toward crankshaft.
  2. Tighten timing chain tensioner bolts to 10 Nm (89 in lbs) .
  3. Lower vehicle to point where timing pins can be removed from camshaft sprockets.
  4. Rotate crankshaft two revolutions in the clockwise direction. Align crankshaft keyway with the mark on cylinder block and reinstall timing pins through camshaft sprockets into housing timing holes. Timing pins should slide easily through timing holes. If timing pins cannot be inserted easily, repeat procedure to properly time engine. CAUTION: If the engine is not correctly timed, severe engine damage could occur.
  5. Timing chain guides.
  6. Engine front cover.
  7. Negative battery cable.
