    when setting your timing belt.,the cam sprocket points straight up, but two different books say different things on the crank pulley,ONE SAYS put mark at ten degrees before tdc the other says at tdc, which is right

I think u might be mis-understanding. 10 degrees BTDC deals with Ignition timing. When setting the timing belt, set it at TDC

Removing/ Install the timing belt cover 95 geo metro 1.3


First did the belt break? You have an interference engine. If it broke while a stop. It maybe OK. If at highway speeds, it is trashed. This has to be checked out first. Remove the cams and do a leak down test on the cylinders. Interference engines will bend/break valves and punch holes in the pistons. If any of this happened, the car is not worth fixing. A replacement engine will cost more than it is worth.

1995 2.3L 4W ISUZU RODEO HOW DO YOU GET IT BACK IN TIME


Remove timing belt cover and the timing belt. Line up the cam gear timing mark with the mark that is behind it. Then, set the crankshaft pulley timing mark to zero degrees or whatever the book says. Then re-install the timing belt and re-torque the timing belt tensioner to the proper torque. Turn the engine one full turn, with a breaker bar and socket. Re-check the timing marks on the crankshaft and camshaft. Re-install the timing belt cover and everything else you took off to get to the belt. Be sure to torque the crankshaft pulley bolt to specs.

How to set timing chain on a 1997 audi a4 1.8 non turbo


SET?
is this a ground zero, never looked question
our 1.8 has a belt and chain.
called the AEB engine. 20 valves.... or is it the 16valve>?

1.8 R4 20vT

ours is the DOHC head,
there are 47 steps. in the FSM.
and photos , (log in to alldata.com and look?)

the engine as s chain at the rear of the 2 cams, linking them.
and a front drive belt all must be timed by the book.
the first, fact to discover, is if it is and INTERFERENCE engine.
Im told it IS>!
if yes, do not crank engine over, util you are 3 times sure of timing
or boom, kiss off valves, or more..... damage has no limits.
the book tells you to match mark, the rear chain sprockets.
ill skip this, you implied front of engine belt.
there are 2 chapters one for rear chain
and one for belt.
here is the belt side.

quote. removal.
  1. Note the radio security code and disconnect the negative battery cable.
  2. Place the (hood) lock carrier in the service position. For additional information, please refer to the following topic(s): Body And Trim, Service Position, Front Bumper, Hood Lock Carrier.
  3. Remove the engine accessory drive belts. For additional information, please refer to the following topic(s): General Information And Maintenance, Routing Maintenance And Tune-up.
  4. Using a 5 x 60mm bolt, secure the viscous fan pulley. Using a hex wrench, remove the viscous fan-to-pulley bolts. Remove the viscous fan assembly.
  5. Turn the engine by hand to Top Dead Center (TDC) on the firing stroke for cylinder No. 1.
  6. Remove the upper timing belt cover.
usually a dumb idea this.... but is stated.
If reusing the timing belt, mark its rotational direction so it may be installed in its original position.
  1. Using the center bolt, rotate the crankshaft in the direction of engine rotation to position the No. 1 cylinder at Top Dead Center (TDC) of its compression stroke.
  2. Remove the damper pulley-to-crankshaft bolts and the damper.
  3. Remove the lower timing belt cover.
  4. Using a Torx Wrench T45, or equivalent, loosen the timing belt tensioner, push the tensioner downward and remove the timing belt.

SEE 5 MISSING PHOTOS THEN,.
iNSTALL
  1. Align the camshaft sprocket timing mark with the cylinder head cover mark.
  2. Install the timing belt on the crankshaft sprocket with the arrow facing the rotational direction.
  3. Install the lower timing belt cover.
  4. Using a bolt, secure the damper/belt pulley on the crankshaft.
  5. Align the crankshaft damper/belt pulley with the housing timing mark so that the No. 1 cylinder is at TDC of its compression stroke.
  6. Install the timing belt on the camshaft sprocket and belt tensioner.
  7. Using a 2-pin Spanner Matra Tool No. V159 Wrench, or equivalent, lift (turn clockwise) the timing belt tensioner cylinder No. 1 until it is fully extended and tensioner cylinder No. 2 is raised approx. 1mm (3/8 inch); then, hand-tighten the mounting bolt.
  8. Rotate the crankshaft 2 complete rotation in the running direction.
  9. Inspect area 'A' for proper alignment with the upper edge of piston No. 2 and adjust if necessary.
  10. Area 'A' - adjustment OK
  11. Area 'B' - wear limit
  12. Area 'C' - re-adjust and check belt drive including tensioner for wear.
details, (devil?)
If the piston edge is located in area 'A', measurement 'D' is 25-29mm (31/32-1 1/8 inches).
  1. After adjustment has been verified, secure the tensioner with a 2-pin Spanner Matra Tool No. V159 Wrench, or equivalent, and tighten the mounting bolt.
  2. Complete the damper to crankshaft installation.
  3. Using the center bolt, rotate the crankshaft 2 rotations in the direction of engine rotation until the camshaft and crankshaft marks align with their respective reference points.
  4. Install the upper timing belt cover.
  5. Install the drive belts.
  6. The balance of assembly is in reverse order of removal.
  7. Install the negative battery cable last.
  8. Test drive the vehicle.

login to alldata.com and just look, its $15 bucks.
the cost is about 1/10 of 1hour shop labor charges, stateside,
free IMO..
PS : a savvy mech will not do step 8 ,until he:
1: spins engine over by hands sparks out, to feel if the valves hit the pistons, ( a DUH factor if ever. there was)
and TRIPLE checking. all timing marks again before close up.

there is no forgiveness, like on free runners. not at all.

Hi, here is what you need to do. Get all of the timing marks lined up as indicated in the picture below. Put the belt on. Without moving the gears off their marks, make the belt tight across the cam gears and then down the right side to the crank gear. All of the slack must be on the left side to be taken up by the tensioner. Release the tensioner to tighten the belt and then verify the marks are still aligned. If the marks are not aligned, loosen the tensioner just enough to turn the gear that needs to be realigned. After tensioning the belt, rotate the crankshaft clockwise 720 degrees and recheck the timing marks. I have pasted the book procedure below. Please let me know if you still have questions. You must get this right.

  1. If the crankshaft or camshafts have been turned with the timing belt removed, remove the spark plugs and advance the crankshaft about 15 degrees beyond TDC of No. 1 cylinder. Make sure the camshaft sprockets are properly aligned with the marks and return the crankshaft to the TDC mark.
  2. Install the belt in sequence on the crankshaft, the front camshaft, water pump and tensioner pulleys, then the rear camshaft.
  3. To adjust the tension, loosen the tensioner pulley bolt about 1 / 2 turn. The spring will automatically set the proper tension. Torque the bolt to 31 ft. lbs. (43 Nm).
  4. Rotate the crankshaft 6 turns clockwise and check that the timing marks on the crankshaft and camshafts align properly. Adjust the timing belt tension again by rotating the crankshaft to the align the blue mark on the pulley with the pointer. Loosen and retorque the tensioner pulley bolt.
  5. Install the remaining parts in reverse order. Torque the crankshaft pulley bolt to 83 ft. lbs. (115 Nm). When installing the side mount bracket, torque the bolts to 40 ft. lbs. (55 Nm).
