I have this 89 acura legend 2.7l v6 timing belt removed and the water pump removed, the old pump failed which caused the belt to fail, i have new parts and the pump installed only i dont understand to...


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).

Timing belt


TIMING BELT & SPROCKETS R & I
NOTE: Some procedures may differ slightly due to engine
construction.
Removal
1) Remove all necessary air ducts. Position No. 4 piston at
TDC of compression stroke. Align timing marks. See Fig. 2. Remove fan
and fan shroud. Remove belts. If necessary, remove radiator and
splashguard.
2) Prevent engine from rotating and remove crankshaft timing
pulley retaining bolt. Remove upper and lower timing belt covers.
Remove spring from tension pulley. Loosen adjusting bolt and move
pulley toward water pump. Remove timing belt.
CAUTION: Ensure pistons are at TDC when rotating camshaft or damage
may result.
Inspection
1) Handle timing belt carefully. Avoid twisting or kinking
belt. Do not allow belt to become contaminated by water, oil, dirt or
other contaminates. Inspect belt for cracks or damage. If necessary,
replace.
2) Measure tension pulley spring length and force. Spring
length should not exceed 2.76" (70.2 mm) and spring force should not
be less than 197-347 lbs. (27-48 kg).
3) Replace tension pulley spring if not within specification.
Installation
1) Pull tensioner fully toward water pump side and
temporarily tighten retaining bolt. Ensure No. 4 cylinder is at TDC on
compression stroke by rotating crankshaft until keyway aligns with
mark on front crankshaft seal housing (12 o'clock). Rotate camshaft
until timing mark on cam gear (arrow) aligns with mark on upper
camshaft cover (notch). See Fig. 2.
NOTE: When timing marks are aligned as stated above, No. 4 piston
is at TDC on compression stroke.
2) Position timing belt over crankshaft sprocket, oil pump
sprocket, camshaft sprocket and tensioner in that order. Ensure belt
is positioned in sequence given and without slack between sprockets.
Loosen tension sprocket adjusting bolt allowing spring tension to
tighten belt. Tighten adjusting bolt temporarily.
3) Temporarily install crankshaft pulley bolt and rotate
crankshaft 2 complete revolutions in opposite direction of engine
rotation, until marks on crankshaft and front oil seal retainer are
aligned again. See Fig. 2. Loosen tensioner lock bolt, allowing
tesioner spring to fully adjust tension. Tighten tensioner lock bolt.
4) Install timing belt covers. To complete installation,
reverse removal procedures. Tighten all bolts to specification. See
TORQUE SPECIFICATIONS table at end of this article.

I am planning to replace the timing belt on my daughter's 95 Corolla and was wondering what I need to align where before removing the belt eg How do I find TDC? Camshaft pulley and Crankshaft pulley...


TDC is top dead center/ remove spark plug on cylinder no. 1/ rotate the crankshaft pulley using a socket wrench and power handle and check if the piston on your cylinder no. 1 reach the top center that is TDC/ remove timing belt cover and locate a synchronized marking on your camshaft and crankshaft pulley/ remove old timing belt/ install a new one but make sure that the mark on your camshaft and crankshaft is perfectly synchronized before putting the cover/ manually rotate the crankshaft pulley again and see if it rotates 360 deg. freely then you can be sure you did the job correctly.

How to set timming belt,cant find mark for crankshaft 3.0L


Timing belt removed, static timing was not set before removing timing belt.

[Set Static Timing:
No.1 piston is brought up to TDC before removing timing belt.

Cam gear has a punchmark on face of gear, and this mark aligns with one single tooth. There is a matching punchmark on the Timing Belt Rear Upper Cover.

Facing the cam gear, the mark is to the upper right. There is an 'egg shape' of the timing belt upper rear cover, in this spot. This punchmark is in that 'egg shape', and is close to a bolt hole. The cam gear mark lines up with the Timing Belt Rear Upper Cover, mark.

The crankshaft gear has a punchmark on the face. It lines up with one single tooth. There is a corresponding punchmark on the lower right side. An alignment mark)

Should be a round punchmark on the face of the crankshaft gear. It lines up with a single tooth. Wipe the gear clean, use a little carb cleaner. (NO flames, or sparks nearby, well ventilated area)

Barring you cannot find the crankshaft mark, find the camshaft alignment marks, make sure they are aligned with the alignment, (Punchmark), on the Timing Upper Rear Cover.

Count the teeth in the timing belt. There should be 133 teeth on the belt.

There is 43 teeth in-between the timing mark of the camshaft, and the timing mark on the crankshaft.

(43 teeth in-between the Right Side Camshaft mark to crankshaft mark, 43 teeth in-between the Left Side Camshaft mark to crankshaft mark)

There should be 40 teeth in-between the two cam gears.

Camshaft timing mark crankshaft timing mark


Belt covers need to be on. Timing mark on crankshaft (while on compression stroke) should line up with TDC mark on cover. then Camshaft mark, needs to line up by looking through access hole of cover, and align mark on cam sprocket with pointer on inside of belt cover.
