Where is the TDC on a Nissan Xterra?
Using the bolt on the end of the crank and a ratchet rotate the crank while keeping a hand on the screwdriver and by rocking the crank back and forth you will feel when the screwdriver is at it’s highest point, this will be TDC for No. 1 cylinder.
How to set TDC on Xterra harmonic balancer?
1. Confirm that No. 1 piston is set at TDC on its compression stroke. 2. Install tensioner and tensioner spring. Once stud is removed, apply locking sealant to threads of stud on cylinder block side before installing. 3. Turn tensioner fully outward with hexagon wrench, and temporarily tighten lock nut. 4. Set timing belt when engine is cold. a.
Which is the 4th mark on harmonic balancer?
On the 4 cyl model, the 4th mark is 5 degrees retarded, and my Nissan runs like a vehicle that needs more timing, and I am wondering if I got the cams synced ok, but the crank is 5 degrees retarded?
How to set No 1 piston at TDC in XTERRA?
Loosen tensioner lock nut, then turn tensioner clockwise and counterclockwise with hexagon wrench at least 2 times. 2. Tighten tensioner lock nut. 3. Turn crankshaft clockwise at least 2 times, then slowly set No. 1 piston at TDC on its compression stroke.

How do I know when TDC?
Mark your balancer with a marker, and then slowly rotate the crankshaft by hand in the opposite direction; until you come up against the stop again. Mark your balancer again. Measure the distance between the two marks and divide by two. As a result, This is your (TDC).
How do I know if my diesel is at TDC?
To find the Top Dead Center (TDC) on a diesel engine, virtually all diesels will have a mark on the front pulley and another mark cast into the front housing, just line the two up.
How do you find the top dead center of an engine?
Step 5: Verify that the engine is in top dead center position. Once the top dead center timing mark is lined up with the marker on the engine, the motor should now be at top dead center. To verify, shine the flashlight down into the spark plug hole. You should be able to see the top of the piston clearly near the top of the cylinder.
Where are the timing marks on an overhead cam engine?
Once the valve cover is removed, you should be able to see the camshaft, or camshafts, if it is a dual overhead cam engine. Look for the camshaft timing marks located on the gears. They are usually clearly marked in the form of notches, pins or sometimes stamped words.
Where are the timing marks on a crankshaft?
Look for the camshaft timing marks located on the gears. They are usually clearly marked in the form of notches, pins or sometimes stamped words. Note: If you are unable to identify your timing marks, refer to a service manual for guidance to ensure that the engine is set to proper top dead center. Step 5: Turn the crankshaft pulley.
