What happens if the timing belt is off on a Toyota Tundra?
Say if I were to work on my 2000 V8 Tundra and the timing belt is OFF and the cam marks are mixed up and the crankshaft mark is unknown and not lined up.
When is the topdeadcenter position on a Toyota Tundra?
TopDeadCenter “position” is reached on each turn of the crankshaft – however the TDC for engine timing purposes is only reached every other crankshaft rotation. (Four-cycle engine). TDC occurs at the end of the compression stroke of a piston when it has reached the top of the cylinder bore and is ready for the spark plug to fire.
What kind of ignition system does a Toyota Tundra use?
The Toyota V8 uses an “DISTRIBUTORLESS” ignition system, so…… gone are the “old days” of needing to determine if the engine is on the intake or exhaust stroke prior to “droppin in the distributor”. The ECM handles all the ignition timing chores. Awwww!!!!! I see said the blind man!
When does TDC occur in a Toyota Tundra?
TDC occurs at the end of the compression stroke of a piston when it has reached the top of the cylinder bore and is ready for the spark plug to fire. For the purpose of setting the timing between the camshafts and crankshaft (SetEngineTiming) yes, you would need to know whether the crank was on exhaust or compression stroke.
How to line up timing marks, no belt on?
Very good writeup, but just one clarification. On #6, rotate the engine and check the crank and cam pully marks for correct alignment. The belt marks will take many revolutions to all line up exactly as you installed the belt. A couple of rotations is all that is required to know you have it right.
Do you need to know the timing between camshafts and crankshaft?
For the purpose of setting the timing between the camshafts and crankshaft (SetEngineTiming) yes, you would need to know whether the crank was on exhaust or compression stroke. Click to expand…
