Why is the timing belt locked in place?
Timing belt was locked into place due to jumping off alignment and chewing into plastic timing belt cover. As a result the crankshaft has been rotated independently of the camshafts. I am now attempting to realign them before installing the new belt, with no belt on mind you.
How do you find the dead center on an engine?
Usually it can be found by looking at timing marks; but on some engines these marks may be lost or hidden. Fortunately there’s an easy way to discover top dead center without the use of any timing marks. So, Being able to accurately find Top Dead Center (TDC) is a critical step; no matter what engine you are working with.
How to fix a misaligned crankshaft with camshafts?
When the cams are in position, then rotate the crankshaft to TDC and install the belt. Ooh, thank you, that is a tip no one else had for me. That even sounds like it may help with the pressure somewhat. Assuming the clearance for the valves or lack there of was increasing the pressure.
What happens to a crankshaft when the belt is off?
When the belt is off, there is no defined stroke. A stroke is defined by the direction of movement of the crankshaft in relation to the position of the valves. Since the valves are not being actuated because the belt has been removed, the stroke is not defined. You can remove the spark plugs, that will make rotating the crankshaft pretty easy.
Where do you put the timing disc on a camshaft?
It is always recommended to calculate the actual position of TDC rather than rely on the mark on the crank pulley. Fit the timing disc to the front of the crankshaft. A pointer for the timing disc can be made from a piece of bent wire secured under a suitable front cover bolt. Position a dial gauge to measure the travel of No 1 piston (see right).
Can a camshaft be turned without a belt?
However, both camshafts need to be lined up with the timing marks as well as the crankshaft turned to TDC before you install the belt to keep everything lined up correctly. My belt guide also shows this not to be an interference engine, so the cam shafts and crankshafts can be turned independently without causing damage.
What should the timing be on a Burton power camshaft?
Now rotate the crank clockwise until the inlet valve of number one cylinder is just off full lift position (such as 0.005” or 0.15mm). Record the figure on the timing disc from the pointer. Then continue to rotate the crank clockwise until the valve has fully opened and then closed by the same distance as previously used (0.005” or 0.15mm).
