Where do you put the timing disc on a camshaft?

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).

What should I look for before fitting a camshaft?

Before fitting the camshaft, check that it is identical in every aspect (with the exception of the lobe profiles) to the one being replaced. Special attention should be given to the oil feed positions and journal diameters as variations may occur during the manufacture of the engine.

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).

Can a performance camshaft be installed in an automatic gearbox?

The second section describes a typical method for timing a performance camshaft. Burtons do not recommend installing a performance camshaft in a vehicle fitted with an automatic gearbox. The installation and first few moments of running are critical factors in the life of the camshaft.

What are the timing tips for a camshaft?

Camshaft Timing Tips. EXAMPLE: To advance the camshaft, you install the crankshaft sprocket using the keyway marked A. Then you align the A mark on the outer edge of the sprocket with the dot marked on the camshaft sprocket, mark to mark. You must use the corresponding marks on the crankshaft sprocket for proper installation.

What happens when you turn the camshaft wheel?

Turn the camshaft wheel until you see the V-shaped timing mark at the top. If these timing marks are not aligned properly during assembly, the camshaft will be out of phase with the crankshaft and the valves may be damaged if they strike the pistons.

Which is the correct position to set the camshaft?

Otherwise known as “TDC”. This position is important when installing a new camshaft, because the cam must be set with the crankshaft at TDC. If the camshaft is off by a tooth, the engine will lack power and risks damage to the piston and valves. Search the outer rim of the flywheel for the T and F marks, in between 2 lines “|T F|”.

How do you advance a camshaft sprocket at Speedway Motors?

EXAMPLE: To advance the camshaft, you install the crankshaft sprocket using the keyway marked A. Then you align the A mark on the outer edge of the sprocket with the dot marked on the camshaft sprocket, mark to mark. You must use the corresponding marks on the crankshaft sprocket for proper installation. Cam Timing. Advancing.
