This tool wedges against the camshaft to apply leverage to mechanical lifters.

Availability: Out of stock. Compressing the lifters with the VW valve lifter tool allows the shims to be removed easily with the special pliers on this page. Not doing so is asking for serious problems! Do you understand what it describes? A more detailed explanation follows below the chart.

For other engines you will use the firing order that matches your engine to create a similar chart. This chart is based upon "opposite" cylinders of your firing order. You will notice that this is the same procedure and sequence as the intake valves listed above. Only now you are adjusting ONLY the exhaust valves the same way. TDC - Top Dead Center, or where the piston is at the top of the cylinder and both all valves for that cylinder are closed.

Lash - The clearance cooling time between the tip of the valve stem and the rocker arm. Zero Lash - No clearance, rocker is snug to the lifter. On a hydrualic lifer, the plunger is in the uppermost neutral position not compressed. In the chart above we see that adjustments are being made on "opposite" valves on the engine rotation cycle.

Small and big block Chevrolet engines use a firing order of What you are going to do is separate the order into the two sides of the firing order.

These are "exact" opposites that put the opposing valve at the correct location for adjustment, meaning the back side base circle, or heell of the cam lobe see image at left. Using the chart below common Chevy V8 firing order described above you will see that 1 is opposite 6, and vice-verse on the others cylinders in sequence through the firing order. This holds true for both intake and exhaust valves.

This procedure works on most V8 and V6 engines. The small chart below is showing you the opposite cylinders for a small or big block Chevy V8 engine with the above firing order. What this is showing you is a simple version of the above "opposite" list. For other engines, here are some common firing orders and their opposites. Do not rely on the below list. Importance of Lifter Position If the position of the lifter on the camshaft lobe is anywhere other than on the heel note image above where there is NO ramp contact when making adjustments, the lash setting will be incorrect.

Ensuring that the lifter is positioned on the heel of the cam lobe will guarantee that the valve you are adjusting is fully closed. Any other position and adjustments will NOT be accurate. Hydraulic Camshafts :. It is time to describe the actual wrench turning.

I was originally taught the wrong way too, both by instructors and by following inaccurate procedures in various shop manuals. When we followed these methods, our adjustment likely opened the valves slightly, preventing the valves from closing all the way!

Our valves were not set correctly! The typical hydraulic lifter requires an adjustment that is roughly half the available travel of the plunger. If an average hydraulic lifter plunger has a range of 0. This means that we must adjust the valves to fall between the depth that the plunger in the lifter drops. If adjusted too tight the plunger fully compressed the valves stay open slightly, and do not close all the way.

When the piston is at TDC, both exhaust and intake valve springs are unloaded, and valves are fully closed. Go ahead and remove it. Using a suitable deep socket and ratchet, turn the engine over while viewing the flywheel through the inspection hole. The simplest way to identify the power stroke is to watch the valve springs after the engine passes TDC.

When the valves do not compress immediately after TDC — You find the power stroke. The tools required are primarily basic. It comprises stainless steel strips of various sizes, measured and marked in standard and metric arranged in a fan configuration. On a bike engine, an off-set feeler gauge is easier to handle, might cost a few dollars more but totally worth it.

All engines will have at least two valves. Some will have four per cylinder. The intake valve s will be on the same side of the engine as the carburetor and the valve s closest to the carburetor. The exhaust valve s , likewise, will be the valve s closest to the exhaust.
